Query: Good potty/Bad step stool

I bought this potty when my son was 14mts and he loved it and was potty trained by 18mts with the occassional accidents, and night time diaper use. When he was about 2- 2 1/2 I used it as a step stool, and he fell, the step stool slipped and kind of collapsed under his weight. (he was of average weight.) He did not get hurt because I was standing behind him and I caught him. But he was so tramatized that he didn't use the big potty until he was maybe 3- 3 1/2 yrs. I took off the lid because it was just a nusiance.BEWARE this is dangerous as a step stool.My son is now almost 8 yrs old and I am suprised this potty is still on the market.
