## 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.

## Claims
