Abstract

A wire spring module and wire grid for use in a furniture spring assembly for mounting an array of multiple spring modules to the wire grid and the resulting furniture spring assembly. The wire grid includes a plurality of straight, coplanar wires arranged in a first sub-plurality of parallel spring placement wires and a second sub-plurality of parallel spring seating wires extending in generally perpendicular relation to the spring placement wires, the spring seating wires being arranged in a plurality of seating wire pairs with the spring seating wires of each seating wire pair disposed at a first predetermined spacing from one another and with each seating wire pair disposed at a second greater predetermined spacing from each seating wire pair adjacent thereto. The unitarily-formed wire spring module comprises a generally coplanar top and a pair of legs extending from opposite ends of the top and in spaced relation to one another. The top is comprised of a pair of generally J-shaped end segments arranged in spaced reverse mirror image relation to one another and connected together by an intermediate straight segment. The intersection points between each J-shaped segment and the intermediate segment form an angular relation therebetween. The wire spring module can be connected to the wire grid in two alternate positions. A furniture spring assembly comprising the disclosed wire grid with wire spring modules connected in either of the two alternate positions is also disclosed.
