ABSTRACT:
The present invention provides a mattress cover that is resistant to liquid migration. The cover top has an unbroken surface, that is, a surface without a stitch line or needle holes in that part of the cover which may be subjected to body fluids. In a preferred embodiment, the mattress cover top is secured to a mattress cover bottom by a tooth-type zipper. A bridge strip is bonded to the cover top, and a zipper top component is stitched to this bridge strip. The cover top's edge is folded to form a protective flap, and the zipper top component is also sewn to the upturned portion of the flap, as well as the bridge strip so the bridge strip allows the upturned flap and zipper top component to be connected to the cover's inner side through the bridge strip. When the zipper top component and zipper bottom component are locked together, the protective flap on the top cover overlays both the locked zipper and the stitch line created by stitching the lower zipper to the bottom cover.
