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.
Super comfortable and supportive chair. Really nice back support. The only thing I would want more is more of a rocking motion. Other than that the chair is great.
