Abstract: A spring wire support for foundations and innerspring mattresses, and a variable spring surface deck for a foundation and variable spring surface for a mattress. The spring wire support comprises an elongated spring element enveloped in a pliant carrier, with the carrier including an attachment margin. The variable spring surface deck for a foundation comprises a plurality of the spring wire supports secured as desired to an upper surface of a foundation. The variable spring surface for a mattress comprises a plurality of the spring wire supports located between top and adjacent convolutions of rows or columns of springs of the mattress.

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.
