The structure is quite simple. Follow the arguments is required, manual dexterity is not needed one. By this I mean something else. The stability is sufficient but not unlimited. The Bath depends quite deep in the tub. This requires a smooth drain in the seat. If you immerse yourself fall for he survived the unlikely. But higher stability is also linked mostly heavier and then the seat would no longer be so easy to handle. A reasonable (or even several) handhold on the wall belongs to a disabled person necessarily so.
Upside down you can use the seat as entry aid. For a body weight above 70 kg body weight but I have doubts. For the seat happens to be not created. I would recommend a real entrance aid this.
Five stars for the seat in relation to the price. One star deduction because of overly optimistic description. Nevertheless, recommended.
