Abstract: A box spring assembly which includes a generally rectangular frame and a wire spring assemblage mounted on the top side of the frame; the assemblage including a large number of straight wires arranged criss-cross fashion and arcuate springs that support and connect the straight wires at some of the points of intersection. A basic wire grid is formed with downwardly extending hook portions that snap over some of the spring wires to secure the grid to the assemblage so as to bridge the spaces between the straight wires. The "spring back" capability of the spring wires allows them to spring into the hook portions so as to retain the grid in position.

As a result, a uniform spacing can be maintained between the bands across the entire seat frame.

Abstract: A box spring assembly which includes a generally rectangular frame and a plurality of wire springs mounted on the frame and connected to each other so as to yieldably resist downwardly directed bedding loads. Each of the springs has an elongated body portion arranged above the frame and downwardly extending end portions, each of the end portions having a lower column section consisting of a straight length of spring wire and an upper section consisting of a plurality of substantially horizontal torsion bars and a plurality of angularly arranged connecting bars connected to and extending between the torsion bars so that in response to a downwardly directed bedding load, the upper section will yieldably collapse to accommodate the load and impart a feeling of soft support to the bedding user. Subsequently, the straight wire column carries the bedding load and imparts a feeling of firm support to the bedding user.

Abstract: A box spring assembly which includes a generally rectangular frame, a plurality of wire springs mounted on the frame and connected to each other so as to yieldably resist downwardly directed bedding loads. Each of the springs has an elongated body portion arranged above the frame and downwardly extending end portions, each of the end portions having an upper section and a lower section which are located in planes that are upright and generally perpendicular to each other with each of the sections being comprised of integral legs arranged in a generally V-formation rotated about ninety degrees and with the included angle between the legs being less than ninety degrees. This construction enables the spring end portions to yieldably resist bedding loads with both bending and torsional stresses thereby enabling increased load-resisting capabilities in the spring end portions with a resulting efficient use of spring wire material.

Abstract: The sleep unit includes a base upon which is mounted a single set of springs. These springs are overlaid with cushion material. The springs are leaf-type springs having a curved configuration. The spring action is such that the resistance to deflection increases with increased load. Thus, the sleep unit has an initial softness followed by increased firmness depending upon the weight of the user. Means are provided to permit pre-compression of the springs to vary the initial firmness of the sleep unit.

The cushioning elements may be thick foam housings that cover at least the upper surface of the cross rails or sinuous wire springs that extend along the length of the cross rails. The cross rails themselves preferably have a limited degree of flexibility so as to better withstand high impact loads.
