Different types of springs are installed in upholstered furniture, which differ in properties, parameters and price. Most commonly used:

  1. Orthopedic unit with independent springs. Each spring is inserted into a separate case, and they do not interact with each other. This filling has a high point elasticity, repeats the anatomical features of the body well, correctly distributes the load and provides an orthopedic effect. Independent sofas are comfortable for sleeping and relaxing. During operation, an unpleasant metal rattle is not created, since there is no friction between the springs.Varieties of spring blocks in the couch.

  3. Bonnel. It is a set of tightly interlocked spirals. Accordingly, when you click on one, all the others bend, evenly distributing the load on the entire base of the sofa. Bonnel is a time-tested option. It is soft, comfortable, has a low cost.
  4. Spring Snake. The easiest filler option for upholstered furniture. The spring is attached to the frame, and polyurethane foam or other material with a thickness of at least 0.8 cm is placed on top of it (otherwise the spring will be felt). It is convenient to sit on sofas with a snake, but they are not suitable for sleeping, as the hammock effect is created, and the spine takes an irregular shape.

Features of the spring snake

Features of a spring snake.The block received the name “snake” due to its bending shape. Outwardly, it is a twisted wire on which a filler is laid on top. The number of springs depends on the size of the sofa. Despite the fact that this type of base can be applied to all types of furniture, it is more suitable for those that are not used for sleep.

IMPORTANT! As a material for the production of "snakes" used steel wire with a high carbon content. The thickness of the wire and the density of placement determines the final operational characteristics of the furniture.

The technology for installing a spring snake is very simple. The design is mounted inward or directly on the frame at a fixed distance between the fasteners. A hook is used for fastening - a curved metal plate that provides strength and reliability of the structure. The spring is not susceptible to corrosion and other destructive factors due to high-quality protective coating.

  • long term of operation;
  • good spring characteristics;
  • quick assembly;
  • anticorrosion coating.
