Abstract
Abstract A box spring assembly including a wooden frame with a plurality of spring members arranged on the frame to define a loadsupporting area having side and end marginal edges. Each of the spring members is defined by an integral wire having a straight section with a fishmouth section at each end thereof. The spring members are disposed with the straight sections thereof perpendicular to the side marginal edges, and each spring member is disposed in isolated non-contacting relationship with all of the remaining spring members. Various species are illustrated showing the individual spring members in various patterns; but in each pattern, each of the spring members is isolated and not contacting any other spring member. Connecting means such as wires or grids are utilized for interconnecting the spring member.
