Sturdy and so comfortable
This is a very stable seat. I have one and my mother bought one for her house too as she liked it so much. The little boy tell me that it is much more comfortable on their bottoms than the other adapter seats we have. It is possible to fall off if there is any horseplay or silliness, but that's only happened twice in two years of use. My 5 yr old helps her 2 yr old sister put the seat on and go to the potty by herself, so I'd say this is easy to use.
