It's created from a luxury blend of 60% pure soft cotton and 40% premium polyester, giving it a lovely grip and silky feel. The fabric is carefully woven with a sumptuous 1500 thread count such that the cotton is on the front of the sheet and the polyester is underneath for an easy-care, wrinkle-resistant finish. The Royal Comfort 1500 Thread Count Cotton Rich Fitted Sheet Set is a smooth, pure soft touch that gives you the beautiful cool sensation that only this sheet set can give you.
