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. Split King sheet sets include: two pillowcases, two XLT fitted sheets, one flat sheet. Pillowcases: set of two. *Monogramming Note: If you choose to Make it Your Own, the monogram will be placed on the top sheet (centered on the self fabric hem at the top) and any pillowcases (on the top of the self fabric hem facing out). When the sheet is folded down, the monogram is readable from the end of the bed. Fitted sheet does not receive customization.
