Unique design features a seat riser made of 2 parts that are hinged together, allowing the ring to be lifted in the same manner as your regular toilet seat. The seat is installed using the existing toilet seat and lid and does not appreciably change the appearance of the toilet. It elevates the seating position by 3″ (7.6 cm) for easy sitting and rising. The hinged benefit makes cleaning easy. Supports up to 350 lbs (159 kg). Hardware kit included.
