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.

Do you have a King size FlexTop or Split bed? Our FlexTop King splits only at the head, which allows the head of the bed to be raised on each side independently. Our Split King splits down the entire bed, which enables each side of the bed to raise and lower your head or feet simultaneously. View our mattress size chart to compare bed sizes.

Fabric
600 thread count, made from 100% Supima extra-long staple cotton grown in the USA.
Made in China.
Washing
Do not pour detergent directly on sheets and avoid chlorine bleach or detergents with added bleach or whiteners.
Do not use fabric softener, overload washing machine, or wash with non-bedding items. Doing so increases friction which can break down fabrics or cause pilling.
Drying
Remove from dryer while slightly damp to prevent wrinkles. Do not use dryer sheets as they may weaken and break down the yarns.
Storage
Store sheets in a cool, dry, well-ventilated area. Do not store in plastic containers as this may cause fabric to discolor.
Please Note
Certain hair and skincare products may discolor sheets and pillowcases or cause pilling.
MADE IN GREEN by OEKO-TEX® awarded for sustainably produced textiles made in environmentally friendly facilities and tested for harmful substances.
