It is disclosed a system which -when multiplied or placed in a side-to-side arrangement, in planar or not construction- can create in reclining and sitting means orthopaedic body positions, since the invented system has the ability to be anatomically adapted to the human body with the assistance of the foamy materials and discs provided. So, the invented system is composed of elastic fabric having pleats 1 and containing foamy materials (2,3), and of small-surface discs 4 capable of taking the shape (relief) of the human body; said discs are supported by selectable metal spiral springs (5,6 or 5,15) creating at each contact point a body weight-retaining balancing force corresponding to that received by each small-surface disc 4 separately. |
