This wonderfully soft and natural cotton mattress pad will protect your mattress and provide excellent cooling comfort at the same time. The secret is breathability - the  cover and fill are both of 100% cotton. Because cotton breathes so well, it doesn't radiate back heat like synthetic pads do. This means a cooler, more restful sleep for you.
