The stool is beautiful but not at all ergonomic. In order to sit on it, one must have their legs open, right or left from the stool, or be (maybe) two meters tall. The shelf under the seat for tools is plastic, not very hard indeed. It is a matter of time for it to break or puncture. The wheels do not have any "stop," resulting in it never staying stable in one position. Overpriced in my opinion and cannot be used professionally under any circumstances.
