Choosing a sofa layout mechanism

Sedaflex ("sedaflex")

The second name of this folding mechanism is “ Belgian cot". It is both easy to use and reliable, which makes Sedaflex ideal option transformations for permanent use.

The Sedaflex bed turns out to be perfectly flat, without bends and creases, and the folding mechanism itself is made of high-quality metal and therefore lasts a long time, it is produced by the Franco-Belgian company SEDAC-MERAL (which invented it).

"Sedaflex" is a two-fold transformation mechanism. Accordingly, first you pull one section out of the sofa, holding on to special loops, and then “unfold” it until the folding metal legs are on the floor. Load up to 200 kg.

Furniture with such a mechanism has a thicker mattress (usually a spring orthopedic mattress up to 18 cm thick is used), so the sleeping space is smooth and elastic. For more comfortable rest, the Sedaflex mechanism is equipped with an adjustable headrest.

"Millennium"

The millennium mechanism has a very nice feature: sofa cushions no need to remove and fold in the corner of the room - when unfolding the sofa, they are below, under the bed. To expand this mechanism, you need to pull the back of the sofa towards you and lower it. Very easy to fold into full bed!

- the most reliable and rather expensive transformation mechanism, while it is extremely convenient when laying out and provides a comfortable sleep.

This mechanism is designed for daily use. Design features mechanism is that at the bend points, not rivets are used, but unreliable bolted connections, based on metal grid and a rigid frame made of metal pipes.

The mechanism is very easy to unfold and fold thanks to powerful springs - all this ensures trouble-free operation of the mechanism in conditions of daily intensive use. The mattress is used up to 150 mm high, which is based on an orthopedic spring block "bonnel".

Meralat

The mechanism "meralat" is not intended for daily use - it is a "guest option". It is usually completed with a polyurethane foam mattress.

To start laying out the sofa, you first need to remove the seat cushion, and then unfold one and the second sections in sequence.

Upholstered furniture with such a mechanism of transformation, as a rule, is used as a very convenient and practical "guest option".

"Dolphin"

The dolphin transformation mechanism is mainly used in corner sofas, which are very popular today.

In operation, the “dolphin” mechanism is extremely simple and does not require special physical effort; even a child can easily decompose it.

For the transformation, it is necessary to pull the hidden strap with a characteristic upward movement and towards yourself, thus, the hidden part bed rises, is established and fixed in one plane with the main sitting, forming the equal and spacious place for rest and a dream.

The undoubted advantages of sofas with the "dolphin" system include its following remarkable qualities:

• Suitable for everyday use.
• Flat, spacious bed, which is high enough from the floor.
• Ease of transformation.
• Reliability and long service life. Retractable mechanism has always been considered more reliable than folding. Load up to 200 kg.
• Low cost.

"Eurobook"

In fact, the Eurobook transformation mechanism does not have a mechanism as such, from which the most important plus follows - there is nothing to break!

This is the most reliable and simple transformation mechanism.

For the layout, you need to push the seat forward, then lower the back of the sofa.

Designed for daily use.

From the advantages:

• a huge niche for linen;
• the ability to place close to the wall;
• wide range of sizes, both in length and width.

"Eurobook step by step" or "tic-tac"

The main difference is that the seat does not roll forward, but moves along a semicircle path. At the same time, in the process of unfolding, no wheels go on the floor. This ensures the safety of floor coverings.

"Book" or "click-clack"

The principle of unfolding is as simple as possible: raise the seat until it clicks, lower it and the sofa is laid out.

AT modern models an improved analogue of the "book" mechanism is often used.

However, the click-clack design provides for an additional intermediate position of the “relax” backrest (or even two of its variants).
Thanks to this improvement, a person can be in a half-sitting and reclining position.

In short, Sedaflex is a mechanism in a sofa for transforming it into a sleeping place and vice versa. Among others, it is considered one of the most popular because of its compactness, versatility and low cost. Plus it is suitable for small spaces.

The principle of operation of the mechanism

The sofa unfolds and folds easily. It is enough to pull in the direction - up / towards you. The sleeping place is established on metal legs. If necessary, hide the mattress headrest under the sofa cushions. It develops according to the same principle, only in reverse order.

Mechanism Sedaflex

pros

the compactness of the mechanism.

It is easy to unfold, does not require much physical effort - even a child can handle it. A sofa with such a mechanism can be put in the nursery.

having a flat bed. It will be comfortable to rest and sleep.

durable and reliable. Can support the weight of two adults.

minimal damage to the floor covering. Due to the fact that the mechanism does not “wiggle” on the floor, it practically does not leave scratches or scuffs on the floor covering.

Minuses

the main disadvantage is strength. Everything that was described in the paragraph above is an option when you buy a sofa from a trusted manufacturer whose product quality you are sure of. Another thing is when the manufacturer saves on materials.

the absence of a linen box in straight sofas with such a mechanism. The exception is the corner option.

Review 01.12.2013

Sedaflex (otherwise "Belgian sleeping bed") is a very easy-to-use bed transformation mechanism. Sedaflex has rightly been a success in different countries and recognized as the best of its kind. This is largely due to the material from which Sedaflex is made - this is a heavy-duty pipe, and Sedaflex, at the request of the customer, can be supplemented with an orthopedic spring block or foam mattress. Separately, it should be noted the versatility of Sedaflex - you can use it both daily and as a guest bed. No special skills are required when handling Sedaflex, even a beginner can handle it, as Sedaflex is very easy to use and, regardless of external conditions, is always happy to offer you or your guests a spacious, comfortable and exceptional flat surface for sleep.

Sedaflex is presented in several widths of the bed - these are 150, 140, 120, 100, 80 cm, each option is complemented by an adjustable headrest. Another advantage of Sedaflex beds is that they are almost completely silent during operation, you will not hear any squeaks and other extraneous noises that can disturb your sleep. The Sedaflex mechanism has an exceptional quality, which is reflected in all its elements, whether metal structure, armor or belts. Among the undoubted advantages of Sedaflex can also be attributed to the fact that this mechanism during operation is practically harmless to all floor coverings.

The activities of our company are entirely aimed at satisfying even the most fastidious customer, so our catalog reflects the range of materials required for the manufacture of upholstered furniture that meets modern standards. Not the last place in this glorious list is occupied by the Sedaflex mechanism, made in Russia together with the Belgian company Sedac-Mecobel. The Sedak Instroy Assemblies LLC association was established in 1998 with the aim of introducing Russian market furniture transformation mechanisms. We can be proud to be largest manufacturer such an important element in this area of ​​​​the market (various mechanisms are presented, including the fashionable and convenient Sedaflex) and are even able to withstand fierce price competition in this area.

In the 21st century, sofas with a transformation mechanism are very popular. Convenient and practical to use, they come in three types: with a roll-out mechanism, unfolding and unfolding.

One of the types of unfolding models is the Sedaflex or American clamshell transformation mechanism. The main criterion by which buyers evaluate it is ease and ease of use.

Mechanism Sedaflex

Actively used in structures upholstered furniture this mechanism began in the early 90s. The developers are Sedac. Representatives of the company took as a basis the "French clamshell", which consists of three parts, and improved it. "Sedaflex", unlike the "French", consists of two parts, has a mattress with spring blocks, has the largest dimensions, and also has built-in, rather than removable, pillows in the layout mechanism, which serve as additional support.

REFERENCE Furniture with a transformation mechanism appeared for the first time in the 17th century in France.

Sedaflex sofas are very compact in appearance. When folded, it does not take up much space, but when unfolded, it forms a full-fledged sleeping place. Harmoniously fit into any interior of the room. durable and reliable mechanism allows you to effortlessly transform it into a double bed every day.

Suitable for living rooms and offices. Often found in apartments with small living spaces. When choosing, you should pay attention to the following characteristics that affect the quality and service life:

Dimensions

Before buying, measure the distance from the sofa to the extreme point of the transforming part, in order to leave room for movement around the bed.

Sleeping characteristics

When purchasing a sofa bed, make sure that the bed will be comfortable while you sleep. Optimal Thickness the mattress should be about 15 cm, have a spring block and a soft filler. Not all models can fully replace an orthopedic bed.

Price and quality

High price is not a guarantee of quality. average cost sofa with the Sedaflex transformation mechanism from 10,000 to 40,000 rubles. The price depends on the materials from which the product is made: wood, steel, sofa upholstery, mattress filler. It is worth noting that furniture with removable elements is always lower in price than with built-in parts in the main structure.

IMPORTANT When buying expensive furniture, you must ask for a quality certificate from the manufacturer. it important point when issuing a product warranty.

The Sedaflex mechanism is a structure, the base of which is made of metal pipe. AT horizontal position held by strong legs that do not spoil or scratch flooring. The mattress is one-piece, fastened with elastic straps. The entire transforming structure folds in half and retracts into a niche in the sofa.

Step by step instructions on how to turn a sofa into a bed

Even a teenager can turn a Sedaflex sofa into a full-fledged bed. Three steps, effortless transformation is the main reason for choosing this model.

1. Remove all soft, removable elements, if any.
2. Pull up and, at the same time, pull the retractable structure towards you.
3. Lay out, folded in half, a bed, setting it on legs.

The procedure takes 2-3 minutes. The bed can also be folded back in three steps, only in reverse order.

Advantages of the Sedaflex mechanism

The main advantages of the "American clamshell" mechanism are:

• Simplicity and noiselessness during transformation.
• The mattress has orthopedic properties, without seams in the joints between its parts, which allows for a more comfortable sleeping place.
• The load on the structure is up to 300 kg.

The cons that buyers indicate in their reviews relate more to the sofa than to the Sedaflex transformation mechanism. For example, the use of thin steel for the manufacture of metal tubes makes the structure frame unreliable; thin mattress, as a result of the lack of comfortable sleep; the box for linen is present only in corner models.

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 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 event of complex mechanical devices the most preferable option would be the choice of transformation mechanisms made from reliable brands become.

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 starting position, you need to do the same operations in the 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 for expanding the sofa, which, in terms of smoothness of movement, really resembles steps 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 lodge is frame structure, the middle part is a platform completely standing on the floor and serving as assembled seat, the head is in the back.

When laying out such a sofa, you do not need to clean soft pillows, they will not interfere with moving 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 guides made of hard rock tree and a well-oiled mechanism allow such a transformation to be carried out without special efforts. 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 rotary mechanism transformation, which is also called "scissors". Usually these are large corner sofas with an ottoman. Outwardly, they are not very different from corner sofas other designs, however, 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 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 is made up of steel tubes different thickness(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 of bent plywood) and equipped with a mattress made of polyurethane foam, 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 respects, the duration of the service life of this model depends on the quality of the steel fittings located at its base, the reliability of the slats 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 everything inner place in the sofa is 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 pushed in lower part sofa. 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. Doesn't exist for them standard sizes. 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 may have various 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.

Before buying, it is advisable to visit furniture showrooms to see live 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 wood, for example, kiln-dried oak, ash or beech, will make the sofa durable and keep its beautiful appearance.

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 folding sofa, undoubtedly, is the presence in the apartment of space 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 which the buyer must consider.
