Enjoy protection and comfort with the Rio Home Fashions Triple Protection Waterproof Mattress Pad. A quiet waterproof back fabric fully protects your mattress, while the stain-resistant and water-repellant top fabric adds extra initial protection that allows you wipe away stains before they set. Sewn with a decorative onion quilt stitch, the 180 thread-count and 100% microfiber fabric cover is super soft. The stretchy skirt fits mattresses from 18 in. to 20 in. deep.
