I got my stool today and was delighted to see that even as a novice do it yourself person I could easily follow the directions and put it together myself.  It is SO comfortable and easy to adjust the height.  It won’t fit under my desk in my preferred work height, but it is so easy to lower it and push it right under the desk, totally out of the way!  If I didn’t already have one, I’d order one right now!  I am going to have my husband try it out, we might order one for him as well.  Love it!!
