This is a wonderful chair. I'm 5'5 135lb so this is from the perspective of someone with these measurements. The back is high enough for me to rest my head which was one of my must-haves. I did read another review where a 6'1" man mentioned it's also high enough for him to rest his head and neck so I think this chair's height is suitable for taller people too. My desk height is 30" and the chair and arms can fit comfortably under this height (and can be adjusted lower or higher if needed). The color is slightly darker than pictured but not a huge difference. Lastly the instructions were excellent. They packaged the hardware in separate compartments labeled with each step so you know exactly what to use when. It's very clear. It took about 1 hour to put together at a leisurely pace while I watched a show. Nothing was too heavy to lift or hold in place. I highly recommend this chair!
This was easy to assemble except for one of the arm sockets on the left side of the chair back. The bolt socket (female part) was angled instead of being perpendicular to the chair back. Other than that it is comfortable and works fine.
