I suggest you get acquainted with the most common mechanisms for transformation of the sofa in a bed. You will learn the pros and cons of everyone and you can choose the form of a sofa sofa suitable for you.

• Book

  Familiar to everyone from Soviet times the type of sofa layout. Externally, the sofa reminds the revealing book.

  Pros: In terms of competent execution, forms a sufficiently comfortable sleeping place. Big box for linen. It is possible to use high-quality spring filling. Suitable for daily use.
  Minuses: Design restrictions - seats and backs are a sleeping place, which means there must be even and close to rectangular form. Sleeping is narrow. If the model increases the width of the bed, then when laying, you have to move the sofa from the wall, which is already inconvenient. A large number of mechanisms of different manufacturers. When the "Book" mechanism exits, it is not always possible to find a suitable replacement.

• Click-klyak

  Upgraded "books". In addition to the provisions "for lying" and "for seating" has a third intermediate option "midway". Do not confuse with "Tik-so" is a completely different mechanism.

  Pros: There is a box for linen. Suitable for daily use. Only two types of mechanisms (locks) - it is very easy to pick up and replace if it fails. It is also easy to replace wooden sofa base lats.
  Minuses: The same as the "book" - the need to move the sofa from the wall during laying, restrictions in design. It is performed on metal frame with wooden lats (lamellas), which are broken with point exceeding the load. However, broken lamellas in such sofas simply replace new lats.

• Eurobook

  Perhaps the best option if you need a sofa bed for daily use. It has all the advantages of "books", but deprived of its minuses.

  Pros: Enough reliable mechanism, as a result, its simplicity, or rather there is no lack (ordinary loops are used). Broad sleeping place. It is possible to use high-quality spring filling. With competent execution, there is no need to move away from the wall. Large linen box. The best way for daily sleep.
  Minuses: When folded, you must use additional pillows for the back.

• Tick-like (he is a pantograph)

  A variety of "Eurobooks". It is distinguished by the fact that the seat is not rolled out on the wheels, but steps forward using the mechanism with springs.

  Pros:This is the same eurobook, only there are no wheels on the floor.
  Minuses:Unlike the usual Eurobooks installed the mechanism of walking, which makes the product more expensive.

• Accordion

  There is a mono modification of this type of mechanism. From ordinary loop based and wooden Lamps Using the "Book" lock mechanism to factory all-metal frames with birch lats.

  Pros: Any width of the bed. Suitable for daily use.
  Minuses: Restrictions in design. It is rather a "youth style".

• Dolphin (he is microlift)

  Easy to use mechanism. Most often used in angular sofas.

  Pros:Just folded. Reliable enough. With proper implementation suitable for daily use.
  Minuses: There is no linen (in angular sofas, it is usually compensated by the presence of a side drawer). Often, manufacturers are put on the rolling part of a significantly more subtle filler (foam) than on the other parts - to sleep on such a design is inconvenient.

• Picky (he is a telescope)

  10 years ago it was a very common system. It has several modifications.

  Pros: Easy folding. As a rule, there is a small box for linen.
  Minuses: Frequently comes out of order fittings. In the overwhelming majority of models, strong differences over the thickness of the pillows across the bedroom, as a result, reduced comfort. Sleeping low. This is the speed of the guest version, and not for daily sleep.

The sofa is one of the most convenient furniture items. It is unlikely that something else compares with him by the degree of comfort. It is much more functional than bed. Due to the fact that there is a sofa laying mechanism, you can arrange an extra bed for an adult or child.

The perfect option for lovers of modern practical style.

Most apartments allow you to put such a piece of furniture without prejudice to free space. During the day, the sofa usually performs the role of a convenient seat for seating, like a chair, but it can also be "half-up", and even sleep if suddenly the dream smorhes you in aptural time.

It is spacious with its enough compact sizes, so it is appropriate in the room of any square.

The usual furniture has many modifications today. The owners of commercial institutions, and the owners of apartments and the inhabitants of country cottages are chosen.

Sofas are divided into a number of types, depending on the purpose:

• kitchen;
• for nursery;
• for the living room;
• for office;
• for hallway.

Compact, he, at the same time, will provide you with a full place to relax.

Mechanisms of transformation of sofas for living rooms and children provide an increase in comfortable space. If necessary, it turns into a sleeping place. The child can play on the floor, and then lie down to rest or read.

In contrast to most corner models It has a comfortable seat for seating and two sidewalls with wooden armrests, which ensure the comfort of the whole family while watching TV or just rest.

Office, kitchen and models for the hallway usually do not have additional folding parts - the mechanism of transformation of the sofa is missing in them, because the visit to these places does not imply overnight stays.

Types of sofas on constructive features

A variety of designs allows you to choose stylish and practical sofas to your liking.

There are several types of structures that differ in shape:

• angular;
• straight classic;
• island.

Universal sofa, because by transformation using a simple roll-out mechanism turns into a comfortable double bed.

Furniture corner form Convenient for small rooms, where there is a free bog of two walls. Such sofas occupy a minimum of space can have additional modules (removed when necessary).

Spring unit and filling of polyurethane foam, environmentally friendly safe material, Provides an anatomical body position during sleep, thanks to which the rest is full and healthy.

A straight line is usually located at one of the wide walls. Sofa layout mechanisms with a similar design are not available for all models. To provide an extra bed, you need to choose furniture with layout system.

Amenities The sofa adds a niche for linen in which you can store bedding.

Types of island-type sofas can be different. The modules are folded into the desired position, providing a wide area for rest lying.

Long service life even with intensive exploitation is possible due to a wooden frame.

Types of transformation sofas

The type of sofa laying significantly affects the degree of comfort. If the sleeping place is planned large, then you need to choose the design on the basis of the area and layout of the room.

The original design of the sofa and its carefully thought-out forms will become a wint of the room.

Sofa transformation mechanisms dictate type layout:

• "Book";
• "Tango";
• "Lit";
• "Dolphin";
• "Puma";
• "Pantograph";
• "Clamp", etc.

This is one of the most popular mechanisms today.

When choosing, it is necessary to proceed from how much the layout for the forces of family members, because tight and complex mechanisms may also have any physical costs for them.

Based on its bedroom - a high-quality spring block, which allows the child's spine to stay in an anatomically correct position, so without being curving

Mechanism of transformation of the sofa "Book"

One of the most popular types of sofas. Bringing the design in a horizontal position takes a minimum of time. You need to pull the seat on yourself, and raising it until the lever is triggered, you can easily spread the sofa for sleep.

While the child is small, the sofa can be used without folding.

The mechanism of transformation of the sofa "book" is reliable and simple because it provides a sleeping place very quickly. It is possible to operate the furniture for a long time without loss of performance.

The sofa book combines the dignity of the classic sofa and modern functional solutions.

Types of sofas transforming for convenient position and sleep:

• straight;
• corner (Eurobook or Tango).

It has practical armrests, a high and comfortable back.

The latter have a shorter head, the long (narrow) folded into the head with the head - it turns out a one-piece area for a comfortable stay. The mechanism of transformation of the Tango sofa is similar to the layout mechanism of a direct "book". It is necessary to pull the seat on itself and up clicks.

Filling - high-quality safe polyurethane foam with spring block.

Sofa Click-Clak: Elevated Comfort

The view of the sofa, on the principle of layout resembling a "book". To bring the bed in a horizontal position, you must pull the seat up to the characteristic sound.

The transformation mechanism of the sofas-click sofas is as simple as the previous type.

To lay the sofa in a horizontal position for subsequent sleep, it is not necessary to make great efforts, unless the design is not strongly deformed from a long operation.

The sofa will perfectly take its place in the living room, or the bedroom.

This sofas transformation mechanisms are one of the easiest. Often such models can be seen in a teenager room or bedroom.

The sofa will provide an extra bed, if the relatives or friends arrived.

Sofas "Lit" and Picky Type

Two types of structures - "lit" and roll-out are also very popular due to the rapid decomposition for sleep. Transformed Sofa "Lit" is easy. Armrests can be placed for children's bed, and to arrange a comfortable sleeping place for an adult. To bring a sofa to the right position, you need to pull the seat on yourself by fixing it after the lever is triggered.

Retractable furniture does not require an application effort, the load goes to the rollers. When moving on itself, parts are transformed into a horizontal position, it remains only to align them and place for the convenience of the pillow. The sofa provides an extra bed for adult or two - for children.

Filling - high-quality safe polyurethane foam with spring block.

Mechanisms "Puma" and "Dolphin"

The type of layout "Puma" is also the leader among simple control systems sofa mechanisms. In a horizontal position, the design leads in one or two movements. It is enough to pull on yourself until it stops - an additional part will appear, before that hidden inside. The third part is filled with the back.

A sofa with the "Dolphin" mechanism is different. The difference is that the additional unit is extended from the bottom of the furniture, which then becomes clove with the surface. The sleeping place is large, and in folded form, the object of the situation is very ergonomically.

With the help of the mechanism, you can easily spread the sofa, having received a full-fledged double bed, while there is a spacious linen niche for your convenience.

Selecting a sofa depending on the size of the room

By purchasing folding furniture, it is necessary to focus on the area of \u200b\u200bthe room, where it is supposed to put it.

• For children's rooms, the sofas of the single layout of the "book" type, "lit" or roll-out are suitable. The size of the sofa is also important. For children, choose a situation in specialized stores, since there are strict environmental certification. Furniture will be safe and from the point of view of mechanics.
• For living rooms and bedrooms of large sizes and with square layout, double laying sofas are convenient. They provide if necessary, replace bed, and you can accommodate with great convenience.
• Folding sofas - a wonderful alternative to beds in country housewhere there are some small guest rooms. In the afternoon they will be able to sit, reading a book or watching TV, and at night - to sleep comfortably.

Elegance add spectacular wooden legs.

Quality of mechanical parts

When choosing a folding sofa, give preference to the proven manufacturers, and in the store repeatedly check the mobility of the mechanisms, since typical models may contain defective parts. If the mechanics are tight, there is a feeling of the breaking of the guides - the question of a small control over the quality of the manufacturer arises.

The optimal option will be the manufacture of a sofa to order. With this approach, you can not only purchase a qualitative thing for individually declared sizes, but also to control the course of work. In most cases, you also avoid overpayments. Furniture will pass careful control, before you get it in the finished form.

The sofa will perfectly take its place in the living room, or the bedroom.

Sofa operation

Despite the warranty, an outstanding sofa manufacturer, under certain impacts, it may be in disrepair much earlier. You need to handle the folding sofa - try not to pull the folding parts and do not take them on the parties, loosening the transformation mechanism.

Since the hinges and levers are most advantageous, they do not tolerate excess moisture. Therefore, when cleaning the sofa, try to use the squeezed sponge or slightly wet brush. Eating caustic detergents The mechanisms are able to cause metal corrosion.

The base of the sofa frame is made of natural wood, the case material is high strength Fiberboard.

Video: How to choose a sofa? Video review Transformation mechanisms, filler, upholstery

For rational selection of the sofa, it should be led to what kinds of sofas exist. What are their differences, dignity and disadvantages.

There is no strict classification of sofas species. In this review, I will be guided by the fact that the sofas can be classified depending on their design and functional (destination of the sofa) features. So, let's go.

Which sofas are depending on the design

In this section, I chose the most significant design differences in sofas species. These include

• the ability of the sofa to change the shape and size without folding - in this part I divided sofas to stationary and modular
• the ability of the sofa to transformation - decomposition
• varieties of sofas depending on the type of filler
• types of sofas depending on the fabric for the upholstery of the sofa (I consider this indicator least significant)

Now about every constructive difference in sofas in detail.

Stationary, modular and island types of sofas

On this basis, the sofas can be divided into three groups - stationary, modular and island. We will understand what better.

Stationary sofas

Stationary sofas are sofas that have fixed dimensions. They do not allow changing the form and size of the product. The stationary sofa is located along the wall. The rear wall of the sofa has a more economical finish (for example, felt), which differs from the main upholstery.

In turn, stationary sofas can be divided into:

Straight sofas- Usually used B. small rooms. There are folding and not folded

Corner sofas - also there are folding and non-folding . Hungary sofas require more space.

• To advantages Stationary sofas can be attributed to the fact that during laying the sofa turns into a comfortable sleeping place. You can use such a sofa as for seating and for sleep. Prices for such sofas are also quite lifted.
• Disadvantagestationary sofas is a certain massiveness and not the possibility of changing shapes and sizes.

Modular sofas

The modular sofa consists of parts modules that can be combined in different order and create a single product. You can also use sofa modules as independent furniture elements.

Of course, such models are mobile and will suit creative personalities. You can change the configuration and general view of the sofa. Due to the compactness of the sizes of modules, modular sofas are convenient to move and transport.

• Advantages of modular sofas Mobility in all senses, transformation and change general view Product
• To disadvantages It is possible that such sofas often do not have a bed and have a higher price than stationary sofas, the range of modular sofas on sale is much smaller than the range of stationary sofas.

This type of sofas are used to organize leisure places. At the same time, the sofa is not located along the walls, and in gave them from them. Divan is formed the semblance of the island. Island sofas have an attractive view from all sides. In shape, they can be round, semicircular, oval and rectangular. Using the island sofa suggests the presence of sufficient free space in the room. The approach to the "island" must be free from all sides. Island sofas have different sizes. From one or two local up to 5-6 local versions.

• Advantages of island sofas Mobility, stylish and unique appearance
• disadvantages Sofas do not have a sleeping place, require large spaces, have a high price

Output: If you need a sofa for organizing a bed, then you need a landline sofa view. If you want to organize seats and day rest, look at the modular versions. The island sofa is good in case of having a large space indoor

Design features of sofas allow you to create sofas of various forms. Detailed description The sofa forms in this article.

Types of sofas depending on the ability of transformation

Sofas are folding and not folding.

This type of sofas contains a transformation mechanism in the design, which is located inside the sofa housing. The mechanisms of laying sofas are more than a dozen. Details of all transformation mechanisms can be read

In folded sofa, the mechanism is not visible. The mechanism allows you to convert the sofa size. Usually, folding sofas are needed to organize a space for sleep. Store sofas can be both angular and straight.

• The advantages of folding sofas The possibility of transformation increases the functionality of the sofa-afternoon sofa, at night the bed. Folding sofas may contain additional linen boxes hidden inside the sofa
• Lack of folding sofas associated with the reliability of the mechanism itself and the sofa frame. If the transformation of the sofa is frequent, then its wear is increasing. It is easy to carefully choose a reliable mechanism and a high-quality sofa frame when purchasing it.

Sofas are not folding

From the title it follows that this kind of sofas is not transforming anything. Similarly, similar models are used to organize seats. Non-folding sofas can be used by a pair and or with armchairs, creating a recreation area, for example around a coffee table in the living room. Mindly such a sofa will work in your kitchen or in the dining room. If it allows the area, then you can use it and in the hallway

• The advantages of non-folding sofas:compact sizes, low price
• Disadvantages of non-folding sofas:weak, limited functionality

Output: If you need a multifunctional assistant, as in advertising everything in one bottle, then you need folding sofa. If the functions are more modest- only to sit, then you can significantly save by purchasing not a folding sofa.

Types of sofas depending on the type of filler

On this basis, two main groups can be distinguished.

Sofa fillers based on spring blocks

In such sofas, the filler performs the design made on the basis of metal springs. Springs can be associated with blocks or independent. Also, the spring unit may have a common frame from the metal. This kind of sofas is good for sleep. Spring blocks have a long service life and comfortable during operation.

Sofas with filler without springs

As a filler without spring sofas can be:

• porolon
• PPU - Polyopoleretan.
• latex
• polystyrene balls

Output: Selecting the type of filler depends on the functional purpose of the sofa. For sleep, it is best to use sofas based on spring blocks or with latex filler. If you want to significantly save - thoroughly to help you, but then the sofa will have to change very quickly. The PPU occupies an average position. It will not work well and solving tasks - a sofa for sleep and for seating.

Upholstery There is a great set. Read the subtlety of the selection of sofas upholstery.

Fundamentally upholstery can be divided into

• natural (cotton, leather, tapestry, jacquard, silk)
• semi synthetic - consist of a combination of natural and synthetic fibers (flock, shenill)
• synthetic- consist entirely of artificial components (artificial leather)

But, I think among others constructive features Sofas Upholstery fabric plays the smallest meaning. Because it is easiest to replace it.

General conclusion in the upholsms: Look at them last more important design The sofa than its appearance. The use of the type of upholstery depends on the sofa destination.

Look at this sofa and think where it can be applied. After a short estimate, it turns out that there is not so much opportunities for its use.

You can find a design classification that is based on the types of premises in which the sofa will be used.

What result will get

• Sofa for the living room
• Sofa for the bedroom
• Sofa for kitchen, dining room
• Sofa for children
• Sofa in the hallway
• Sofa in the Cabinet or Library
• Sofa for loggia and balcony

It seems to me that such a division is not very true. Yes, it has the right to life, but the same sofa can be put into any of the rooms. The question is different. That would be done on this sofa - to sleep, eat or just sit. Do you understand what I mean? You can eat in the living room, and sleep in the kitchen.

Therefore, I would allocate everything three key groups of sofas for appointment

• Sofa for seating
• Sofa for sleep
• Sofa for seating and sleep

Conclusion for the purpose of the sofa: Look at those functions that the sofa will solve in your particular case and on the basis of this understanding choose. Don't throw on marketing tricks of sellers, such a sofa for the living room - buy it and you will be happy. And you want to eat and sleep on it and in this example, happiness will be, but the seller who "has been shifted" to you unnecessary sofa to you.

Video - types of sofas, to pay attention when choosing

Finally, I offer a small video clip. All I have already told the above again for consolidation. Only now "video language".

This is probably all. I hope my conclusions will help you.

Modern technologies help upgrade furniture attributes. Thanks to them, simple sofas are turned into a full-fledged bed, where it can accommodate from 4 to 8 people. In addition, the quality filler makes it absolutely safe for human health.

To date, several types of sofas mechanisms are known. Each of them has characteristic differences. It is distinguished here both positive and negative sides of this design.

Thanks to them, transformation allows you to save enough space. In our material you will learn what mechanism is better and what needs to be taken into account in the process of choice.

Varieties of folding mechanisms

Specialized departments have a huge selection of unfolding mechanisms for sofas. The most popular are considered:

• book;
• tango;
• euro book;
• pantograph;
• puma;
• elf;
• accordion;
• picky;
• french clamshell.

Book

The sofa book is considered a classic version of the furniture accessory. To transform it into a sleeping place, it is sufficient to lower the back back. In the decay process, it resembles the design of the book.

This mechanism has some advantages. These include:

• high-quality details;
• durable design;
• durability;
• spacious storage system.

The disadvantages of this building include:

• permanent movement of the sofa for transforming;
• fast deformation of the sleeping zone. The filler with time begins to deteriorate in the place of bend;
• narrow sleeping place. Only one person can fit here.

Tango

Sofa Tango, is a modernized model "Books". Modern designers Nicknamed this "Click-Klyak" folding mechanism. He has lateral and rear parts to transform. As a result, we get a full-fledged sleeping area where guests can be located.

The advantages of such structures are considered:

• three positions of the back back. Here you can adjust the angle of inclination, thereby selecting the desired position during the seating.;
• this sofa mechanism is suitable for daily sleep. Durable fittings in the structure, provides a secure assembly of all parts during operation;
• a large box that acts as a storage area.

In addition to the advantages, there are some drawbacks:

• it is not possible to set the sofa close to the wall surface;
• requires effort when transforming.

Eurobook

Sofa "Euro book". It is laid out by turning out the seat that has an additional roller system. The back is placed in the resulting plane.

Recently, this type of furniture attribute has won universal popularity.

The positive qualities of this building include:

• comfortable sleeping place;
• spacious storage system for bedding;
• durable fittings in the mechanism.

The negative qualities of this design include:

• deep seat. Without special additional pillows, it is impossible to relax here. The back is at right angles;
• the permanent movement of the front part will lead to the appearance of scratches on the floor surface.

Pantograph

Pantograph has some similarity with a modern "euro book." Transformation is made in a similar way. There are designs that provide movement forward and upstairs.

The positive qualities of this model are considered:

• uniform recreation area. In the process of laying the connection, the connection is practically not felt;
• light transformation;
• there is a place for storing various little things.

In addition, experienced specialists allocate the following flaws:

• uncomfortable seat. There is also available here deep landing. The body is under constant voltage. Additional pillows provide comfortable existence;
• complexity folding mechanism. As a result, its cost and maintenance increases.

Puma

The sofa "Puma" is a simple and convenient furniture accessory. It is neatly folded by one touch. In order to turn it into a sleeping area, it is enough to pull the seat. It is placed in the place of the resulting emptiness.

The mechanism of sofas "Tik-so" has a similar design with the "puma". It also easily turns into a comfortable resting place for two simple movements with hands. This model is ideal for a small-sized residential space.

It can be tightly suspended to the wall plane, thereby saving precious see. As a rule, soft texture fabrics are chosen for such a sofa. They help add a piece of comfort to the surrounding environment. In the photo of the mechanisms of sofas, components are captured, which are part of the folding structure.

Photo of sofas mechanisms

The sofa is an integral element of the interior of any apartment. At first glance, they are all the same. However, sofa laying mechanisms are radically different from each other. This question can play a decisive role in choosing one particular model. Therefore, it is important to understand in advance in this topic, and only then go for the purchase.

There are three main options. All of them are popular and regularly found on the furniture market. Allocate the following methods for folding and folding:

• Roll-out;
• Deployed;
• Folding.

Each of them has its own characteristics. Moreover, they are all divided into many species that differ in both the very folding and for the convenience of use. All these varieties need to know to choose the most suitable sofa for themselves.

Picky

This type is very easy to operate. It is only required to pull the loop on the front side of the sofa, after which it will roll forward. The tagging mechanism requires accuracy, but many years can be served with proper operation. A simple classic sofa of this type will give the owner of the comfort during sleep and comfort in the house achieved through compactness.

Eurobook

The Eurobook type is very convenient to use. Outdiction occurs very easily: the front part is extended, and the rear manually falls.

Benefits:

• Life time;
• Convenient folding process;
• Smooth surface;
• Interior box for things.

Large dimensions can be attributed to the disadvantages, because of which some people can feel discomfort when sitting. In most cases, EUROSOF becomes a good choice.

Pantograph

"Pantograph", which is also called "Tick So," represents all the same "eurobook", but has some improvements. When nominated, the front side of the sofa is not rolling on the floor, and is pulled out in the form of a small semicircle.

This type of layout allows you to avoid risk scratch flooring. A separate advantage is considered a smooth surface for sleep.

The third name of such a decay is "Butterfly".

Telescope

Such a mechanism is declined very quickly: it is enough to pull over the edge of the sofa, after which all its constituents alternately stretch in the same way as a telescope.

The telescopic sofa has its advantages:

• Height of the bed;
• Branch for linen;
• Compactness.

By cons can be considered a very big weight.

Conrad

The mechanism "Conrad" is identical to telescopic. However, it is characterized by greater sleeping height and increased convenience. When nominating elements, damage to the floor is excluded.

This is the most reliable mechanism, but its cost is completely unattractive.

Dolphin

IN last years "Dolphin" became popular. In the process of laying the movement of elements resemble a dolphin species. Often this type is used in angular sofas. You can also decompose it, pulling a loop.

• Suitable for daily use;
• Space area;
• Easy operation.

Notable minuses in such a design there.

Kangaroo

Such a transformation mechanism is almost identical to the previous one. The only difference is the enlarged height of the supports. Sofas with such laying allow you to extract the maximum comfort from sleep.

Pros and cons will reduce the height of the supports, which gives greater convenience, but reduces the level of reliability.

Ankar.

"Ankar" acts all by the same principle as the two previous ones. You need to pull the seat on yourself and pull out the block, stretching it up. It is highlighted in high reliability and space spacing.

Puma

Design retractable sofa "Puma" is very simple. You just need to pull the seat, after which it will deteriorate the base. "Puma" has high demand for the market, thanks to safety for sex and convenience.

Benefits:

• Silent folding / folding process;
• Easy use.

Corner models come with a special drawer for things that is on the back side.

Sedalift.

"Sedalift" is characterized by ease of use. It is ideal for sleep, but many models suffer from low strength. The instruction manual requires to roll out the lower part, decompose the folded tissue section over the extended base.

• Big sleeping place;
• Easy folding.

Of the minuses: the risk of scratching outdoor coating, as well as low suitability for regular sleep.

Deployable

All setting types are convenient, but this causes many special feelings. Cause in elegant appearance Faceted furniture. This kind is perfectly characterized by the word "clamshell". It is often used in the Russian names of subspecies.

In the decomposed state, the sofas remind a familiar to many clamshell. The sleeping place is kept on the supports and consists of a fairly thin material. It is formed from three elements. We just need to pull the edge of the seat so that the sofa transformer takes another look, and the two additional parts have become supported.

What are the sofas mechanisms - video:

This mount does not allow the sofa daily. It has reduced strength, as well as not very comfortable with long lying. As a rule, they are used only in the assembled form, and they are rarely unfolded.

French book

This is the main representative of such a mechanism. The French book is folded by stretching the main part, which leads to moving on the supports of the other two.

• Express decay.

• Unreliability;
• Overnight on the surface.

It is worth purchasing it only if it is extremely rare on it. In other cases, it is better to prefer the labeling mechanism forward.

Spartacus

This subspecies developed by the joint efforts of designers from Russia and Italy. it best mechanism For sleep from unfolding. It is a stronger French folding glass, reinforced with a metal grille.

• Strength;
• Convenience and suitability for daily sleep.

Of the minuses, only the fact that lifting mechanism Requires to remove pillows before placing.

Rich

This mechanism, also called the "American Book", is similar to the French option. You just need to pull the seat on yourself, after which everything will decompose. It differs in what consists of two blocks, and not three. At the same time, it has a thicker surface.

• High strength;
• Compactness.

He has another name - "Sedaflex". Of the minuses, only the lack of a lounge box.

As the previous version, the sofa of such a plan consists of two parts. The difference is that the transformation requires not to raise the seat, but move the back forward, turning the design so that the sofa relies on the legs.

• High reliability;
• The presence of springs.

• High price.

The spring mechanism allows you to remove maximum comfort from furniture.

Accordion

Another popular option reminds its principle of action, the musical instrument of the same name. The design is stretched in the same way as the scordon fur. Gradually, the sleeping place is stretched, leaning on the legs. Size it is similar to a large double bed.

• Compactness;
• Simplicity of lifting;
• Reliability;
• Department for things.

• Risk to damage the floor.

"Accordion" is very convenient to use and is characterized by acceptable cost.

Caravan

The mechanism is based on metallic frame. Especially pulling the seat up. At the same time, two platforms are drawn under the base. After folding, we compare the size with a large bed. You can collect a folding sofa very quickly.

Pluses in durability and simplicity. Minus only in the absence of a lounge box.

Ribalto

The popular version of the folding "Ribalto" is distinguished by a thoughtful design. It attracts attention to its simplicity and convenience. The process of folding such a sofa is simple: you need to lower the back to the seat, then turn them over, putting it on the floor. So the bed is formed. There are models with automatic laying.

• Fast and simple folding;
• Spacious.

Significant minuses in the mechanism do not allocate. Also called "slider" in the angular version.

Unlocking sofas

Modern layout mechanisms include the third type - folding. He is familiar to everyone who had an ordinary inexpensive sofa. The main advantage is the presence of a large-size liner.

Tango

Such a sofa is very functional, since it is capable of making several provisions. It has a similarity with a book. You need to pull the lower part, after which the back drops.

• Intermediate layout options;
• Smooth sleeping surface.

Of the minuses, only the inability to put the sofa close to the wall. There is also an option "Adventor" with a retractable footrest.

Butterfly

The "Butterfly" combines the retractable and unfolding mechanisms. Allows you to quickly fold and collect sofa. First, the bottom is pulled out, then the upper back is drawn back.

• The speed of the mechanism;
• Bed size.

By cons of the sofa of such a form can be attributed to damaging the rollers used when rolling. By the folding method, the mechanism is very similar to the eurobook.

Book

Classic for most people mechanism - book. Eliminate and fold the sofa book is very simple. You need to leake back back, after which it drops, increasing the area for sleep. It consists of such a sofa from a metal or wooden frame.

Parameters allow you to fit inside the section for a large liner. Also, the advantages include strength, simplicity and low cost.

Domino

The mechanism called "Domino" combines rolling, Eurobook and Dolphin. The lower part is drawn, the back is folded and the diving is lowered down, forming a place to sleep. The sofa characteristic does not allow to include a department in the design for things that makes the mechanism less attractive.

The main plus of such a triple design is to the height of the bed.

Conclusion - Final selection
