Our Luxury Sheets are made of high strength micro-fiber yarn that remains soft while assuring breathability and comfort. Their extra-fine weave helps protect against dust mite and pet allergens, making them highly suitable for people with sensitive skin. Simple to use, our sheets do not require ironing, dry quickly, and are treated for stain release. The micro-fiber is eco-friendly and 100% recyclable, and fits deep pockets (including newer pillow-top mattresses). All sets include one fitted sheet, one flat sheet, and two pillowcases.
