I had lower back surgery in January lumbar support feels good. Having trouble with my back when sitting too long. This chair was ok at the store when I sat on it for thirty minutes. In my opinion not good for me with my back. Looking for another chair.
It is a good quality chair and it has good ergonomics. It was easy to assemble. The headrest adjustments are kind of poor and may not work for many taller than 5'10''.
Chair is quite comfortable especially with the head rest. There seems to be sufficient chair adjustments for my needs. The product I received looks more black than the gray I ordered. The parts to assemble were relatively straightforward aided by a thorough assembly manual and numbered parts for ease of assembly. Would recommend highly. Nice chair at a very competitive price.
