Abstract A mattress or cushion support comprising an injection-molded plastic mat or netlike fabric provided along its side and end edges with integral tie means for speedily yet effectively connecting same to the frame of a bed, folding cot, chair, chaise longue and the like. The plastic mat may be formed as a one-piece grid having length and width such that it provides the complete support, or it may be formed in plural, i.e., two half-length, sections which are secured together along a transverse meeting line (or lines) as by metal clips.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
149 words
A mat for supporting a mattress, cushion and the like from the parallel spaced-apart side and end rails of a supporting framework comprising: an injection-molded plastic grid composed of a plurality of longitudinal strands joined in spaced-apart relation by a plurality of spaced-apart transverse strands, and further including a plurality of tie means disposed at regularly spaced-apart intervals along the lengths of and which extend relatively outwardly from the longitudal strands and at least the one transverse strand, respectively, which define the side margins and at least one end margin of the grid proper, the tie means which extend from the longitudinal side-margin defining strands comprising integral extensions of said transverse strands, of which the extensions of each two adjacent transverse strands converge on one another and merge into a straightwayextending tie strap having length requisite to its forming at least a partial securing wrap about a framework rail.
Claim 2
Dependent Claim
