Abstract A sheet of flexible material is folded and seamed into a contour mattress cover which lies flat for storage and may be formed as a continuous ribbon of detachable, end to end connected covers wound into a roll or may be individually interleafed in a pop up arrangement in a box or other dispenser. A flexible sheet comprising a fluid impervious, thermoplastic foundation layer laminated to an absorbent layer has its relatively longer opposite sides folded back onto its non-absorbent surface to form inwardly opening pockets. Longitudinally spaced, heat sealed, transverse seams, which are shaped to correspond to the opposite ends of the mattress, connect interfacing layers of the folded sheet for closing the ends of the pockets.
A plurality of end to end detachable contour mattress covers comprising: a flexible ribbon sheet having its opposite sides folded back onto the same surface of itself and having longitudinally spaced transverse seams connecting interfacing layers of said sheet to form and close the ends of a plurality of inwardly opening pockets, said transverse seams being alternately separated by a relatively short perforated segment and a relatively long segment, said seams further being rounded in correspondence with the shape of the ends of a selected mattress and wherein the length of said long segment is substantially equal to the sum of the length and the thickness of a selected mattress and wherein the width of said folded sheet is substantially equal to the sum of the width and the thickness of said mattress.
