Abstract
A box spring assembly for use as a foundation for a bedding mattress has a triple beam frame. The frame has three layers of which the bottom layer consists of longitudinal side rails equally spaced from a center rail and connected at each end to a double thickness end rail consisting of a lower and upper board. The middle layer of the frame includes a number of transverse slats equally spaced between the upper board end rails positioned at each lengthwise end of the box spring assembly. The lower board end rails underlie the upper board end rails and are in the bottom plane of the frame. The top layer of the frame consists of longitudinal slats spaced atop the transverse slats and upper board end rails. The triple beam frame is constructed of metal, wood, or a combination thereof. Coil springs are secured to the longitudinal slats in the box spring assembly. The longitudinal slats provide additional support and resistance to bending or deformation at the foot and head end of the box spring assembly, particularly if the foot end of the bed is unsupported by the bed frame. The provision of the longitudinal slats in a third layer of the wooden frame also provides a higher profile for the box spring assembly.
