All of our Boat Bedding Products are made across the USA by skilled seamstresses. We are the original creators of these Universal V Berth Sizes! Only our Boat Sheet Sets have our CinchFit fitted sheet design that cinches to conform to odd shaped mattresses and fit snug. With two Universal V Berth Shaped Sheet Sizes and Rectangular Sheets in both 9 Inch Depth & 15 Inch Depth Options we have bedding options for almost all boat mattresses without having to pay for custom boat bedding.
