CinchFit Sheets

Boat mattresses come in every shape and size — and standard sheets almost never fit. CinchFit sheets are designed to stay on, cinch to fit, and work with the unique dimensions of boat mattresses including settee cushions, quarter berths, and cut-corner mattresses.

Available in 9" and 15" depths across multiple thread counts and fabrics including 400TC cotton, 600TC cotton, flannel, and more.
