100% Cotton Mattress Cover With One-Side Zipper Opening
This high-quality mattress cover is made of very soft 230 thread count 100% cotton fabric. It is machine washable and may be machine dried for easy care. Fits up to 4 inches of latex layers . Zippered closure opens on one side only. Comes with 5-year manufacturer's warranty.
Note that the length and the width are measured from seam to seam if cover is laid out flat. Because these covers are constructed with no border or gusset, just like a normal pillow case, the specified lengths and widths are longer than the dimensions of your foam to allow for the thickness. The Twin size zippered case (43x81), for example, should fit up to 38" x 75" x 5" foam.
