ABSTRACT:
A core spring assembly combines the use of rows and/or columns of round coil springs with rows and/or columns of rectangular torsion bar coil springs, all interconnected in a top plane by a welded wire grid so as to create a spring core assembly for a bedding mattress or box spring. In one preferred form, the rectangular torsion bar coil springs are located about the periphery of the spring assembly while in another embodiment the rectangular torsion bar coil springs are all located in the center one-third of the spring assembly so as to increase the firmness of that center section of the unit.
