ABSTRACT:
The present invention relates to a spring assembly for the seat portions or areas of upholstered furniture. The spring assembly provides a frame and a series of different spring types supported in a generally parallel arrangement within the frame. The spring assembly inlcudes a plurality of upper spaced, elongate sinuous springs extending between and above a pair of opposing front and back members. Located in the central region of the assembly is a rectangular quad coil spring mounted on two upper and lower wire stringers. The spring assembly is provided with a pair of Z-shaped sinuous springs, one located on each lateral side of the quad coil. The Z-shaped springs are mounted on lower elongate sinuous springs extending between the front and back members. The upper portions of the Z-shaped sinuous springs and the upper elongated sinuous springs are secured to the upper and lower stringers for stability and to prevent lateral movement of same. The Z-shaped springs provide for local support independent of the central quad coil. The spring assembly provides a differential response across the top surface thereof in response to a user sitting thereon. When several such assemblies are mounted adjacent one another, the resulting system provides for relative independent spring support between adjacent users.
