Types of sliding sofas. Mechanisms for transforming sofas: what are the types, which mechanism is better

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

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

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

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

Sofas without transformation mechanisms

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

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

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

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

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

The mechanism of transformation of the sofa "Book"

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

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

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

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

Sofa "Book" often contains a section for bedding inside

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

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

The mechanism of transformation of the sofa "Tango"

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

Sofas "Tango" have a section for storing the bed

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

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

The mechanism of transformation of the sofa "Eurobook"

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

Advantages: ease of converting the sofa into a bed, the simplicity of the mechanism itself - read its high reliability, large and flat 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 with 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.

Sofa transformation mechanisms - video review

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

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

The sofa, as you know, is an integral part of any interior and, as a rule, one of the most important elements in the apartment.

At the same time, the search for the very sofa that will delight you and your loved ones, as well as be able to fit the whole family and fit amazingly into your particular interior is quite difficult. You can Buy a sofa in Moscow of any design, but first you should decide what you need.

In our today's article, we will try to understand in as much detail as possible how not to make a mistake with the choice, what types of sofas exist and how to find the right option for you?

What are the types of sofas

There are a huge number of sofas on the market with a different set of characteristics, which we will dwell on in more detail. It should be said that the choice of a sofa should be made consciously, weighing all the pros and cons, as well as starting from the purpose for which you need it.

After all, you must admit that if you are part of a large family that often comes to visit you and stays for a couple of days, you can’t do without a folding mechanism, and if you just spend a couple of hours a week on the sofa, then you don’t need such a mechanism. not worth paying for it. Now let's take a closer look at the types of sofas.

Transformation mechanism. Whichever sofa you choose, each of them can be equipped with a folding mechanism. And by the way, such mechanisms are also different in the way the sofas are laid out:

• “Book” (the most traditional mechanism that is familiar to everyone, in order to bring this sofa to a horizontal position, you need to raise the seat up until it clicks, and the back will automatically lower, creating a sleeping place, a certain disadvantage of such a mechanism is that you cannot put the sofa close to the wall)
• "Eurobook" (in this case, in order to bring the sofa to a horizontal position, it is necessary to push the seat forward and tilt the back into the vacated space, a significant advantage of this model is the ease of transformation and soft back)
• “click-clack” (this mechanism is also similar in unfolding to a “book”, but in addition to this, it has the function of fixing the back and the ability to install it in several positions, such a nuance will allow you to choose exactly the angle of inclination at which it will be convenient to relax, but in this case, the sofa will also need to be installed at a distance from the wall)
• "dolphin" (this model is most often found in corner sofas, in this case the pillow is pulled out from under the seat and pulled up with a special loop, being installed flush with the main seat, this is an extremely popular mechanism that also has a linen box)
• “French folding bed” (a mattress is tripled under the seat in the sofa, which is subsequently unfolded, this is a very comfortable and compact model, though it is hardly suitable for everyday use)
• "Accordion" (in order to expand the sofa, it is necessary to push the seat forward and expand the double-folded back, such a sofa has large dimensions and transforms into a full-fledged and comfortable sleeping place, although the appearance of such models leaves much to be desired and over time, ugly creases remain on the mattress)

In this article, we will briefly and informatively talk about the most common sofa transformation mechanisms that are presented on our website. Our goal is to help you quickly navigate these not always clear names and find the right option for you.

To do this, we will consider sofas from the point of view of the consumer, and these are just 2 main criteria:

1. convenience of daily unfolding of the sofa;

And now let's list the most common sofa mechanisms:

1. Book;
2. Tick-tock;
3. American folding bed (Sedaflex);
4. French folding bed (Mixotoile);
5. "mechanism in 3 additions";
6. Spartacus.

Withdrawable mechanisms:

7. Eurobook (Eurosofa);
8. Dolphin;
9. Kangaroo;
10. Konrad (telescope).

"Book". The principle of using this mechanism is simple: you need to raise the seat until it clicks, and then lower it - while the backrest also drops. "Book" - the simplest mechanism in terms of use - it is easy to lay out and difficult to break.

Pros: the sleeping place is located along, and not across the wall. Such a folding mechanism is perfect for small spaces, because it does not take up much space, both assembled and disassembled.
Minuses: when laying out the sofa, it must be moved away from the wall, which is quite inconvenient for daily use. There is a risk of damaging the floors if you do not lift the sofa. In the place where the back and base are connected, a tubercle or notch may form, which interferes with comfortable sleep and limits space.

"American folding bed" or Sedaflex. Here the bed consists of two sections. To unfold the sofa, you need to remove all the cushions, pull the seat up and towards you by the special handle and unfold the sections until they rest on the supports. The sofa unfolds in two stages: first, the first section opens, and the second one unfolds behind it. Maximum load - 240 kg.

Pros: reliable transformation mechanism, made of high-quality wear-resistant materials. Sedaflex sleeper is flat without creases and bends. This sofa has a reinforced metal frame and mesh, which provide high structural rigidity and comfortable sleep. Also, this model allows you to use high-quality 12-cm mattresses.
Minuses: there is no linen box and there may be seams on the sleeping surface.

"French cot" (Mixotoile). This transformation mechanism is similar to an American clamshell, but unlike its “American version”, it consists of three parts, and otherwise, the folding principle is absolutely identical. The "French folding bed" has a fully metal frame, to which a high-density canvas awning is attached with the help of springs. Under the tarpaulin there are special wooden slats that give the sofa an orthopedic effect. The maximum load on the mechanism is 180 kg.

Pros: soft bed, equipped with a 50 cm thick mattress.
Minuses: uneven sleeping place, does not have a linen box.

"Spartacus". Structurally, the mechanism is identical to the "French clamshell" - it also consists of three sections and unfolds in a similar way. However, there is a significant difference that can affect the purchase decision. "Spartak" is equipped with a reinforced metal mesh, which allows it to withstand high loads, and you can use the sofa for daily sleep. Maximum load up to 240 kg.

Pros: Due to the reinforced frame, the model is highly durable, and therefore its durability indicators are higher. Has a spacious bed.
Minuses: like all clamshells, the Spartak mechanism has a not very aesthetic side view when unfolded. Due to the improved quality, the mechanism will cost more than the "clamshells".

"Tick-tock." The main advantage of tick-tock is its ease of use. The mechanism unfolds in no time: pull the seat up and forward, and then lower the back to the vacant seat. You can even do it with one hand! In this case, the maximum load on the bed is 240 kg.

Pros: the mechanism provides a spacious sleeping place and does not touch the floor covering when unfolding.
Minuses: when folded, the sofa has a fairly wide seat, which is not always convenient. If the mechanism breaks, the repair will cost quite a large amount.

Mechanism "in three additions" and the "French clamshell" mechanism are essentially the same. They fit the same and look the same. But many manufacturers share them, explaining that they use different materials for manufacturing. Therefore, when choosing a sofa with such a mechanism, specify what it is made of in order to avoid surprises later. The maximum load per bed is 180 kg.

Pros: soft and wide bed.
Minuses: there is no box for linen, the bed has bumps, and when unfolded, the sofa does not look very aesthetically pleasing.

Pull-out mechanisms.

IMPORTANT! Pay attention to the rollers and supports on the "roll-out" sofas. They must be made of soft materials - this will ensure the safety of your floor!

"Eurobook"- This is an improved version of the "book" mechanism. It is worth saying that this is one of the most popular vacant mechanisms on the market. The model consists of two parts: a back and a seat, and also has a spacious laundry box. To expand the sofa, you need to remove the back cushions, roll the seat towards you until it stops, and lower the back back to the vacant seat.
All parts of a sofa with such a mechanism should fit snugly against each other, but if cracks appear in the sofa, this indicates a low quality of the product. Maximum load is 240 kg.

Pros: such a sofa looks good both against the wall and in the middle of the room (it can be used for zoning the room, if space permits). "Eurobook" provides a full-fledged spacious bed. Minuses: when extended, the seat "rides" on the floor and may damage the floor covering.

"Dolphin"- perhaps one of the most convenient and common mechanisms on the market. It is very easy to unfold: just roll out the additional section from under the seat and pull the fabric handle towards you - the sofa is ready for use. The maximum load on the mechanism is 200 kg.

Pros: Sturdy construction guaranteeing the durability of the mechanism. The sofa provides a spacious sleeping place, there is a capacious linen box.
Minuses: when unfolded, there is a barely noticeable joint between the seat and the roll-out section.

"Kangaroo". This mechanism is very similar to the previous one in terms of the type of unfolding. Its only difference from the "dolphin" is a higher bed.

Pros: solid construction, a wide bed, the presence of a large linen box.
Minuses: in the unfolded state there is a joint between the seat and the roll-out section.

"Konrad" (telescope). This mechanism consists of three sections. For unfolding, it is necessary to pull the lower roll-out part (the first section), behind which all the others will extend. After you have put forward all the sections, you need to take the top of the first section and unfold it, laying it on the second. IMPORTANT! "Telescope" is very compact compared to other mechanisms, and also has an orthopedic grille. The maximum load per bed is 180 kg.

Pros: Compact when folded and space when unfolded.
Minuses: hard to move - the mechanism and the sofa are heavy.

1. If funds allow, choose a hardwood sofa frame (oak, beech, birch).
2. Carefully inspect the mechanism, it should have a manufacturer's mark on it. Unfold and fold the sofa, while all the positions of the back and armrests indicated for the model should work.
3. If you are looking for a sofa "for a long time", then it is better to choose a model with an independent spring block, it is much more durable than the usual "snake", dependent spring block or simple polyurethane foam (PPU).
4. When buying a sofa with a mechanism on a wooden base, give preference to oak, beech or birch - their wear resistance is much higher than that of other types of wood.
5. Remember, the length of the bed depends on the design of the sofa. If you are tall, pay attention to Eurobook type sofas or sofas with roll-out mechanisms. Their kinematics allows you to make a bed longer than two meters.

What elements make up the design of sofas

How sofas differ in design and purpose

What are the designs of sofas for unfolding

Usually a sofa is purchased for more than one year, therefore, it is necessary to approach its choice responsibly. New upholstered furniture should fully meet its purpose, be comfortable for the whole family and be in harmony with the interior. That is why, choosing this kind of furniture, you should pay close attention to the design of sofas.

What structural elements are sofas made of

As a rule, when purchasing a sofa, we first of all pay attention to its appearance, namely, upholstery fabric, color, shape, etc. However, when choosing a specific model, it is important to study the design of this piece of furniture, because its quality characteristics depends on how long the sofa will serve you.

What is the design of the sofa?

Armrest. Usually it is made of wood, chipboard, MDF, metal. The armrest can be upholstered in fabric or leather. When purchasing a sofa, give preference to models whose armrests are made of wear-resistant materials (wood, metal, MDF, leather).

Upholstery. It can be a special fabric, leather.

A layer of synthetic winterizer or batting.

Filler- foam rubber for furniture.

Polyurethane foam pad(PPU), which is necessary for increased wear resistance and uniform weight distribution. Such inserts give the sofa orthopedic properties.

spring block- This is the main shock-absorbing part of the sofa design.

Burlap or felt. These materials smooth out the friction of metal on plywood, thereby preventing the appearance of unpleasant sounds.

fibreboard(Fibreboard) - is the base of the sofa mattress.

sofa frame. It can be made of wood, metal or chipboard (chipboard). The frame is a structure that bears the main operational load and determines the shape of the sofa. Therefore, when choosing, pay special attention to the quality characteristics of the tree from which the frame is made. The presence of knots is undesirable, since in these places the wood can burst.

Interlining.

Roller rail. It can be located at the bottom of the box and be made of both wood and metal.

Box or niche designed for bedding.

Extendable part, which is used during the transformation.

Types of sofas by design, purpose, size and number of seats

Direct models are classics. Their main advantage is that the size of the sofa can be selected depending on the area of ​​​​the room. They come with or without armrests, transforming or stationary.

corner sofas are well known and in demand among buyers. They are comfortable and functional, can be installed in various rooms, for example, in the kitchen.

When choosing this model, the question may arise about what to do if you need to rearrange the sofa to the other side of the room, how to properly disassemble the corner sofa. The design of many models for such a case suggests the possibility of reinstalling its corner part. The sides of such a sofa can be either different or the same length.

Modular pieces of furniture can be collapsible and, like a designer, be transformed at the request of their owners. This type of sofa has such a design, thanks to which it is easily modified in accordance with the interior of the room. This advantage will save you from having to buy new furniture in case of a move. The modular sofa is perfect for rest rooms with a home theater.

Island types of sofas are initially rounded, they are most often located in the center of large rooms. Furniture of this type is able to create a unique interior. Their special form is often harmoniously complemented by other furnishings.

All types of sofas according to their purpose can be divided into:

• for the living room;

  for kitchen;

  for the hallway;

  for children.

At the same time, the types of sofa designs are different, in this regard, it is necessary to choose a specific model that will suit you exclusively. Usually the upholstery of the sofa determines its purpose.

For example, upholstered furniture, upholstered in leather or similar cheap materials, is usually intended to be placed in offices or in the kitchen.

Sofas for children's rooms in most cases are covered with colorful, rich, but quite practical fabrics, from which various stains can be easily removed.

There are compact models of sofas designed for two or three people, and large ones for five or more seats. It should be noted that there is no single standard for the size of such upholstered furniture. For example, one factory produces a two-seater sofa, the length of which is 1.6 m, while the other one will have the same length of 1.9 m.

Sofa designs according to the folding mechanism

"Book"

Sofas of this design are transformed into two positions: sitting and sleeping. In order to expand the sofa into a bed, you only need to fold its back back. When unfolding, it does not have to be moved away from the wall, because when installed, a small gap is specially left between the wall and the back.

The design of the “book” sofa consists of two frames, which are made of metal or wood, with fixed spring blocks or other soft filler. The laundry compartment is usually located at the bottom.

Advantages:

long service life;

functionality;

ease of operation;

regular use without breakage and wear.

Disadvantages:

there are only two positions - lying and sitting;

cannot be installed against a wall.

"Tango"

This model of sofas is transformed by the “click-clack” method. And it is called "tango" because the manufacturers simply want to surprise the consumer with an unusual name. Although this design is very similar to the classic "book". However, there is one difference - when laying out such a sofa, there are not only “sitting-lying” positions, but also intermediate ones. The back can be set at the level that is most convenient for you, in addition, it has a box for bedding.

Advantages:

backrest in different positions;

compact size;

after unfolding, a smooth surface is obtained.

The disadvantage is the inability to install the sofa close to the wall.

"Eurobook"

The design of the Eurobook sofa makes it easy to recognize it among the classic models: it unfolds with the help of roll-out rollers that push the seat forward. In the resulting niche fits the back of the sofa.

Advantages:

ease of transformation of the sofa into a bed;

large niche for storing various items / things;

capacity;

the strength of the sofa design.
