Abstract

A cushion with a support pad comprising a plurality of compressible suspension elements with a cover top and bottom joined together to form an impervious barrier, and a valve in fluid communication with the plurality of compressible suspension elements that allows the controlled expulsion of air until a user positioned on the cushion is optimally immersed in the cushion. When the user is removed from the cushion, the valve allows ingress of air into the cushion. In one aspect, the valve comprises an expansion valve controls air flow out of and into the cushion. In one aspect, the valve comprises a labyrinth seal that dampens air flow and pressure spikes. The valve comprises a pressure responsive compression spring that controls the expulsion of air from the cushion and, consequently, adjusting the immersion depth of the seated user.
