Sofas with mechanism "Accordion"

Modern upholstered furniture is the basis of a cozy family nest. Among the huge range of models, the sofa with the mechanism “Accordion».

The main difference of such a sofa is its mechanism. It unfolds on the principle of an accordion and for its transformation needs a certain space. The mechanism of the model is quite simple: the sofa can be expanded in a maximum of half a minute, which is one of the advantages of such sofas.

Turning into bed means unfolding the components: one part moves forward, while the other two go down. When folded, this model does not take up much space, so it fits in almost any room.

This sofa is multifunctional: in the daytime it can be a compact sofa for receiving guests, watching your favorite TV shows, and at night it can easily turn into a bed,where you can accommodate the owners of the house or their guests.

A sofa with an accordion mechanism is of two types: straight and angular. Despite the different shape, each model has the same transformation mechanism, the design of which is characterized by reliability and durability.

Usually such a sofa is purchased for a long time and has a long service life. It is durable, so it is well suited for unfolding every day and takes one of the leading places in the line of folding sofas. In order to decompose it, you do not need to remove additional details: it does not have backrest cushions, but it differs by the same thickness of the backrest and the seat. More often vykatny models make with a linen box.

The advantages of the sofa with the mechanism "accordion" include:

• easy folding mechanism (which will cope with both an adult family member and a teenager);
• ease in operation;
• strengthdue to the presence of the frame;
• Availability different types of filler a sofa that allows you to choose the most convenient option for the specific requirements of the buyer;
• large selection of colors, thanks to which you can buy a model with regard to color preferences, as well as to the style of the interior;
• different size models;
• the model can be bought in a store or ordered according to individual parameters, supplemented with a linen box and pillows.

In addition, this model of the sofa performs not only the main load. In addition to determining the place for rest and sleep, a soft sofa gives the atmosphere of home comfort. He is able to complete the style of any room. And in some cases, this furniture delimits the area of ​​the room.

Dimensions of the sofa depend on several factors. They vary depending on the type of model (straight, angular). In addition, the sizes of a sofa of each trademark differ also. In general, all designs have a large sleeper, the average length of which is 198 cm, width - from 120 cm to 218 cm.

The usual depth of such models is 100-103 cm, and the height of the berth is about 40 cm with a sofa height of 85 - 90 cm.

Some models have a large sleeping place, the length and width of which is 210 cm.Such options are designed for spacious rooms, bedrooms or living rooms.

In the production of modern upholstered furniture with the mechanism of "accordion" companies use different materials. Each type differs in properties, durability and price. The most expensive material today is genuine leather.

Such a sofa always looks luxurious and expensive, it is easier to clean, since cleaning the surface from dirt, dust or moisture is not difficult. However, the leather sofa is much more expensive than its counterparts, so as a budget option, manufacturers produce models of eco-leather or leatherette.

The main line of models are sofas with textile upholstery. Furniture tapestry remains the most popular upholstery material. Such textiles are distinguished by bright colors, a variety of patterns and a relatively lower price. The advantage of this upholstery is breathability. Thanks to her, in the blocks of the sofa will not appear mold or fungus.

The disadvantages of upholstery material include less practicality.. If you don’t get capes for such a sofa, it will quickly become dirty, form scuffs, hooks, and may tear. In addition to basic materials, flocking is used for upholstery, as well as velor "chinchilla" (Korean-made fabric).

In addition to the upholstery, in the production of sofas with the mechanism "accordion" use a different block filler. It can be of two types: spring and springless. Simply put, the filler is a material that fills the mats of the seat, backrest and armrests. In addition, it is used in some designs that have, in addition to the backrest, additional pillows.

By origin, the filler can be natural or synthetic. The main varieties of sofa mattress filler are:

• standard polyurethane foam (T);
• integral PU HR (cast format);
• natural and synthetic latex;
• synthetic winterizer;

• synthetic down (sintepukh);
• holofiber;
• coir (coconut fiber);
• periotek (derivative of natural or artificial felt).

The filler makes the design softer. Some varieties are needed for an additional layer of the block, others are used only in the cushions of the backrest.

The frame of the sofa is its basis. It depends on the durability of the model. Today, manufacturers produce upholstered furniture from different materials. The most reliable version of the sofa with the “accordion” system remains the metal frame, as well as the combined type of construction, when wood is used in addition to steel. Such a frame is reliable, it significantly prolongs operation and, unlike a plywood case, with or without wood, will not creak.

Upholstered furniture with the mechanism of "accordion" is such at the expense of soft blocks. Their shape, thickness and size depend on the model, type of frame and base.

This design does not contain steel parts, so it will not break and will not creak over time. However, its quality will be different. Polyurethane foam of usual type represents foam rubber in sheets. To make a mat, take sheets of different density and connect, then trim the edges.This material is the most simple and budget.

Molded polyurethane foam has a more dense structure, so it does not rot, but only slightly sags during intensive operation, and in some cases can change the original color at the edges. However, it is considered the best option for the springless unit, therefore it is in great demand among buyers.

The spring block today is different from those varieties that were in Soviet times. It is of two types: dependent and independent. All types of block can be divided into three types: snake, bonnel and independent type. The difference between them lies in the fact that in the dependent type the steel elements are interconnected, therefore, under load, they function together.

A flat snake is essentially a similarity to the base of a horizontal type. It replaces the lattice base and is distinguished by elasticity. Each metal element is located at the same distance from each other, is attached to the frame and is interconnected in certain places,without disturbing the integrity of the mesh. This type needs a separate mat, in contrast to the blocks that are laid on the ground.

Bonnel is a vertical block construction in which the springs are more complete, have a twisted shape and are arranged vertically. They are attached to the top and bottom edges of the grid frame, and also connected to adjacent elements. Externally, the block looks like a metal skeleton mesh.

This unit is the most reliable and ensures the correct position during sleep or rest. The whole thing is in the design of the springs: each metal element of the twisted form is separated from the others, the springs do not connect with each other. They are packaged in individual cases of fabric, which are fixed among themselves.

The effect of such a mat is unique: under load, only the necessary springs are pressed, the rest remain in the initial position. Simply put, if two people sit side by side, neither of them will fall to the other, and everyone will have an equal position of the spine.

When choosing a sofa with an accordion mechanism, it is not enough to consider only the color of the upholstery, the size of the sofa and its design. Since such upholstered furniture is not bought for one year, you need to take into account a number of factors. It is important not just to fold and fold the sofa, appreciating the reliability of the design. If the purchase is carried out in the store, you need to carefully examine all the questions to which experts advise to pay attention:

• to assemble the sofa should be easy; during the inspection it is important to evaluate the transformation mechanism itself: if it sticks or seems loose, such a model is no good, it will quickly break down and will not last as long as we would like;
• robust construction made of steel and has a large diameter metal parts folding mechanism;
• when buying a model with wooden armrests it is necessary to give preference to the variant with rounded sidewall parts, this will save from accidental injury;

• if the sofa model is quite dimensional, it is better to buy a version with an orthopedic effect. This eliminates the effect of immersion and creates all the conditions for a fully comfortable rest or sleep;
• so as not to get confused with the type of hardness of mats for a sofa like "accordion", it is worth choosing between dense PU foam of class HR or an independent spring block. Both options are good, do not slip and provide less strain on the spine during sleep;
• Furniture with removable covers is considered to be the best sofa of the model with the “accordion” system. - they can be replaced, washed or cleaned, extending the life of the sofa;
• if the model is intended to replace the bed, the surface of the blocks should be flat, without relief and fittings. No stitches with additional filling, decorative buttons, otherwise it will be difficult to sleep on such a bed;
• the thickness of the seat and back blocks must be identicalIt is important that they are executed in the same way, otherwise the bed will not be even.

Choosing a sofa is a topic that needs to be approached thoroughly.Since the main task of upholstered furniture is the organization of rest and sleep, a sofa with a spring block and orthopedic effect will be an ideal choice. In the process of inspection, you need to check the transformation mechanism several times, because the sofa will constantly be assembled and laid out. You should not save on filler and frame, otherwise in a couple of years you will have to return to the topic of buying a sofa.
