Types of sofas. How to choose a sofa by type. Consider the mechanisms of modern sofas: types and purpose What is the name of the sofa that moves forward

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

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.

French cot

The French folding bed has a triple folding mechanism, which is located under the seat cushions. This model is new and not yet widespread enough. Before you unfold the sofa with this mechanism, you need to remove the pillows. After that, it is necessary to pull the handles and extend the lower part, and only then the structure gradually unfolds.

Be sure to study the main characteristics of the sofa:

Which upholstery is more practical

Folding sofa beds are considered practical products for daily use. But when choosing, you should pay attention not only to the type of transformation of the mechanism, but also to the upholstery. And it can be made from different materials.

Consider which upholstery for sofas is considered the most practical:

• jacquard - this material has a dense, high-quality basis. It is not subject to abrasion, practically does not fade under the influence of sunlight. Able to maintain the original external qualities for a long time;
• flock - many experts say that it is flock fabric that is a practical material for upholstery of sofas. This is due to its good qualities - durability, wear resistance, strength, environmental safety. In appearance, it resembles velvet;

Basic requirements for the filler

A modern sofa bed can have a variety of types of fillers, on which the convenience and service life of the product depends. Three types of filling material are commonly used:

• spring bases;
• polyurethane foam filling;
• fillers with a combined structure.

Fillers, consisting of springs and polyurethane foam material, have the same base. The main thing is that they are of high quality. In addition to springs and polyurethane foam, materials such as latex, felt, batting can be used.

Products that additionally have latex, batting, felt in filling are perfect for children's rooms. Sofas can be used as a sleeping place for boys and girls aged 5 years and older.

Models with orthopedic mattress

Currently, modern manufacturers of upholstered furniture offer a large number of models of sofa beds, which are equipped with a comfortable orthopedic mattress. They are perfect for any apartment, regardless of the interior and area.

What are the advantages of orthopedic mattresses? Consider the main positive points:

• orthopedic mattresses are designed specifically for humans. It does not put a load on the spine, does not cause discomfort and inconvenience;
• products are able to withstand increased loads, they do not bend or sag;
• can withstand repeated folding and unfolding of sofas;
• the surface of orthopedic mattresses has a relief structure, due to which normal ventilation is carried out, which protects against fungi and mold.

Popular manufacturers of such models include the following companies:

• Ascona is a well-known manufacturer of comfortable upholstered furniture with orthopedic mattresses. When developing, the anatomical features of the structure of the human spine are taken into account, so sofas will never cause inconvenience and discomfort. This manufacturer produces a bed with a sofa below, which combines several functions at once. It is also equipped with an orthopedic mattress with a flat surface. Popular models of sofas from this manufacturer include Karina, Vega, Antares, Karina angular, Orion, Antares angular;
• manufacturer called "A lot of furniture". This is a popular network of furniture factories, which is distributed throughout Russia. In the assortment you can find high-quality models of sofa beds with a structure made of durable solid wood. They are all equipped with a comfortable orthopedic mattress.

• Ami furniture is a popular furniture brand from Belarus. The manufacturer offers high-quality models of sofa beds, which are made of durable construction with good filler. The following models are considered popular - Jacqueline, Fiesta, Martin, Chester, Fortuna.

When choosing sofas that can be used as beds, you should pay attention to many qualities. It should be borne in mind that this furniture will be used not only for meeting guests or for a place of rest in the living room, but also for a full-fledged sleeping place.

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.

Choosing among the many types of transformation of sofas, you need to consider whether you will lay out a bed every day, or only occasionally, when guests rush into the house.

Book ("click-clack")

Mechanism: to expand the sofa, lift the seat and pull it towards you. It is reliable, time-tested.

• Three positions of the backrest: sitting, lying, "relax" (intermediate position with a half-reclined back).
• Compactness. Doesn't take a lot of space to spread out.
• As a rule, it is possible to provide a linen box.
• The sleeping place is flat, without "kinks".

Eurobook

Mechanism: The seat is pushed forward, after which the back of the sofa is lowered. In fact, it is difficult to call similar mechanisms: the seat leaves by sliding along the guides, the backrest is lowered in manual mode.

• Durability: Simplicity sofa folding mechanism eliminates breakage.
• Large selection of sizes.
• Large linen box due to the lack of internal parts of the mechanism.
• Flat sleeping surface.

Eurobook "Tick-Tock"

Mechanism: among others types of transformation of sofas this one is especially respectful of the flooring: the wheels do not move on the floor, the seat moves along a trajectory resembling a semicircle.

• Scratches on parquet, linoleum and other floor coverings are excluded.
• Doesn't require a lot of layout space.

Accordion

Mechanism: this “musical” name was given for its similarity with the principle of stretching the bellows of this musical instrument. The seat raises until it clicks, and then extends to the stop.

• Minimum assembled size.
• Large bed size.
• mechanism reliability.

Withdrawable

Mechanism: The seat pulls all other parts along with it. To unfold the sofa, you need to pull the seat strap hidden at the bottom.

• Of all sofa folding mechanisms this one is the most reliable.
• Takes up little space when folded
• Large size bed with a small size of the folded structure.

Cot

Includes the following types of sofa transformation: American and French. They have some differences, but are similar in that the assembled bed is under the seat.

french look

Mechanism: the seat must be pulled out towards you and then up, after that the folded sofa should be “unfolded”. Before that, you need to remove the pillows.

• When folded, it takes up little space.
• When unfolded, it has a fairly large bed.

American view ("sedaflex")

Mechanism: unfolds similarly to the French mechanism, while the headrest does not need to be removed, it will automatically move to the desired position.

• More durable mechanism than the French counterpart.
• There is no need to dismantle structural elements.

Dolphin

Mechanism: the movement of the sleeper at a given sofa folding mechanism reminiscent of a dolphin dive. It is necessary to pull the strap attached to the seat and pull it out completely.

• The most durable of all types of transformation of sofas. Suitable for daily unfolding.
• The sleeping place is large, flat.
• Easy to unfold and fold.

Conrad

Of all types of transformation of sofas this option is the most convenient for sleeping, as it allows the use of spring blocks in the design, which is most beneficial for health and creates comfortable conditions for sleeping.

Mechanism: the part located under the seat extends and stretches further, dragging the seat with it, and then part of the back, after which the first part rises up, on the same level with the seat, and the part of the back falls to the same level.

• A sleeping place close in quality to an orthopedic mattress.
• Significant space saving when folded with a relatively large bed.
