Abstract
A waterbed frame construction comprising a perimeter frame made up of longitudinal and transverse channel shaped frame members which are provided with foam pad cushions along the upper side edges of the frame and the outwardly facing sides of the frame. A slot is formed in the outer peripheral vertical side of the frame to receive a tuck of an article of bedclothing to retain the bedclothing on the bed and covering the sleeping surface of the waterfilled bladder. The frame includes a substructure for supporting the bladder comprising spaced apart longitudinal beam members and a support deck. The frame may be disassembled for transport, is of superior strength due to the channel shaped perimeter beam members, and is adapted to accommodate and retain standard size sheets and blankets. The frame may be suitably supported on a standard bed sub-frame.
