A mattress foundation includes upper and lower frame sections which are resiliently interconnected and supported by a combination of springs and foam. In different embodiments, the springs comprise coil springs, torsion springs, torsion spring modules or a combination thereof. In one embodiment, the foam comprises an elongate piece of foam which extends peripherally around the foundation and envelops or encases the springs. The foam is slitted in a pattern to receive portions of the springs. Alternatively, the foam comprises discrete foam blocks spaced around the periphery of the foundation and between select pairs of adjacent springs.
