Abstract
Mattress-chair, which is essentially characterized by comprising a volumetric sheath, flexible nature, closed on itself, whose bottom is the one that rests on the floor, and whose shape forms when sitting the user a large anterior concavity that extends without solution of continuity upwards, as a previous part of a general elevation, in such a way that in the space as a created shell the body of the user is collected, which enjoys full and homogeneous softness, due to the fact that the cover is filled of preferably spheroidal portions, suitably elastic, which are introduced through the opening controlling a rack arranged in a lower position, and optionally, for the interior ventilation, several perforated brackets exist.
