ABSTRACT:
A bedding or furniture spring product comprising a plurality of coil springs arranged in linear rows and columns. Each of the coil springs is preloaded by an endless strip of fabric, the strip of fabric encircling the exterior of one of the coil springs. The interior surface of the strip of fabric may be coated with a non-slip material so as to prevent the strip from falling or moving off the coil spring. Alternatively, the coil spring itself may be coated with a non-slip material. The strip of fabric leaves a portion of the end turns of the coil springs uncovered enabling the coil springs to be secured to a wire grid as for example by being wrapped around or clipped or laced to wires of the grid assembly. Alternatively, traditional hand 8-way tie may be used to connect the precompressed coil springs together and to a frame.
