Abstract

A bedding system for hospital beds comprises a mattress with releasibly connectable hook fasteners on the mattress end surfaces, a bottom sheet with releasibly connectable loop fasteners on each end, and an optional top sheet with releasibly connectable loop fasteners at the foot end and an optional draw sheet with releasibly connectable loop fasteners on each end. If the mattress is used with the draw sheet, it has releasibly connectable hook fasteners along the edge of each major surface. If the bottom sheet is to be used with the top sheet, the bottom sheet is connected so that the entire mattress head end is covered while only the top half of the mattress bottom end is covered, leaving the lower half of the hook material (on the mattress foot end) exposed and available to accept attachment of the top sheet.

When utilizing conventional hospital sheets, patient movement and/or cranking up the bed contributes to wrinkled sheets and bedsores. The present bottom sheet, which is securely anchored to the head and foot of the mattress automatically returns to its original taut position each time the bed is lowered to a flat position. This aids in reducing wrinkles and potential bedsores and enhances the patient'"'"'s comfort.
