Selectively elevated foundation for a mattress

A mattress foundation having a length and a width, comprising:

• (a) a first frame end assembly and a second frame end assembly, the two end assemblies having a width corresponding to the width of the foundation, each end assembly having a pair of opposite ends and a pair of end-to-side beam assemblies perpendicularly extending from each opposite end, the end-to-side beam assemblies having a length that is less than one-third the length of the foundation;
• (b) a pair of side beam assemblies, each side beam assembly extending in a lengthwise direction with respect to the mattress foundation, each side beam assembly having a pair of opposite ends, and each of the opposite ends being selectively connectable to a respective end of an end-to-side beam assembly;
• (c) a plurality of connectors of molded plastic material having a length, opposing ends and a channel extending through the length, the channel being wide enough at the ends to incorporate each end of each side beam assembly to a respective one of the frame end assemblies;
• (d) a plurality of transverse mattress support members each having a narrow surface, a wide surface in relation to the narrow surface, a length and a pair of opposite ends, where the support members extend between the side beam assemblies parallel to the foundation width, the narrow surface facing upwards so that the support members significantly resist bending downwardly under the weight of a person on a bed including the foundation, where the bending strength from the support members makes it unnecessary for the foundation to have a central longitudinally extending beam located in the center of the foundation and parallel with the length of the foundation;
• (e) a plurality of hangers having a pair of parallel side members, a back member, and a bottom member, the side members and bottom member extending perpendicularly from the back member forming a pocket that is open upwardly and toward the interior of the foundation frame, in which to receive the end of a mattress support member, where the side members are trapezoidal in shape and wider at the bottom of the hanger so that the pocket is deeper at the bottom of the hanger;
• and
• (f) an elevation component of a molded plastic material having a height and a width, the width corresponding to the width of the pocket of the hanger, where the elevation component is used to support and raise the transverse support members.
