The sides, also made from organic cotton sateen, have deep, 15 inch pockets and elastic around the bottom for fit. We consider an organic cotton mattress pad the essential accessory to every mattress. Not only does it protect your mattress, but it also allows you to wash away any dust and perspiration that may go through your sheet. This fitted organic mattress pad is an ideal option for most people and it works perfectly in combination with a wool moisture pad if you need further protection from moisture. All of the cotton used in this mattress pad is 100% organic--sourced and woven in India. Machine wash and dry.
