ABSTRACT:
A waterbed comprising a foundation having a rigid horizontally extending base and a rigid support member of substantially rectangular cross section fixed on the periphery of the upper surface of the base and substantially laterally completely enclosing a space on the base; a fluid-filled mattress of greater height than the height of the support member resting on the base in the space within the support member; and an annular cushion interlocked between the sides of the mattress and the support member. The annular cushion includes an upper portion resting on the top surface of the support member, a lower portion resting on the base and against the interior face of the support member, and an integral flexible connection between the upper and lower portions for enabling the upper portion to be pivoted away from the top surface of the support member for insertion of the edge of bedclothes therebetween. In a preferred embodiment, the annular cushion includes a restraining member of L-shaped cross section secured to the upper and lower portions across the flexible connection.
