The Mattress Pad with Wings surface is soft and comfortable while protecting from wetness. It is complete with large, fabric wings to help secure the pad in place. It is washable and reusable making it far more economical than disposable bed pads used for incontinence. This is a specially designed, reusable, and washable mattress pad that ensures protection for you or your loved one and the bed! The bed pad is 36 inches by 34 inches with three layers of protection. The 18 inch long wings attached to either side of the bed pad are long enough to tuck under one side of a bed or both (if twin or hospital type bed). The wings tuck under the mattress and prevent the pad from slipping or moving. The top layer of the bed pad is made from an 80/20 cotton/polyester blend called IBEX. This top layer is quilted to a top quality, 8 oz poly soaker which holds the moisture. The third, and bottom layer, is the moisture proof layer; it is made from a knitted, vinyl, barrier fabric. The bed pad is finished with double bound edges for a long life of many washings. This amazing mattress pad will hold up to 60 ounces of liquid.
