Sofa transformation mechanisms - which one is better to choose? Sofa designs: their features, advantages and disadvantages Types of sofa decomposition.

A folding beautiful sofa is not just a piece of furniture in the living room. This is a multifunctional device that allows you to solve various problems and compensate for the lack of space in the room. But how many realize that choosing a sofa is far from being such an easy step as it seems?

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

But here the question immediately arises: how to choose a sofa in your apartment so that it fits well into the interior and reliably serves for many years without turning into an instrument of night torture. After all, as we remember, it will have to be laid out and folded at least twice a day. In other words, you need to find out which mechanisms have proven to be the most reliable, and which, on the contrary, are unsuitable for frequent unfolding. And what are the general advantages and disadvantages of sofas of one type or another? To date, the furniture range is represented by a huge selection of sofas with a variety of types of transformation. And each model has its pros and cons.

Let's consider them all.

1. Elf is the simplest and most unpretentious type of sofa.

   
   

   It unfolds by simply lowering the sidewalls-armrests, which can be fixed in a comfortable lying position. This opportunity to sit in a reclining position creates an orthopedic effect. This sofa is very compact, although it is designed for only one person. In addition to this, it has a box for bedding.

2. Sofa book is clear from the name that this view is transformed by analogy with the opening of the book.

   
   

   To turn it into a place to relax, you need to raise the seat. The back will go down, taking a horizontal position. Then the seat is lowered back. Transformation mechanisms of this type are considered the most enduring of all existing ones. In addition, these models have a drawer for bedding at the bottom. But they also have certain disadvantages. Due to the peculiarities of the transformation, they cannot be moved close to the wall. In addition, when unfolded, they are not very spacious. But the most unpleasant thing is that in the place where the back and seat are joined, a gap forms over time, which interferes with comfortable sleep.

3. Eurobook sofa. Despite the similarity in name with the previous type, this model is laid out differently. The seat slides out or rolls forward, and the soft backrest overturns into the vacant space.

   
   

   The result is a very spacious seating area with a box for bedding below. Features of the design allow you to tightly push it to the wall. And the simplicity of the mechanism makes it more durable than the model of the previous type. However, when folded, such sofas are uncomfortable: their seat is too wide, so leaning back is not very comfortable.

4. Sofa with Tango mechanism (click-clack)

   Tango (click-clack) is a stylish sofa, which is an improved version of the "book".

   
   

   It unfolds according to the same principle: the seat rises, lowering the back, and then falls back. A notable feature of this type is the convenient folding sidewalls, which can be lowered to increase the area of ​​​​the bed or raised to make armrests. Another feature of this sofa is the ability to transform the back into a semi-unfolded state. Despite the apparent complexity, the mechanism of this sofa is also durable. Plus, there is a storage compartment at the bottom. However, like the "book", it cannot be moved close to the wall.

5. Pantograph - this type of sofa unfolds according to a principle similar to the Eurobook, except that in order to extend the seat it must be lifted up and then moved forward.

   
   

   After that, the backrest also overturns into the vacant seat. Thanks to this design, it retains its advantages in surface area, however, when folded, it is still not very convenient on it. Such a mechanism, although it provides ease of transformation, as well as an absolutely flat surface of the place to rest, significantly increases the cost of the model. But there is a box for bedding.

6. Puma - similar to the previous type of mechanism, this one unfolds according to the principle of raising and extending the seat of the sofa.

   
   

   At the same time, a soft platform rises to the vacated space from below, creating a single place for sleeping and relaxing. Such models are advantageous for easy unfolding, but, as a rule, they do not have a box for bedding. In addition, the backs of such models are separate pillows, which, in the mode of a place to sleep, always have nowhere to put them. Most often, this type of mechanism is on corner sofas.

7. The accordion is perhaps the most versatile model. It unfolds according to the “accordion” principle by extending the seat, which drags along and unfolds the back folded in half.

   
   

   The result is a spacious sleeping area. Whereas when folded it is very compact. But such an advantage also translates into a significant drawback: a lot of space is needed for an unfolded sofa, which will be fatal for a small room. In addition, such a mechanism requires considerable effort.

8. French folding bed - this option is hardly suitable for everyday use, but as an additional guest place it is quite suitable.

   
   

   The back of this model is usually replaced by pillows, which are removed before transformation. After that, the seat sequentially unfolds into three sections (according to the clamshell principle), forming a roomy place to relax. This type of mechanism is not reliable. In addition, there are uncomfortable gaps between the unfolded sections that interfere with comfortable rest. In addition, there is no laundry box.

9. American clamshell - unlike the "French" counterpart, this type of mechanism is more reliable and will withstand frequent transformations. It unfolds a little differently.

   
   

   First, a block with a folded component is pulled out of the sofa body. The seat of the pull-out unit rises, and the composite section unfolds forward like a clamshell and is installed on the legs. It turns out a spacious bed. However, not very comfortable seams remain between the sections. In addition, there is no compartment for linen.

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

    
    

    After that, a sofa block is lifted from the body, which, in turn, is decomposed into two more sections, which are installed on the legs. All sections are made of durable metal, which significantly reduces the weight of the structure in comparison with standard elements of other types of sofas. However, this design makes it impossible for the sofa to store bedding below.

11. Roll-out - another type of mechanism, characterized by both simplicity and reliability.

    
    

    At the heart of its transformation is a retractable front part, on which there is a pillow folded in half. This pillow unfolds and fits into the vacant space. A spacious, and most importantly, a sleeping place without seams is formed. However, the height from the floor of such a sofa may seem too small to someone.

12. Outdoor - perhaps the simplest and most economical type of sofa.

    
    

    The folding part, consisting of two parts, when folded, fits completely into the body of the sofa, forming its seat. Whereas, when unfolding, it is placed on the floor without legs or supports. The design is simple and therefore reliable. But, of course, there can be no question of any box for linen.

13. Konrad - a model with a three-section mechanism. When assembled, this is a beautiful and stylish sofa, and when disassembled, it is a spacious place to sleep.

    
    

    It is transformed by pulling out the seat, from which, in turn, the third section with the lifting part extends. As a result, a place to relax is not only large in area, but also high. The mechanism of this model, although reliable, is quite heavy. But there are boxes for storing bedding.

14. Dolphin - a similar type of transformation is most often found in corner sofas. The principle of its operation is the extension of the lower section of the long side, followed by lifting the pillow up with a soft handle.

    
    

    As a rule, a corner sofa of this design has a backrest consisting of individual pillows. Pillows have to be removed when unfolding the bed. The mechanism is resistant to loads, but wears out rather quickly. In addition, a carpet laid on the floor will greatly complicate the extension of the section.

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

    
    

    However, this design loses its reliability. And, like models with the dolphin transformation type, this sofa does not have a long service life.

16. Recliner is the most modern and progressive kind of transformation mechanism. It allows you to adjust the position of the individual parts of the sofa - backrest, armrests, footrest, etc., thus creating the perfect place for relaxation.

    
    

    On some more expensive models of such sofas, vibration massagers are installed, which are controlled using the control panel. In addition, the appearance of such sofas is the most solid and presentable. However, they also have significant drawbacks. A full bed on such a sofa is unlikely to work. And the cost of even the simplest models bites.

The choice, as we see, is huge. So a sofa with which transformation mechanism to prefer? The first thing to consider is the size of the family. For one person, a sofa with an “elf” mechanism or some kind of “book” will suffice. Singles who are not constrained in their means and who want to stylishly and tastefully furnish, for example, a studio, can spend money on a recliner sofa. If the family is very large, then the best option would be roomy sofas when folded - for example, corner ones. For a small family, sofas of any other types are suitable for spaciousness.

To save space, it is also worth focusing on models that, both folded and unfolded, do not take up much space. Also, preference can be given to models with a lifting mechanism for storing bedding - space for blankets, pillows and blankets will not be superfluous. This option is especially relevant for sofas with pillow backs. It is not worth dwelling on options with unreliable mechanisms. They won't live up to your expectations. Those who are accustomed to sleeping on a perfectly flat surface of the bed should also avoid folding sofas and other varieties in which irregularities form between the pillows over time.

Otherwise, the results of the choice will focus on the preferences of the person. After all, as it usually happens: you go to a store or to a website, you see a sofa and you understand that it is what you need. And all these mechanisms, advantages and disadvantages fade into the background.

When buying a sofa for home or summer cottage, special attention should be paid to the device of its transformation. The organization of the sleeping space and the durability of the model depend on it. Today, the mechanisms for transforming sofas are very diverse. They are designed taking into account the area of ​​\u200b\u200bthe premises, often they easily turn a sofa into a bed. Even a teenager can handle them. In order not to get 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 by type of transformation

Three types of sofas can be distinguished, in which special transformation mechanisms are used. They may be located:

• In direct models- representing a familiar design from the main part with or without armrests, having a linen box (and in some versions - a box in which the sleeping block is located).

• In corner structures- with a corner element that has its own functionality in the form of a niche, a spacious box for bed linen or other things. It saves space in your closet.

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

The sofa owes its name to the mechanism of transformation. Although companies come up with an interesting name for each model, the basis of the name that characterizes a particular model is precisely the principle of its mechanism.

The operation of the device does not change - regardless of the type of model (straight, modular or angular). The sofa unfolds forward, sometimes at the same time it rises up, rolls out, extends, turns. If this is a straight view, the base is transformed, in the corner version the sleeping block is added to the corner, forming a rectangular seating area. In modular constructions, the direct part of one module is transformed without affecting others.

The work of any mechanism is not as complicated as it might seem at first glance. The principle of operation of structures is different and has both pluses and minuses. Most of them can fit all types of sofas (straight, corner, modular). For them, the presence or absence of armrests of the model does not matter. However, there are transformation systems that fit only one species.

Sliding and withdrawable

Roll-out forward models are convenient, they are compact when folded, do not take up much space, do not create the impression of a cluttered room. The principle of their work is to roll out the block forward and raise it to the desired height. Sliding structures are models whose details are interdependent, so when transforming one, the other is automatically activated.

"Dolphin"

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

To expand the model, you need to pull the loop of the box located under the seat, in which the missing section of the bed is located. When the block is extended to the stop, it is lifted by the loop, put in the desired position at the level of the seat. This design forms a spacious and comfortable surface for sleeping, withstands a large weight load.

"Venice"

The principle of operation of the roll-out mechanism resembles the Dolphin. First you need to push the section located under the sofa seat all the way towards you. By driving the transformation device, extend the seat unit, increasing the width of the sleeping bed. After rolling out the block to the stop, it is raised to the height of the seat with the help of loops.

Such designs are convenient. They are often found in corner models, have a lot of free space in the corner elements.

"Eurobook"

An improved "book" is a great option for daily use. It is equipped with a reliable and easy-to-use transformation mechanism that is resistant to daily stress and allows you to place the sofa in the center of the room or against the wall.

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

"Conrad"

The device, which some manufacturers call "Telescope" or "Telescopic", is a withdrawable model. To make a bed out of such a sofa, you need to pull out the section under the seat, raise the base, then put the pillows in the drawer, close the base and place the mats on it, unfolding them like a book.

The design is convenient and allows you to organize a spacious bed without moving the sofa away from the wall. The floor surface must be flat, as for all withdrawable mechanisms, therefore, a carpet laid on the floor may cause the transformation system to fail.

"Pantograph"

The design, known as "tic-tac" - a variant with a walking mechanism. It is an improved version of the Eurobook. To transform, you need to pull the seat forward with the help of the hinges, lifting it up. At the same time, it will itself take the necessary position, dropping down. It remains to lower the back, forming a spacious sleeping place for two.

In some models, the manufacturer has provided additional armrests that limit the seating area. Such a device is durable and does not loosen the body of the model. However, options with a soft back are not very comfortable. To expand such a sofa, it will have to be slightly moved away from the wall.

"Puma"

This model is a kind of "pantograph" - with a slight difference. As a rule, these sofas have a low and fixed back, so such models can be placed against the wall, thereby saving usable floor space.

The transformation is carried out by one extension of the seat - unlike the previous mechanism. When it rises and, falling, falls into place, at the same time, the second block of the sleeping section rises from below (where the seat used to be). Once the seat is in place, the two blocks form a complete sleeping bed.

"Saber"

Convenient roll-out mechanism "saber" provides for changing the size of the sleeping bed with full or partial unfolding. This design is distinguished by a linen box, a high place to sleep.

Sleeper furniture can consist of two or three sections - depending on the model. To expand it, in any case, you need to roll out the seat, under which the linen box is located, forward. At the same time, the backrest leans back, fitting into the desired position.

"Goose"

The original roll-out transformation system, for which you must first roll out the bed block from under the seat, and then raise it to the level of the seat. At the same time, due to the peculiarities of the pillows rising on the back of the structure, there is an increase in the sleeping bed.

Assembly and disassembly of such structures take more time than other systems.

This model is quite complex and not suitable for daily use. But when folded, models with this system are very compact, they look neat, so they can be purchased as upholstered furniture for a summer residence or a living room.

"Butterfly"

Sofas-transformers with the "butterfly" system are considered one of the most reliable, durable and durable. Today, such a system is very popular among buyers. She turns a sofa into a bed in just a few seconds. The transformation is carried out in two stages: the seat is rolled out forward, then the upper block is folded back (to the extended rear section).

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

"Kangaroo"

The kangaroo transformation mechanism resembles the dolphin system - with a slight difference: abrupt movements similar to kangaroo jumps. It has a lower part, located under the seat, which, when unfolded, easily slides forward. The retractable block rises to the right place, firmly in contact with the main mats.

The main thing that distinguishes such a mechanism is the presence of high metal or wooden legs. The disadvantages of the system include a short service life with frequent transformation. This design cannot be called reliable.

"Hesse"

The device of this mechanism resembles the "dolphin" system. To expand such a sofa, you will first need to pull the loop of the lower section under the seat, pull it out until it stops. The seat will also roll out. Then the block is raised to the level of the height of the berth, the seat mat is lowered back, forming a full-fledged sleeping bed in three parts.

This system is used in straight and corner sofa models. However, it also has its drawbacks, because with the constant rolling out of the block, a large load is created on the frame of the sofa. In addition, if you do not take care of the rollers, the mechanism will have to be repaired after a while.

folding

Mechanisms with unfolding sections are no more complicated than roll-out ones. Usually they are based on the most versatile systems (“frog”), so they do not require more than a few seconds to turn the sofa into a full-fledged bed. For their transformation, it is not necessary to roll out sections from under the seat.

"Click Clack"

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

To expand the sofa, you need to raise the seat until it clicks. At the same time, the back is lowered back, the seat is slightly pushed forward, revealing the two halves of the block into a single surface for sleeping.

"Book"

The simplest transformation mechanism, reminiscent of opening a book. To make the sofa look like a bed, you need to raise the seat, lowering the back. When the back begins to fall, the seat is pushed forward.

"Scissors"

The corner sofa transformation mechanism, the principle of which is to rotate one section to another - with the unfolding of blocks and reliable fixation of the sections with a metal fastener from below. In this case, a compact sleeping bed is formed with a bedside cabinet, open as a result of the transformation of the sections.

"Caravan"

The design, the unfolding of which is similar to the Eurobook system, however, it has a fixed back, and instead of two sections of the sleeping bed, three are laid out. At the same time, the seat is also raised and simultaneously pulled forward, then lowered to the desired position on the floor. At this time, the next one moves out from under each block, folding together into a single area for sleeping. Comfortable design with a spacious seating area. In some designs, instead of the third section, a folding pillow is used, which stands in front of a fixed back.

Daytona

System with folding fixed cushions that act as a backrest. The device of the mechanism is a bit like a "clamshell". To transform the sofa into a bed, you need to raise the pillows to the top position, then put the lower ones in the allotted places, grab the handle and turn the seat unit down, revealing a two- or three-piece sleeping bed. When the sleeping place decomposes, you will need to lower the pillows, wrapping them on the bed.

"Tornado"

Folding mechanism designed for daily use. The design is based on a double-folding "folding bed", which is hidden in the usual position of the sofa. It transforms without removing the seat, after tilting the back of the model. The design is convenient, it is not very difficult to disassemble, it has steel elements and mesh at the base, as well as mats of moderate rigidity.

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, reminiscent of stretching accordion furs. To expand such a sofa, you just need to pull the seat. At the same time, the backrest, consisting of two blocks connected from above, will automatically fall down, unfolding into two halves.

"Belgian cot"

This design is similar to a "cot" hidden under the sofa's modular seat mats. Even externally, the system resembles a familiar piece of furniture with metal supports. The only thing that makes it different is that it is fixed at the base of the sofa and unfolds right out of it, turning the seat unit down

"French cot"

An alternative to the "accordion" system - with the difference that in the latter the bed is made up of three blocks (according to the principle of folding a fan), and in this system the blocks are wrapped inward and unfold when unfolded. They are equipped with stands and have a narrow type of packing, which is a disadvantage of such designs.

If you are going to expand the sofa, you need to remove the modular pillows from the seat.

"American cot" ("Sedaflex")

Such a mechanism is more reliable than its French counterpart. It is not necessary to remove the cushions from the seat before transformation. The system implies identical sections (there are three of them), which are laid out one after another when the seat is raised. Such a mechanism is quite durable, but it is only suitable as a guest option, because it has thin mattresses, there is no compartment for linen and steel structural elements are felt at the joints of the sections.

"Spartacus"

A variant with a clamshell mechanism. The folding structure is located under the seat, consisting of modular cushions. In order for the sofa to become a bed, you need to remove the pillows, freeing the clamshell blocks. Since they are in the wrapped position, they first take the top one, set the desired position by exposing the metal support, and then unfold the remaining sections. This design is not designed for daily transformation - like analogues.

with swivel mechanism

Models with a rotary mechanism differ from other systems in ease of transformation. In them, the load on the frame is minimal, since there is no need to roll out the sections to the stop. They do not need to lift additional blocks.

Both the integral part of the sofa and the component of each block can turn, depending on the model. Such a mechanism is used in corner models, connecting the two halves of the sections with blocks into a single bed. The principle of operation of the system is based on turning half of the block by 90 degrees and rolling it to the other part of the sofa (with subsequent fixation).

With folding armrests

Folding armrests - a unique technique of the transformation mechanism. Today, such sofas are in the center of attention of designers. With their help, you can furnish the children's room, if necessary, adjusting the dimensions of the furniture.

"Lit"

A peculiar design that allows you to change the size of 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 the positions can be different. To transform the sofa into a single bed, you must first lift the armrest inward until it stops, and then bend it outward. These designs are designed for direct varieties of sofas, they are bought for children and teenagers.

"Elf"

A system convenient for small-sized rooms and children's rooms, a large area for transformation is not needed. Furniture can be placed against the wall. This sofa can be compared with its counterpart, it has a compact body and ample space for storing bedding. The seat surface and armrests form a single unit that folds out in length.

With advertisers

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

Double and triple folding systems

The mechanisms of transformation may vary. As a rule, the more complex the mechanism, the more components of the bed (the number of additions). Folding and pull-out sofas fall into this category.

Which one is better for daily sleep?

When choosing a sofa for daily use, you need to pay attention to designs in which the load on the frame during the operation of the mechanism is most uniform and does not loosen the body.

It is necessary to choose the right not only the mechanism, but also the degree of rigidity of the backrest, seat. You also need to choose a good upholstery material and pay attention to models with the ability to change covers.

Filling blocks

When choosing a sofa for daily sleep, it is worth considering the block filler. It is of two types: spring and springless.

The first packing options are distinguished by the presence of twisted springs (the position is vertical). We can distinguish between dependent and independent types. In the first case, the sofa bends down. Such mats are unreliable in that they do not have proper support for the spine during rest or sleep (sitting and lying down).

Independent type springs do not touch each other, so each of them works independently, without forcing others to sag where they do not need to. As a result, the back always remains flat, and the load on the spine is reduced.

Springless mats have a remarkable orthopedic effect, this is the prevention of problems associated with the spine. They are not only safe, but also very comfortable, provide a complete and proper rest during sleep.

This type of filler is hypoallergenic, this stuffing is not subject to the formation of fungus, mold. It is resistant to dust accumulation, because there are no significant voids. The best springless fillers include natural or artificial latex, coir (coconut fiber), polyurethane foam type HR.

What's better?

In order for the sofa to serve for a long time, it is better to choose a quality type of filler: a block with independent springs, latex or coir. It is very good if the type of mat is combined - when not only the core of the stuffing is added, but also other material (to give the desired rigidity).

If a latex block doesn't fit the budget, look into HR-type furniture polyurethane foam or synthetic latex. These materials are somewhat inferior to expensive packings, but with proper operation they will last for 10-12 years.

As for the transformation mechanism, “dolphin” designs and their analogues, models with a “clamshell” system, are not suitable for daily use. The most reliable designs for every day are "Eurobook", "Pantograph", "Puma" and rotary mechanisms.

How to choose the right mechanism?

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

• designated space for the sofa (folded and disassembled);
• the purpose of the sofa (guest option or alternative to the bed);
• load intensity mode (weight control, taking into account the choice of the “correct” seat and back blocks);
• simplicity and ease of use (the sofa should be light, because complex systems break down more often and cannot always be restored);
• the correct diameter of the steel elements (at least 1.5 cm).

In order for the purchase to be successful, the sofa lasted for a long time, you should pay attention to:

• flawless course of the mechanism in operation (it should not jam);
• lack of looseness of the structure during transformation (this is an obvious marriage that reduces the life of the sofa);
• absence of rust, scratches, dents, mechanism assembly defects;
• high-quality upholstery material that will not wear off from the frequent transformation of the sofa (when the sections come into contact);
• strong and durable metal of the mechanism, resistant to heavy weight loads (two or three people);
• the reliability of the frame components to which the transformation mechanism is attached.

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

Modern sofas do a good job of organizing a bed. Thanks to such an option as transformation, you can save space in the living room and provide comfortable conditions for sleeping.

Manufacturers offer many design options for upholstered furniture and various folding sofa mechanisms. Which one is better for every day? - this is the most important question with such a large assortment.

Which sofa mechanism is better for daily use (sleep), and which option to choose if the sofa is intended for the living room and will rarely be laid out? To make the right decision, we recommend that you familiarize yourself with the features of existing transformational mechanisms.

Folding sofa models have gained well-deserved popularity. Monolithic options (without a transformation mechanism) exist and can also be installed in a living space, for example, in a kitchen or hallway, but they are less functional.

If you are focused specifically on a folding sofa, then which mechanism is better to choose will be the envy of several factors. What matters is how often you plan to use it for sleep, how many square meters in the room are available for this piece of furniture and what operating period you are targeting.

Classic sofa bed. To organize a surface for sleeping, you should raise the seat, while the back will take a horizontal position. Now you need to return the seat to its original position - the "book" has opened.

Pros:

• durable and simple mechanism, it is almost impossible to break it;
• takes up little space and is suitable for small rooms;
• there is a compartment for bed linen.

• the body can be moved as close as possible to the wall, only if it will not be transformed daily into a sleeping place. The sofa can be moved apart only if there is free space behind it;
• in the area of ​​\u200b\u200bcontact between the back and the seat, a tubercle or depression may occur over time, this reduces the comfort of the bed;
• a compact (perhaps cramped for some) sleeping surface.

Important! The “book” mechanism has an elementary device, but in order to expand the sofa, force is often required. Therefore, it will not be entirely comfortable with constant use for a woman or child.

Tango

A modernized and more comfortable variation of the "book" mechanism. Some manufacturers stick to the name "click-clack".

• the backrest, in addition to the vertical and horizontal position, can be fixed at an angle and create conditions for comfortable rest (reclining);
• the mechanism is simple and adapted for regular use;
• there is a spacious box for storing bed linen.

• it will not be possible to install the sofa close to the wall, free space is required to recline the back;
• efforts must be made to transform.

The body can be moved as close as possible to the wall, the transformation is different than the standard "book". The seat extends (rolls out on rollers), creating an empty area that is equal to the height of the backrest. The backrest fits into the space that has arisen and a sleeping place is obtained.

• the sofa is easily converted into a comfortable bed, the sleeping surface is spacious;
• the system is durable and easily withstands regular use;
• internal niches for storage of linen are provided.

• a sufficiently deep seat, most often it is possible to lean on the back only by climbing onto the seat with legs or using additional sofa cushions;
• if there are no rollers on the exit part, the floor may be scratched.

Interesting fact! Every year they become more and more popular. All models work using a single mechanism, but there are differences in design. You can purchase a sofa without armrests, with only one or with two on the sides. There are also differences in size. For example, you can choose:

Pantograph

This mechanism is arranged by analogy with the Eurobook. To prepare the area for sleeping, you need to pull the seat up. At this point, a mechanism is activated that will move the seat up and forward, and then extend the support elements. The back is placed in the resulting empty zone.

• a wide monolithic and even surface for sleeping (the joints are not felt);

Folding models of upholstered furniture have practically ousted other options from the market. Their versatility and practicality form a steady consumer demand. Responsible for these characteristics are the mechanisms for transforming sofas, which are being improved every year thanks to the innovative developments of specialists. Modern upholstered furniture has become more reliable and durable. And now a fragile woman and a child can turn it into a full-fledged sleeping place without any problems.

Purpose

Folding sofas are necessary to save usable space in the room. They can be used as the main bed, and the universal model will help out if guests arrive. During the day, such furniture is usually in a folded position and performs its direct functions.

The design, dimensions and folding mechanism determine the function of the sofa in the interior. For example, "Click-clack" requires more space against the wall, and "Tango" will take over the functions of the main bed in the nursery.

You can count several dozen modern mechanisms for transforming sofas. Each of them has its own design features and advantages. At the same time, the basic device of any sofa is approximately the same. Upholstered furniture consists of several basic elements:

• back;
• seat;
• armrests;
• frame;
• filler;
• upholstery.

In addition, it can be additionally equipped with pillows or drawers for storing bed linen and other things. The transformation device is a set of parts that includes a articulated lever mechanism, guides and rollers. Its main task is to increase the area of ​​\u200b\u200bthe bed. Usually the design is placed in the back and middle blocks of the sofa.

Overview of popular models

All types of sofas differ in several ways. By design, they can be angular, straight, modular. By the number of places - double, triple and more. Also, the furniture is equipped with a different mechanism for laying out sofas.

Depending on these criteria, products differ:

• dimensions;
• convenience;
• bed size;
• design.

Having studied the design features and clearly knowing your own needs, you can make a smart choice. First of all, it is necessary to take into account the regularity of operation - whether the furniture will be laid out daily or from time to time. In the first case, the most reliable mechanism is needed. And in the second, the main thing is that the furniture fits into the interior when folded.

Books

The most common type of upholstered furniture. By design, products can vary significantly, but the basic principle remains the same - the design of the sofa allows you to fold and unfold it like a book. The furniture consists of two halves moving relative to each other, which provide for two or three positions. To fix the sofa in any of them, just pull one of the parts towards you.

There are several types of this mechanism:

1. The usual "book" is the oldest of the existing models. Identical furniture options were still sold in Soviet stores. They have only two fixed positions and a simple transformation mechanism. This model is budget friendly. Inexpensive fabrics are used for upholstery, chipboards are used as a frame. The main drawback is the insufficiently even and spacious surface for sleeping. In addition, a similar mechanism for a sofa implies that the product will have to be constantly moved away from the wall. This is quite difficult, given that ordinary "books" are often equipped with storage boxes.
2. "Eurobook" differs from the usual "book" in that it does not need to be moved away from the wall. The folding mechanism allows you to roll out the front part, then the back fits into the resulting opening. The furniture is characterized by more impressive dimensions, it can comfortably accommodate two people. The sofa with the Eurobook mechanism can be used as a comfortable bed for one person, even when folded. The cost of such furniture is much higher than that of the previous model.
3. "Tango" ("click-clack") - options that are comfortable for sleeping, the main feature of which is the absence of a pronounced joint between the two halves of the "book". The furniture looks like a single whole, both folded and unfolded. The model is often equipped with armrests, which, when unfolded, can be lowered and raised at an angle in the form of a headrest. These types of sofas are often used as beds, that is, they are not folded in the morning.
4. Pantographs are the most complex mechanisms of "book" type sofas. There are several varieties of them. You can unfold the "Puma" sofa in one motion, without using rollers (which means that it is impossible to spoil the floor). The seat is pushed forward, the backrest is lowered, at the same time the legs of the support are lowered. You can fold everything back with the help of special handles. The pendulum device underlying the "walking eurobook" allows furniture to be transformed by simply pulling on the loop. To unfold the model with the tick-tock mechanism, it is enough to pull the seat towards you and slightly up and gently lower the structure to the floor.

Among the advantages of models equipped with a "pantograph" is the smoothest movement of the mechanism among the "books".

Roll-out structures

The roll-out mechanism means the presence of wheels. Part of the structure - two segments - in the folded state is inside the sofa. In order to spread out the furniture, it is necessary to roll out this half from the body, and then raise it flush with the seat. The quality of the videos is key.

Clamshells

The transformation of any "clamshell" occurs according to the principle of familiar furniture of the same name. The "French folding bed" in the unfolded state looks a bit like the Soviet model. You just need to stretch three sections forward, and it will stand on the metal supports hidden in the body. This is a lightweight, but quickly wearing mechanism, which can be mechanically damaged if the weight of the sleepers is too large.

Some of the problems were solved in the "American clamshell" model (sedaflex). It differs from the French one in that the transformer mechanism does not stretch out, namely, it unfolds according to the principle of a sandwich. First one section folds out, then another. Between them are supports. When installing sections on supports, a berth is obtained. This is one of the most convenient and reliable mechanisms for transforming sofas.

The main drawback of the "American clamshell" is the lack of a storage system. Inside the sofa is only a bed.

Accordion

In a way, this is also a clamshell. But if the latest types of transformation mechanisms hide additional sections at the bottom of a piece of furniture, then the “accordion” is in the back, which consists of two sections. For unfolding, it is necessary to push the lower part forward, and the back will decompose.

When folded, the "accordion" looks attractive and compact. And the absence of a mechanism at the bottom makes the sofa more reliable. Drawers for linen are not provided in the model, so it is often equipped with additional cabinets. The sleeping surface is flat, but its size is limited by the height of the back. Another significant drawback is the possibility of damage to the flooring during the transformation process.

Sofas equipped with a mechanism such as "accordion" are not very popular, so you won't be able to immediately find a model of a suitable color and size.

Folding sofas with metal frame

Models on a metal frame are more difficult to manufacture, more expensive. But if all the connecting nodes and mechanisms fit exactly, such sofas can last longer. The frame is based on shaped pipes, and cushions are placed on a metal mesh up to 0.5 cm thick. Due to the increased strength, such a frame is the most reliable for daily use.

Spartacus

"Spartak" is equipped with a mechanism that unfolds forward. The triple folding device is somewhat reminiscent of the "American clamshell", that is, it unfolds in three stages, standing on the supports inside the frame. An additional advantage is the presence of a polyurethane foam mattress and a metal mesh base, guaranteeing a comfortable sleep. Such elements are recommended by orthopedists for people who have problems with the musculoskeletal system.

In the Spartak models, not just a reliable transformation mechanism, such sofas are designed taking into account medical recommendations.

Elf

Sofas "Elf" with a metal frame have an orthopedic effect. An additional plus - models with a stepper mechanism increase the usable area of ​​\u200b\u200bthe bed due to the sections located at the bottom of the piece of furniture or in the back. And the "Elf" is laid out due to the armrests. They are bred on the sides - the design becomes longer. The frame is made of profiled pipes. The base for the pillows are curved wooden transverse slats.

The most complex and functional products

Sophisticated models of folding sofas are equipped with universal mechanisms and electronics that allow you to give the sleeping position the most comfortable position for a particular person. Among all types of folding furniture according to the type of transformation, the most multifunctional can be called the modification options "recliner". They are equipped with a control panel that allows you to fix the footrest at the desired angle, push it only a certain distance. The backrest angle is also adjustable. Recliners are supplied with vibration massagers. Smart models with electronics can remember settings. The disadvantages of recliners are obvious. They are expensive, in the event of a breakdown, repairs will also cost a round sum. In addition, this is more of a place to relax, not to sleep - there is no full-fledged sleeping surface.

Even a superficial acquaintance with what the sofa folding mechanisms are like leads to the conclusion that there are no universal tips for choosing. It all depends on many factors:

• housing conditions;
• frequency of use;
• financial opportunities;
• the required sleeping area.

It is definitely impossible to answer which sofa mechanism is better. Each has certain advantages and disadvantages. Simplicity of design can be a plus when it comes to constantly using an inexpensive mechanism. And a disadvantage if the main criterion is the comfort for sleep.

Expensive models equipped with an electric drive and a vibration massager will help you relax after a working day. But sleeping on them is hardly more comfortable than on a regular "book", which is much cheaper. In addition, the simple mechanism of the sofa is the most reliable, because there is nothing to break.

For regular sleep, it is better to choose a reliable and comfortable model of upholstered furniture. As a guest sofa, you can use a design that occupies a minimum of usable space.

In the store, you need to check the serviceability of the transformation mechanism. It should not make extraneous sounds or jam. To determine the quality of the assembly, you need to try to expand and fold the furniture several times.

Before giving preference to a particular model, it is worth deciding how exactly it will be used, prioritizing. Only then will it be possible to make an informed and reasonable choice. A wide range will allow you to purchase a product that meets all requirements.

The choice of sofa depends on living conditions and the frequency of use of the product.
