The unique shoulder recess is designed specifically for side sleepers and helps to cradle the head while supporting the neck. Known to induce sleep, this relaxing scent comes infused in the pillow. Our included 2 ml spritzer allows you to refresh the aroma when needed. The premium Tencel™ mesh cover works with the scent instead of blocking it. Our memory foam is free of harsh chemicals and is CertiPUR-US certified. This pillow is backed by a 5-year warranty.
