Abstract
A variable spring surface deck and a foundation having a variable spring surface deck thereon. The deck comprises a plurality of longitudinal spring wire support rods which are maintained in a spaced orientation in a planar configuration. They are maintained as such in various structures, such as a mat having a series of parallel slots, or a carrier having spaced, open corrugations. The support rods are located in chosen slots or corrugations. A second, cross-wire layer of lateral spring wire support rods can be included in the variable spring surface deck. The variable spring surface foundation includes the variable spring surface deck located on a top bearing structure of a foundation unit.
