I used a traditional potty chair to trian my first child, it flushed it made noise and it was disgusting to dump out every time my daughter went potty. Germs abounded ot at least I felt like they did. So when it came time to train our second child, I bought one of these squishy potty seats for teh regular toilet. The purpose was entirely selfish, I was tired of cleaning out the potty cup! This seat worked great. We did need a stool so that she could get up to the toilet, but that wasn't a problem after the first several tries. Additionally using the potty seat made transitioning to a regular toilet much easier and seemed to reduce the fear of "the big potty" when we had to go in stores or restaurants. Overall I would say the potty choir has its place but the potty seat is a much better choice. And I like that this one is squishy rather than hard for those times your little one is there for a while.
