Sofa with spring block

In the rhythm of modern life we ​​must not forget about the most comfortable rest. The furniture should be not only beautiful, but also comfortable. When creating upholstered furniture, modern manufacturers began to use polyurethane foam more often, therefore the sofa with a spring block is a controversial topic today. This is not a classic, as it may seem at first glance. Today, the spring unit is different from the earlier analogues, and therefore in great demand.

The spring unit has significant differences from other sofa fillers. It is based on a steel structure made of different types of springs. Such material differs from foamy foam, which is an innovation, can be quite dense, but it bends faster and sometimes forms dust on the edges. The spring block is more practical, it can withstand a large weight load, and with a certain structure of the mat it can have an orthopedic effect.

This sofa is a good alternative to the bed, as in the unfolded state, it can replace it. In this case, the surface of the sleeping bed is almost always flat and elastic.

Such furniture is different cost and is selected in accordance with the planned budget. Sofas with a spring unit can be classic or provide an orthopedic effect - depending on the destination. The spring block may have additional padding layers. This enhances the elasticity, rigidity of the structure and contributes to the correct position of the body during sleep. Such sofas are considered especially reliable, they are purchased for those who need to prevent spinal diseases (or for those whose work is associated with serious physical exertion).

There are three types of springs for a sofa:

• Classic type. A design with a vertical arrangement of springs, where the elements are fastened between themselves and the frame at the top and bottom. This elastic system has a drawback: if you sit, being located outside the center of the mat, the spine is bent.
• "Snake". The block is a frame made of steel with springs in the form of snakes attached to the frame and interconnected. Such a unit is considered durable and reliable in operation. This variety is used in non-sleep models.
• Independent type. Complex structures consisting of vertical springs, each of which is dressed in a textile case and does not have a connection with the other. The integrity of the structure is created by connecting textile covers.

Sofas differ not only in the design and type of the spring unit, but also in the transformation mechanism. There are several basic options for folding the sofa with its transformation into a full bed. Sofas can be folding, sliding and mobile.

The most popular transformation mechanisms are:

• "book" - option, folding on the principle of the book (raising the seat until the backrest falls);
• "Eurobook" - Improved "book" (a sofa, the seat of which is pushed forward, and the back is lowered in its place);
• "dolphin" - a popular model with a box that accommodates a sleeping bed mat (the mat moves forward and rises, forming a full-fledged place to sleep);

• "accordion" - a sofa with folding accordion (all three parts are laid out in a full bed if the seat is pushed forward);
• "Click-klyak" - transformation of lifting to the click of a seat (at the same time the back automatically goes down);

• American folding bed - version without a box for linen (unfolds by pulling up the back, lowering it to the floor and further turning the part with the legs);
• french cot - analogue of the American model with removable cushions and a fixed back (transformation "Sedafleks").

All existing models of sofas with spring unit are divided into three groups:

1. straight;
2. corner;
3. modular.

Each type is selected taking into account the dimensions of the room. Direct models are considered universal and fit perfectly not only in a spacious room, but also in a small room.

Corner models are a find when every meter of useful area matters. They are convenient not only the mechanism of transformation and reliable spring unit. Often, these models allow you to change the angle from right to left. The modular system is quite popular and convenient in that it allows you to assemble any model.

Often buying a sofa with a spring block baffles. Typically, 10-15 minutes of inspection of furniture is not enough to assess the quality of the assembly, the mechanism of transformation and the reliability of the springs. Even if we take into account the basic function of supporting the spine and the correct position during sleep, you need to choose the appropriate type of filler:

1. soft - designed for the guest version and does not provide for a constant transformation in order to sleep;
2. optimal stiffness - the standard choice of the majority, calculated on the average weight of a person (taking into account two places);
3. hard - a good preventive option, suitable for children and adults with a sore back.

If we consider the weight load, then the best option is the spring block optimally rigid type. It is most resistant to bending and deformation, more durable. If it is supplemented with layers of coconut fiber, it will also prevent the breakage of the springs.

Models with a clamshell transformation mechanism have a slight drawback. In the unfolded form, they do not always have a flat surface, since their mats may differ in thickness. If a sofa with a spring block is chosen as a bed, it is better to pay attention to such models as "eurobook", "accordion" and "dolphin".

Having decided on the model and dimensions, you have to deal with other issues: which spring unit is more durable, which additions to the filler are better, which upholstery is more practical.

If you choose between dependent and independent spring block, the best choice would be the type in which the springs are independent and independent of each other. Ideally, there are few springs and textile upholstery. It is much better if the mattress is supplemented with coir and a layer of polyurethane foam on both sides.Moreover, it is equally important that a small layer of foam rubber be glued to the sides of the structure.

The construction with the “snake” block will not withstand the maximum and daily loads, it may become unusable after a couple of years of use.

To simplify the selection, you should heed the advice of experts:

• If the system when unfolding is looseThis mechanism will not last even a year, you should not even consider it as a purchase.
• Those who are not used to hard surfaces., it is necessary to choose a sofa with a spring unit of medium hardness.
• The thickness of the block should be from 15 to 19 cmotherwise it will quickly buckle.
• Cheap sofa speaks of a weak transformation mechanism and bad frame.
• Sofas with independent spring block do not replace an orthopedic mattress, but they are much better than other options.

There is a sofa in almost all apartments.In addition to its main purpose, aimed at a comfortable rest, it can decorate and zone the space. For example, in the design of a studio apartment, he may determine the boundary of the recreation area. If you install it in the center of the room, it will allow to delimit the dining area.

A small spring sofa creates the illusion of space, eliminating the feeling of clutter. In addition, it is convenient when moving, can move freely around the room and fits into any room. The greatest harmony can be achieved if the color of the upholstery does not match the tone of the wallpaper or floor. The difference in color of the sofa should be at least two tones.

If suddenly the spring unit is broken, you can replace it or try to repair it (if the model allows). Repair of spring blocks is more difficult than their replacement. It involves disassembling the sofa, unscrewing the sidewalls and backs with a wrench. If necessary, you must remove the brackets that fix the upholstery, and then remove the cover.

If the block is covered with polyurethane foam (dense foam), it is removed, then a visual inspection of the springs is carried out in order to detect damaged (weakened) fragments.Wretched springs unscrew, then in their place put new, bought in a specialty store.

It makes no sense to stretch sagging springs: they will no longer be so elastic, therefore it is also desirable to replace them. After dismantling the foam is glued, then the block is closed with a cover and secured with a furniture stapler.

If the unit cannot be repaired (many damaged springs), it is better to replace it with a new one. You can order a spring block according to individual measurements - depending on the design. Its cost will depend on the material to be filled and the type of springs.
