If you want your bed to be over the top comfortable, this is the mattress pad that’ll make that happen. Our Premium 100% Cotton Quilted Mattress Pads have a premium grade 100% cotton outer shell (top and bottom) and are quilted with a polyester fill in between to maximize airflow between the sleeper and the waterbed mattress. Available in two styles: A flat mattress pad with sturdy 3/4 inch elastic anchor bands in all four corners to secure the mattress pad to the waterbed mattress or a Five-Sided style, which is fitted like a fitted sheet and the sides are made of the same material as the mattress pad itself, with sturdy elastic around the entire perimeter to hold the pad snugly in place.
