ABSTRACT:
A seating means formed by a plurality of support units, each one with two kinds of separate chambers connected by free flow ducts; a main chamber filled with liquid, and empty and larger capacity secondary chamber(s). Each support unit corresponds to a specific contact area of the human body. Only main chambers come into contact with the body of the user, receiving the user's weight pushing through the free flow ducts, towards their respective secondary chambers, a volume of liquid equal to the volume displaced by the weight received and wherein an individual control of pressure and flotation is established due to the shape and position of secondary chambers and the density of the liquid contained. The support units are outfitted with independent filling and drainage valves as well as temperature control and leakage control devices.
