Ideal for softness lovers and snuggle fans. Buttery smooth softness that gets better with every wash. Our Luxe Sateen sheets start with the highest quality threads ('cause thats what you deserve), using 480 thread count long-staple cotton with a one-yarn-under and three-yarn over weave. This means more thread surface is exposed, giving our Luxe Sateen its signature silky-soft feel and luminous sheen. Sateen is more tightly woven, which means you get a warmer, incredibly soft sheet that's ideal for year-round comfort. OEKO-TEX® certified for chemical safety The details that make your life easier: Keep your pillows secure with our pillowcase envelope closures No sweat bed-making with “Long” and “Short” side tags on our fitted sheets Core sheet set includes: flat sheet, fitted sheet, and 2 pillowcases
