We make specialty bedding for all adjustable mattress types including Split King and Split Flex Top King Sheets like those sold by Sleep Number. Our CinchFit Adjustable Mattress Sheets stay on and do not pop off at the corners. Our Flex Top Sheets with FlexSquare Reinforcement never rip or tear.
[Note: We are re-organizing our website currently. The majority of our adjustable mattress bedding is still located in our Home section and all updates are expect to be completed by 9/22]
