ABSTRACT:
A box spring assembly which includes a frame having cross rails, a mattress supporting platform located above the frame and a plurality of spring members mounted on the cross rails in a supporting relation with the platform. Each of the rails has at least a portion of a generally inverted U-shape with a pair of spaced upright webs of predetermined thickness, the webs having pairs of aligned slots each of which has an elongated central section of predetermined width in a vertical direction and end bearing sections of substantially C-shape and reduced width relative to the predetermined width. The bearing sections are of increased thickness relative to the predetermined thickness of the webs, at least some of the springs having mounting foot portions shaped to extend through an aligned pair of slots in the rails so that they rotatably engage the bearing sections at opposite ends of the slots. The result is a box spring assembly in which the springs are easier to assemble with the cross rails and the cross rails provide improved bearing surfaces for the mounting feet on the springs.
