This chair is comfortable working all day. It has more ways to adjust than just height. My desk is too high but i can still sit with my feet on the floor because the arms adjust so that my arms/wrists are the right position for computer work. Rolls well too. I had it put together at the store.
I purchased my chair approximately 2 1/2 years ago and I love it. I bought it for work and it is the only chair I have that does not hurt my body. I have psoriatic arthritis and it is painful for me to sit at a desk and work. However this chair fits by body & supports my back and I am able to work comfortably all day. I recently started a new job and I took the chair to my new job. I also keep the link to the chair handy so that I can replace it if ever needed. Last year I bought a similar cheaper chair to have at home and I cannot use it for any length of time because of the pain. This will always be my go-to chair.
Chair quality is good. This chair raise higher than others which is very helpful. Control are easy to use and assemble is fairly simple. Sale price makes it a good bargain!
