The cover is made from a web or laminate of cotton rayon or woollen fibres and p is impregnated with polyvinyl acetate, polyvinyl chloride, butadiene acrylonitrile, polystyrene or acrylic resins or their copolymers. A deodorant such as quaternary ammonium chloride may be added before or after impregnation with synthetic resin. The cover is wrapped around a filler pad which may have an inner cover of semi-water-repellent paper or water-repellent backing or side strips.
