A box spring is condensed along its depth dimension and then packaged in this depressed state for storage and/or transportation. At its point of use, the box spring is unpackaged and expanded along its depth dimension for use. Within the box spring are a plurality of support springs movable from retracted, unstressed positions enabling the aforementioned compaction of the box spring, to extended positions which provide the resilient support of the box spring when placed into use. In the preferred form of the invention, the springs are made from spring wire or similar material formed into a sinusoidal shape including generally coplanar wavy or sine portions. The springs are mounted such that movement of the upper support surface of the box spring relative to the base will cause the springs to move into their extended or erect positions to provide resilient support for use of the box spring or to enable the box spring to be depressed into a compact mass for storage or shipment. Releasable means are provided to hold the box spring in its expanded, use position. In the preferred embodiment disclosed, this is achieved through the use of diagonal dies interconnected to and between diagonally opposite locations within the box spring.
