Apply a variety of layout mechanisms for sofas. There are no universal options. Depending on the method of operation, the size of the room and some other conditions, one or another mechanism for transforming the sofa is selected. In order not to make a mistake, you need to listen to the advice of experts. They will help you understand what factors you need to pay attention to in the first place.

When studying which sofa transformation mechanism is better, a number of recommendations should be taken into account. There is a generally accepted rule. All sofas are conditionally divided into guest types and designed for daily sleep. If the mechanism is chosen correctly, the furniture will last a long time and its operation will be comfortable.

If the sofa will be laid out often (sleeping variety), you should not purchase products with a complex layout procedure. In this case, the simpler the better. Guest sofas, on the contrary, are not designed for the daily movements of the system, so their mechanism will not be as strong as that of sleeping varieties.

Attention should also be paid to such criteria as the maximum load of the bed, the orthopedic qualities of the model, its appearance, the layout procedure, the comfort of the bed, and also the convenience in the sitting position. Therefore, the sofa transformation mechanism is an important factor influencing the choice.

Guest models

Sofas with "Clamshell" mechanism

The folding bed sofa transformation mechanism has several popular design options. The principle of transformation here is simple: the bed is located directly under the seat. For the front panel, which is located below, the seat moves forward. There is a French and American cot, their principle is very similar.

The French one is pulled out in the form of a scroll, which unfolds in 3 stages. This mechanism is compact in size, so it is built into even very sophisticated sofas. However, this model is not used on a daily basis.

The American clamshell is designed for heavy loads. This sofa is practical and durable. However, this feature significantly raises the price of this furniture. To transform the sofa, you need to lift it a little, and then pull it towards you. This type of mechanism does not harm the flooring, but it needs to be lubricated periodically to avoid squeaks.

Withdrawable mechanism

One of the best options for sleeping is a roll-out sofa. The transformation mechanism here is very simple. The berth is obtained by rolling out additional sections from under the base. Due to its simplicity, the presented mechanism is called one of the most reliable.

Another advantage of such products is the absence of requirements for the size of the room. It is installed even in small rooms. Moreover, in the unfolded state, the place to sleep will be long and even. The disadvantage of such mechanisms is the exactingness of the type of flooring. It should be strong, not sag under the weight of the sofa. In the process of transformation, the base slides on the floor. Nothing should interfere with this movement. It is better if the selected model of the presented type has rubber wheels.

Sofas with accordion mechanism

The mechanisms for transforming accordion sofas are gaining more and more popularity. It is very easy to apply in everyday life. The principle of the design device is to push the accordion. To do this, the seat is slightly raised. Next comes the click. The back of the two parts (in the normal state, it is folded with a house) is stretched. It resembles the movement of an accordion.

With the help of such a transformation, a flat surface is formed. When unfolded, the sofa looks like a regular bed. Usually "accordion" has removable covers for all soft elements. This makes the cleaning process easy. In the kit, almost all models have a linen box. In some cases, other decorative elements may be present. It is better if the basis of such furniture is a metal frame, steel frames. The mattress can be chosen orthopedic. For a small room, this option is acceptable, but you need to consider how much space the sofa will take up when disassembled. On the way of its layout there should be no extraneous things. There should be at least 0.5 m of space left to the opposite wall when the "accordion" is disassembled.

Sofas with the Dolphin mechanism

Check out the Monza sofa with the Dolphin mechanism!

The dolphin sofa transformation mechanism can also be called a kangaroo. It is most often found in sofas in the form of an angle. The front part slides out. An additional pillow is taken out of it with the help of a loop. She forms a bed. These sofas are quite large. The storage box is hidden in the corner module. The advantage of this model is a reliable and simple mechanism. This is an option for daily sleep. It is able to withstand heavy loads (about 200 kg). When laid out, an additional part of the structure takes up a minimum of space in the room. It should also be noted that the bed is spacious and has a fairly high rise above the floor level. The cost of the presented furniture is relatively low. This makes the "dolphin" very popular.

Swivel mechanism

One of the most modern is considered a corner sofa with a swivel transformation mechanism. It works very simply. One half of the furniture is rolled to the side 90º, and then it must be rolled to the other part of the sofa. It does not require the use of significant physical force. All movements are smooth. After the transformation is completed, the turning part is fixed. This creates a comfortable and spacious bed. The simplicity of the design makes the mechanism durable. It is possible to use orthopedic sofas for sleeping. It comes with a spacious bottom drawer for storage. On sale, such varieties of sofas are still quite rare. Their prices are above average. Therefore, if you want to purchase an easy-to-use, reliable and modern sofa, which is the corner swivel mechanism, you will have to spend some time looking for a responsible, trusted supplier.

The sofa is an integral element of the interior of any apartment. At first glance, they are all the same. However, the mechanisms for folding sofas are fundamentally different from each other. This question can play a decisive role in choosing one particular model. Therefore, it is important to understand this topic in advance, and only then go shopping.

There are three main layout options. All of them are popular and are regularly found in the furniture market. There are the following ways of folding and unfolding:

• Withdrawable;
• deployable;
• Folding.

Each of them has its own characteristics. Moreover, all of them are divided into many types, differing both in folding itself and in ease of use. All these varieties you need to know in order to choose the most suitable sofa for yourself.

Withdrawable

This type is very easy to use. All you need to do is pull the loop on the front of the sofa, after which it will roll forward. The roll-out mechanism requires accuracy, but with proper operation it can last for many years. A simple classic sofa of this kind will give the owner comfort during sleep and coziness in the house, achieved due to its compactness.

Eurobook

The Eurobook type is very convenient to use. Unfolding is very easy: the front extends and the rear manually lowers.

Advantages:

• Life time;
• Convenient folding process;
• Smooth surface;
• Inner storage box.

The disadvantages include large dimensions, due to which some people may feel discomfort when sitting. In most cases, "Eurosophy" becomes a good choice.

Pantograph

"Pantograph", which is also called "Tik Tak", is still the same "Eurobook", but has some improvements. When pulled out, the front side of the sofa does not roll on the floor, but is pulled out in the form of a small semicircle.

This type of layout avoids the risk of scratching the flooring. A separate advantage is considered a flat surface for sleeping.

The third name for this unfolding is “butterfly”.

Telescope

Such a mechanism unfolds very quickly: it is enough to pull the edge of the sofa, after which all its components will alternately stretch out in the same way as a telescope.

The telescopic sofa has its advantages:

• Sleeping height;
• Linen compartment;
• Compactness.

The disadvantages include a very large weight.

Conrad

The "konrad" mechanism is identical to the telescopic one. However, it is characterized by a higher bed height and increased convenience. When extending the elements, damage to the floor is excluded.

This is the most reliable mechanism, but its cost is completely unattractive.

Dolphin

In recent years, the "dolphin" has become popular. In the process of unfolding, the movements of the elements resemble a dolphin's dive. Often this type is used in corner sofas. You can also unfold it by pulling on the loop.

• Suitable for daily use;
• Sleeping area;
• Ease of operation.

There are no significant downsides to this design.

Kangaroo

This transformation mechanism is almost identical to the previous one. The only difference is the increased height of the supports. Sofas with such unfolding allow you to get the most comfort from sleep.

The pros and cons come down to the increased height of the supports, which gives more convenience, but reduces the level of reliability.

Ankara

Ankar operates on the same principle as the previous two. You need to pull the seat towards you and pull out the block by pulling it up. It is distinguished by increased reliability and spaciousness of the bed.

puma

The design of the puma pull-out sofa is very simple. You just need to pull up the seat, after which the base will stretch behind it. "Puma" has a high demand in the market, thanks to the safety of the floor and convenience.

Advantages:

• Silent folding / unfolding process;
• Ease of use.

Corner models are supplied with a special box for things, which is located on the back.

Sedalift

Sedalift is easy to use. It is ideal for sleeping, but many models suffer from low durability. The instruction manual calls for the lower part to be rolled out, the folded fabric section to be laid out over the extended base.

• Large bed;
• Ease of unfolding.

Of the minuses: the risk of scratching the floor, as well as low suitability for regular sleep.

deployable

All types of unfolding are comfortable, but this one causes a special feeling for many. The reason is the elegant appearance of the furniture when folded. This type is perfectly characterized by the word "clamshell". It is also often used in Russian names of subspecies.

In the unfolded state, the sofas resemble a folding bed familiar to many. The berth rests on supports and consists of a rather thin material. It is made up of three elements. It is only necessary to pull the edge of the seat so that the transformer sofa takes on a different look, and its two additional parts stand on supports.

What are the mechanisms of sofas - video:

This fastening does not allow you to use the sofa daily. It has reduced strength, and is also not very comfortable when lying for a long time. As a rule, they are used only in assembled form, and rarely laid out.

french book

This is the main representative of such a mechanism. The French book is unfolded by stretching the main part, which leads to the displacement of the other two on the supports.

• Express unfolding.

• unreliability;
• Irregularities on the surface.

It is worth acquiring it only if you have to lie on it extremely rarely. In other cases, it is better to prefer a forward-folding mechanism.

Spartacus

This subspecies was developed by the joint efforts of designers from Russia and Italy. This is the best unfolding sleep mechanism. It is a more durable French clamshell, reinforced with a metal grill.

• Strength;
• Comfort and suitability for daily sleep.

Of the minuses, only that the lifting mechanism requires you to remove the pillows before unfolding.

Rich

This mechanism, also called "American book", is similar to the French version. You just need to pull the seat towards you, after which everything will decompose. It differs in that it consists of two blocks, not three. It also has a thicker surface.

• High strength;
• Compactness.

It has another name - "sedaflex". Of the minuses, only the absence of a linen box.

As the previous version, the sofa of such a plan consists of two parts. The difference is that the transformation requires not raising the seat, but moving the backrest forward, turning the structure over so that the sofa rests on the legs.

• High reliability;
• The presence of springs.

• High price.

The spring mechanism allows you to extract maximum comfort from the furniture.

Accordion

Another popular option resembles, in its principle of action, the musical instrument of the same name. The design stretches in the same way as accordion bellows. Gradually, the sleeping place is pulled out, leaning on the legs. It is similar in size to a large double bed.

• Compactness;
• Ease of lifting;
• Reliability;
• Department for things.

• Risk of floor damage.

"Accordion" is very convenient to use and has an acceptable cost.

Caravan

The mechanism is based on a metal frame. Unfolds by pulling the seat up. At the same time, two platforms are pulled out under the base. After unfolding, it is comparable in size to a large bed. You can assemble a folding sofa very quickly.

Pluses in durability and simplicity. The only downside is the lack of a linen box.

Ribalto

The popular ribalto folding option is distinguished by a well-thought-out design. It attracts attention with its simplicity and convenience. The process of folding such a sofa is simple: you need to lower the back to the seat, then turn them over, laying them on the floor. This is how the bed is formed. There are models with automatic folding.

• Quick and easy folding;
• Space.

There are no significant disadvantages of the mechanism. Also called "slider" in the angular version.

Folding sofas

Modern folding mechanisms include a third type - folding. It is familiar to anyone who has had an ordinary inexpensive sofa. The main plus is the presence of a large size linen box.

Tango

Such a sofa is very functional, because when unfolded it is able to take several positions. It looks like a book. You need to pull the lower part, after which the back will lower.

• Intermediate folding options;
• Flat sleeping surface.

Of the minuses, only the inability to put the sofa close to the wall. There is also a recliner option with a retractable footrest.

Butterfly

"Butterfly" combines retractable and folding mechanisms. Allows you to fold and assemble the sofa as quickly as possible. First, the lower part is pulled out, then the upper one leans back.

• The speed of the mechanism;
• Bed size.

The disadvantages of a sofa of this form include the risk of damaging the rollers used when rolling out. According to the method of unfolding, the mechanism is very similar to the Eurobook.

Book

The classic mechanism for most people is a book. It is very easy to unfold and fold the sofa book. You need to fold the back back, after which it will lower, increasing the area for sleeping. This sofa consists of a metal or wooden frame.

The parameters allow you to fit inside a section for a large linen box. Other advantages include strength, simplicity and low cost.

Dominoes

The mechanism called "domino" combines rolling out, eurobook and dolphin dive. The lower part is extended, the back is folded and in the form of diving it goes down, forming a place to sleep. The characteristic of the sofa does not allow to include a department for things in the design, which makes the mechanism less attractive.

The main advantage of this triple design is the height of the bed.

Mechanisms for transforming sofas - briefly about each

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

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

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

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

Sofas without transformation mechanisms

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

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

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

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

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

The mechanism of transformation of the sofa "Book"

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

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

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

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

Sofa "Book" often contains a section for bedding inside

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

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

The mechanism of transformation of the sofa "Tango"

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.

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

Advantages: ease of converting the sofa into a bed, the simplicity of the mechanism itself - read its high reliability, large and even place to sleep, large niches inside the sofa for storage and bed.
disadvantages because of the wide seats, it is not convenient to sit on the sofa leaning against its back, especially for people with short stature.

Sofa transformation mechanism "Pantograph" ("Tick-tock", "Puma", "Walking Eurobook")

With the "Pantograph" the same story as with the "Tango" sofas. Apparently, for the sake of a red word, sellers and manufacturers have come up with a number of bright names for essentially the same mechanism. So, what else did I manage to meet under the mask of "Pantograph" - "Tick-tock", "Puma" and even "Walking Eurobook". In order not to get confused, I will continue to call the mechanism "Pantograph" (sounds somehow solid and mysterious))) .

"Pantograph" originated as a variant of the "Eurobook" mechanism. The difference is that there are no roll-out rollers in the "pantograph". Otherwise, it has parameters similar to the "Eurobook". Equipped with internal storage niches, it has a large and even bed.

The principle of operation of the mechanism: For unfolding, it is enough to pull up the sofa seat by holding its edge in the middle. Often sofas are equipped with loops - handles for easy unfolding. By pulling up the seat of the sofa, you activate its mechanism, which pushes the seat up and forward and at the same time opens the legs of the support and stands on them. The pillow back is placed in the formed niche. The result is a flat, without visible joints, a place for two people to sleep.

Advantages: sofas with "Pantograph" have a comfortable place to sleep. The mechanism is easily laid out. Such a sofa will not spoil your flooring, because when unfolding, parts of the sofa do not ride on the floor.

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

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

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

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

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

When assembled, the "French folding bed" is small in size, but 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.

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 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.

disadvantages lack of storage space for linen, high price

The mechanism of transformation of the sofa "Accordion"

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

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

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

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

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

Disadvantages: the sofa, when brought into the sleeping position, rides on the floor, so it can damage the flooring.

The mechanism of transformation of the sofa "Spartacus"

The principle of the mechanism: Triple folding mechanism. It is necessary to pull the seat of the sofa and it will decompose in three steps while standing on extended legs.

The design of the mechanism was developed by Italian engineers. This mechanism belongs to the metal-frame mechanism. The frame is made of shaped pipes on which a dense mesh made of metal rods 4 mm thick is mounted. The frame consists of three sections. The mesh creates a good orthopedic effect. On top of the mesh is a polyurethane foam mattress. It is comfortable to sleep on such sofas. The design of the mechanism provides a large bed in length, which is especially important for tall people. The mechanism is very reliable because it does not contain wooden and plastic parts.

Advantages: reliability and durability, easy to unfold, can be used daily, flat and large bed
Disadvantages: there is no place to store bedding, since the mechanism occupies the entire interior space of the sofa when assembled, you need to remove the sofa cushions before unfolding.

Sofa with unfolding on the floor

The principle of operation of the mechanism The sleeping place consists of two sections. When folded, the sections are hidden inside the sofa body. To unfold the sofa, you need to pull up on the inner edge of the sofa seat. Then, pull the sections forward towards you. The berth has no supports and unfolds directly on the floor.

It cannot be said that the sofa is comfortable for sleeping, since the joints of the sections are noticeable and the bed itself is located very low. Therefore, such models can be used for occasional use as a bedroom. But for sitting it is quite an acceptable option.

Advantages: compact dimensions in the assembled state, the cheapest type of folding sofas.
disadvantages: not comfortable to sleep, no storage space for bedding

The principle of the mechanism: The sleeping place consists of two segments. In the assembled state, the segments are in the sofa body. To unfold the sofa, you need to pull the bottom of the front. After that, it will roll forward into the working position. All that remains is to fold the pillow into the vacant seat. As a result of the transformation, a comfortable place to sleep is formed.

Roll-out sofas are durable and reliable models. Well suited for frequent use. Contain internal space for storage of bed linen.

Advantages: the most reliable, have a comfortable place to sleep and compact dimensions when assembled.

disadvantages: roll-out sofa rollers can ruin the flooring when unfolding, the bed has a low height

The folding mechanism of the sofa "Konrad" ("Telescope")

The principle of operation of the mechanism: "Konrad" consists of three sections. To unfold the sofa, you need to pull the lower part of the sofa from the front. In this case, the sections roll out one after the other. Because of this feature, the mechanism was nicknamed the "Telescope". Sections roll out and stand on supports.

"Conrad" is a subspecies of a roll-out sofa. The main difference is the large height of the bed.

Advantages: reliable mechanism suitable for daily use, sofas have a compact volume, equipped with a box for linen, comfortable for sleeping

Disadvantages: mechanism and sofa are heavy

The mechanism of transformation of the sofa "Dolphin"

The principle of the mechanism: To unfold the sofa, pull the front of the sofa from below. As a result of this, a section hidden inside the sofa body will roll out onto you. Inside the roll-out section there is a pillow with a strap. You need to grab the strap to pull the pillow up. She will "emerge" and stand on the same level with the cushion-seat of the sofa. Voila, the sleeping place is ready.

The Dolphin mechanism is mainly used in the construction of corner sofas. Places for storing the bed are not located in the roll-out part of the corner sofa. The mechanism exerts a significant load on the body of the sofa, so when buying, pay attention to the material of the body. Knots are not allowed if wood is used.

Advantages: ease of unfolding, the optimal height of the bed.

disadvantages: not durable.

The mechanism of transformation of the sofa "Elf"

The principle of the mechanism: The mechanism unfolds easily. Armrests are bred on the sides and a berth is formed.

"Elf" refers to metal-frame mechanisms. The frame is made of metal profiled pipes. Wooden slats. Armrests are adjustable in height and have several positions. This feature allows you to create the most comfortable position of the armrests for the reclining position.

Advantages: compact model of sofas, a good flat bed, the lamellas give a good orthopedic effect, the armrests are adjustable, you can create a sofa for yourself.

Disadvantages: you can not put the sofa close to the wall, the bed is in the same place as the seat.

Sofa transformation mechanism "Recliner"

"Recliner" got its name from the English word recline - reclining or leaning back

The principle of the mechanism: The sofa transformation is controlled by complex mechanisms hidden in the sofa body. With their help, you can adjust the inclination of the back of the sofa and extend the footrest to a predetermined distance and at a certain angle.

Some models have vibration massagers built into the sofa cushions. Particularly advanced sofas have built-in electric motors that control the transformation of the sofa using a remote control.

There are models with "memory" that can adjust and remember the settings of the mechanism made directly for your body.

Advantages: very easy to manage, have fine settings - you can create a sofa for yourself.

Disadvantages: high price, used only as a place to relax, as there is no place to sleep

General conclusions

• Pay close attention to the mechanism when buying a sofa. The ease of use and life of the sofa will depend on choosing the right mechanism.
• Match your needs with its capabilities. How often will you lay out the sofa, what space do you have allocated for installing the sofa, especially when unfolded.
• Do not take a sofa with a obviously inappropriate mechanism just because the color is cool or because the neighbors have one. Choose individually for your needs.

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.

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 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.

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

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

Varieties

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

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

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

"Dolphin"

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

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

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

"Eurobook"

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

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

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

"Pantograph"

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

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

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

"Puma"

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

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

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

"Conrad"

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

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

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

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

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

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

Transformer

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

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

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

"Accordion"

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

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

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

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

"French" folding bed

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

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

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

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

"Sedaflex"

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

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

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

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

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

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

"Telescope"

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

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

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

How to choose?

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

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

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

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

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

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

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

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

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

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

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

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