ABSTRACT:
An improved box spring assembly is selectively reinforced to reduce sagging. The box spring assembly includes a bottom frame with end rails and side rails and a series of cross slats lying across the frame. The box spring assembly incorporates a combination of conventional flat cross slats and reinforcing cross slats, each supporting a number of spring modules of complementary height, giving the box spring uniform height throughout. The spring modules are attached to a grid top, and the grid top and spring modules are enclosed by a fabric cover. By using reinforced cross slats in locations where extra strength is needed and conventional cross slats elsewhere, the improved box spring assembly reduces sagging that could otherwise occur, without incurring the extra cost and weight of using reinforcing cross slats throughout.
