The Eva Medical Raised Toilet Seat helps to make the bathroom a safer place for people with special needs. It elevates the height of the existing seat by 5 making it easier to sit and to stand. Contains Antimicrobial Product Protection which resists the growth of mold, mildew and bacteria that cause stains and odors. Its continuous cleaning action also makes life easier. While it does not replace the need to clean the seat, the seat will stay cleaner longer between cleanings.
