Silky-soft blend made with responsibly sourced botanical lyocell fibers offers light, airy, conforming comfort throughout the night.
Lyocell fibers are naturally soft-to-the touch, gentle on skin and move moisture, giving our sheets and pillowcases added breathability and long-lasting comfort.
Derived from responsibly managed forests because we care about the planet and you.
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.
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

Do you have a King size FlexTop or Split bed? Our FlexTopKing 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.
