Two-sided weave design creates a soft cotton side and a wrinkle-resistant poly side. Deep pockets and oversized dimensions for mattress depths up to 18". Universal Fit® design with thick elastic for a smooth, secure fit. Sheet sets or pillowcase sets available in four colors. 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.
