The single Siba Satin 2 Way Fitted Base Sheet lets you reposition yourself comfortably in bed without slipping. This fully fitted base sheet is designed for comfort, with a central satin sliding panel allowing you to turn from side to side in bed. The 2 way sheet removes the risk of sliding forward whether sitting or lying flat, and a cotton edge prevents further slipping. A drawstring mechanism along each of the long edges lets you make fine adjustments for each mattress, and vents in each bottom corner to allow air hoses to be attached to dynamic mattresses. The satin weave has been designed for easy movement as well as locking. This sheet is also suitable for machine washing and low-temperature tumble drying.
