The classic look and incredible comfort of cotton is available at the price of a blend. Instead of blending yarns before the weaving process, all cotton strands are lined up in one direction and poly strands woven across them for a two-sided design with the feel of pure cotton on one side and the wrinkle-resistant convenience of polyester on the other. Make the bed with the cotton sides facing each other for the soft, cozy feel of cotton against the skin. The Universal Fit design ensures sheets have a smooth, secure fit on any mattress.
