ABSTRACT:
A bedding foundation unit having a top planar portion defined by two pluralities of spaced parallel grid wires, and a rigid frame spaced apart from the top planar portion by a plurality of modular springs. Each modular spring is formed from one piece of wire and has a top section, two vertical legs and two foot sections, with each of the vertical legs having at least one arcuate portion. The top section of most, if not all, of the modular springs extend longitudinally of the foundation and are connected to the top planar portion in a snap-fit manner, each top section of each modular spring being held in place by three grid wires and one grid wire below the top section.
