A four-piece King set in 100% TENCEL™ Lyocell, made from eucalyptus fibre in a closed-loop process. The flat sheet is 105″ x 102″, the fitted sheet 78″ x 80″ with a 16-inch pocket, and the two king pillowcases are 20″ x 40″. What you notice first is the hand-feel: fluid, cool and closer to silk than to cotton. That comes from the fibre, not a finish. Lyocell wicks moisture to the surface instead of holding it against your skin, so the sheet stays dry through the night, which is the part that matters if you sleep warm. The fitted sheet has elastic all the way around plus a corner strap at each corner, so it stays tucked on a deep mattress or one with a topper. Machine wash gentle, cold or warm, tumble dry low, no bleach or dry cleaning. It resists shrinking, fading and pilling, and gets softer with each wash.
