Abstract
Abstract A drawsheet of substantially frictionless material for use on a bed, to enable the user to easily slide thereon. The drawsheet may be applied over a sheet of normal sheeting material or attached thereto, in the area of the bed upon which the main portion of the user''s body is normally located. This enables the user to easily change position by providing a substantially frictionless surface upon which even an incapacitated person may slide.
