ABSTRACT:
An innerspring structure for a mattress comprises a plurality of outer coils extending generally parallel with each other to collectively form top and bottom face surfaces of the innerspring structure. One or more of the outer coils has an inner coil of preferably similar shape positioned generally coaxially with the respective outer coil. In one embodiment, a helical lacing wire wraps together adjacent end turns of the inner and outer coaxially aligned coils to form reinforced coil units in an area of the innerspring structure to increase the firmness of an area of the mattress utilizing the invention. Helical lacing wire connects the coils of the structure together and connects the end turns of peripheral coils to a border wire surrounding the periphery of the structures at the top and bottom face surfaces. In another embodiment of the invention, the structure comprises a row of inner coils and a row of outer coils, each formed from a single continuous piece of wire such that adjacent coils of the row are interconnected by interconnection segments. The rows of coils are positioned together so that the inner coils are coaxial with the outer coils to form reinforced coil unit.
