I had no complaints about how sturdy the potty was, or how well it worked. My complaint is that about a week after she started using it, my daughter got a rash in a circular ring on her bottom that matched the potty. We stopped using it and the rash cleared up. We tried it again and she immediately got the rash back.In the end my daughter was potty trained without a potty seat on an adult toliet (it can be done) and we only used the step stool part of the potty.
