Supima Cotton sheet set
Our finest cotton sheets are exceptionally soft and durable, made from responsibly sourced 100% Supima cotton for long lasting comfort. Pillowcases included.
Supima cotton is a rare, superior type of cotton grown in the USA. It represents less than 1% of the cotton grown worldwide. Its extra-long staple fibers are strong and soft with excellent color retention. They resist pilling, breaking and tearing, for incredible resilience and long-lasting quality.
ExactFit™ sheet design allows our sheets to stretch and move with our unique smart beds as they flex, and recover between uses, for a smooth, perfect fit.
With our SmartFit™ design, sheets stay secure all night. A fully elasticized edge, elastic corner seams and anchor bands keep fitted sheets in place.
Logic™ Labels on Sleep Number® bedding make it easy to see which way your bedding fits, right from the start. Simply align the labels at the bottom right corner for easy bed-making.
These supima cotton sheets have a 600 thread count for lightweight softness and breathability.
Our sheets are designed to fit any mattress up to 15" mattress thickness.
Includes:- One oversized flat sheet
- One fitted sheet (Split King and Split California King sets contain two Twin Long fitted sheets)
- Two pillowcases (Twin and Twin Long include one pillowcase)
