I saw the seat at Rehacare 2014 and then ordered it for our now 8-year-old son, since all the other seats were now too small for him. The seat is stable, comfortable and warm to sit on, reducing the toilet opening (our son usually has Afraid of falling into the toilet as he cannot sit freely). Slim adults can also use the seat. If our son holds on to the handles on the side, he can stand up or sit down by himself after putting his pants on. The seat is easy to clean, but after a while, a yellow color from urine remains on the inner edge. But you can not see that from above, so I don’t think it’s a bad thing. Despite the steep price (plus postage), I can recommend the seat.
Note: Potty Seat should be cleaned after every use, with a disinfectant wipe.
