This stool by little tikes is rock solid. It now comes in blue with darker blue or pink with darker pink and retails for $18. It is quite a bit more then other children's stools but well worth it. We have 3 throughout the house, kitchen, bathroom and bedroom and they are used more then once a day in every room.
The main reason this product is so great is that it is a classic that was brought back and they started producing again. They didn't change anything about it, and to me older things are constructed better. This is NOT cheap plastic, but super heavy duty. I weigh about 130 myself and have used it as a chair and as a stool with no problem. My son is 40 lbs and uses it all the time.
It is built so it is sturdy and safe and will not topple over. It would take alot to get it to even flilp that would more or less only be when you were stepping on or off, in fact my son had 2 stacked up on top of each other yesterday and was standing on it with no issues, of course, I do not recommend nor do I allow him to do that. The style and color of this is quite pretty and nice that I do not mind at all it being around the house and in with our everyday decor.
