This is a dangerous potty chair! I wish I could return it to the store but threw away the box before I found out just how terrible. The chair is not comfortable for the child, after sitting on it for a few minutes they end up with a red circle around their bum; my child complained about it. Additionally the potty cup, since it's removable, can also shift which can cause the child's skin to get pinched.
This potty has 3 functions, a potty seat, the chair piece comes off and can be attached to a regular toilet, the bottom piece can be turned over and used a step stool. The step is very dangerous, it slips and slides across tile! There are only 4 very small rubber tabls on the corners, not enough to securely hold it. Well, it's not enough as it slide across the bathroom floor as my daughter tried to use it as a step stool.
Also, it's very tippy, my child flipped over backwards when she sat on it once, it's just a bad design. I expected better from the maker, their baby stuff is typically very good. Avod this one at all costs.
