  • Patent number: 7174583
    Abstract: A height-adjustable mattress assembly is constructed of a mattress foundation and an optional frame assembly with a plurality of ground support members supporting the mattress foundation. The ground support members can be attached to the frame assembly in at least two orientations so as to maintain the top surface of the foundation above ground in a substantially horizontal orientation at at least two different heights. The mattress foundation can be made of two mattress foundation members that are spaced apart by spacer members. The mattress foundation members can be oriented with respect to each other so as to provide a combined height that is adjustable. By combining the adjustable ground support members with the assembly having two mattress foundation members, adjustment at three or more different heights is possible.
