It takes more than a high thread count to create truly superior bed sheets. Case in point: our sumptuous 400-count Supima sateen bedding. Supima is a rare American cotton - just 3% of the U.s. crop qualifies. It takes this bedding from silky to positively indulgent - and makes sleep serene. Our gentle No Iron finish lets you take your bed sheets from the dryer to the bed without a wrinkle. Twin and Extra Long Twin sheet sets include: one pillowcase, fitted sheet, flat sheet. Full, Queen and King sheet sets include: two pillowcases, fitted sheet, flat sheet. Pillowcases: set of two.
