Using your Weekender Tencel Lyocell sheet set is a breeze. Simply slip the fitted sheet over your mattress. The elastic on the deep pockets will keep it in place, even on mattresses up to 18 inches deep. Then lay the flat sheet on top and add your pillowcases. For a cozy night's sleep, you're all set! When it comes to maintenance, machine - wash these sheets in cold water on a gentle cycle. Use a mild detergent. Avoid using bleach or fabric softeners as they can damage the Tencel™ Lyocell fabric. Tumble dry on low heat. Once dry, you can iron them on a low - heat setting if needed. Store the sheets in a cool, dry place when not in use to keep them in top condition.
