To any of us is difficult to imagine the living room without a sofa. This soft component of the interior gives people a feeling of warmth and comfort, the sofa in any house takes one of the most important places. People rest on it, play, communicate with family and loved ones, and also read, watch TV and sleep. In order to determine his choice, you need to clearly imagine what models exist and what functions they perform.

Now all the time there is more and more new corner models and structures for the house. In such a number of proposals, the buyer is quite difficult to decide on the choice and understand which type is suitable for it. In most cases, a person chooses a model based on its appearance and the material from which it is created. But with such indicators it is difficult to achieve full comfort in the use of the sofa. For example, this choice is suitable in order to furnish the room and give it aesthetics, but not to use it often. For the same goals there are monolithic sofas, they are called unrelaxing them. They can be seen in public places and shopping stores.

A completely different case when the sofa is bought for frequent use in everyday life. So, it can be assumed that such a model will be laid out every day for sleep . To choose the right model And do not make mistakes, you should know and understand which mechanisms for the transformation of sofas.

Other criteria of the selected model should also be provided: the size of the space required for the sofa, simplicity of transformation, the presence of a place where to give bed linen. It should also be determined for yourself what kind of sofas is better.

The classification of all sofas designs is carried out by:

1. Transformation.
2. Features of furniture design.
3. Appointment.
4. Size and capacity.

Types of mechanisms

Divan names

Classification by appointment

All models can be distributed by their purpose:

1. Office furniture.
2. Living room furniture.
3. Kitchen furniture.
4. Furniture for hallway.
5. Furniture for children's room.

With all these varieties, sofas and their mechanisms will significantly differ from each other, so it should be accurately decided on the design of the sofa and its purpose. In most cases Assignment can be determined by material from which furniture consists.

Those sofas that are covered with skin or more budgetary materials are usually located in the cabinets or in the kitchens.

Folding beautiful sofa is not just a piece of furniture in the living room. This is a multifunctional device that allows you to solve different tasks and compensate for the lack of space of the room. But many are many not aware that choose a sofa - not such a simple step, as it seems?

Healthy sleep is an integral part of the life of a person in which he spends about a third of the whole time. That is why the person's sleeping place must fully respond to his needs and requirements, be as comfortable and reliable as possible. Unfortunately, you can not always buy a high-quality soft bed. The main reason is the lack of free space indoors. Often, in a one-room apartment there is nowhere to put a chair - not what bed. Yes, and look in the common living room bed will be inappropriate. But the sofa, like any beautiful upholstered furniture, is an indispensable element of the interior of this room. From here, myself suggests the conclusion: you need such a sofa, which in the afternoon will be part of the decor of the living room, the meeting place and the pastime of the family, and at night will turn into a comfortable place to relax. And the option here is one - folding sofa.

But then the question immediately arises: how to choose a sofa in his apartment so that he fit into the interior and reliably served for many years, not becoming in the instrument of night torture. After all, as we remember, lay out and fold it for at least twice a day. In other words, it is necessary to find out which mechanisms have proven themselves as the most reliable, and which, on the contrary, are unsuitable for frequent foldings. And what are the advantages and disadvantages have sofas of one or another type? To date, the furniture range is represented by a huge selection of sofas with the most different types transformation. And each model has its pros and cons.

Consider them all.

1. Elf The easiest and most unassuming view of the sofa.

   
   

   It unfolds with the help of a simple lowering of sideline-armrests, which can be fixed in a convenient for the lying position. Such an opportunity to stay in the middleback position creates an orthopedic effect. This sofa is highly compact, although only one person is designed. In addition to this, it provides a box for sleeping facilities.

2. The sofa is clear from the name that this species is transformed by analogy with the disclosure of the book.

   
   

   To turn it into place to rest you need to raise the seat. The back will go down, taking a horizontal position. Then the seat is descended back. The transformation mechanisms of this type are considered the most enduring of all existing. In addition, these models at the bottom there is a bag for sleeping facilities. But they have some deficiencies. Due to the peculiarities of transformation, they will not be moved close to the wall. In addition, in the unfolded state, they are not particularly spacious. But the most unpleasant that there is a slot that prevents comfortable to sleep in time in the place of dusting the backs and seats.

3. Sofa eurobook. Despite the similarity in the title with the previous type, this model is described differently. The seat is extended or rolled forward, and a soft back is tipped into the released space.

   
   

   As a result, a very spacious place for relaxation is formed with a bag for sleeping facilities below. Features of the design allow you to tightly move it to the wall. And the simplicity of the mechanism makes its durable model of the previous type. However, in folded form, such sofas are inconvenient: the seat is too wide, therefore it is not very comfortable to fold on the back.

4. Sofa with tango mechanism (click-klyak)

   Tango (Click-Klyak) is a stylish sofa, which is an improved version of the "books".

   
   

   It unfolds on the same principle: the seat rises, lowering the back, after which it sinks back. A remarkable feature of this species are convenient folding sidewalls that can be lowered to increase the space of a bed or lift to make armrests. Another feature of this sofa is the ability to transform a back to a half-sided state. Despite the seeming complexity, the mechanism of this sofa is also distinguished by durability. Plus below there is a clothing storage compartment. However, like the "book", it can not be moved close to the wall.

5. Pantograph - this kind of sofa is unfolded according to the principle similar to the "Eurobook", except that it should be raised upwards to extend it, and then moving forward.

   
   

   After that, the backrest is also tipped into the vacant place. Thanks to such a design, it retains its advantages in the surface area, but in folded form on it is still not very convenient. Such a mechanism, although it provides ease of transformation, as well as an absolutely smooth surface of a rest space, significantly increases the cost of the model. But here there is a bag for sleeping facilities.

6. The Puma - according to the analogue with the previous type of mechanism, this is unfolded on the principle of lifting-extension of the sofa seat.

   
   

   At the same time, a soft platform rises to the released space from below, creating a single place to sleep and rest. Such models are beneficial for easy folding, but, as a rule, do not have a box for sleeping facilities. In addition, the backs of such models are separate pillows, which in the mode of space for sleep forever nowhere to do. Most often, this type of mechanism stands on corner sofas.

7. Accordion is perhaps the most universal model. It is disclosed on the principle of "accordion" by the extension of the seat that drags along and folds the back folded in half.

   
   

   As a result, a spacious bed is formed. Whereas in the folded state it is very compact. But such an advantage is poured into a significant disadvantage: there is a lot of space for the laid sofa, which will become a fatal square for the room. In addition, such a mechanism requires a considerable effort.

8. French clamshell - this option is unlikely to suit for everyday use, however, as an additional guest place is quite suitable.

   
   

   This model is usually replaced by pillows that are cleaned before transformation. After that, the seat is sequentially folded into three sections (on the principle of clamshells), forming a spacious place to relax. This type of mechanism is not distinguished by reliability. In addition, there are uncomfortable gaps that prevent comfortable rest between the decomposed sections. In addition, there is no box for linen.

9. An American clamshell - unlike the "French" analogue, this type of mechanism is more reliable and will withstand frequent transformation. It is described somewhat differently.

   
   

   First, a block with a folded component is put forward from the sofa housing. The seat of the retractable block rises, and the composite section is folded forward along the layer type and is installed on the legs. It turns out a spacious bed. However, there are not very comfortable seams between sections. In addition, there is no clothing compartment.

10. Spartak is a stylish sofa, the opening mechanism of which is similar to the "American folding bed". Before the start of transformation from the seat, pillows are removed.

    
    

    After that, the sofa block is raised from the housing, which, in turn, is laid out by two more sections that are installed on the legs. All sections are made of durable metal, which significantly reduces the weight of the structure in comparison with the standard elements of other types of sofas. However, such a design deprives the sofa ability to store bed linen below.

11. Picky - another type of mechanism, characteristic of both simplicity and reliability.

    
    

    The basis of the transformation is based on the retractable front part, on which there is a folded twice cushion. This pillow unfolds and stacked on the freed space. Spacious, and most importantly - deprived of the seams have a sleeping place. However, the height from the floor of such a sofa may seem too small.

12. Outdoor - perhaps the easiest and most economical view of the sofa.

    
    

    Consisting of two parts folding part in the folded state fits fully in the body of the sofa, forming its seat. Whereas, laid out, it is placed on the floor without legs or backups. The design is simple and therefore reliable. But, of course, there can be no question about the linen.

13. Conrad - model with a three-section mechanism. As a collected form, this is a beautiful and stylish sofa, and in the disassembled - a spacious place to sleep.

    
    

    It is transformed using the stretching of the seat, from which, in turn, the third section is put forward with the lifting part. As a result, the place to rest is not only large in the area, but also high. The mechanism of this model, although it has reliability, but heavy enough. But there are drawers for storing bedding.

14. Dolphin - a similar type of transformation is most often found in angular sofas. The principle of its action is the extension of the bottom section of the long side, followed by the lift of the pillow up with the help of a soft handle.

    
    

    As a rule, an angular sofa of such a design has a backrest consisting of separate airbags. Pillows have to be removed when laying a bed. The mechanism is distinguished by stability to loads, but it is quite quickly wearing. In addition, the carpet is hosted on the floor will greatly impede the extension of the section.

15. Kangaroo - the principle of operation of the mechanism is similar to "Dolphin" with the only difference that in the unfolded state it is significantly higher above the floor.

    
    

    However, this design loses reliability. And, like models with the type of transformation "Dolphin", this sofa is not distinguished by a long service life.

16. The advertiser is the most modern and progressive variety of transformation mechanism. It allows you to adjust the position of individual parts of the sofa - the tilt of the back, armrests, footrest, etc., thus creating an ideal place for relaxation.

    
    

    On separate more expensive models of such sofas, vibrorsasers are installed, adjustable using the control panel. In addition, the appearance of such sofas is the most solid and presentable. However, there are significant drawbacks and they. A full-fledged sleeping place on such a sofa is unlikely to succeed. Yes, and the cost of even the most simple models bite.

The choice, as we see, huge. So the sofa with which transformation mechanism is preferred? First of all, the family size should be taken into account. On one person, there will be a sofa with the mechanism "Elf" or some "books". Single, not constrained in the means and wishing to stylish and tastefully furnish, for example, a studio, you can spend on the sofa-advertist. If the family is very big, then the best option The sofas are spacious in the folded state - for example, angular. For a small family at the capacity, sofas of any other species will come.

On saving space, it is also worth navigating on the models, which, both in the folded, and in the unfolded form, do not occupy a lot of space. Also, preference can be given the model with lifting mechanism Box for storing sleeping facilities - space for blankets, pillows and plaids will not be superfluous. This option is especially relevant for sofas with pillows. Stand on options with unreliable mechanisms is not worth it. They will not meet your expectations. Accustomed to sleep on an ideally smooth surface of the bed should also be avoided by flaws and other varieties, in which irregularities are formed over time between the pillows.

Otherwise, the results of the choice will be focused on human preferences. After all, as usual: you go to the store or on the site, you see the sofa and you understand - he is what you need. And all these mechanisms, advantages and disadvantages depart into the background.

The sofa is the most used element of the interior. It is often exploited immediately in several appointments - for seating, rest or sleep. Therefore, choosing furniture, you need to take into account not only the appearance, but also varieties of sofas: classification, specifications. It will help choose a visual-beautiful model that will complement the interior, but at the same time will allow rationally to use the room space.

What are there?

Strict classification of sofas does not exist, but there are generally accepted standards and terms. Choosing a sofa, as a rule, take into account its design indicators, functional features and capacity. Characteristics can be highlighted in a separate list and rely when choosing its individual model, which will be especially important if the furniture is made to order.

In form

It is recommended to choose a sofa of such a form or design so that it does not occupy an unnecessary space in the room. This element of furniture should be located so as to fill out an unused area of \u200b\u200bthe room, and the passages or, for example, the play area in the children's room were free. According to the design of the sofas, it is conditionally divided into four types.

• Corner.Such models successfully occupy unused angular niches, direct backs can be led to the walls. Corner form Great for small-sized, one-bedroom apartments, small kitchens. In rooms with a large area, the angular construction allows you to zonate space.

• Direct or stationary- The most popular form of furniture due to the set of accommodation options. Straight sofas are conveniently installed along the walls, in the center and corners of the room, small compact models easily move around the room. Most direct sofas are folding or retractable. Mounted in the center of the room near the wall, they can, if necessary, serve as a full-fledged double bed.

• Modular sofas - The most mobile and multifunctional type of furniture, their design consists of several parts that can be used both together and separately. If necessary, the part are combined in a different order, for example, a large angular sofa is disassembled into two straight lines or small separate modules are used as ottomans.

• Island - These models are less popular in comparison with previous forms, as they are mainly involved in large rooms. Completed in the form of islands, they are so installed - in the middle of the room, or in the corner in the case of zoning the area. Island models occupy a lot of useful areas, but it looks presentable, help to embody bold design solutions.

Selecting the shape of furniture, it is important not to forget about its volume, the total area it will occupy.

The sofa in the hall or in the kitchen should not be too wide, in these rooms it is better to leave more space for movement. In the apartments where the folding sofa is planned to be used as a sleeping place, models with a wide seat are suitable, but for recreation rooms often choose the designs not only with wide, but also with a deep fit.

By destination

The shape and design of the sofa is also selected with the purpose of the purpose of furniture, the choice of material manufacturing material will depend on this indicator, as well as the total cost of the future product. For example, models with inexpensive trim are suitable for sleeping places, it is desirable to order sofas made from natural materials, in working or office premises, practical products covered with leather. By destination this element soft furniture Classified by five types:

• office, for workers' office;
• for the hall, living rooms;
• for kitchens and dining rooms;
• to a hallway or corridor;
• for children and gaming rooms.

If additional bedrooms are required periodically, it is better to choose a stationary direct view of the sofa, it is suitable for office space.

In places of recreation - in the living room, bedroom or dining room - good decision will be Modular version. Island models are convenient for zoning rooms - In the working offices, such sofas are places for informal conversation, installed in the halls in front of televisions.

In size

Under the sofa size is meant not only its actual length and width in centimeters, but also the number of seats (or sleeping, in the case of folding version). Compact models are usually designed for no more than 2-3 people, medium - 4-6, and huge modular sofas assembly can accommodate a company from 7 to 10 people.

However, when choosing a finished model, where the dimensions are laid by the manufacturer, it must be borne in mind that there is no single standard - one manufacturer may offer a double sofa with a length of 1.5 meters, and the other is 1.8 m.

An important indicator The size of upholstered furniture is the height of the back and landing. Sofas for hallways have a low back or are available at all without it, the models with a low rear wall and landing are also often installed in the halls and bedrooms. In places where the sofa is planned only to sit - in the kitchen or in an office room, they select such options so that the seating height is not lower than the usual chair.

The optimal choice for small premises will be sofa without side armrests and additional pillows, one more trick to reduce the size of furniture without loss of functionality - to purchase or order a design without legs. The possibilities of use will be somewhat limited, under such a sofa it is hard to clean up, But it will be minimized.

Types of transformation mechanisms

From the type of mechanism and method of changing the design will depend on the place of possible installation. Some models may occupy little space, but during transformation they need much more space. The choice of a sofa layout method also affects the purpose of furniture, the frequency of its use is not all types of mechanisms are intended for frequent operation. It is necessary to take into account the alleged weight, which will be on the furniture in the unfolded state. therefore All sofa models are divided into four main types by the name of the transformation mechanism.

Picky

Assembly, the design of the roll-out model consists of three individual elements - The rear of the folded state is a back, and after the transformation, the horizontal position becomes a place for the head. As the main lying place, the node part is extended forward and hidden in the design.

Such models of upholstered furniture are also called - Sofas with a transformation mechanism "Telescope", Because the layout is made from the inside, like the telescope, individual parts are put forward and fixed with each other. Retractable versions are mainly installed in large rooms, since in the decomposed state the width of furniture increases more than three times.

Transformation of the discarded design is made in several stages.

Initially, it is necessary to pull for a rag handle located in the lower transverse part of the planting place, and push the entire seat frame out. Then it is necessary to align the bedroom surface of the furniture, lowering the back wall. In some models, additional submissive pillows are used for these purposes - in the assembled state, they perform the role of a second soft back. The retractable mechanism on such models, as a rule, is based on the roller system, less often - special springs are built into the design, which fold the seats after the lower part is extended.

Sliding

In the collected form, sliding models are very elegant and compact, and in the unfolded state resemble a clamshell. After transformation, the front part is installed on special discarded supports, the back is lowered, and in assembly, the bed becomes three separate sections. There are several basic types of sliding products.

• "French" clamshell- Classic version of sliding upholstered furniture. As a collected form, it takes little space, but when layout, the front part is advanced forward by one and a half or two meters, depending on the specific model. "French" mechanism is not recommended for frequent use - as a sleeping sofa can serve only occasionally, basically such models are more designed for seating.

• "American" clamshell.According to its design, it is similar to the previous model - sleeping places are formed from three sections that are put forward in turn and are installed on special supports. The main difference is that in the "American" version, a more reliable and durable mechanism is used - furniture is designed for frequent operation. However, the cost of such sofas is significantly higher.

• "Italian" clamshell. Unlike previous varieties, the "Italian" clamshell is transformed not by the lifting of the transverse beam of the seats, but by extending the rear wall of the sofa. Then the sliding mechanism is also driven, and the surface is installed on the support legs. Compared to the "American" and "French" analogs, furniture with the "Italian" type of mechanism is equipped with more durable legs.

The most common modifications applies and the mechanism of type "Accordion". The principle of his action is that, moving forward, sleeping places as it were stretched with special springs. Metal spring elements, fixed on both sides of the structure, also help to fold the sofa - they delay the sections inside, setting each in their place. For the transformation of these models, minimal efforts are required - it is only necessary to slightly raise the bottom beam of the seats and push it forward.

Just like model-clamshells, "Accordion" has very compact sizes in the assembled form, it is conveniently installed in small rooms. Another important plus is the presence of a linen stand in the rear wall of the furniture. The sliding mechanisms "Accordion" are equipped with reliable working elements, have a long service life, withstand considerable weight, simple in transformation, but they have a disadvantage - when spreading supports slide on the floor and can damage the coating.

Lifting

Upholstered furniture with a lifting mechanism consists of two identical parts and assumes only two positions - a seated sofa and a sleep surface. The horizontal transformation is performed by lifting the seats and fold back the backrest. She stacked on wooden frameAnd the beam of the seats falls into its place, in the raised state the rear wall is fixed by special locking mechanisms.

Before installing, it is necessary to take into account that between the sofa and the wall will require 10-15 cm of the empty space for the back, when it will be in the lowered position.

Swearing

Sofas with a swivel mechanism Some of the first appeared on the furniture market, they are compact and very easy to operate, therefore always remain relevant. In the design, the minimum of elements is involved, there are no brittle parts, rollers. Important plus - the presence of a box for linen. Of the minuses - between the sofa and the wall should be a distance of 10-15 cm, necessary when placing, - the seats rise, and the rear wall leans back, forming a place for the head.

Thanks to the stoppers, the back back can be deployed, fixed in the middle position, so the models are called rotary.

Buying a sofa for home or cottage, special attention should be paid to the device for its transformation. It depends on the organization of the sleeping space and durability of the model. Today, the mechanisms of transformation of sofas are very diverse. They are developed taking into account the area of \u200b\u200bpremises, they often easily turn the sofa into bed. Even the child of adolescence can cope with them. In order not to be confused when choosing, you need to know the principle of operation, the features of each device and the degree of load on the furniture frame.

Types of sofa mechanisms for the type of transformation

Three types of sofas can be distinguished, which use special transformation mechanisms. They can be:

• In direct models - representing the usual design from the main part with armrests or without a lounge box (and in some embodiments, the box in which the bed of the bedroom is located).

• In angular structures - from angular elementhaving its own functionality in the form of a niche, a roomy box for bed linen or other things. It allows you to save space in the closet.

• In island (modular) systems - structures consisting of separate modules, different in areas, but the same in height (depending on their amount they change their functions).

The sofa name is obliged to the transformation mechanism. Although companies come up with an interesting name for each model, the basis of the title, characterizing this or that model, is the principle of operation of its mechanism.

The device does not change - regardless of the type of model (direct, modular or angular). The sofa is folded forward, sometimes it raises up, rolls out, extends, rotated. If it is a direct form, the base is transformed, in the angular version, the sleeping unit is added to the corner, forming a rectangular recreation area. In modular structures, the direct part of one module is transformed without affecting others.

The work of any mechanism is not as complicated as it may seem at first glance. The principle of operation of structures is different and has both pros and cons. Most of them can approach all types of sofas (direct, angular, modular). For them, the presence or absence of model armrests does not matter. However, there are systems of transformation that are only suitable for one type.

Sliding and knotted

Rewind forward models are convenient, they are compact in folded form, do not occupy a lot of space, do not create the impression of the climbing room. The principle of their work is to roll out the block forward and raise to the desired height. Sliding structures They are models whose details are interdependent, therefore, when transformed, one automatically involves the other.

"Dolphin"

One of the universal models with a fixed back and a simple transformation device, which allows you to arrange a sofa in the center of the room or close by the wall.

To decompose the model, you need to pull the box of the box located under the seat in which the missing bed section is located. When the block is extended until it stops, it is raised by the loop, put in the desired position at the level of the seat. This design forms a spacious and convenient surface for sleep, withstands a large weight load.

"Venice"

The principle of operation of the roll-out mechanism resembles "Dolphin". First you need to put forward to the stop section located under the sofa seat. When moving the transformation device, slide the seat unit, increasing the width of the sleeping bed. After turning out the block until it is stopped, it is raised to the height of the seat with the help of loops.

Such designs are convenient. They are often found in corner modelshave a lot of free space in angular elements.

"Eurobook"

Advanced "Book" is a great option for daily use. It is equipped with a reliable and easy-to-use transformation mechanism, resistant to daily loads and allowing the sofa in the center of the room or the wall.

To carry out the transformation, you need to take the seat, slightly lift it, pull it forward and omit to the floor. Then lower the back, forming a bed. Such furniture rarely has a spacious sleeping bed: it is compact and folded, and disassembled.

"Conrad"

A device that in some manufacturers is called a "telescope" or "telescopic", is a roll-out model. To make a bed from such a sofa, it is necessary to pull the selection section, raise the base, then remove the cushion in the box, close the base and arrange mats on it, deploying them as a book.

The design is convenient and allows you to organize a spacious bed, without pushing the sofa from the wall. The surface of the floor should be smooth, as well as for all roll-out mechanisms, so the carpet aligned to the floor can cause the transformation system failure.

"Pantograph"

The design known as "Tik-so" is an option with a walking mechanism. She is an advanced version of Eurobooks. For transformation, you need to pull the seat forward with the help of loops, lifting it. At the same time, it will adopt the position itself, dropping down. It will remain lowered the back, forming a spacious bed for two.

In some models, the manufacturer has provided additional armrests that limit the rest area. Such a device is durable and not overlays the body of the model. However, options with a soft back are not very comfortable. To decompose such a sofa, it will have to move away a bit from the wall.

"Puma"

Such a model is a kind of "pantograph" - with a little difference. As a rule, these sofas the back is low and fixed, so such models can be placed in the wall, thereby saving the useful area of \u200b\u200bthe room.

Transformation is carried out by one seat extension - in contrast to the previous mechanism. When it is raised and, dropping, falls into its place, at the same time with this below (where the seat was located before) the second block section was rising. As soon as the seat rises in place, two blocks form a full-fledged sleeping bed.

"Saber"

A convenient dying "Sable" mechanism provides for a change in the size of a sleeping bed with full or partial decomposition. This design is distinguished by a liner, a high place to sleep.

The sleeping place of the furniture can consist of two or three sections - depending on the model. To decompose it, in any case, you need to roll out the seat under which the linen box is located forward. At the same time, the back is leaking back, stacking into the right position.

"Goose"

The original output transformation system, for which you need to first roll out from under the seat block of the bedroom, and then raise it to the seat level. At the same time, due to the peculiarities of the pillows rise to the back of the structure, there is an increase in the bedroom.

The assembly and disassembly of such designs take longer - compared to other systems.

Such a model is quite complicated and not suitable for daily use. But in the folded form of the model with this system, they are very compact, they look carefully, so they can be performed as a soft furniture for the cottage or living room.

"Butterfly"

Transformer sofas with the butterfly system are considered one of the most reliable, durable and durable. Today, such a system is very popular among buyers. It turns the sofa into the bed literally in a few seconds. Transformation is carried out in two stages: the seat is rolled forward, then the upper block is folded back (on the extended rear section).

The advantage of the model is the significant size of the sleeping bed in the unfolded form and compactness in the assembly. The minus of the mechanism is considered vulnerability of rollers during transformation, as well as a small height of the sleeping bed.

"Kangaroo"

The mechanism of transformation "Kangaroo" resembles the Dolphin system - with a little difference: sharp movements, similar to Kangaroo jumps. It has a lower part located under the seat, which, when placing, is easily advanced forward. The retractable block rises to the desired place, touching the main mats tightly.

The main thing that distinguishes such a mechanism is the presence of high metallic or wooden legs. The disadvantages of the system include a short period of use with frequent transformation. This design can not be called reliable.

"Hessen"

The device of this mechanism resembles the Dolphin system. To decompose such a sofa, you will need to first pull for the loop of the bottom section under the seat, extend it until it stops. This will roll out the seat. Then the block is raised at the height level of the bed, lowered the seat mat, forming a full-fledged bed of three parts.

This system is applied in direct and corner sofas models. However, she also has its own disadvantages, because with constant turning blocking the block creates a large load on the sofa frame. In addition, if you do not take care of the rollers, the mechanism will have to be repaired after a while.

Folding

Mechanisms with laying sections are not more complicated. Usually they are based on the most versatile systems ("frog"), so do not require more than a few seconds to convert the sofa to a full-fledged bed. For their transformation, you do not need to roll out sections from under the seat.

"Click-klyak"

The design of such a mechanism has the second name - Tango. Some manufacturers call it "Finnish". This is a double-fold model, an improved version of the classic "book."

To decompose the sofa, you need to raise the seat until it clicks. At the same time, the back falls back, the seat is somewhat moving forward, opening two half of the block into a single surface for sleep.

"Book"

The easiest transformation mechanism resembling the disclosure of the book. To make the sofa take the form of the bed, you need to raise the seat, lowering the back. When the back is starting to descend, the seat move forward.

"Scissors"

The transformation mechanism of the angular sofa, the principle of operation of which consists in turning the same section to another - with laying blocks and reliable fixation of the sections with metal fastening from the bottom. At the same time, a compact sleeping box is formed with a bedside table, open as a result of transformation of sections.

"Caravan"

The design, the decline of which is similar to the Eurobook system, but it remains a fixed back, and instead of two sections of the sleeping box, three are laid out. At the same time, the seat is also raised and simultaneously pulled forward, then lowered to the right position to the floor. At this time, the next, folding together in a single area for sleeping from each block. Convenient design with a spacious seating area. In some structures, instead of a third section, a folding pillow is used, which is faced with a fixed back.

"Daiton"

The system with folding fixed pillows performing the back function. The device of the mechanism is a little similar to the "clamshell". To transform a sofa into bed, you need to raise the pillows to the top position, then put the bottom in the designated places, take the handle and deploy the seat block down, opening the bed of two or three parts. When the sleeping place is decomposed, you will need to lower the pillow, wrapped them on the bed.

"Tornado"

Folding mechanism designed for daily operation. The basis of the design is the "clamshell" of double addition, which is hidden in the usual position of the sofa. It is transformed without removing the seat, after tilt the backrest model. The design is convenient, it is not very difficult to disassemble, it has steel elements and a grid at the base, as well as matte moderate stiffness.

Deployable

The following devices provide transformation by deploying sections. In most models (with the exception of the "Accordion"), the back is fixed and does not participate in the disassembly of the sofa.

"Accordion"

The device of the mechanism resembling the stretching of the harmony fur. To decompose such a sofa, you just need to pull the seat. At the same time, the backboard consisting of two blocks connected from above will automatically drop down, laid out on two halves.

"Belgian clamshell"

This design is similar to the "clamshell", hidden under the modular mats of the sofa seat. Even an externally, the system reminds all familiar piece of furniture with metal supports. The only thing that distinguishes it - it is fixed in the base of the sofa and turns straight from it, turning the seat block down

"French clamshell"

Alternative to the "Accordion" system - with the difference that in the latter bed, folded from three blocks (according to the principle of folding the fan), and in this system, the blocks are wrapped in and when unfolding unfolds. They are equipped with supports and have non-stuffing type, which is a minus such designs.

When going to decompose the sofa, you need to remove modular pillows from the seat.

"American clamshell" ("Sedaflex")

Such a mechanism is more reliable than its French analogue. No need to remove pillows with seats before transformation. The system involves identical sections (three of them), which unfold in each other when picked up the seat. Such a mechanism is quite durable, but it is only suitable as guests, After all, it has thin mattresses, the underwear compartment is not provided and steel structural elements are felt at the joints of the sections.

"Spartacus"

Option with a mechanism on the principle of "clamshells". Folding construction Located under the seat consisting of modular pillows. To the sofa become a bed, you need to remove the pillows, freeing the blocks of "clamshells". Since they are in a wrapped position, first take the top, set the desired position by setting the metal support, and then unfold the rest of the sections. This design is not designed for daily transformation - as the analogues.

With a swivel mechanism

Models with a rotary mechanism differ from other systems with ease of transformation. They are minimal on the framework on the frame, as there is no need to roll out the sections until it stops. They do not need an approximate blocks.

It may turn as a solid part of the sofa and the component of each block - depending on the model. Such a mechanism is used in angular models, connecting two halves of sections with blocks into a single bed. The principle of operation of the system is based on the rotation of the half of the block by 90 degrees and turning it to another part of the sofa (followed by fixation).

With folding armrests

Folding armrests - Unique reception mechanism of transformation. Today, such sofas are the focus of designers. With their help, you can furnish the children's room, if necessary, adjusting the furniture dimensions.

"LIT"

A peculiar design that allows you to resize the sleeping bed due to the deformation of the armrests. At the same time, the sidewalls themselves can be positioned at any angle - and even positions may be different. To transform a sofa into a single bed, you must first raise the armrest inside until it stops, and then bent out. These designs are designed for direct varieties of sofas, they are bought for children and adolescents.

"Elf"

Comfortable for small-sized premises and children's rooms System, a large area for transformation is not needed. Furniture can be put on the wall. Such a sofa can be compared with its analogue, it has a compact case and a spacious storage space bedding. The surface of the seat and armrests make up a single block, which is folded in length.

With advertisers

Such mechanism devices are somewhat more complicated by the rest. Moreover, the design of the mechanism allows you to easily change the position of the angle of inclination of the back and footrest, creating the most convenient position for the user. This sofa can be equipped with a massage mechanism, it has a rather solid appearance, but the transformation into bed is not carried out.

Double and triple systems

Transformation mechanisms may vary. As a rule, the more complicated the mechanism, the larger the components of the bed (the number of additions). The sofas of folding and retractable types fall into this category.

What is better to choose for daily sleep?

Choosing a sofa for daily operation, you need to pay attention to the designs in which the load on the frame during the operation of the mechanism is most uniform and does not overlook the case.

It is necessary to choose not only the mechanism, but also the degree of stiffness of the back, seat. You also need to choose a good upholstery material and pay attention to the models with the possibility of changing covers.

Filling blocks

Choosing a sofa for daily sleep, it is worth considering the filler block. It happens two types: spring and flawed.

The first embodiments are distinguished by the presence of springs twisted form (position - vertical). You can allocate dependent and independent types. In the first case, the sofa fuses down. Such mats are unreliable in that they do not have proper support of the spine during rest or sleep (in the sitting position and lying).

Independent type springs do not come into contact with each other, so each of them works independently, not forcing others to fuse where it is not necessary. As a result, the back always remains smooth, and the load on the spine decreases.

Flameless mats are distinguished by a wonderful orthopedic effect, it is the prevention of the problems associated with the spine. They are not only safe, but very comfortable, provide a full and right vacation during sleep.

This type of hypoallergenic filler, this packing is not affected by the formation of fungus, mold. It is resistant to the accumulation of dust, because there is no significant voids. The best flawless fillers include natural or artificial latex, coir (coconut fiber), HR type PPU.

What's better?

In order for the sofa to serve for a long time, it is better to choose a high-quality type of filler: a block with independent springs, latex or coir. Very good, if the type of mat will be combined - when not only the core of the packing, but also another material (to give the desired stiffness).

If the latex unit is not suitable for the budget, it is worth paying attention to the furniture polyurethane foam type HR or synthetic latex. These materials are somewhat inferior to expensive navigations, but it is enough to be enough for 10-12 years.

As for the transformation mechanism, the Dolphin designs and their analogues are not suitable for daily use, models with a clamshell system. The most reliable designs for every day are considered to be "Eurobook", "Pantograph", "Puma" and turning mechanisms.

How to choose a mechanism?

It is impossible to unambiguously allocate one mechanism. The choice depends on several factors:

• reserved seats for the sofa (folded and disassembled);
• sofa destinations (guest versions or bed alternative);
• load intensity modes (weight control taking into account the choice of "correct" seats and backs);
• simplicity and convenience in work (the sofa should be light, because complex systems break more often and are not always subject to recovery);
• the correct diameter of steel elements (at least 1.5 cm).

For the purchase was successful, the sofa was enough for a long time, it is worth paying attention to:

• the impeccable course of the mechanism in the work (it should not eat);
• the absence of a construct breaking during transformation (this is a clear marriage that reduces the life of the sofa);
• lack of rust, scratches, dents, mechanism assembly defects;
• qualitative upholstery material that will not be emitted from the frequent transformation of the sofa (when the sections are coming);
• strong and durable metal mechanism resistant to large weight loads (two or three people);
• reliability of the components of the framework, to which the transformation mechanism is attached.

It is important to choose the mechanism in which there is no complicated design. It will be less prone to breakdowns.
