A floatation sleep system including an improved marginal perimeter support containment chamber of relatively simple construction assembled by a relatively inexpensive manufacturing process. The improved marginal perimeter support containment chamber comprises a flexible, dimensionally stable, sheet having a surface area of substantially rectangular shape with portions extending outwardly from the marginal edges of such surface area. The portions are folded back and joined to the surface area within the marginal edges thereof to form a cavity adapted to receive a bladder and a support mechanism for substantially the full perimeter of a bladder received within such cavity. The dimensions of the area bounded by the joining of such portions to the surface area are less than the corresponding surface area of the received bladder, whereby the received bladder overlies a segment of such portions and the weight of the bladder acts on such segments to hold the support mechanism in effective perimeter support relation with such bladder.
