Bed pad support for an invalid

Claim 1

A bed buoyant underbody support for an invalid comprising a rectangular top and bottom sheet of fabric stitched together defining a boundary for said underbody support, comprising 65% polyester and 35% cotton of a 76 inch warp and a 52 inch weft having a weight of 1.83 yards per pound, a buoyant batting filler of a hollow slick polyester batting of 6 denier filaments garnetted into a batting, lines of stitching defining rectangular lines of quilt-like stitching forming an internal set set inwardly from said boundary and having longitudinal and transverse runs joining said top and bottom sheets and defining a channel about the perimeter of said top and bottom sheet, said channel containing air and said bouyant batting filler, transverse quilt-like stitching between the longitudinal runs of said rectangular lines of stitching being set in from the longitudinal runs of said rectangular lines of stitching dividing the internal set of transverse lines of stitching into a plurality of adjacent channels along the major axis of said rectangle and containing air and the buoyant batting filler of hollow slick polyester batting wherein said transverse stitching stops short of the longitudinal stitching of the rectangular lines of quilt-like stitching leaving an opening between the adjacent transverse channels to permit passage of air between channels so that the bed buoyant underbody support is not so rigid as to not provide a resilient buoyant underbody support for an invalid.
