I spend a lot of time on my computer editing photographs and this chair is a comfy, good posture reminder. Only negative is that the "freedom component" for the backrest doesn't work for me (pushes against me) as I am a 125 lb. weakling. Hahah. I think if you're a much larger framed and jacked person it may work for you.... Marianne. Sun Feb 12 2023

Have this chair at work (with headrest) so ordered for my office at home now we’re working from home more. It’s very sturdy and comfortable. Good lumbar support which was the primary reason I spent the money - I knew what I was getting for the price. Noticed an immediate difference with my sciatic pain. Assembly is very easy - no tools just attach the base to the seat. The thing I like about this chair is you can lean and the arms lean with you. Also the arms are adjustable.. Sandy. Aurora, IL.
