I have this stool for a year now and I'm very happy with it. It's very well constructed, the fabric-covered seat is extremely comfortable and encourages one to sit in a more upright, comfortable posture. The mechanisms all work well and it folds into an easily transportable unit. It comes almost fully assembled, you just need to fix the foot rests. That's a simple job, and they even include a spanner. My one disappointment is that the rubber pads on the foot rest are starting to wear. I do use this about three or four times a week, but I still think they should be harder wearing than that. One other tip, is that you should glue the rubbers onto the base. They have slipped off on me a few times and I was lucky to be able to retrieve them. All in all, I highly recommend this.
