Abstract

An all mechanical support surface that tracks the flotation properties of a true fluid and utilizes a series of constant restoring force springs connecting reciprocating pistons which have supporting surfaces with multiple degrees of freedom to define a user supporting surface that assumes the shape of the user and minimizes the force differential on different areas of the user's skin.
