SPRING ASSEMBLY

A box spring assembly including a generally rectangular frame with a first plurality of spring members extending transversely between the sides of the frame and spaced from one another longitudinally of the frame. Each spring member is defined by an integral wire having a straight load section and a fishmouth section at each end thereof. The spring members are disposed in pairs overlapping one another transversely of the assembly. The particular improvement is the disposition of pairs of undulations in the straight sections of each spring member so that the spring members may be positioned or aligned longitudinally of one another by disposing a clip about the straight sections between adjacent pairs of undulations.
