Abstract: A small and irregular shaped mattress sheet cover system for covering a bunk mattress. The system includes a flexible tubular cover that includes a body slightly smaller in width than a small or irregular shaped bunk mattress and with a closed end and an open end. The body fits longitudinally and snuggly around the bunk mattress. In one embodiment, the bunk mattress is triangular and fits inside pointed berth area on a boat. The cover may include optional end flap and optional pull straps. The method includes the steps of rolling the body into a flat ring configuration, aligning the ring with the end of the mattress, and then longitudinally pull and unrolling the ring over the mattress. The mattress may be folded or compressed inward. The pull straps are used to pull the body over the mattress. The mattress is then allowed to expand and conform to the body.
