For a rational choice of a sofa, you should first find out what types of sofas exist. What are their differences, advantages and disadvantages.

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

What sofas are depending on the design

In this section, I have selected the most significant design differences between types of sofas. These can be attributed

• the ability of the sofa to change shape and size without unfolding - in this part, I divided the sofas into stationary and modular
• the ability of the sofa to transform - unfold
• types of sofas depending on the type of filler
• types of sofas depending on the fabric for upholstery sofa (I think this indicator is the least significant)

Now about each design difference of sofas in detail.

Stationary, modular and island types of sofas

On this basis, sofas can be divided into three groups - stationary, modular and island. Let's figure out which ones are better.

Stationary sofas

Stationary sofas are sofas that have a fixed size. They do not allow you to change the shape and size of the product. Usually, a stationary sofa is placed along the wall. Often, the back wall of the sofa has a more economical finish (for example, felt), which differs from the main upholstery.

In turn, stationary sofas can be divided into:

Direct sofas - usually used in small spaces. There are folding and non-folding

Corner sofas - there are also folding and not folding .Corner sofas require more space.

• To the virtues stationary sofas can be attributed to the fact that when unfolding the sofa turns into a comfortable bed. You can use this sofa for both sitting and sleeping. The prices for such sofas are also quite lifting.
• disadvantage stationary sofas is a certain massiveness and not the possibility of changing the shape and size.

Modular sofas

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

Of course, such models are mobile and suitable for creative individuals. You can change the configuration and general appearance of the sofa. Due to the compact size of the modules, modular sofas are easy to move and transport.

• Advantages of modular sofas mobility in every sense, transformation and change in the general appearance of the product
• To disadvantages can be attributed to the fact that such sofas often do not have a bed and have a higher price than stationary sofas, the range of modular sofas on sale is much smaller than the range of stationary sofas.

This type of sofas is used to organize places to relax. At the same time, the sofa is not placed along the walls, but far from them. The sofa forms a semblance of an island. Island sofas have an attractive look from all sides. In shape, they can be round, semicircular, oval and rectangular. The use of an island sofa requires that there is sufficient free space in the room. The approach to the "island" should be free from all sides. Island sofas come in a variety of sizes. From one or two local to 5-6 local versions.

• Advantages of island sofas mobility, stylish and unique appearance
• disadvantages sofas do not have a bed, require large spaces, have a high price

Conclusion: if you need a sofa to organize a sleeping place, then you need a stationary type of sofa. If you want to organize seating and daytime activities, take a look at the modular versions. An island sofa is good if there is a lot of space in the room.

The design features of the sofas allow you to create sofas of various shapes. A detailed description of the possible forms of the sofa in this article.

Types of sofas depending on the ability to transform

Sofas are folding and not folding.

This type of sofa contains a transformation mechanism in the design, which is located inside the sofa body. There are more than a dozen sofa folding mechanisms. You can read more about all the mechanisms of transformation

When the sofa is folded, the mechanism is not visible. The mechanism allows you to convert the dimensions of the sofa. Usually folding sofas are needed to organize a place to sleep. Folding sofas can be both angular and straight.

• Advantages of folding sofas the possibility of transformation increases the functionality of the sofa - a sofa during the day, a bed at night. Pull-out sofas can contain additional drawers for linen hidden inside the sofa
• The lack of pull-out sofas associated with the reliability of the mechanism itself and the frame of the sofa. If the transformation of the sofa is frequent, then its wear increases. You need to carefully choose a reliable mechanism and a high-quality sofa frame when buying it.

Sofas are not folding

From the name it follows that this type of sofa cannot be converted into anything. Typically, these models are used to organize seating. Non-folding sofas can be used in pairs and or together with armchairs, creating a seating area, for example, around a coffee table in the living room. Normally, such a sofa will work in your kitchen or dining room. If the area allows, then you can use it in the hallway

• Advantages of non-folding sofas: compact size, low price
• Disadvantages of non-folding sofas: weak, limited functionality

Conclusion: if you need a multifunctional assistant, as in advertising all in one bottle, then you need a folding sofa. If the functions are more modest - just sit, then you can save a lot by buying a non-folding sofa.

Types of sofas depending on the type of filler

On this basis, two main groups can be distinguished.

Sofas filled with spring blocks

In such sofas, the filler is a structure made on the basis of metal springs. The springs can be connected in blocks or independent. Also, the spring block can have a common metal frame. This type of sofa is good for sleeping. Spring blocks have a long service life and are comfortable to use.

Sofas with filler without springs

As a filler without spring sofas can be:

• foam rubber
• PPU - polyurethane foam
• latex
• polystyrene balls

Conclusion: the choice of filler type depends on the functional purpose of the sofa. For sleep, it is better to use sofas based on spring blocks or with latex filler. If you want to save a lot, foam rubber will help you, but then the sofa will have to be changed very quickly. PPU occupies a middle position. It will do a good job of solving problems - a sofa for sleeping and for sitting.

There are a lot of upholstery. Read about the intricacies of choosing upholstery for sofas.

Fundamentally, upholstery can be divided into

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

But, I believe that among other design features of sofas, upholstery fabric plays the least importance. Because it's the easiest to replace.

General conclusion on upholstery: look at them last - the design of the sofa is more important than its appearance. The choice of upholstery type depends on the purpose of the sofa.

Look at this sofa and think about where it can be used. After a short evaluation, it turns out that there are not so many possibilities for using it.

You can find a classification by purpose, which is based on the types of premises in which the sofa will be used.

What will we get as a result

• Living room sofa
• Bedroom sofa
• Sofa for kitchen, dining room
• Sofa for children
• Sofa in the hallway
• Sofa in the office or library
• Sofa for loggia and balcony

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

Therefore, I would single out three key groups of sofas by purpose

• Seating sofa
• Sleeping sofa
• Sofa for sitting and sleeping

Conclusion on the purpose of the sofa: look at the functions that the sofa will solve in your particular case and choose based on this understanding. Do not rush to the marketing tricks of sellers - like This sofa for the living room - buy it and you will be happy. And you want to eat and sleep on it, and in this example there will be happiness, but the seller who "sold" you an unnecessary sofa.

Video - types of sofas, what to look for when choosing

Finally, I offer a short video clip. Everything that I have already told above once again for consolidation. Only now it is already "video language".

That's probably all. I hope my findings help you.

• cannot be moved close to the wall - there should be 20–30 centimeters left for free play when unfolding;
• an uneven sleeping place is obtained due to a clear separation of soft surfaces in the middle;
• transformation requires some effort.

"Eurobook", "Tick-tock", "Pantograph"

An equally popular model on the market is the eurobook sofa. He has a very simple way of unfolding: the seat is pushed forward, and the backrest fits into the vacated space.

In the "Tick-Tock" model, the transformation takes place on the weight along the trajectory of a semicircle on springs, that is, it is not necessary to carry the retractable block along the floor. This makes such a mechanism more attractive, and the model is sometimes called the "Walking Eurobook".

The advantages of sofas include:

• reliable mechanism;
• ease of unfolding;
• spacious inner drawer;
• flat bed;
• choice of sizes.

Of the shortcomings, a deep seat can be noted, which may not always be convenient. But this problem is easily solved with the help of sofa cushions.

"Accordion"

This type of transformation of upholstered furniture has firmly won the sympathy of consumers. This can be explained by the increased reliability of the design and the ease of turning the sofa into a bed. To unfold it, you need to lift the seat and pull it towards you. At the same time, the backrest, consisting of two parts, moves forward, and all the elements are laid out like an accordion in one plane.

This is a stable and easy-to-use model, but it has one significant drawback - there is no box for linen.

Withdrawable or "Telescope"

The layout mechanism of the structure is very convenient. First, the main seat of the sofa rolls out to the stop. At the same time, the headrest of the bed extends from behind the back. An additional seat or lumbar soft part is placed in the resulting niche between the two sections of the sofa.

"Telescopes" when folded are very compact, so they can be used even in small spaces. After the transformation, a fairly wide and comfortable bed is obtained.

The disadvantages include the small height of the bed and the fact that the movable mechanism can damage the floor covering.

Folding bed - French type, American (sedaflex) and Belgian

In sofas of this type, the bed is pulled out from under the seat, and then the sections are unfolded and placed on supports or legs.

French - sections are folded three times under the seat. To expand the structure, you must first remove the top cushions. Not very suitable for frequent use, as the mechanism wears out quickly.

American (sedaflex) - unlike the previous model, it has two sections and is completed with a thicker mattress. When the sofa is laid out, the low back is lowered and becomes part of the bed. Reinforced mechanism allows you to use it as an everyday place to sleep.

Belgian - can have both two and three additions. The filling and height of the mattress depends on this.

Dolphin and Kangaroo

The design of furniture with a durable reliable mechanism "Dolphin" is simple and convenient. To expand the sofa, you need to pull out a special block from under the seat, and then remove the second part of the structure from it upwards and towards yourself.

Experts consider this mechanism the most durable of all types. They are often equipped with corner models. They have a spacious and flat place to sleep, and a box for storing bed linen is installed in the side part.

The mechanism "Kangaroo" differs from the "Dolphin" in the ability to create upholstered furniture with higher legs.

"Conrad"

A sofa with such a folding mechanism is considered the most comfortable for sleeping. The design has the ability to use spring blocks. The mattress is close in parameters to orthopedic, which improves the quality of night rest.

It is not difficult to lay out such a sofa: the part located under the seat is pulled forward, and with it the rest of the sections. A distinctive feature and an undoubted plus of the sofa with the Konrad mechanism is its compactness when folded and the ability to turn into a comfortable bed.

"Lit" or "Elf"

If you need to get a small place to sleep, then you should pay attention to compact models with the Lit or Elf mechanism. When unfolding, it will be enough to lower the adjustable armrest, and the sofa will turn into a comfortable single bed. In this case, the back does not move, and the seat becomes a sleeping place.

"Puma"

The Puma design differs from other models in that it does not touch the floor when unfolded. The mechanism is equipped with a special spring system that allows you to reduce the force during transformation: you need to grab the front edge of the seat, push it up and easily pull it towards you. The middle part of the bed gently rises from the inner space and takes its position.

The designs are very durable, they can be both straight and angular, while the latter have a box for linen.

With unfolding on the floor

This is the most budgetary model of all transformation mechanisms. Two sections of the bed are laid out directly on the floor, as they do not have supports. When folded, they are inside the case. For daily use, this type is not very comfortable. It is better to use it as a guest option.

"Spartacus"

The mechanism "Spartacus" resembles the "French cot", but has a welded grille, which strengthens the entire structure. Therefore, such models can be used for everyday use. The inconveniences are the same as in all folding beds: in order to unfold, you must first remove the pillows, and there is no box for storing linen.

"Recliner"

The Recliner sofa layout mechanism is equipped with a special system that allows you to change the angle of the backrest, and a footrest. Such models are high-tech, often have vibration massage systems and remote control using a remote control.

The sofa is designed taking into account the anatomical features of a person, so it is convenient to relax on it by adjusting the position of the back and stand. The disadvantages include the high cost and the impossibility of a full-fledged layout to get a bed.

Transformer

Models "Transformer" have a swivel type of unfolding, they look stylish and modern. Turning such a sofa into a bed is very simple: one part rolls back at an angle of 90 degrees and moves back. It turns out a spacious place to sleep.

For convenient unfolding, the sofa is equipped with rubberized wheels, so moving the swivel part is not difficult. The mobile module can also be moved in the opposite direction. Some models have a fold down back and all have two large storage drawers.

"Caravan" and "Daytona"

"Caravan" allows you to transform a sofa into a bed due to a complex metal structure. The main plus is that it unfolds in just one movement, and in its normal state it takes up little space. This makes it possible to install such models in small spaces. They fit especially well in the interior of the children's room.

"Daytona" - the design of a new generation of double decomposition. To turn into a bed, you need to pull the backrest, which falls and wraps under the bed. It is very convenient that you do not need to remove the pillows during the transformation. Strength and durability is ensured by a metal welded frame and elastic straps. Great for daily use.

"Saber"

Refers to roll-out, but the design of the "Saber" is more complicated than that of similar models. The seat moves forward if the backrest is moved forward towards you. At the same time, the backrest and headrest tip over and lie on the spacious inner box. It turns out a bed on which you can sleep comfortably.

What to look for when choosing a sofa

When choosing, it is necessary to inspect the mechanism, ask the seller in detail about the pros and cons of various modifications. The service life of new furniture will depend on the correct selection of the design.

You can draw and take with you a plan of the room indicating the dimensions, so as not to be mistaken with the dimensions and accurately calculate how the model you like will be placed, whether there is enough space for unfolding.

It is worth clarifying information about the filler. Be sure to independently assemble and disassemble the sleeping system and make sure that the transformation is convenient.

Block filler

Manufacturers use a variety of materials to fill the soft parts of furniture: pillows, backs, seats, armrests.

1. Spring blocks - provide additional comfort for the body during sleep, there are three types: dependent, "snake", independent.
2. Polyurethane foam (PPU) or foam rubber - highly elastic and inexpensive, environmentally friendly, has good elasticity.
3. Felt and padded jacket - natural materials, the first is obtained from sheep and goat wool, the second - from cotton wool. Felt acts as a protective layer for polyurethane foam and spring blocks, while their surface becomes more resistant to wear. The padded jacket is laid between layers of filler for increased comfort.
4. Sintepon is an inexpensive and high-quality artificial filler that gives furniture softness, elasticity, is not susceptible to the formation of fungus, but does not hold its shape well.
5. Hollofiber - looks like fluffy balls of different sizes, made from polyester fibers, quickly restores its original shape, warm and soft;
6. Holcon (strutoplast) - elastic and warm, environmentally friendly, does not absorb moisture and odors.
7. Periotek is a modern non-woven material consisting of polyester fibers, durable, resilient, breathable, fireproof.
8. Struttofiber - wear-resistant, elastic.
9. Latex is a natural material used in the manufacture of expensive models of upholstered furniture, has increased elasticity, is non-toxic, quickly restores its original shape, does not cause allergies, and has a long service life.

For sleep, it is preferable to choose models with spring blocks. They will give the body the greatest relaxation and proper rest. The main advantage of such systems is durability and strength.

It is important to understand the features of the device of various models before buying and choose the most suitable one depending on the purpose and frequency of use. Experts do not advise buying the cheapest options, because the quality will be low, and the service life will be short.

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 will not 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"

When 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 backrest, 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 for unfolding it 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 previously 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 "Accordion" sofa in its compact size when folded. But we must not forget that to unfold the sofa, you 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.

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.

Purchasing a new sofa is a major purchase that raises many questions and doubts. As with the choice of most pieces of furniture, the buyer wants to find a model that is equally comfortable, practical and stylish in appearance. The best way to choose the most comfortable sofa is to visit a furniture showroom and feel like the owner of a particular model.

• Some models of sofas are designed to perform only one function - they serve as a place to relax in a sitting position. These are the so-called guest sofas.
• Another variety are models that transform into a bed. When buying such a model, be sure to familiarize yourself with the mechanism of its operation to make sure that it is suitable for the conditions in which it will be operated.

Varieties

The folding mechanism of the sofa makes it easy and simple to turn it into a bed. Currently, there are many such options. However, before buying a sofa with any of the transformation mechanisms, you need to carefully study their properties, as well as find out what material they are made of. These characteristics will allow you to judge how long-term and comfortable the operation of the sofa will be. In the case of complex mechanical devices, the choice of transformation mechanisms made of reliable steel grades will be the most preferable option.

According to the type of layout, the sofa can be:

1. Turning, which is also called a transforming sofa or modular;
2. Folding, this category includes both folding sofas (French or American) and “Eurobook” sofas;
3. Withdrawable, which can be straight or angular;
4. with lifting mechanism, which happens on hinges, springs or can be carried out using a gas shock absorber system;
5. With walking mechanism, which is also called stepping; such designs include tick-tock, tango, and pantograph sofas, which are variants of the improved Eurobook model;
6. "Scissors"- most often these are corner structures;
7. "Butterfly", which is also called the "versailles" mechanism.

"Dolphin"

One of the most convenient and frequently purchased sofa layout mechanisms. The base of this sofa is on a retractable platform. While the design is in the form of a sofa, the platform is invisible, because it is hidden under its seat. In order to unfold the sofa, you need to roll out this platform and lift its edge slightly up by pulling on the special loops. This will ensure that the surface of the platform is leveled at the same height as the seat. The resulting bed has an elastic base and a comfortable height.

Folding such a model is very simple: you need to pull up, holding the belt of the retractable base, it will rise and the mechanism will take it inside the roll-out platform. The platform itself then slides down under the seat. Such a mechanism is very reliable, allows you to get a comfortable resting place for two people, suitable for use every day.

Sliding sofas "dolphin" can be either straight or corner. In the latter case, they are supplied with a box for things located under the ottoman.

"Eurobook"

This layout is also known as "alternative". This folding model, in fact, does not have any mechanism that ensures its transformation, being an example of simplicity and reliability. The movement of parts of the structure occurs due to the rollers that move in the grooves of the base. This option is simple and suitable for long-term use.

To turn the eurobook into a bed, you need to remove the pillows and push the seat forward. Then it remains to lower the section, which was the back of the sofa, and you get a classic bed. To return the sofa to its original position, you need to do the same operations in reverse order: first, the backrest rises to its original position, and then the roll-out base moves towards it.

Under the seat there is always a compartment for storing bed linen, which is very convenient for the owners. Such models can be angular or straight type.

"Pantograph"

The mechanism called "pantograph" (also known as "Tick-tock" or "Tango") is an updated and improved version of the well-known "Eurobook". To turn this model into a bed, as in the case of the Eurobook mechanism, you need to push the seat forward. However, to do this, the seat must first be lifted up slightly by pulling on the hinges. Thanks to the folding mechanism, it will automatically take the desired position. The extended seat is placed on the floor and then the back of the sofa is lowered.

It turns out a wide and elastic bed on a spring block. The reverse transformation can be done by putting the backrest in the normal position, and then raising the seat and moving it close to the backrest. The mechanism is designed for daily use. Sofas of this type are suitable for those who have high pile carpets at home, because the transformation takes place without moving the furniture directly on the floor.

In the case when the model with the pantograph mechanism is angular, it has a box for storing bedding.

"Puma"

A very simple and softly working spring mechanism of sofa expansion, which in terms of smoothness of movement really resembles the steps of a wild cat, after which it is named. During the transformation, the seat of such a model rises and, as it were, takes a step forward. In order to do this, it is enough to pull on the loop mounted at the bottom of the seat. At the same time, an additional platform hidden there will move out from the depths of the sofa, which, having taken the vacant seat, will transform the sofa into a full-fledged bed. This transformation occurs through a single movement gently and smoothly, which is facilitated by properly selected springs, equipped with a synchronizer.

Folding this model is also very simple. The folding process is carried out in one movement, for this the same sewn-in loop is used. Raising the front of the bed with it, you need to make a slight push back to the back of the sofa, and the built-in mechanism will lower both platforms into place. This mechanism is ideal for everyday use.

A straight “puma” sofa does not allow to have a place for storing linen in the design, however, in corner modifications equipped with an ottoman, such a compartment is present.

"Conrad"

This type of transformation is also called high-rise roll-out.

The mechanism consists of three fragments, folded compactly packed in the back of the sofa. The outermost part of the bed is a frame structure, the middle part is a platform, completely standing on the floor and serving as an assembled seat, the head part is in the back.

When laying out such a sofa, you do not need to remove soft pillows, they will not interfere with pushing out of the depths of the structure and installing three retractable parts. The frame part is pulled out to the level of the legs first, it pulls the seat behind it, which, moving, gives impetus to the extension of the head of the bed. Special rollers with brackets moving along hardwood guides and a well-oiled mechanism allow such a transformation to be carried out without much effort. In order to fold the “konrad”, you need to lift the frame part by the built-in loop and push it towards the back.

However, with everyday use, such a model may not seem very convenient in the layout. This will be especially problematic for a woman or a child, since the retractable parts are of considerable weight.

The advantage of this model is its compact and elegant appearance, the creation of a comfortable and reliable bed without kinks and the presence of a box for storing linen built into the back.

Since the Konrad mechanisms are not produced in the Russian Federation, this affects their cost: sofas with similar components have a fairly high price tag.

Transformer

This is a sofa with a swivel transformation mechanism, which is also called "scissors". Usually these are large corner sofas with an ottoman. Outwardly, they are not too distinguishable from corner sofas of other designs, but if you look closely, it becomes clear that the ottoman of such a model has a slightly longer length than usual. With the pillows removed, its length will be about 190 cm, thus this part of the structure can simultaneously serve as a sleeping place without any additional transformations.

If you move the main part of the seat at an angle of 90 degrees and move it close to the ottoman, you can get a full-fledged sleeping place, already designed for two people. For ease of movement on the floor, the sofa-transformer is equipped with rubberized wheels. For reliable fixation, the wheels are equipped with brakes, which are installed as needed.

You can move the seat not only close to the ottoman, but also in the opposite direction, getting a U-shaped design. For some models of transformers, the back is additionally lowered, so the buyer can choose exactly the option that seems optimal to him. Each of these models has two spacious storage drawers and is an alternative to the usual roll-out sofas.

"Accordion"

The accordion folding mechanism is strong and durable, when unfolded, it turns the sofa into a full-fledged bed. It works on the principle of an accordion, for which it received its name.

When assembled, it has a double-fold back, which, when unfolded, straightens and creates the basis of a bed. In order to expand the "accordion", the seat is lifted slightly up (until it clicks), then the mechanism begins to move forward, stretching the back folded in half. For stability and reliability, such models are usually equipped with armrests.

Assembling the "accordion" takes place without much effort, but requires some skills. In order to start the assembly mechanism, you need to lift up the extreme part of the structure and push it towards the back: the "accordion" will curl up.

This model is usually straight, has a box for storing linen, when folded it is very compact and takes up a minimum of space. Such models are designed for daily layouts.

"French" folding bed

The transformation mechanism called the "French" clamshell has a second name: such structures are called "mixotual". This is the so-called metal frame mechanism. It consists of steel tubes of various thicknesses (in domestic designs it is 1.5 mm, in imported ones - 0.8 mm), an awning made of durable fabric (most often it is polypropylene) and equipped with transverse support strips - "armor" (made bent plywood) and equipped with a polyurethane foam mattress, which is in a fabric cover.

When laying out and folding, the mattress remains inside the structure, since it does not have its own frame. To open the "mixotual" almost no physical effort is required, for a start it is enough to pull up and forward the very frame of the mechanism, which is also the edge of the seat of the sofa. Then the whole mechanism must be lifted up and “rolled out” forward, like a regular clamshell. At the same time, sections folded into each other will straighten out, each of which is equipped with folding legs-supports made of metal semicircular tubes. Thus, a sleeping place is laid out, designed for a weight of about two hundred kilograms and dimensions of 185 * 145 cm. Sofa cushions are removed before transformation.

When assembling, the outermost segment of the structure first rises, which is “wrapped” onto the middle one, and then both of them are placed on the base of the sofa. The mattress is not removed, but bed linen, pillows and blankets must be removed to avoid damage to the mechanism.

"French folding bed" is a convenient and easy-to-transform mechanism, designed for use from time to time, the so-called guest version of the bed. In many ways, the service life of this model depends on the quality of the steel fittings located at its base, the reliability of the laths and the density of the awning.

"Sedaflex"

This mechanism has another name - it is often called the "American" clamshell.

This design is copyrighted by Sedac, hence the name "sedaflex". It is an improved version of the “mixotual”, while the mechanism is not divided into three, but only into two parts. Another innovation is the filling of the mattress with a spring block, which increases the comfort and stability of the bed. Thicker tube-legs, which have a thickness of 3 mm, also contribute to reliability.

Another advantage of the "American" is the fact that sofa cushions do not need to be removed before transformation. The design is designed in such a way that when laying out the sofa, the pillows turn over, ending up on the floor, and thereby increase stability and save time and space for the owners. Also, as an advantage of the "sedaflex", we can mention the fact that it was decided to replace the reiki-lats in it with elastic belts.

The transformation of the "American clamshell" is similar to the transformation of the "mixotual", both models are laid out forward with the help of physical effort. By pulling the edge of the seat of the folded sofa, it is lifted up a little and the entire structure is laid out with a fixed mattress.

The dimensions of the Sedaflex are somewhat larger than those of its French counterpart, which contributes to the greater popularity of this particular model.

A box for storing linen is not provided in any of them, since the entire internal space in the sofa is occupied by the mechanism itself. However, if the clamshell models come with an attached section, which can be located on either side, then in this section it is possible to place linen for storage.

"Telescope"

This mechanism got its name due to the resemblance to the unfolding of a telescope. When it is implemented, the transformation occurs as follows: first, pulling on the mounted hinges, the lower tier of the structure, previously hidden under the seat, is rolled out. This will be the basis for the bed, or rather, the part where the legs of the sleeper will be located. When extended, it will pull the platform behind it, which will become the middle part of the base of the bed.

To assemble the structure, the spring block is first returned to its original place, then the lower part of the sofa is pushed in. It is worth noting that in the first pull-out section there is a place for bed linen or clothes.

One of the disadvantages of the telescopic design is the fact that it is not suitable for a large sofa. First of all, these are two- or three-seat sofas that are good for a nursery.

How to choose?

Any sofa, even folding, even non-folding, has similar design features that must be considered when choosing:

1. There are no standard sizes for them. The height, width and depth of such upholstered furniture vary depending on the type of sofa layout and whether it is angular, straight or modular.
2. When purchasing such furniture, you need to take into account the size of the room: the model for daily sleep should fit freely in the room in the unfolded state.
3. Types of such sofas are divided into straight and angular. The latter can have different angles: left, right or the so-called universal angle.
4. You can choose either a model for every day, or a guest option, for this you need to decide how often you need to transform the sofa into a bed.

Immediately before buying, it is advisable to visit furniture stores in order to “live” inspect various models and personally check how convenient and easy the transformation mechanisms work. At the same time, you should not stand and observe the process of unfolding the sofa by a consultant, it is better to ask the seller to show the layout principle and then do this procedure with your own hands. Only in this case, you can understand whether it will be convenient to perform such actions daily.

For every day, it is better to choose the most easy-to-transform mechanisms, such as, for example, “Eurobook”, “telescope”, “pantograph”.

The service life that a sofa will withstand without repair depends entirely on the quality of the materials from which its base, body and folding mechanism are made.

Be sure to make sure that the interior of the sofa is made of solid wood, and not chipboard or plastic, because in this case they can deform and crack. The quality and type of wood is also very important. Softwoods such as pine are cheap and are used in inexpensive sofas, but they can warp or dry out after a while, usually after five years. More expensive woods, such as kiln-dried oak, ash or beech, will make the sofa durable and keep it beautiful.

Therefore, be sure to carefully ask the consultant and carefully examine the inside of the sofa. In this case, it is worth paying attention to how the joints and joints are attached. It is important to remember that the design, in which the constituent parts will be held with screws, dowels or on special furniture pegs, will last much longer than the one whose parts are fixed to each other only with glue or fixed on simple self-tapping screws.

An important factor when buying a folding sofa, of course, is the availability of space in the apartment for its transformation. If you have limited space, but need extra beds, then instead of one huge sofa, it would be preferable to purchase two small folding sofas.

In addition, the firmness of the sofa mattress is another important factor to be taken into account when choosing a model. This largely depends on personal preference. But, as a rule, a firmer mattress will be healthier, and when using this sofa as a bed, it will make it possible to get a good night's sleep.

The next important factor is the elasticity of the sofa. It also has to do with personal preference and choice. Some people don't like bouncy sofas, and some don't. In order to evaluate the future acquisition from these positions, it is worth sitting on it even before the purchase, and it is even better to lie down.

If there are animals in the house, which, of course, will certainly be happy to lie on a brand new sofa, it is worth choose your upholstery carefully. Contaminants such as pet hair and fluff are well removed from flock and leather, but get stuck in the tapestry; on such a coating as a shinil, there are puffs left from their claws.

And finally, the weight of the sofa is another important aspect that the buyer should consider.

Let's open the secret: there are no "bad" and "good" transformation mechanisms, there is a wrong approach to choosing the right model. To understand what sofas are, to find "your" option will help a review with short illustrative videos.

When choosing the type of transformation, pay attention to how the sofa unfolds, lightness and speed, contact with the floor and the presence of a linen box. The purpose of the future sofa is also important - daily use or unfolding from time to time?

Book

A mechanism familiar to many since childhood. The transformation from sofa to bed is simple and intuitive. Time-tested folding sofas are equipped with a spacious linen compartment under the seat and have an attractive price due to the simplicity and unpretentiousness of the design.

How to decompose: the seat moves up until it clicks and then goes down. The back takes a horizontal position, forming a flat surface for sleeping and relaxing.

What is good: low price, quick unfolding method, capacious laundry box.

Things to remember: the distance from the back to the wall must be at least 10 cm, for unfolding it is necessary to make an effort.

Eurobook

Reliable and easy to use sofa transformation mechanism. Due to the absence of loops at the junction, the sleeping surface is smooth and comfortable. The bed is located along the sofa, which is ideal for narrow spaces. There is no need to think about how to unfold or fold the "Eurobook" and there is no need to move it away from the wall every time - the design of the model moves forward.

How to decompose: Roll out the seat and lower the backrest - the place to rest is ready.

What is good: reliability and, there is no need to move the sofa every time it is unfolded, suitable for narrow rooms.

Things to remember: models without wheels may scratch the floor.

Pantograph

This variety has all the advantages of the Eurobook, and even more. Rising sofas are not equipped with rollers and move apart without touching the floor. The lifting mechanism pushes the seat up and it seems to step forward, leaving the flooring intact. The reverse folding mechanism is also effortless.

How to decompose: pull the seat up and towards you and lower the backrest.

What is good: does not interact with the floor, equipped with a linen compartment, no need to move when unfolding.

Things to remember: unfolding requires more effort than in the "Eurobook".

eurosofa

Folding systems on a metal frame are reliable and durable. Perfect for active daily use, they will easily endure rearrangements and moving.

How to decompose: press from top to bottom on the edge of the back - gently lowering, it will take a horizontal position. To reverse the transformation, pull the backrest frame up.

What is good: has a metal frame at the base, does not require moving the sofa away from the wall.

Things to remember:the only disadvantage of such systems is the relatively high cost.

Dolphin

Sofa, which includes a mechanism"dolphin" , unfolds with particular ease and speed. The device was named after the animal of the same name due to the similarity of movements.

As a rule, it is found in corner sofas. The bed frame is held by special brackets at the level of the main part of the sofa. Due to its compactness, this model will successfully fit into the interior of a small room, and a spacious laundry box under the corner part will help to hide home textiles and household items.

How to decompose: slide the frame out from under the seat and pull it up.

puma

Like a cat, laid out as quietly and accurately as possible. No scratches from the legs or dented tracks from the wheels - even the most demanding flooring will not suffer during daily unfolding. When transforming, minimal effort is needed: pull the seat up a little, and then the mechanism will do all the work.

How to decompose: pull the bed towards you by the seat, and the part below will appear behind it.

What is good:noiselessness and respect for the floor covering, it is easy to unfold.

Things to remember: straight models do not have a laundry box. For corner models, it is located behind the ottoman.

Accordion

It got its name due to the similarity of unfolding with the movement of the bellows of a musical instrument. The bed is flat and wide, without tangible joints. The model belongs to the category of sliding sofas and noticeably eats up space in length, choose it if the space allows such room for manipulation.

How to decompose: pull the loop and the seat will move forward, and the back will turn around and split into two parts.

What is good: ease of unfolding.

Things to remember: requires a lot of space for unfolding, so do not place a table or other furniture in front of the seat. The mechanism needs to be looked after and regularly lubricated.

Caravan

The mechanism of unfolding on a metal frame, reliable and durable. Due to the forward transformation, it organizes a wide berth (similar to a double bed) with a relatively small size of the “caravan” sofa.

How to decompose: pull the seat up - it will begin to describe an arc in the air. At the same time, two additional platforms will appear from under the base one after the other. When the seat is lowered onto the supports, the three functional parts form a flat sleeping surface.

What is good: design reliability and ease of transformation.

Things to remember: since the place under the “caravan” seat is occupied by additional platforms, sofas of this type do not have a linen box.

French cot

French cot or"sedaflex" - light and compact European guest solution. Due to the design features, the model unfolds much longer than the “cougar” or “eurobook”, it does not have a linen box, and also such a sofa is not suitable for daily unfolding. If you need an option for frequent use, look for a French clamshell model with a wooden frame in the support base instead of fabric - this option is more beneficial for the spine.

How to decompose:lift the top seat cushion and pull the legs forward - the sleeper, folded like an accordion, is hidden under the seat.

What is good: lightness and structural strength.

Things to remember: there is no drawer for linen, the bed is too soft (not recommended for daily sleep), sofas with a forward-folding mechanism do not always fit well into narrow spaces.

Rich

Mechanism "Rich" or"Spartacus" - American bifold bed. In its design - a metal frame and a welded lattice, reliable and durable. The system is suitable for both guest and daily use. The main feature of the mechanism is the ability to “remove” the seat under the bed, which automatically facilitates the task of transformation.

How to decompose:lift the seat and pull the system towards you - the folded double bed will appear from under the base.

What is good: easy to fold, reliable and durable.

Things to remember: The design does not include linens.
