Compressible foam foundation for mattress support

A foundation for supporting a mattress, comprising:

• a foam block comprising a top side, a bottom side, a head side, a foot side, a pair of side edges, a lateral width, and a longitudinal length, wherein the head side and the foot side are separated by the foundation length, wherein the pair of side edges are separated by the lateral width, wherein the foam block further comprises a flexible foam material having an indentation force deflection greater than thirty-nine pounds and less than ninety-five pounds, wherein the foam block has a compressed configuration and an expanded configuration, wherein the top side and the bottom side are separated by a first thickness of the foam block in the compressed configuration and a second thickness of the foam block in the expanded configuration, and wherein the second thickness is greater than the first thickness;
• a plurality of crosswise supports connected to the bottom side of the foam block, wherein each one of the crosswise supports has a longitudinal dimension approximately equal to at least one of the foundation length, the lateral width of the foam block, and any longitudinal dimension between the foundation length and the lateral width, wherein the crosswise supports extend along one of the lateral width and the longitudinal length of the foam block, and wherein at least one pair of adjacent crosswise supports are spaced apart at a distance greater than the second thickness of the foam block in the expanded configuration and less than the lateral width of the foam block;
• a plurality of legs connected to an underside of the plurality of crosswise supports, wherein a first set of legs are situated proximal to the head side of the foam block, wherein a second set of legs are situated proximal to the foot side of the foam block;
• a plurality of braces respectively connected between a pair of legs from the plurality of legs and the underside of at least one crosswise support;
• and
• a cover enveloping the foam block and a vacuum-seal plastic membrane encasing the foam block and the cover when the foam block is in the compressed configuration forming a packaged foundation and a shipping container having an interior space, wherein the packaged foundation has an opened arrangement and a folded arrangement, wherein the foam block has a planar form in the opened arrangement, wherein one of the head side and a longitudinal side edge in the pair of sides and one of the foot side and another longitudinal side edge in the pair of sides of the foam block overlap a center section of the foam block in the folded arrangement, and wherein the packaged foundation in the folded arrangement, the plurality of crosswise supports, the plurality legs and the plurality of braces fit in the interior space of the shipping container.

• a cover enveloping the foam block;
• a vacuum-seal plastic membrane encasing the foam block and the cover when the foam block is in the compressed configuration forming a packaged foundation, wherein the packaged foundation has an opened arrangement and a folded arrangement, wherein the foam block has a planar form in the opened arrangement, and wherein a center section of the foam block is overlapped in the folded arrangement either by the pair of side edges or by the head side and the foot side;
• and
• a shipping container having an interior space, wherein the packaged foundation in the folded arrangement fits in the interior space of the shipping container.
