Scott, when I first posted on this thread I was looking for the link for that chair and couldn't it (the review that you did), do you still have the link for it please?
Liz, that really is a nifty stool!!
Steffan, I haven't gotten the knack of adjusting it with one hand- I turn around and re-hook it. It is very easy & quick- I got it the first go. Just make sure it's hooked in well tho. The chair pad itself is too heavy for me to attempt one handed- like the frame, the chair pad itself is solid and heavy, which is a good thing.
In my opinion, the solid nature, height flexibility, storage convenience of this chair, far out weighs the inconvenience of having to get my butt off and turn around and adjust the chair. Okay, I know I'm a lightweight, but others have said it's solid enough to hold people that have got some weight on them- I can perform near gymnastics on this thing and it doesn't budge for me, so I'm secure that I don't fall a over t on top of the tube.
I did a measure of my chair and here it is:
Total height of complete frame: 3 feet.
Adjustable increments: lowest level to highest level is 2 feet.
Seat width: 34cm
Seat depth: 25cm
Seat depth in total from the frame/back rest: 32cm
The adjustable working level is huge. Great for a dob at Zenith. I'm only 5 5" and have not needed to use the highest level yet on my 10" dob (come close but

).
