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.
