ABSTRACT:
Mechanism for maintaining the shape of a floatation sleep system, such system including a bladder having flexible walls defining a chamber adapted to be filled with fluid and a marginal perimeter edge support for such bladder. The shape maintaining mechanism comprises a sheet of flexible, dimensionally stable material. The sheet is attached to the underside of the bladder along a substantial portion of opposed marginal edges so that it extends, in intimate contact, from one edge, around the adjacent marginal perimeter support, across the top portion of the bladder, around the opposite marginal perimeter support to the other edge. Such sheet is thus constrained to oppose the fluid forces on the marginal perimeter support and maintain the shape of the floatation sleep system.
