folding

Folding models are quite convenient to use. To make a spacious bed out of a compact sofa, you will need to spend a few seconds of free time.

Folding sofas include:

Accordion

When folded, it occupies a minimum of free space, when unfolded, it provides a spacious sleeping place. As a rule, the bedding storage compartment is located in a niche under the sofa. Its advantages include: the durability of the folding mechanism, stability and reliability, ease of transformation. Cons: since with this method the sofa unfolds forward, then there should be enough space in front for its transformation.

Dolphin

The most popular corner sofa that unfolds by pulling the loop under the seat towards you. When unfolded, it pleases consumers with a spacious bed and an additional drawer for linen. Its advantages include: the presence of a comfortable and spacious bed, ease of unfolding, aesthetic appearance.

The Dolphin mechanism exerts a heavy load on the body of the product. Therefore, it is necessary to choose products from high-quality and durable materials.

Book

When unfolding a piece of furniture, its back leans back. To do this, you do not need to move the product away from the wall, as it is immediately installed with a small margin. Book models consist of a metal or wooden frame, spring blocks or any other filler. At the bottom, they are often equipped with linen drawers. Its advantages include: strength and reliability, wear resistance ease of use.

Eurobook

It belongs to the classic models, in which, when unfolding, the seat is pushed forward, and the back is lowered in its place. Its positive qualities include: ease of unfolding and folding, reliability of the mechanism, a large bed, the presence of a niche for storing things.

Click Clack (Tango)

Refers to an improved model of a sofa-book. The product got its name because of the sounds that are made when the mechanism is unfolded.

The model has three positions: lying, sitting and reclining (relaxation).

Some products are additionally equipped with side parts that transform into armrests and headrests. Even when unfolded, upholstered furniture occupies a minimum of free space and is perfectly placed in small apartments.

Tick-tock (pantograph)

Its transformation system resembles a eurobook, only there are no roll-out rollers. Inside there is a spacious box for bedding. To unfold the Pantograph, it is necessary to pull the seat up, grabbing it by the edge in the middle. The advantages include: ease of use, the presence of a spacious bed, the absence of rollers that spoil the floor covering.

French cot (aka Spartacus)

It consists of three sections, which are laid out by pulling the product over the edge of the seat. The French folding bed model is not intended for regular unfolding, as its mechanism wears out quickly. When assembled, the sofa takes up little space.

Sedaflex (American folding bed)

It unfolds like a French folding bed, but differs not in three, but only in two sections and a thicker mattress. Among the advantages it is worth noting: the strength of the transformation mechanism, compactness, the presence of a comfortable and high-quality mattress.

Italian cot

The advantages of the model include the fact that for its unfolding there is no need to first remove the pillows. This option is one of the most reliable and easy to use.

puma

It is worth adding to the advantages: compactness, ergonomics and original design.

Saber

Quite an easy-to-use type of construction that can be fully or partially unfolded. Features include the presence of a linen box and a high place to sleep. Depending on the chosen modification, the bed consists of two or three sections. To unfold the product, you need to roll out the seat, fold the backrest forward and lower the additional shelf.

With withdrawable mechanism

In roll-out models, one or two sections of the sofa are hidden in its body. To unfold the product, you need to pull the bottom part towards you.

Common models include:

• Venice. The principle of operation of this withdrawable mechanism (see photo above) resembles the Dolphin model. To prepare a sleeping place, it is necessary to push the section, which is located under the seat of the sofa, all the way towards you. After that, the pillow that hides inside will lean back into the vacant niche. The piece of furniture is quite simple and easy to use. Manufacturers offer straight or angular models that do not take up much free space;
• Telescope. To unfold it, you need to pull its lower part towards you. In this case, the sections will roll out one after another and stand on their legs. The advantages include: a sleeping height that is comfortable for sleeping, the reliability of the mechanism, the possibility of regular use, compact volumes, the presence of a box for linen. But keep in mind, due to the unique unfolding system, the product is quite heavy in weight.

with swivel mechanism

A feature of models with swivel mechanisms can be called the ease of unfolding - folding. In them, the entire load goes to the frame, they do not need to lift the blocks and roll out the sections to the stop. Depending on the chosen model, both one part of the sofa and each individual block can turn when unfolding.
A popular model of a sofa with a swivel mechanism is:

• Scissors. Its transformation mechanism is to rotate one section to another. At the same time, the blocks are securely fixed to each other with a metal fastener from below. When transforming sections, a bed with bedside tables is obtained.

Without folding mechanism

These pieces of furniture do not contain any transformation mechanisms. That is, they do not fold out and are intended only to create comfortable seats. Such options are a practical decoration of the living room, where guests will comfortably accommodate. Also, non-folding sofas are found in the interiors of hallways, kitchens and dining rooms. Their benefits include:

• lack of a transformation mechanism (hence, nothing can break in them);
• long service life;
• stylish and aesthetic appearance.

Some people use sofas without transformation mechanisms for sleeping. It will comfortably accommodate one average person.

Mechanisms for transforming corner sofas

Corner sofa models are considered practical, functional and roomy. They are a real find for small apartments. Since they are distinguished by a large number of seats and a spacious sleeping bed. They are installed in the corner of the room (left or right) and occupy a minimum of free space.

Almost all transformation mechanisms are suitable for daily use of corner models. The Dolphin is considered an ideal option, as well as the Scissors model, which unfolds in several movements, and even a child can cope with this matter.

Which sofa mechanism is better

Since all sofa transformation mechanisms differ significantly from each other, the question arises before consumers: which sofa mechanism is better. Here it is worth starting not only from personal wishes and financial possibilities, but also from the purpose of the piece of furniture.

For daily use

For daily sleep, it is better to choose the following types of folding sofa mechanisms: accordion, eurobook, tick-tock, puma, dolphin. An excellent solution for every day would be a rotary or withdrawable mechanism.

If the product is bought for the purpose of regular operation, first of all, attention is paid to its design and the quality of the frame, which will be subjected to maximum load.

When choosing a sofa, it is important to consider the type of its filler. He can be:

• spring. In such a product, twisted springs are located inside in a vertical position. They, in turn, are divided into dependent and independent. The second option is more reliable, since such a filler does not bend, and during rest the spine is maintained in the correct position;
• springless. Differs in orthopedic effect, safety and convenience in use. Such products guarantee a sound and healthy sleep.

When choosing a sofa for daily use, you should pay attention not only to its folding mechanism and how it works, but also to the degree of mattress rigidity, upholstery quality, and the ability to change covers.

As a guest option

Compact models are used as guest sofas, which are laid out from case to case. Quite often, they are equipped with not very strong unfolding mechanisms (for example, a French folding bed), and it is not always comfortable to sleep on them. In these products, the main emphasis is on the spaciousness and convenience of seats, and the function of the bed in them is secondary.

Which sofa mechanism is the most reliable

Most people say that the most convenient and reliable transformation systems are: roll-out, as well as straight and angular models that use such a type of layout as an accordion or a telescope.

When choosing a transformation mechanism, several factors should be considered:

• how much space does upholstered furniture take when folded and unfolded;
• purpose of furniture (for daily sleep or as a guest option);
• intensive load mode;
• ease of operation;
• frame quality.

A good product will:

• have an impeccable movement of the mechanism without any jamming when folding and unfolding;
• differ in high-quality assembly;
• lined with wear-resistant upholstery;
• resistant to high mechanical loads;
• differ in a strong and reliable frame.

In conclusion, it should be noted that the quality of the sofa transformation mechanism directly affects its durability, practicality and ease of use. It is better to give preference to proven and well-established manufacturers with an impeccable reputation. Then the newly acquired furniture will please you with high technical characteristics, aesthetics and functionality.

It is difficult to imagine an apartment, house or office without a sofa. You can not only sit on it, but also use it for relaxation, but whatever this product is, it brings coziness, comfort and warmth. Typically, types of sofas differ in design, type of upholstery and method of transformation.

Let's see clearly what sofas are. Furniture companies have developed various designs of this type of upholstered furniture. They are represented by corner, children's, leather and other models. It is important to know how products differ, what transformation mechanisms are, and which one is best to choose. You also need to know other features of upholstered furniture, which determines its price range.

Manufacturers present us with a huge selection of sofas for every taste.

Corner sofas will decorate any home

Consider, for example, corner sofas. This upholstered furniture has won its niche among the popularity of the population. Models can have different transformation mechanisms. So the corners are very convenient. Such pieces of furniture are both left-handed and right-handed. In this case, you need to imagine and plan where in the apartment your purchase will be placed. But some models are collapsible and they can be interchanged and assembled like a designer, these are the so-called modular sofas.

Among the modular ones, they are especially popular with the population. The principle of its operation is similar to the jump of a dolphin that emerges from the water. It should be noted that corner sofas with a dolphin mechanism are also easy to use, and their comfort, smoothness and is considered an advantage.

Eliteness is a property of leather sofas

Among the various types, leather ones occupy a special crown place. They are beautiful in any interior, provide a great opportunity to relax and unwind. Leather is quite an expensive material, and, nevertheless, such sofas are quite in demand. They indicate the secured financial position of the owner, his high status, solidity and success. Leather is a durable and practical material that, in the form of furniture upholstery, will last a long time. buy for the office, where they mainly decorate executive offices and meeting rooms. They make the most favorable impression on clients and business partners.

They differ in the number of seats. They are triple, double and corner. A good sofa is made from deciduous, coniferous - hardwood. Usually the raw material is beech, birch, alder wood. Sofas differ in various models, colors and style solutions.

Leather is and will be an expensive, solid upholstery material.

Simple and easy to unfold the sofa

If we consider the mechanisms of transformation, then one of the most convenient is the "Eurobook". It is durable and has a long service life. The principle of operation of such a product is simple, just roll the seat of the sofa forward, then move the back to a horizontal position from a vertical one, and your sofa is laid out.

It should be noted the obvious advantages of these types of sofas: ease of transformation, size and comfort of the bed, reliability, the presence of drawers for linen. It is also important that the sofa can be installed close to the wall. When purchasing a sofa, it is important to pay attention to the presence of a spring block, orthopedic armor, as well as molded elastic polyurethane foam, which should be in the soft elements of the back and seats.

When studying the market, take a closer look at. It has a special folding mechanism that unfolds like an accordion and stretches out. Accordion sofas are ideal for those who do not want to spend a lot of time and effort preparing a bed in the evening and cleaning it in the morning.

An easy-to-use transformation mechanism allows you to make a luxurious bed out of one movement, and it is just as easy to return a piece of furniture to its original state. This factor has become an advantage of upholstered furniture, earning popularity among consumers. In fact, "Accordion" is a sleeping place, which consists of three parts. One of them is before transformation - a seat, the other two fold, forming a back. These sofas are of two types:

• sleeping place - latoflex, metal frame with mechanism, removable cover, mattress;
• filler and drapery - a single non-disassembled module, classic: frame.

Sofa "Eurobook" is simple and very convenient to use

Accordion sofas are durable, thanks to the design a sufficiently large sleeping place up to 180 cm is created. Accordion sofas, which have a metal frame in their design, are easy to care for, since removable covers can be washed. Such a transformation mechanism allows you to create seamless sleeping places, but the main thing is that the orthopedic system based on latoflex provides a comfortable and healthy sleep.

Consumers appreciate the durability of upholstered furniture

On the furniture market, domestic and foreign manufacturers of furniture products present sofas with a roll-out transformation mechanism. Such models have gained popularity among the population, thanks to the technical and consumer characteristics of sofas. Upholstered furniture of these types is particularly durable, designed for daily unfolding and heavy loads. When assembled, a sofa with a roll-out mechanism takes up little space, and when unfolded, the area of ​​\u200b\u200bthe bed increases by 3 times compared to its original position.

The sofa-book got its name from the similarity of the principle of operation with the opened book and appearance. This piece of upholstered furniture has been at the peak of popularity for a long time, thanks to its excellent consumer properties, such as versatility and convenience.

If the sofa book is folded, it looks compact. When folded, the backrest and seat are the same size. The design provides for a large and roomy drawer for various things, but to a greater extent. The box is located under the bottom. More advanced models of upholstered furniture are equipped with mechanisms that adjust the tilt level of the headboard when folded. However, at the same time, this type of sofa with a spring block has a drawback - wear and tear, that is, performance is worse than in other types of upholstered furniture designs. Therefore, book sofas can be bought relatively inexpensively, and their low price is always an order of magnitude lower than the cost of other representatives of this type of furniture. Furniture companies produce various modifications of "books", which come with and without armrests. Some models have different designs, for example, embossed backs are available,

The sofa-book will save your space during the day, and at night it will be a full-fledged bed

A variety of transformation mechanisms is the key to the consumer's heart

They deservedly took their place in the family of upholstered furniture. These models allow you to fix the back in various positions, including for resting at night. This feature has become fundamental when choosing upholstered furniture by the population and their preferences.

Another representative of upholstered furniture is a sofa with a pantograph mechanism, which has a fairly simple unfolding system. To increase the sleeping place, it is necessary to slightly pull the seat up and towards you, and then the design will automatically continue the initiated action, that is, the seat will rise slightly above the floor, and then lower. Further, according to the principle of unfolding, as in, the second block is unfolded into a horizontally-console position. The advantage of the pantograph mechanism is that it does not touch the floor during the transformation.

The pantograph makes a certain part of the sofa seem to rise up. Therefore, it is also called a "walking" piece of furniture. It turns out that even a child can decompose such a sofa. This transformation mechanism is widely used in both straight and corner sofas. A box for bed linen and other textiles and things is located under the seat.

Among upholstered furniture, sofas with a puma mechanism are easily and smoothly disassembled. This principle of transformation resembles the movement of a cat's paw, which is why the mechanism was given this name. Its advantage is easy unfolding, that is, in order to prepare a bed, you need to make a minimum of effort. It is important that during the transformation the sofa does not touch the floor. Therefore, even the most delicate flooring will not be damaged by frequent transformations.

Even a child can handle the sofa transformation mechanism

To unfold the seat, pull the seat up and towards you a little, and then the mechanism will do all the work. The seat "jumps" forward, and the second block, which is located under the seat, rises up. Thus, a wide and even bed is formed. Upholstered furniture in the form of puma sofas can be made using various fillers: from a block of independent springs to polyurethane foam.

The best upholstered furniture for children

Upholstered furniture, be it sofas with a sedaflex mechanism, or very comfortable and comfortable sofas with an American folding mechanism, create a cozy and comfortable atmosphere in any room or room, complement the interior, bringing elegance and sophistication to it. These statements fully apply to children's sofas. This piece of furniture is often bought instead of a children's bed, this is especially justified when the children's room is small.

When purchasing such a sofa, you should take care of the health of the child. Therefore, preference should be given to items that are made from environmentally friendly materials. The frame of the sofas is made of wood, most often pine, which is easy to process, and at the same time it is inexpensive. Sheep wool, straw, horsehair, swan's down, etc. are used as a filler. In the event that the child suffers from allergies, then you can choose a sofa filled with artificial materials.

Upholstered furniture is now produced universal, so it is suitable for both a teenager and an adult. Sofas are available in various designs, but recently it has become a fashion favorite. It can be used at night as a bed, and during the day it turns into a compact sofa, thereby freeing up space for playing, playing sports. For children and teenagers, manufacturers have provided sofas with a transformation mechanism (a book and a folding mechanism). As a rule, all pieces of furniture have a special box or space inside the structure where a child can put things. This advantage allows the room to refuse to purchase additional pieces of furniture, such as or a cabinet. Thus, the free area of ​​\u200b\u200bthe premises is significantly expanded, and the family budget is saved.

When buying a children's sofa, remember, you should not save on a child.

When choosing sofas for children, experts recommend paying attention not only to the design, colors, but also to the safety of the product. Upholstered furniture should not have sharp corners, open metal parts. It is these elements that can become an obstacle, hitting which a child can get hurt.

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 a comfortable sleep and limits the 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 as far as it will go, and lower the back back into 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.

The sofa has become an integral and absolutely necessary part of our home life. But, if it will be used as a sleeping place, its choice becomes an even more serious task. Choosing the right sofa bed for any of the rooms of an apartment or house is very important. After all, you have to deal with him every evening and morning.

In this article we will talk about choosing a sofa folding mechanism and which layout mechanism to prefer. We will tell and show how sofas are laid out.

How to evaluate the mechanism for turning a sofa into a bed

There are four criteria for this:

1. how the bed is located relative to the back - perpendicular or parallel;
2. whether the mechanism is so reliable that it can withstand daily use, or is it only suitable as a guest sofa;
3. how convenient is it to lay out the sofa;
4. is it possible to quickly fix the mechanism if it breaks.

It should be noted that with the location of the bed parallel to the backrest, it will always be narrower than that of a sofa that unfolds forward (perpendicularly). Indeed, with an increase in the width of his bed, the depth of the seat and the height of the back of the sofa increase accordingly, and it becomes uncomfortable to sit on a folded sofa. While the width of the perpendicular berth is equal to the width of the sofa.
