ABSTRACT:
A water bed includes a water-filled bladder resting upon a base having a semi-flexible outer framework providing lateral support for the periphery of the bladder. The outer framework is divided into a lower wedge-shaped portion affixed to the base, and a movable wedge-shaped upper portion resting on the lower wedge and hinged to the base along the inside edge of the lower wedge. The periphery of the water-filled bladder rests against an inclined inside supporting surface provided by the upper wedge. The upper wedge pivots away from the lower wedge toward the bladder to allow access to an elongated open space extending around the outer framework between the wedges. A cushioned cover sheet overlies the bladder, and a flexible skirt extends downwardly around the periphery of the cover sheet. The skirt is fitted into the space between the upper and lower wedges. Fastening means on the skirt are releasably attached to corresponding fastening means between the wedges for applying an adjustable tension to the cover sheet which, in turn, controls the characteristics of the fluid support provided by the water-filled bladder. The space between the wedges also provides room for tucking of bedding, and the normal pressure of the water-filled bladder against the upper wedge holds the tucked bedding in place.
