ABSTRACT:
A box spring assembly which having a frame, a plurality of upwardly extending wire springs mounted on the frame and a wire deck supported by the springs so that the deck and springs cooperate to yieldably resists downwardly directed bedding loads. Each of the springs has a body comprised of a pair of side-by-side yieldable portions connected at their upper ends by a mounting bar. The yieldable portions include an upper column section and a lower column section connected by a middle section. The middle section is configured to bend in a substantially vertical plane in response to the downwardly directed load. Mounting feet extend from the lower ends of the yieldable portions and enable securement of the spring to the frame. The use of bending stresses in the springs to resist the bedding load produces a spring which stimulates a non-spring system in effective firmness while improving deformation resistance under normal abuse conditions.
