Abstract of the Disclosure A box spring assembly which includes a generally rectangular frame and a plurality of wire springs mounted on the frame and connected to each other so as to yieldably resist downwardly directed bedding loads. Each of the springs has an elongated body portion arranged above the frame and downwardly extending end portions, each of the end portions having a lower column section consisting of a straight length of spring wire and an upper section con- sisting of a plurality of substantially horizontal torsion bars and a plurality of angularly arranged connecting bars connected to and extending between the torsion bars so that in response to a downwardly directed bedding load, the upper section will yieldably collapse to accommodate the load and impart a feeling of soft support to the bedding user. The straight wire column is inclined inwardly so that it can bend lightly and cause a twisting of the tor- sion bar on which it is mounted. This action imparts a feeling of firm support to the bedding user. This combina- tion of initial softness and subsequent firmness is desirable in bedding foundations for purposes of user comfort. In addition, the arrangement of parts facilitates manipulation of stapling tools to secure the mounting torsion bars to the frame.
