The chair is comfortable for hours of computer work. It is very well suited for people who prefer a short seat. The side handles are great to keep you from falling off the sides. (Very important.) However you must get used to the extremely fast sliding wheels. Do not sit at the edge of the chair because the chair will go one way and you will hit the floor. It is exactly the right chair for me after paying twice as much for another which was not as comfortable. The lumbar back support is really great!
I am 5'1" tall with a petite build and lower back problems. This chair is short front to back has lumbar support in the right place for me and is cushy(is that a word? Lol) but not too much. I really like this chair alot!
