ABSTRACT:
An improved variable contour cushion operating system comprising an imperforate flexible casement containing myriad amounts of tiny spherical plastic micro-bearings which displace in response to an occupants body weight during an equalized atmospheric-pressure mode of use, but respond enmasse to an induced low-pressure air differential condition by fixing to an instant position through virtue of said micro-bearings deforming temporarily into inter-joining polyhedrons; wherein said casement in this new disclosure is additionally subjected to a "floative"-mode of operation involving positive air-pressure greater than former ambient-atmosphere, thus achieving an enhanced cradling effect in the "contour"-mode for greater comfort & security to the occupant.
