Abstract: A mattress elevating device is composed of components easily and quickly assembled and disassembled without the use of tools, the components being suitably sized for packing and transporting in a suitcase. The components comprise a pair of panel members releasably secured together to form a substantially flat mattress supporting surface and elevating means releasably mounted on the bottom of one of said members for holding the panels in an upwardly inclined raised position. The panel members are substantially rectangular in shape and of the same size and are arranged with adjacent edge portions thereof in overlapping relationship. Bolts and wing nuts are used to releasably secure the panel members together and a cross member is attached to the bottom of the top panel member and forms therewith an elongated groove for receiving the underlying edge of the other panel member and preventing movement thereof away from the bottom of the top panel member.
