ABSTRACT:
A variety of pneumatic and other components assembled to afford comfort not found in conventional furniture as follows: a pneumatic cushion exchanging air through a bladder support into two independent bladders where upon depression by persons or other subsequence weight applied to the cushion evenly supports the weight applied. The inner and outer bladder operate independently receiving and compressing air through the cushion and bladder air transfer valves. This independent action allows frontal support when weight is applied to the frontal areas only. In addition to the frontal support a molded plastic material termed herein as the bladder support having memory after thermal molding offers additional front support when weight is applied. When weight or a person is fully seated both bladders are expanded as the air is expelled from the cushion through two air valves serving each of two independent bladders offering uniform seating support. The supporting structure for the bladder support, bladders, and cushion being a composite substrate with properties allowing a depression value allowing additional flex when weight is applied.
