Collection: Split Top King Sheets

Make your adjustable bed more comfortable with CinchFit American-made sheets for Split Top King beds. Designed for a mattress that’s split at the head and joined at the foot, CinchFit combines flexible jersey knit, a reinforcement patch at the split, and an adjustable fit to help your fitted sheet stay secure as your bed moves.

Your adjustable bed moves. Your sheets should move with it. Flexible jersey knit accommodates movement, while the reinforcement patch helps protect the stress-prone split area. CinchFit’s adjustable cord-elastic fit lets you tighten the fitted sheet around your mattress for a snug, stay-on feel, with less slipping, bunching, and readjusting. Its universal fit works with all split lengths, taking the guesswork out of matching your Split Top King mattress.
