Claim:
1. A bed foundation having a rectangular configuration comprising: two opposing elongated side rail structures, wherein each side rail structure has a longitudinal axis, is substantially rectangular in cross section and has vertical inner and outer sides, top and bottom horizontal edges, opposing head end and foot end portions, and a slat supporting intermediate section extending between said head and foot end portions, wherein each said intermediate section has a plurality of rectangular in cross-section pocket recesses formed into said inner side at longitudinally spaced locations along said intermediate section wherein each pocket recess has a horizontal top wall, a horizontal bottom wall, opposing vertical side edge walls, an inner wall, and a lateral axis and wherein each side rail has a plurality of passages formed laterally through said intermediate section, wherein said head and foot end portions of each said side rail structure are connected respectively to end portions of a head board structure and a foot board structure, wherein said inner sides of said rail structures face toward each other; a plurality of elongated bed slats each having rectangular in cross-section end mounting portions which allow a sliding fit of said end mounting portions into said pocket recesses, wherein each said end mounting portion is positioned in said pocket recesses; a plurality of nut wells, wherein each nut well of said plurality of nut wells is formed vertically down through an associated one of said top horizontal edges, is associated with and extends vertically downward through an associated pocket recess of said plurality of pocket recesses and through one of the end mounting portions of an associated slat of the plurality of slats and further down into the bottom wall of the associated pocket recess to provide top and bottom stop shoulders on each nut well; a plurality of nuts each having a threaded bolt receiving bore, wherein each nut is positioned in an associated nut well of said plurality of nut wells; and a plurality of bolts each having a longitudinal axis, wherein each bolt of the plurality of bolts is mounted through a corresponding passage of said plurality of passages from said outer side through said inner wall of a corresponding pocket recess of said plurality of pocket recesses and into said corresponding pocket recess and further into one of the end mounting portions of an associated slat of the plurality of slats positioned in said corresponding pocket recess substantially along said lateral axis of said corresponding pocket recess, wherein said bolts extend horizontally through said inner walls of said pocket recesses and through said threaded bolt bores of said nuts, whereby upon tightening of said bolts said slat mounting ends are drawn into said pocket recesses toward said inner walls of said pocket recesses to thereby strengthen and rigidify said bed foundation.
