California King

This all natural sustainable cotton filled mattress pad will protect your mattress and provide excellent cooling comfort at the same time. The secret is breathability. The 240-thread-count 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. Stretch to fit side walls, machine washable, long lasting.
