It's actually quite a comfortable chair for working long hours in because it is both supportive and breathable with just the right amount of give. Also good - super easy to assemble! It only took me a minute to realize that I had put the arm rests on backwards! Other than that it is a very comfortable chair which I can recommend for anyone who needs to sit at a desk for any length of time.
Bought this chair for my husband for Christmas as he spends a lot of hours grading papers and creating lesson plans. He has sciatica back pain and needs a supportive chair. This one had good reviews and it seems to be the support he needs so far and it has a lot of levers for adjustments so I think that will be helpful for him too.
