I have a Union & Scale ergonomic chair that is very comfortable but it has quality issues and things keep breaking. For perspective I am 140 pounds so it's not a weight issue. U&S are unable to replace a broken part for me for a few months so I bought this chair as a filler for now. Staples delivered it next day and I was happy to receive it. It looks really nice and it was very easy to put together however this is the most uncomfortable chair I've ever sat it in my life. The seat padding is hard as a rock and the built-in lumbar support is not in the right spot. I have back and neck pain after sitting in it for an hour. I would not recommend this chair to anyone. U&S makes some good stuff but this is not one of them. Stay away.
Mesh back is comfortable Material seat is big and comfortable with a lot of support but not too much. I’ve had this chair for a couple weeks So far so good and I got it for under $100
