ABSTRACT:
A stool seat includes an impermeable top wall having an upper surface upon which a user sits and a peripheral edge. The top wall is sealingly joined along its peripheral edge to an impermeable bottom wall and is adapted to support itself in spaced relation above the bottom wall so that the top wall is suspended above the bottom wall from its peripheral edge to provide a single sealed cavity containing a fluid at a predetermined pressure between the top and bottom walls. The top wall is further adapted to resiliently deflect toward the bottom wall under the weight of the user so that the pressure of the fluid in the sealed cavity is increased when the user sits upon the upper surface.
