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

There are three main layout options. All of them are popular and are regularly found in the furniture market. There are the following ways of folding and unfolding:

• Withdrawable;
• deployable;
• Folding.

Each of them has its own characteristics. Moreover, all of them are divided into many types, differing both in folding itself and in ease of use. All these varieties you need to know in order to choose the most suitable sofa for yourself.

Withdrawable

This type is very easy to use. All you need to do is pull the loop on the front of the sofa, after which it will roll forward. The roll-out mechanism requires accuracy, but with proper operation it can last for many years. A simple classic sofa of this kind will give the owner comfort during sleep and coziness in the house, achieved due to its compactness.

Eurobook

The Eurobook type is very convenient to use. Unfolding is very easy: the front extends and the rear manually lowers.

Advantages:

• Life time;
• Convenient folding process;
• Smooth surface;
• Inner storage box.

The disadvantages include large dimensions, due to which some people may feel discomfort when sitting. In most cases, "Eurosophy" becomes a good choice.

Pantograph

"Pantograph", which is also called "Tik Tak", is still the same "Eurobook", but has some improvements. When pulled out, the front side of the sofa does not roll on the floor, but is pulled out in the form of a small semicircle.

This type of layout avoids the risk of scratching the flooring. A separate advantage is considered a flat surface for sleeping.

The third name for this unfolding is “butterfly”.

Telescope

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

The telescopic sofa has its advantages:

• Sleeping height;
• Linen compartment;
• Compactness.

The disadvantages include a very large weight.

Conrad

The "konrad" mechanism is identical to the telescopic one. However, it is characterized by a higher bed height and increased convenience. When extending the elements, damage to the floor is excluded.

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

Dolphin

In recent years, the "dolphin" has become popular. In the process of unfolding, the movements of the elements resemble a dolphin's dive. Often this type is used in corner sofas. You can also unfold it by pulling on the loop.

• Suitable for daily use;
• Sleeping area;
• Ease of operation.

There are no significant downsides to this design.

Kangaroo

This transformation mechanism is almost identical to the previous one. The only difference is the increased height of the supports. Sofas with such unfolding allow you to get the most comfort from sleep.

The pros and cons come down to the increased height of the supports, which gives more convenience, but reduces the level of reliability.

Ankara

Ankar operates on the same principle as the previous two. You need to pull the seat towards you and pull out the block by pulling it up. It is distinguished by increased reliability and spaciousness of the bed.

puma

The design of the puma pull-out sofa is very simple. You just need to pull up the seat, after which the base will stretch behind it. "Puma" has a high demand in the market, thanks to the safety of the floor and convenience.

Advantages:

• Silent folding / unfolding process;
• Ease of use.

Corner models are supplied with a special box for things, which is located on the back.

Sedalift

Sedalift is easy to use. It is ideal for sleeping, but many models suffer from low durability. The instruction manual calls for the lower part to be rolled out, the folded fabric section to be laid out over the extended base.

• Large bed;
• Ease of unfolding.

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

deployable

All types of unfolding are comfortable, but this one causes a special feeling for many. The reason is the elegant appearance of the furniture when folded. This type is perfectly characterized by the word "clamshell". It is also often used in Russian names of subspecies.

In the unfolded state, the sofas resemble a folding bed familiar to many. The berth rests on supports and consists of a rather thin material. It is made up of three elements. It is only necessary to pull the edge of the seat so that the transformer sofa takes on a different look, and its two additional parts stand on supports.

What are the mechanisms of sofas - video:

This fastening does not allow you to use the sofa daily. It has reduced strength, and is also not very comfortable when lying for a long time. As a rule, they are used only in assembled form, and rarely laid out.

french book

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

• Express unfolding.

• unreliability;
• Irregularities on the surface.

It is worth acquiring it only if you have to lie on it extremely rarely. In other cases, it is better to prefer a forward-folding mechanism.

Spartacus

This subspecies was developed by the joint efforts of designers from Russia and Italy. This is the best unfolding sleep mechanism. It is a more durable French clamshell, reinforced with a metal grill.

• Strength;
• Comfort and suitability for daily sleep.

Of the minuses, only that the lifting mechanism requires you to remove the pillows before unfolding.

Rich

This mechanism, also called "American book", is similar to the French version. You just need to pull the seat towards you, after which everything will decompose. It differs in that it consists of two blocks, not three. It also has a thicker surface.

• High strength;
• Compactness.

It has another name - "sedaflex". Of the minuses, only the absence of a linen box.

As the previous version, the sofa of such a plan consists of two parts. The difference is that the transformation requires not raising the seat, but moving the backrest forward, turning the structure over so that the sofa rests on the legs.

• High reliability;
• The presence of springs.

• High price.

The spring mechanism allows you to extract maximum comfort from the furniture.

Accordion

Another popular option resembles, in its principle of action, the musical instrument of the same name. The design stretches in the same way as accordion bellows. Gradually, the sleeping place is pulled out, leaning on the legs. It is similar in size to a large double bed.

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

• Risk of floor damage.

"Accordion" is very convenient to use and has an acceptable cost.

Caravan

The mechanism is based on a metal frame. Unfolds by pulling the seat up. At the same time, two platforms are pulled out under the base. After unfolding, it is comparable in size to a large bed. You can assemble a folding sofa very quickly.

Pluses in durability and simplicity. The only downside is the lack of a linen box.

Ribalto

The popular ribalto folding option is distinguished by a well-thought-out design. It attracts attention with 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, laying them on the floor. This is how the bed is formed. There are models with automatic folding.

• Quick and easy folding;
• Space.

There are no significant disadvantages of the mechanism. Also called "slider" in the angular version.

Folding sofas

Modern folding mechanisms include a third type - folding. It is familiar to anyone who has had an ordinary inexpensive sofa. The main plus is the presence of a large size linen box.

Tango

Such a sofa is very functional, because when unfolded it is able to take several positions. It looks like a book. You need to pull the lower part, after which the back will lower.

• Intermediate folding options;
• Flat sleeping surface.

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

Butterfly

"Butterfly" combines retractable and folding mechanisms. Allows you to fold and assemble the sofa as quickly as possible. First, the lower part is pulled out, then the upper one leans back.

• The speed of the mechanism;
• Bed size.

The disadvantages of a sofa of this form include the risk of damaging the rollers used when rolling out. According to the method of unfolding, the mechanism is very similar to the Eurobook.

Book

The classic mechanism for most people is a book. It is very easy to unfold and fold the sofa book. You need to fold the back back, after which it will lower, increasing the area for sleeping. This sofa consists of a metal or wooden frame.

The parameters allow you to fit inside a section for a large linen box. Other advantages include strength, simplicity and low cost.

Dominoes

The mechanism called "domino" combines rolling out, eurobook and dolphin dive. The lower part is extended, the back is folded and in the form of diving it goes down, forming a place to sleep. The characteristic of the sofa does not allow to include a department for things in the design, which makes the mechanism less attractive.

The main advantage of this triple design is the height of the bed.

Mechanisms for transforming sofas - briefly about each

First, let's define what a sofa transformation mechanism is. Another name is often used - the sofa folding mechanism. Professionals prefer the concept of transformation, so I will use it further.

Under these names lies an element that transforms the sofa into various shapes and positions. For example, a sofa from a sitting position turns into a sofa bed or into a sofa for "relaxation" with a partially reclined back. Another example of transformation is changing the shape of a sofa. For example, a corner sofa can be turned into a straight sofa or vice versa.

Why is it important to choose the right sofa transformation mechanism?

• The mechanism is one of the main ones, therefore the overall service life of the transformer sofa also depends on its reliability.
• The mechanism affects the convenience and ease of converting the sofa into various positions.
• Depending on the transformation mechanism, different free spaces in the room will be required to bring the sofa into the desired positions.
• Depends on the type of transformation mechanism and . After all, it is under it that the mechanism is hidden from our eyes.

Sofas without transformation mechanisms

Such sofas, by definition, do not contain transformational elements and are not able to unfold. Sofas without mechanisms are used to create seating for two or more people. You can offer this option for a small size. Less often they can be found as a sofa for sleeping. Although for people without excess weight, the use of a sofa in this capacity is quite acceptable.

Non-folding sofas can be used as separate sofa modules. By applying several similar modules, especially of different sizes, you can change the shape of a sofa made up of modules.

Monolithic sofa suitable for hallway, for the living room and decorate the kitchen or dining room. Often this type of sofa can be found in public places.

Pros: there is no mechanism, which means there is nothing to break. The service life of monolithic sofas is longer than the service life of folding sofas.

Minuses: no mechanism, no possibility of transforming the sofa. Monolithic sofas are not suitable for organizing sleeping places, especially if you need to put two or more people.

The mechanism of transformation of the sofa "Book"

Sofa "Book" is laid out in two positions: a sitting sofa and a sofa for sleeping.

The sofa is converted into a sleeping position by tilting the back of the sofa back.

During unfolding, you don’t have to move the sofa away from the wall, but keep in mind that the design of the sofa requires free space between the wall and the back of the sofa.

The folding parts of the sofa are wooden or metal frames with spring blocks attached to them. In addition to the spring blocks, another filler can be used - foam rubber or latex. A sofa with a spring block is preferable, as it has the best performance in terms of service life and comfort.

Sofa "Book" often contains a section for bedding inside

Advantages: durable, reliable, time-tested mechanism. Suitable for frequent use and organizing a bed.

disadvantages: the sofa can only be unfolded in two positions - sitting and lying down. During transformation, in the part where the folding parts of the sofa are connected, a bulge or indentation may appear, which will negatively affect the comfort of sleep. The “book” cannot be placed tightly against the wall, since the unfolding mechanism requires free space between the wall and the back.

The mechanism of transformation of the sofa "Tango"

While preparing this article, I came across the fact that manufacturers invent their own names for mechanisms of the same type in terms of properties. Because of this, confusion occurs. So is the case with the Tango mechanism.

The click-clack (clack) mechanism has similar properties. In fact, both mechanisms are similar to the "Books" already described above.

The main difference from the "Book" consists in the possibility of "Tango" ("Click-clack (clack)") to take intermediate positions of the back of the sofa when unfolding.

The back, in addition to full horizontal unfolding, can be in a reclining, half-sitting position. This feature creates additional convenience for relaxation.

Sofas "Tango" have a section for storing the bed

Advantages: the mechanism allows you to fix the back of the sofa in several positions, sofas "Tango" are small in size, when unfolded into a plane, the sofa creates a surface without bumps and bumps.

Disadvantages: there is no way to put the sofa tightly against the wall; when transforming the back, you need a place for unfolding.

The mechanism of transformation of the sofa "Eurobook"

The work of the mechanism: the sofa seat is pushed forward on roll-out rollers, a niche is formed in shape and size identical to the back cushions of the sofa. Pillows fit into a niche, resulting in a flat surface of the bed.

Advantages: ease of converting the sofa into a bed, the simplicity of the mechanism itself - read its high reliability, large and even place to sleep, large niches inside the sofa for storage and bed.
disadvantages because of the wide seats, it is not convenient to sit on the sofa leaning against its back, especially for people with short stature.

Sofa transformation mechanism "Pantograph" ("Tick-tock", "Puma", "Walking Eurobook")

With the "Pantograph" the same story as with the "Tango" sofas. Apparently, for the sake of a red word, sellers and manufacturers have come up with a number of bright names for essentially the same mechanism. So, what else did I manage to meet under the mask of "Pantograph" - "Tick-tock", "Puma" and even "Walking Eurobook". In order not to get confused, I will continue to call the mechanism "Pantograph" (sounds somehow solid and mysterious))) .

"Pantograph" originated as a variant of the "Eurobook" mechanism. The difference is that there are no roll-out rollers in the "pantograph". Otherwise, it has parameters similar to the "Eurobook". Equipped with internal storage niches, it has a large and even bed.

The principle of operation of the mechanism: For unfolding, it is enough to pull up the sofa seat by holding its edge in the middle. Often sofas are equipped with loops - handles for easy unfolding. By pulling up the seat of the sofa, you activate its mechanism, which pushes the seat up and forward and at the same time opens the legs of the support and stands on them. The pillow back is placed in the formed niche. The result is a flat, without visible joints, a place for two people to sleep.

Advantages: sofas with "Pantograph" have a comfortable place to sleep. The mechanism is easily laid out. Such a sofa will not spoil your flooring, because when unfolding, parts of the sofa do not ride on the floor.

disadvantages: the mechanism is expensive because of this, and the cost of the sofa becomes higher. Due to the wide seat, sitting on the sofa is not comfortable, you need to use additional pillows

The mechanism of transformation of the sofa "French folding bed"

The principle of the mechanism: The sleeping surface of the sofa consists of three sections. You need to pull the edge of the seat and stretch them forward. Sections will open and stand on legs - supports. When folding, the sections hide inside the sofa body.

Sofas of this series are not suitable for frequent use because the mechanism is rather weak to wear.

These sofas do not have a place to store the bed - the entire interior space of the sofa is occupied by a folded bed.

When assembled, the "French folding bed" is small in size, but unfolding will require free space (at least 1.50 meters) in front of the front of the sofa

Advantages: in the assembled state it has small dimensions.

Disadvantages: uncomfortable sleeping surface, no bed storage, short service life (about five years)

Conclusion: you can use the "French folding bed" to organize seating and for rare use as a bed - the option of unexpected guests lingering and staying (they won't sleep on such a sofa for a long time and will soon run away))).

Sofa transformation mechanism American folding bed (Sedaflex, Sedaflex)

The principle of the mechanism: The place to sleep has three parts-sections. You need to pull the seat of the sofa, as a result of which the sections of the bed will open and stand on the supports. Unfolding goes in two stages - first one section will open, and then the next one.

In fact, this mechanism is identical to the "French Clamshell" mechanism.

Reliability is its main difference..

The frame of the sofa and the mechanism itself are made of wear-resistant materials. This makes it possible to regularly use "Sedaflex" as a transformable sleeping bed.

Advantages: easy to operate, has good performance of reliability and durability.

Disadvantages: there is no place for linen, the surface of the bed has seams.

The mechanism of transformation of the sofa "Italian folding bed

This transformation mechanism belongs to the double folding mechanisms as well as the American clamshell. The double folding mechanism is a mechanism that is brought into working position in two stages.

The principle of operation of the mechanism

To unfold the Italian folding bed from the sofa to the bed, you need to pull the upper part of the back of the sofa towards you (usually the back has a special loop for this purpose).

• At the first step of unfolding the back of the sofa, together with the pillows, leans forward and then lies down and rests on the seat of the sofa.
• At the second stage the inner part of the sofa design makes a turn around its axis, this is reminiscent of unwinding a mattress rolled into a roll. After this turn, the support legs open, which were hidden before, were hidden and folded inside the structure and the formed sleeping place of the sofa rests on them.

Due to the reinforced springs, the mechanism can be folded and unfolded without significant effort.

Advantages of the Italian folding bed: this mechanism is the most reliable and durable of folding beds, it became possible due to the use of reinforced metal pipes in the frame of the mechanism, the sofa in the folded state has a compact size, when unfolding there is no need to remove the pillows from the seat of the sofa, Italian folding beds among other folding beds have the thickest and most comfortable a mattress for sleeping, in addition, lamellas and belts are used in the frame, which create an orthopedic effect.

disadvantages lack of storage space for linen, high price

The mechanism of transformation of the sofa "Accordion"

The principle of operation of the mechanism: "Accordion" got its name for its similarity to the principle of operation of accordion bellows (stretch back and forth). The sleeping space of the sofa also stretches forward, as it were, while bringing the sofa to the sleeping position, and rests on the extended supports. After the transformation, we have an even, although with minor seams a spacious place to relax and sleep.

The convenience of the sofa "Accordion" in its compact size when folded. But we must not forget that to unfold the sofa you will need free space in front of its front part (you need at least 1.50 meters)

Models "Accordion" are often equipped with an additional cabinet for storing bedding. Such a cabinet is located near the back of the sofa.

There is no storage space inside the sofa itself, the space is occupied by a folded sofa.

Advantages: Reliable and load-resistant mechanism that increases the life of the sofa. Supplied with additional cabinets for storage. Ease of bringing the sofa to the sleeping position.

Disadvantages: the sofa, when brought into the sleeping position, rides on the floor, so it can damage the flooring.

The mechanism of transformation of the sofa "Spartacus"

The principle of the mechanism: Triple folding mechanism. It is necessary to pull the seat of the sofa and it will decompose in three steps while standing on extended legs.

The design of the mechanism was developed by Italian engineers. This mechanism belongs to the metal-frame mechanism. The frame is made of shaped pipes on which a dense mesh made of metal rods 4 mm thick is mounted. The frame consists of three sections. The mesh creates a good orthopedic effect. On top of the mesh is a polyurethane foam mattress. It is comfortable to sleep on such sofas. The design of the mechanism provides a large bed in length, which is especially important for tall people. The mechanism is very reliable because it does not contain wooden and plastic parts.

Advantages: reliability and durability, easy to unfold, can be used daily, flat and large bed
Disadvantages: there is no place to store bedding, since the mechanism occupies the entire interior space of the sofa when assembled, you need to remove the sofa cushions before unfolding.

Sofa with unfolding on the floor

The principle of operation of the mechanism The sleeping place consists of two sections. When folded, the sections are hidden inside the sofa body. To unfold the sofa, you need to pull up on the inner edge of the sofa seat. Then, pull the sections forward towards you. The berth has no supports and unfolds directly on the floor.

It cannot be said that the sofa is comfortable for sleeping, since the joints of the sections are noticeable and the bed itself is located very low. Therefore, such models can be used for occasional use as a bedroom. But for sitting it is quite an acceptable option.

Advantages: compact dimensions in the assembled state, the cheapest type of folding sofas.
disadvantages: not comfortable to sleep, no storage space for bedding

The principle of the mechanism: The sleeping place consists of two segments. In the assembled state, the segments are in the sofa body. To unfold the sofa, you need to pull the bottom of the front. After that, it will roll forward into the working position. All that remains is to fold the pillow into the vacant seat. As a result of the transformation, a comfortable place to sleep is formed.

Roll-out sofas are durable and reliable models. Well suited for frequent use. Contain internal space for storage of bed linen.

Advantages: the most reliable, have a comfortable place to sleep and compact dimensions when assembled.

disadvantages: roll-out sofa rollers can ruin the flooring when unfolding, the bed has a low height

The folding mechanism of the sofa "Konrad" ("Telescope")

The principle of operation of the mechanism: "Konrad" consists of three sections. To unfold the sofa, you need to pull the lower part of the sofa from the front. In this case, the sections roll out one after the other. Because of this feature, the mechanism was nicknamed the "Telescope". Sections roll out and stand on supports.

"Conrad" is a subspecies of a roll-out sofa. The main difference is the large height of the bed.

Advantages: reliable mechanism suitable for daily use, sofas have a compact volume, equipped with a box for linen, comfortable for sleeping

Disadvantages: mechanism and sofa are heavy

The mechanism of transformation of the sofa "Dolphin"

The principle of the mechanism: To unfold the sofa, pull the front of the sofa from below. As a result of this, a section hidden inside the sofa body will roll out onto you. Inside the roll-out section there is a pillow with a strap. You need to grab the strap to pull the pillow up. She will "emerge" and stand on the same level with the cushion-seat of the sofa. Voila, the sleeping place is ready.

The Dolphin mechanism is mainly used in the construction of corner sofas. Places for storing the bed are not located in the roll-out part of the corner sofa. The mechanism exerts a significant load on the body of the sofa, so when buying, pay attention to the material of the body. Knots are not allowed if wood is used.

Advantages: ease of unfolding, the optimal height of the bed.

disadvantages: not durable.

The mechanism of transformation of the sofa "Elf"

The principle of the mechanism: The mechanism unfolds easily. Armrests are bred on the sides and a berth is formed.

"Elf" refers to metal-frame mechanisms. The frame is made of metal profiled pipes. Wooden slats. Armrests are adjustable in height and have several positions. This feature allows you to create the most comfortable position of the armrests for the reclining position.

Advantages: compact model of sofas, a good flat bed, the lamellas give a good orthopedic effect, the armrests are adjustable, you can create a sofa for yourself.

Disadvantages: you can not put the sofa close to the wall, the bed is in the same place as the seat.

Sofa transformation mechanism "Recliner"

"Recliner" got its name from the English word recline - reclining or leaning back

The principle of the mechanism: The sofa transformation is controlled by complex mechanisms hidden in the sofa body. With their help, you can adjust the inclination of the back of the sofa and extend the footrest to a predetermined distance and at a certain angle.

Some models have vibration massagers built into the sofa cushions. Particularly advanced sofas have built-in electric motors that control the transformation of the sofa using a remote control.

There are models with "memory" that can adjust and remember the settings of the mechanism made directly for your body.

Advantages: very easy to manage, have fine settings - you can create a sofa for yourself.

Disadvantages: high price, used only as a place to relax, as there is no place to sleep

General conclusions

• Pay close attention to the mechanism when buying a sofa. The ease of use and life of the sofa will depend on choosing the right mechanism.
• Match your needs with its capabilities. How often will you lay out the sofa, what space do you have allocated for installing the sofa, especially when unfolded.
• Do not take a sofa with a obviously inappropriate mechanism just because the color is cool or because the neighbors have one. Choose individually for your needs.

Sofa transformation mechanisms - video review

For greater clarity, I also want to offer a video plot that describes the mechanisms of sofas. True, they have already been discussed above. But, as they taught at school - "Repetition is the mother of learning)))", and this video will facilitate and consolidate your understanding of the topic.

Now you know everything you need to make an informed choice about the mechanisms for transforming sofas. Hope it was helpful.

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.
