<p>An all mechanical support surface (30, 48) that tracks the flotation properties of a true fluid and utilizes a series of constant restoring force springs (14, 49) connecting reciprocating pistons (10, 40) which have supporting surfaces (26, 27, 48, 60, 66) with multiple degrees of freedom to define a user supporting surface (30, 48) that assumes the shape of the user and minimizes the force differential areas of the user's skin.</p> |
