Types of sofas. How to choose a sofa by type. New and Traditional Sofa Folding Mechanisms Types of Sofa Folding Mechanisms

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

Types

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

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

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

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

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

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

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

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

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

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

leather models;
fabric.

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

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

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

The most fashionable colors and materials

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

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

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

How to choose?

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

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

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

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

Modern models for the hallway are performed:

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

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

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

How to care?

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

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

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

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

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

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

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

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

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

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

Transformations.
Design features of furniture.
Appointment.
Size and capacity.

Types of mechanisms

Names of sofas

Classification by purpose

All models can be divided according to their purpose:

Office furniture.
Living room furniture.
Kitchen furniture.
Hallway furniture.
Furniture for a children's room.

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

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

Equipped with a special built-in mechanism that allows you to turn each of them into a bed in a matter of seconds. The choice of this mechanism depends on the area of the room, the frequency of use, as well as on various additional advantages (ease of layout, the presence of drawers for linen, etc.). All models can be conditionally divided according to the type of mechanism into rolling out, unfolding and unfolding. Let's take a closer look at each of them.

Sofas with folding mechanism

This is a widespread and one of the oldest mechanisms. His bed is formed thanks to the back and seat. They are stacked horizontally when transformed, forming a double bed. The most popular types are "click-clack", "eurobook", "book".

"Book"

This is a very simple layout. It is necessary to raise the seat until it clicks, then lower it, after which the back takes a horizontal position. These types of folding sofas are designed for daily use. They create a high bed, and also suggest drawers designed for bed linen. These sofas are not the most reliable, as they wear out quickly enough. To expand the "book", you will need additional space. If it is located against a wall, then it will need to be moved away. Therefore, when it is best to immediately leave a distance behind the back of the sofa, so that later, when laying out, it does not have to be “carried” around the room.

"Click Clack"

Views with the "click-clack" transformation method have the same mechanism as the "book". At the same time, there is an intermediate position of the back, which allows you to remain in the “reclining-semi-sitting” position. This gives an additional advantage and makes this piece of furniture for relaxation even more comfortable. To move to the relax position, you need to raise the seat to the 1st click. Raising it to the 2nd click, you can expand the sofa completely.

"Eurobook"

Such types of folding sofas require practically no effort during the transformation. The seat is pulled forward, while the backrest fits into the free space. They are convenient, when laying out they do not require a lot of space (they can stand against the wall). Compared with the same "book" they form a wider, even bed. They also have drawers for laundry. A feature of such sofas is that they do not have such a mechanism as the "book". Thanks to this, they practically do not break. Their only drawback is that with everyday use, the seat rollers can spoil the floor surface.

Sofas with unfolding mechanism

This is quite popular, although not the most popular. Such types of sofas suggest that the bed remains inside under the seat when folded, and when transformed, it first moves forward, and then unfolds to form a bed. The most common type is a folding bed, as well as its varieties: "sedaflex", French folding bed.

French cot

This is a triple folding mechanism located under the seat cushions. Before unfolding it, it is necessary to remove the pillows, then pull out the lower part by the handle, and then gradually unfold it. His bed is a frame, which consists of three sections connected by hinges, and a mattress. These types of sofa mechanisms are widely used in models that differ in design and price. They are very small and do not affect the appearance in any way. It does not assume the daily use of furniture. Such a sofa is more suitable for guests (exceeding the permissible load and frequent use will lead to sagging of the mattress). In addition, these models do not have a place to store linen.

"Sedaflex"

Similar types of transformation of sofas resemble a French folding bed. Although they are more expensive and durable. During the layout, you need to slightly raise the mechanism, and then pull it towards you with force. This is one of the most reliable models, it is able to withstand heavy loads without changing the frame. Such designs allow you to form a rather high and wide berth, while the folded sofas are very compact. The only disadvantage of such models is the lack of storage space for linen.

Types of sofas with roll-out mechanism

This type of mechanism is becoming increasingly popular due to ease of use, high strength and spaciousness of the bed. It is very convenient to lay out such a sofa, since the berth is pulled simply forward. But when acquiring such a model, you must carefully consider all the components of the mechanism. For example, experts say that a good sofa should have closer springs, then it will last a very long time. Models with a roll-out mechanism have one characteristic drawback - a low berth that can push through and scratch the floor during transformation. Common models: "dolphin" ("kangaroo"), "accordion".

"Accordion"

Similar types of transformation of sofas are based on the “accordion” principle: in this case, the seat rises to a slight click, and the double back folded into a house stretches like an accordion, thereby forming a flat bed with a seat. Such models are very easy and quick to unfold, have covers for each of the elements and drawers for linen.

"Dolphin" ("kangaroo")

This is a mechanism that is installed more often than others in various types of corner sofas. When laying out, a platform rolls out from under the seat, which then rises, forming a flat bed with a seat. These types of sofas are very durable, they can withstand high loads, so they are considered one of the most durable. But such models cannot be called compact.

Design features

It should be noted that the shape distinguishes island, straight and corner sofas. The latter are installed in the corners of the room. They are great for small rooms. This is one of the most modern and fashionable types of upholstered furniture. As soon as the sofa is in the room, it immediately becomes much more comfortable.

One of the advantages is the ability to vary the design and shape as desired. I must say that everyone, having considered the types of corner sofas, will be able to choose the one that suits him. The sides of such models can be the same or different in length.

Island sofas are most often sold in a rounded shape, and therefore, they cannot be placed in a corner and leaned against a wall. They should occupy a central place in spacious rooms.

Appointment of sofas

Such upholstered furniture for its intended purpose is conditionally classified into the following models:

At the same time, the mechanisms and types of models may differ, therefore, it is necessary to choose a specific thing that is directly suitable for your purposes. Often it is the types of sofa upholstery that determine their purpose. For example, models sheathed in leather are designed for kitchens or offices. For children's rooms, sofas are covered with bright and practical fabrics, from which it is easy to remove stains.

Types of sofas by size

All models are divided into compact and large designs. However, there is no single standard. One manufacturer makes a two-seat sofa 1.6 m long, and the other - 1.9 m.

It is necessary that the model that you like does not occupy all the free space in the room, does not block the balcony door. Before buying, measure the area of \u200b\u200byour room and compare it with the dimensions of the sofa.

We hope the tips in this article will help you make the right choice, and your sofa will serve you faithfully for many years. Good luck with your purchase!

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

Book ("click-clack")

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

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

Eurobook

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

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

Eurobook "Tick-Tock"

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

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

Accordion

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

Minimum assembled size.
Large bed size.
mechanism reliability.

Withdrawable

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

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

Cot

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

french look

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

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

American view ("sedaflex")

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

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

Dolphin

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

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

Conrad

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

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

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

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.

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

The mechanism of transformation of the sofa "Tango"

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

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

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

The 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.

Flaws: 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.
Flaws 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.

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

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

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

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

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

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

Advantages: in the assembled state it has small dimensions.

Flaws: 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.

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

The mechanism of transformation of the sofa "Italian folding bed

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

The principle of operation of the mechanism

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

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

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

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

Flaws lack of storage space for linen, high price

The mechanism of transformation of the sofa "Accordion"

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

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

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

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

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

Flaws: 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
Flaws: 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.
Flaws: 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.

Flaws: 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

Flaws: 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.

Flaws: 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, slats give a good orthopedic effect, adjustable armrests, you can create a sofa for yourself.

Flaws: 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.

Flaws: 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.
