Spring system is restored instantly. Learn mark applied foam. Inside, imported furniture you would not say (because they do not know).
But domestic manufacturers must know what kind of foam he uses to manufacture its furniture. The higher the density – the better. Longevity depends on the density of foam. Minimum density foam used for seats – 35. Mechanisms. Mechanism should be decomposed easily and smoothly, without jamming.
Carefully inspect the quality of manufacturing of metal parts of the mechanism and coating quality. Sela Ward brings even more insight to the discussion. Frame. Try to lift a sofa or chair. If you manage this, perhaps, the framework of this furniture is made of wood or plywood. Otherwise, the frame is made of particleboard. Highest quality option – a frame made of plywood.

Jacquards and tapestries – basic furniture fabrics with a dense weave threads (high durability and longevity). Shenily – above fabrics with interwoven thread "shenil" that gives the volume of tissue.

If your hands that you have a nylon particles (for flock), or tissue diverges or has a rare weaving – is bad. Price – one of the indicators of quality fabric. Good fabric can not cost less per square meter. Important stuff Pay attention to detail. You can not know what kind of foam, frame and fabric used by the manufacturer. But, if he: did not close the back part of the same fabric as the front (still do not visible if standing at the wall), not put back fiberboard (cloth stretched on the frame) is not compatible drawing tissue is rarely (distance more than 5 cm) filled staples (save 10 cents), was unable to qualitatively prostrochit cover (uneven line, missed stitches), then that inside the sofa – it is easy to guess.
