Mechanisms for transforming sofas. What are they and how do they differ? Mechanisms for transforming sofas - briefly about each Sofa folding options

Buying a sofa is a very responsible process, because such furniture is bought for more than one year. The choice must be approached with special care so that the new sofa is comfortable for all family members, successfully harmonizes with the interior and pleases with its functionality for a long time.

First of all, the sofa is a comfortable relaxation area after a hard day, a place for friendly gatherings and watching movies. Often it is also used as a place to sleep. When buying, we usually pay attention to the appearance, but it will be much more important to make sure of the quality of the material and check the folding mechanisms of the sofas.

Before you go on a furniture shopping trip in search of a sofa, answer the following questions:

1. How much space do you intend to allocate for the sofa when folded and unfolded?
2. How often are you going to lay out the sofa?
3. In what mode will the sofa sleeper function: daily or as a guest option?
4. What load should the sofa withstand?
5. Do you need a special place to store clothes?
6. How much are you willing to spend on a purchase? Which model should you pay attention to: a budget option or a sofa with a more complex mechanism and reliable details?

Types of mechanisms, pros and cons

Types of sofas by folding mechanism:

• retractable, or withdrawable (on rollers): withdrawable, dolphin, eurobook, conrad, pantograph;
• folding: tango, book, elf;
• deployable: accordion, French cot, American cot, Spartak.

Let's consider in more detail each of the options.

Book

Having such a mechanism for transforming sofas, a piece of furniture is converted into 2 positions: a seated version and a sofa for sleeping. To turn the sofa into a sleeping place, its back is simply folded back. It will not have to be moved away from the wall during this process, since during installation it will be necessary to take into account that the design of the furniture requires a small gap between the wall and the back.

Parts of a sofa with a "book" mechanism are two metal or wooden frames with fixed or other soft filler. At the bottom, there is often a compartment for storing clothes.

Pros:

• strength;
• reliability;
• ease of use;
• can be used frequently without the risk of breakage and wear.

• has only two positions - lying and sitting;
• the inability to move the sofa tightly against the wall.

Tango

"Tango" is the prototype of a sofa folding system called "click-clack". Many manufacturers seek to simply surprise the buyer with a beautiful new term. In general, this system is very much like a classic "book". There is only one difference - when unfolding, such a sofa can also take intermediate positions, and not just “sitting-lying”. The backrest can be adjusted to a comfortable level. These sofas are equipped with a bed storage box.

• fixation of the back in several positions;
• compact size;
• when unfolded, the sofa creates a surface without bumps.

Minus - you can not attach the back tightly to the wall.

Eurobook

Such a mechanism for unfolding classic sofas, like the Eurobook, is easy to identify by pushing the seat forward on roll-out rollers. In this case, a niche is formed in which a part of the sofa, which previously served as the back, fits.

• ease of converting the sofa into a bed;
• reliability of the mechanism;
• plenty of space to sleep;
• large niches for storage.

Minus — due to excessively large seats on the sofa, people with small stature and children will not feel comfortable, because they will not be able to lean on the back.

Dolphin

This is the most popular mechanism for transforming corner sofas. To unfold it, you need to pull the loops attached to the section under the seat. The movement should be up and towards you. The section will roll out and stand next to the seat, forming a large bed. The laundry box is located in the non-roll-out part of the seat.

Note: The dolphin mechanism exerts a heavy load on the sofa body, so you need to make sure that it is made of high-quality wood.

• comfortable bed;
• simplicity and ease of deployment.

Minus - not very long service life with the active use of the mechanism.

Pantograph

These types of folding sofas can often be found under the name "puma" or "tic-tac". This system arose as a variant of the Eurobook, only without roll-out rollers. Inside there is a spacious bed box.

To transform this sofa, you need to pull up the seat of the sofa, grabbing its edge in the middle. With this movement, you will activate the mechanism that pushes the seat up and forward and opens the legs of the support. In the resulting niche, lay the back-pillow.

• comfortable place to sleep;
• easy folding mechanism;
• does not spoil the floor covering with rollers.

Minuses:

• the mechanism is expensive;
• very wide seat.

The sleeping surface of such a sofa is represented by three sections. To straighten them into a plane, you just need to pull the edge of the seat. For frequent use as a bed, such furniture is not recommended, since these types of sofa folding mechanisms wear out very quickly.

Tip: For unfolding, you need to take care of the presence of a fairly large space.

Plus - when assembled, this sofa is very compact.

Minuses:

• the sleeping surface has irregularities;
• short service life.

Roll-out sofa

The bed has two segments that are hidden in the sofa body. To unfold, you need to pull the bottom part so that it rolls forward. After that, the pillow leans back into the vacant space.

• very durable and reliable mechanism;
• comfortable place to sleep;
• compact dimensions when assembled.

Minuses:

• roll-out rollers can scratch the flooring when unfolding;
• low bed.

Accordion

"Accordion" got its name for some resemblance to the musical instrument of the same name. The sleeping space of the sofa stretches in a peculiar way, moving forward at the moment of unfolding, and then rests on the extended mobile legs. When folded, such a sofa has compact dimensions, but more space is required for transformation. The storage compartment is located in the back of the sofa.

• reliable and stable mechanism;
• long service life of the sofa;
• ease of transformation.

Minuses:

• there is no built-in place for linen;
• draw-out type of mechanism can cause scratches on the flooring.

Spartacus

To transform such a sofa into a comfortable place to sleep, you need to pull the seat so that it decomposes in three steps and stands on extended legs. This type of folding sofas was jointly developed by Russian and Italian craftsmen. Such furniture is very well suited for sleeping. The design of the mechanism provides a long berth. In fact, this is a more durable French clamshell, complemented by a welded metal grill.

• strength and durability of the mechanism;
• ease of use;
• as a bed can be used often;
• comfortable sleeping place.

Minuses:

• there is no place to store the bed;
• before unfolding the sofa, you need to remove it from it.

Note: There is also a mechanism for laying out Ifagrid sofas, which is similar to Spartak, but also has some differences.

Conrad or Telescope

To expand such a sofa, you need to pull on its lower part. The sections will roll out one after the other, like a telescope, and stand on the supports.

This type of furniture differs from classic roll-out sofas by the large height of the bed.

• reliable mechanism;
• can be used daily;
• compact volume;
• there is a box for linen;
• sleep comfortably.

Minus - the sofa is very heavy due to the massive mechanism.

Sedaflex (American folding bed)

Such a sofa unfolds like a French folding bed, but unlike it, it has not a three-fold, but a two-fold system and a thicker mattress.

• very strong mechanism;
• compact;
• has a quality .

Minuses:

• no storage box.

Elf

This is a sofa with a swivel transformation mechanism. The armrests at the time of the transformation of the bed are bred to the sides, and a comfortable place to sleep is obtained. The armrests in this sofa can be adjusted in height and have several positions.

• compact model;
• comfortable bed;
• due to the use of lamellas, an orthopedic effect is obtained;
• Armrests can be adjusted to suit individual needs.

Minuses:

• the sofa cannot be leaned close to the wall;
• the bed is located in the same place as the seat.

The name of this type of mechanism comes from the English "recline" - to lean back. The transformation takes place thanks to complex mechanisms hiding in the depths of the sofa. With their help, you can adjust the inclination of the backrest and push the footrest to the desired position. In some models, there are also special pillows with vibration massage. The most expensive models are equipped with an electric motor that is controlled by a remote control.

Pros:

• ease of management;
• you can adjust the sofa to the needs of your body;
• comfort in any position.

• very high cost;
• you can only sit, because there is no position for sleeping.

Sofa with unfolding on the floor

The bed has two sections. When folded, they hide inside the sofa body. To convert such a sofa, you need to pull up on the inner edge of the seat. Then make a soft jerk forward and on yourself. The sleeping place does not provide for any supports and is laid out directly on the floor.

• small dimensions when folded;
• the cheapest type of folding sofas.

• not a very comfortable bed;
• there is no area for storing bedding.

What to choose?

As a result, you can determine which of the sofa folding mechanisms has become the best in its category:

• eurobook - the most reliable mechanism;
• tango is the most comfortable to sit on;
• dolphin - the most spacious;
• pantograph, accordion and roll-out - the most comfortable for sleeping;
• tango, eurobook and roll-out - have special storage compartments;
• roll-out and elf - the most compact;
• The book is the most affordable.

When buying any sofa, be sure to inspect its folding mechanism, consult the seller on this matter, ask questions and demand answers to them. The service life of the sofa and the convenience of its use depend very much on the correct mechanism. If the sofa will rarely be laid out, then you should pay attention to compact models, but not intended for frequent transformation.

It is difficult for any of us to imagine a living room without a sofa. This soft component of the interior gives people a feeling of warmth and comfort, a sofa in any home occupies one of the most important places. On it, people relax, play, communicate with family and loved ones, as well as read, watch TV and sleep. In order to decide on his choice, you need to clearly understand what models exist and what functions they perform.

Now more and more new corner models and designs for the house are being produced all the time. In such a number of offers, it is quite difficult for the buyer to make a choice and understand which type is right for him. In most cases, a person chooses a model based on its appearance and the material from which it is created. But with such indicators it is difficult to achieve complete comfort in using the sofa. For example, such a choice is suitable for furnishing a room and giving it aesthetics, but not used often. For the same purposes, there are monolithic sofas, otherwise they are called non-folding. They can be seen in public places and shopping stores.

It is a completely different case when a sofa is bought for frequent use in everyday life. So, we can assume that such a model will be laid out every day for sleep. . To choose the right model and not to make mistakes, you should know and understand what are the mechanisms for transforming sofas.

You should also provide for other criteria for the chosen model: the size of the space required for the sofa, the ease of transformation, the availability of space where to put the bed linen. You should also determine for yourself which type of sofa is better.

The classification of all designs of sofas is carried out according to:

1. Transformations.
2. Design features of furniture.
3. Appointment.
4. Size and capacity.

Types of mechanisms

Names of sofas

Classification by purpose

All models can be divided according to their purpose:

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

With all these varieties, sofas and their mechanisms will differ significantly from each other, so you should accurately determine the design of the sofa and its purpose. In most cases the purpose can be determined by the material of which the furniture is made.

Those sofas that are sheathed in leather or more budget materials are usually located in offices or kitchens.

Apply a variety of layout mechanisms for sofas. There are no universal options. Depending on the method of operation, the size of the room and some other conditions, one or another mechanism for transforming the sofa is selected. In order not to make a mistake, you need to listen to the advice of experts. They will help you understand what factors you need to pay attention to in the first place.

When studying which sofa transformation mechanism is better, a number of recommendations should be taken into account. There is a generally accepted rule. All sofas are conditionally divided into guest types and designed for daily sleep. If the mechanism is chosen correctly, the furniture will last a long time and its operation will be comfortable.

If the sofa will be laid out often (sleeping variety), you should not purchase products with a complex layout procedure. In this case, the simpler the better. Guest sofas, on the contrary, are not designed for the daily movements of the system, so their mechanism will not be as strong as that of sleeping varieties.

Attention should also be paid to such criteria as the maximum load of the bed, the orthopedic qualities of the model, its appearance, the layout procedure, the comfort of the bed, and also the convenience in the sitting position. Therefore, the sofa transformation mechanism is an important factor influencing the choice.

Guest models

Sofas with "Clamshell" mechanism

The folding bed sofa transformation mechanism has several popular design options. The principle of transformation here is simple: the bed is located directly under the seat. For the front panel, which is located below, the seat moves forward. There is a French and American cot, their principle is very similar.

The French one is pulled out in the form of a scroll, which unfolds in 3 stages. This mechanism is compact in size, so it is built into even very sophisticated sofas. However, this model is not used on a daily basis.

The American clamshell is designed for heavy loads. This sofa is practical and durable. However, this feature significantly raises the price of this furniture. To transform the sofa, you need to lift it a little, and then pull it towards you. This type of mechanism does not harm the flooring, but it needs to be lubricated periodically to avoid squeaks.

Withdrawable mechanism

One of the best options for sleeping is a roll-out sofa. The transformation mechanism here is very simple. The berth is obtained by rolling out additional sections from under the base. Due to its simplicity, the presented mechanism is called one of the most reliable.

Another advantage of such products is the absence of requirements for the size of the room. It is installed even in small rooms. Moreover, in the unfolded state, the place to sleep will be long and even. The disadvantage of such mechanisms is the exactingness of the type of flooring. It should be strong, not sag under the weight of the sofa. In the process of transformation, the base slides on the floor. Nothing should interfere with this movement. It is better if the selected model of the presented type has rubber wheels.

Sofas with accordion mechanism

The mechanisms for transforming accordion sofas are gaining more and more popularity. It is very easy to apply in everyday life. The principle of the design device is to push the accordion. To do this, the seat is slightly raised. Next comes the click. The back of the two parts (in the normal state, it is folded with a house) is stretched. It resembles the movement of an accordion.

With the help of such a transformation, a flat surface is formed. When unfolded, the sofa looks like a regular bed. Usually "accordion" has removable covers for all soft elements. This makes the cleaning process easy. In the kit, almost all models have a linen box. In some cases, other decorative elements may be present. It is better if the basis of such furniture is a metal frame, steel frames. The mattress can be chosen orthopedic. For a small room, this option is acceptable, but you need to consider how much space the sofa will take up when disassembled. On the way of its layout there should be no extraneous things. There should be at least 0.5 m of space left to the opposite wall when the "accordion" is disassembled.

Sofas with the Dolphin mechanism

Check out the Monza sofa with the Dolphin mechanism!

The dolphin sofa transformation mechanism can also be called a kangaroo. It is most often found in sofas in the form of an angle. The front part slides out. An additional pillow is taken out of it with the help of a loop. She forms a bed. These sofas are quite large. The storage box is hidden in the corner module. The advantage of this model is a reliable and simple mechanism. This is an option for daily sleep. It is able to withstand heavy loads (about 200 kg). When laid out, an additional part of the structure takes up a minimum of space in the room. It should also be noted that the bed is spacious and has a fairly high rise above the floor level. The cost of the presented furniture is relatively low. This makes the "dolphin" very popular.

Swivel mechanism

One of the most modern is considered a corner sofa with a swivel transformation mechanism. It works very simply. One half of the furniture is rolled to the side 90º, and then it must be rolled to the other part of the sofa. It does not require the use of significant physical force. All movements are smooth. After the transformation is completed, the turning part is fixed. This creates a comfortable and spacious bed. The simplicity of the design makes the mechanism durable. It is possible to use orthopedic sofas for sleeping. It comes with a spacious bottom drawer for storage. On sale, such varieties of sofas are still quite rare. Their prices are above average. Therefore, if you want to purchase an easy-to-use, reliable and modern sofa, which is the corner swivel mechanism, you will have to spend some time looking for a responsible, trusted supplier.

Sofas have become such an integral part of our lives that today it is difficult to imagine a living room without this interior element. On modern models, you can not only sit comfortably while watching your favorite movie, but also sleep, play with children and just be proud of a stylish solution for your home. Beautiful sofas of various designs will help transform the look of your home and use its space wisely.

Types

The variety of sofas today is striking and somewhat disorienting to a potential buyer. It is one thing to choose a model from five options, and another from a thousand. However, here it is important to calm down and not run after the first color you like, because the main goal of the right sofa is the convenience of its owner. The comfort of the model depends on one of the key factors - the folding mechanism.

It is worth noting that not every sofa is transformed into a sleeping place and has folding properties. For example, monolithic sofas find their purpose in offices, because a sleeping place for a working room is irrelevant, and therefore there is no need to overpay for it.

Nevertheless, if upholstered furniture is selected for daily use at home, it is important to make a choice. the following layout mechanisms:

• "book";
• "Eurobook";
• "click-clack";
• "tic-tac";
• "accordion";
• "roll-out";
• "cot";
• "dolphin";
• "konrad".

"Book", "eurobook" and "click-clack" are related mechanisms. Their feature is to lift the seat and pull it towards you. The back and seat are thus reunited and represent a large bed. More modern models are equipped with a click-clack mechanism. Unlike its predecessors, it has several positions, for example, reclining, and also allows you to create an imitation of armrests.

The accordion sofa is also included in the classic and familiar mechanisms, which are also quite reliable. The backrest in the assembled state consists of 2/3 of the bed, which, when pulled out, reunites with the third part and forms a comfortable bed.

The roll-out mechanism embodies ingenious simplicity. When the seat is pulled forward, all parts of the steel seat are pulled behind it, after which one part is placed on the wooden frame. The clamshell French and American did not just deserve its name. The familiar folding bed extends from the seat and rests on strong iron legs. The disadvantage here can be considered a lower density of the bed.

In addition to comfort and convenience, some mechanisms are also preferred because of their careful attitude to floor coverings. So, not wanting to constantly correct a carpet that has moved out or scratch linoleum or laminate, you should pay attention to the mechanism "tic-tac". Its seat does not extend, but rises, which eliminates any movement of the sofa parts on the floor. At the same time, the back of the model is placed in the vacated space and becomes a spacious sleeping place.

The beautiful name of the sofa "dolphin" is also not invented just like that. When assembling the sofa, part of the bed goes under the bottom of the seat, reminiscent of the dive of this graceful inhabitant of the seas. Sofa "konrad" - one of the most beautiful and comfortable mechanisms for sleeping. Parts of his sleeping place, rolling forward, have a spring block in their arsenal, which has orthopedic support for the body during sleep.

And if everything is clear with the mechanisms, then it's time to turn to another important point of a beautiful sofa - the choice of upholstery. Sofas can be divided according to this feature into two groups:

• leather models;
• fabric.

The first option involves the use of natural and eco-leather. Their price segment is vastly different, as is the wear resistance period. Natural models will serve for many years without cracking and delighting with softness. Fabrics for upholstery of upholstered furniture in some cases have complex names, but their knowledge will help to acquire a quality model. So, the most affordable option is natural cotton, which can last about 5 years without any processing.

If the model in your dreams should have velvety and comfort, the best solution would be upholstery with flock, jacquard and chenille. If the sofa involves a complex, well-drawn print, it is best to use tapestry. Its weaving is made with a mixture of cotton, wool and synthetic threads. Arpatek is considered a luxurious innovation. This material resembles the texture of thin delicate skin, while consisting of a fabric web. The wear resistance of such models is incredibly high.

And in addition to fabrics and mechanisms, beautiful models have a different shape. For example, a corner sofa is perfect for placing a sofa in one of the corners of the room. If the sofa is located in the center, choose a classic model with armrests.

The most fashionable colors and materials

Designers this year tried to create not just beautiful sofas, but elements of comfort and warmth at home. For example, smoothness of lines has become an important feature. The colors this season are also full of warm radiance in shades of wood, sand and beige. Stylish models today include several colors and textures. So, one of the most popular is natural wood with its characteristic pattern. In this case, almost everything is suitable for fabrics, for example, a vintage-style tapestry.

In addition to fabrics, designers consider leather to be very relevant. And if for some a leather sofa is associated with an office setting, experts offer combined models.

The last point is given special attention. Light and white sofas are decorated with contrasting pillows in the color of young greenery. Bright models, on the contrary, become more subdued due to accessories of a neutral shade.

How to choose?

Before going to the store in search of the most beautiful model, it is important to decide on the purpose of its purchase. Sofas in the hallway, living room or nursery have completely different priorities in choosing, as well as purely individual sizes.

Before going to the store in search of the most beautiful model, it is important to decide on the purpose of its purchase. Sofas in the hallway, living room or nursery have completely different priorities in choosing, as well as purely individual sizes. You should start here with the living room. This room is considered the soul of an apartment or house, and the soul must be beautiful in everything. Both monolithic and folding sofas are suitable for the living room, if the living room also serves as a place for residents to sleep. So, before buying, it is important to measure the room and determine for yourself the desired size of the sofa, which will not hamper the household and interfere with free movement around the room. Today, almost every manufacturer offers to make furniture according to individual sizes, which is an indisputable advantage of modernity.

It is important to measure the vending model not only assembled, but also disassembled. For a cramped living room, compact and small sofas are a good choice. A room that is not limited by strict frames will organically accept unusual models of various shapes. And if all the parameters agree, you can proceed to the inspection. High-quality models never creak, and the mechanisms work smoothly and effortlessly. It is good if each of the household can easily assemble and unfold the sofa. Convenient for all details will prevent breakage from incorrect and inaccurate layout. In the unfolded state, the entire structure should be as stable as possible.

And also soft creators of comfort can be successfully located in the hallway, because sometimes after a hard day's work you really want to sit down on something comfortable without taking off your shoes. A small sofa will perform this task as well as possible and will not take up much space, contrary to stereotypes.

Modern models for the hallway are performed:

• in the form of soft banquettes without a back on carved legs;
• small sofas with a backrest without armrests;
• sofas with back with metal forged and wooden armrests;
• in the form of a sofa with a folding bed;
• in the form of an angle sofa
• narrow sofa with practical drawers under the seat.

When choosing, you should focus on the shape and size of the hallway. A narrow and small rectangular hallway can only accommodate a bench. It is not recommended to load it with lockers and other details. Simple models in this case look more harmonious and lighter. The square entrance hall is made cozier by the corner model of the sofa and even the model with armrests. If this part of the apartment or house pleases with spaciousness, then a full-fledged sofa will turn the hallway into another place to relax.

But for a children's room, an important criterion, first of all, is safety. It shows up in everything. Environmentally friendly materials such as wood, rounded edges and a minimum of synthetics in fabrics will be the key to a successful purchase.

How to care?

When a sofa is bought and pleases the eye, you should not relax, because care is another key point in the long-term operation of furniture. So, fabric upholstery is cleaned with a soft brush or vacuum cleaner every three days. This action allows you to remove daily dust, preventing its deep penetration into the fibers.

If visible contamination nevertheless appears, you should turn to specialized products for cleaning the upholstery, remembering the general rules for all types of fabric:

• all pollution are removed in the direction of the pile;
• spilled liquid it is absorbed with a soft cloth, without rubbing the wet spot;
• stain being processed from edge to middle.

Treating leather and keeping it looking presentable is no easy task. First of all, a leather sofa should not be closer to the batteries by more than a meter. This will prevent cracking of the skin. And on the leather model, it is not recommended to put your favorite colored rugs and capes, thereby preventing skin staining. Once every few days, such furniture is wiped with a dry soft cloth.

It is worth noting the need for wet cleaning with microfiber once a month. Visible dirt can be removed with soapy water. After the procedure, the surface is wiped dry. If the spots are difficult to remove, the most reasonable solution would be to use special products for the skin.

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 unfold 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 these 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), PPU 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 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.
