Abstract
Abstract A multilayer supplemental support pad includes a generally planar layer of foam surrounded by fabric material. Lateral stitching forms channels in the pad to facilitate rolling up of the pad for storage and transportation. Elastic straps secure the rolled up pad. Other straps may be used when the pad is unrolled to secure the pad to a chaise lounge or other support surface. Different types of fabrics and pads of different dimensions may be used to provide pads for alternative purposes. When used as a chaise lounge pad, an approximately one-half inch thick layer of foam cut into a twenty inch by seventy inch rectangle is preferred, with cotton terry cloth fabric on at least one side of the pad. Fabric edging stitched to the periphery of the pad reinforces lateral edges of the main stitching.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
168 words
A portable support pad, comprising: an integral foam member comprising a generally rectangular shaped planar layer generally of a predetermined, constant thickness in a range from about one-fourth of an inch to about one inch thick; fabric coverings received on both sides of said foam member layer and received about the edges of said layer so that said foam member is fully encased; generally straight-line stitching through said pad at spaced intervals therealong so as to secure said fabric coverings to said foam member, said spaced intervals being generally no greater than about two and one-half inches, and said spaced stitching extending laterally relative said generally rectangular shaped foam member layer so that said pad may be rolled up in a longitudinal direction perpendicular to the direction of said stitching; and elastic strap means comprising at least one integral loop secured at one end of said pad and functional when said pad is rolled up for surrounding said pad and elastically maintaining same in such rolled up condition.
