Abstract: A protective covering assembly for removable placement over a bed restraining side rail, made of spaced members, has lengths of preformed pipe insulation, cut and fitted about the spaced members, to provide surrounding padding for them. Thereafter, sheets of heavy duty plastic upholstery are cut, sewn, and fitted up, across, down, and under, the padded bed restraining side rail, as an envelope, to provide a surrounding, restraining, easily cleaned, protective covering. Then to provide for the removal of the covering assembly, an openable fastening assembly is secured to the plastic upholstery, which when opened, serves to clear the envelope from the padded space members of the restraining side rails, during their relative movement.
