We manufactured this mattress pad with top quality materials. It has a soft 1/2" top and 100% polyester fiberfill. Will snugly fit standard crib mattresses up to 5 inches thick. We sew strong elastic all the way around the bottom so the mattress pad stays on the mattress. CRIB or TODDLER size 28X52, Machine Washable
