The Merida Lyocell Satin Duvet Cover Set creates a smooth, cool sleep surface that feels comfortable night after night. Made from TENCEL Lyocell in a 400 thread count satin weave, the fabric has a naturally silky hand that glides softly without feeling heavy. This sustainably sourced fiber is breathable and helps regulate temperature, keeping you cool when it is warm and comfortable when it is cooler. The fabric is OEKO-TEX STANDARD 100 certified, tested against more than 350 harmful substances. The duvet cover features a discreet button closure with a flap at the foot end and interior corner ties to keep the insert in place, and its reversible solid design makes styling easy. This three-piece set includes one duvet cover and two shams: the Queen set includes two Standard shams and the King set includes two King shams.
