Query: Simple and sturdy

We started with the seats that mount to the toilet. They were ok but this is so much more sturdy. The molded shape lets me feel like my 2 year old daughter is stable on the seat. They also pop out easily, with a pressure fit and easily adjustable dial. I'm a big fan and if you have any hesitation, don't. This is a simple, no-fuss quality product.
