This is an excellent product. I have two of the smallest one, and one of the largest one. They are fairly sturdy, but I wouldn't want to actually use it for my full weight, as it can come off. I use it when shampooing my hair, just for stability as my knees are not the best. I took the larger one travelling this summer to use in hotel rooms and homes I stayed in. That's why I ordered two of the smaller ones. For convenience of travelling. The larger one was hard to fit in my luggage. I also use a smaller one to hold my bathmat which dries easily on it, and hangs out of the way of others in my home.
