Chair very easy to build a treat after the first chair we bought and returned. Chair is comfortable except for the arm rests. They are too hard we had to make a padded cover for the arm rests.
Since 2020 I've been working from my home office much more than before and was having some back trouble from too much sitting in an inferior chair. I'm already feeling better after only a week with my new chair. This was a very good purchase.
My husband fell injuring his back. Now that he works from home this was needed. He has issues with the lower back and the adjustable lumbar support has great support. He no longer leaves his office holding his lower back.
