ABSTRACT:
The mattress foundation apparatus includes a flat continuous upper component from which downwardly depend a pair of end walls and a pair of side walls. A continuous raised rim about the upper perimeter of the flat upper component retains the mattress in its desired position. A series of solid lateral struts are integrally formed with the upper component and depend downwardly therefrom. The entire mattress foundation apparatus constitutes an inelastic, downwardly opening, hollow structure useful for persons with back or orthopedic problems.
