I accidently bought this potty chair instead of the Potette Plus. Please do not make the same mistake. This one does not fold out to fit on a toilet seat which is why I bought it. It folds out to sit on the ground and use with liners. There is no reason to buy this seat when you can buy the plus model and have both options. I wish that I would have read some of the other reviews before I bought it. It might just go in my garbage.
