MOLECULE Sateen Sheets are luxuriously drapey and smooth. Sateen is a weave woven tightly, thus creating a heavier, perfect year-round sheet. It is comparable to the feel of silk, but with more durability leading to many years of comfort and better sleep. Its smooth, buttery feel is a constant reminder of luxury and comfort at its pinnacle. MOLECULE sheets are OEKO-TEX® certified and designed with advanced TENCEL™ materials that keep you dry and cool, reduce bacterial growth, and help you discover healthier sleep.
