I have sat in this chair for 16 hours at times and still was comfortable. It fits to the way you sit comfortably. The lumbar support is quite good . It was definitely worth the price.
I did not really care for the lack of support that the mesh seat provides. I'm going to hunt for a cushioned seat instead. In most other respects this is a fine chair - for the right buyer.
This is the most comfortable task chair I’ve ever used. The adjustable lumbar support is great. I would definitely recommend this chair to anyone with back issues.
