ABSTRACT:
A foldable bed is movable between an unfolded position, in which interconnected seat, cavity, and body sections are substantially horizontally aligned and of substantially uniform depth, and a folded position, in which the body section is horizontally disposed, the seat section is horizontally disposed and overlies said body section, the cavity section is generally upright and extends between the body and seat sections. In the folded position, the seat section of the mattress is collapsible, and the cavity section of the mattress is noncollapsible. The bed frame can include a leg that is spaced away from the frame in the folded position that compresses a mattress head section, thereby forming a space within which collapsible springs of the seat section can reside. The bed can include springs having upper, intermediate, and lower runs, wherein the upper and lower runs include offset portions extending in opposite directions that are generally orthogonal to a plane defined by the spring intermediate run. The bed can also include grid wires to which such springs are interconnected that have rotation-limiting means that interact with the offset portions of the spring. Also disclosed is a mattress which is configured with a reinforcing structure having differential rigidity so as to resist force in the horizontal direction but compliantly yield in the vertical direction.
