This is a nice good looking chair I love the colors. Easy assembly but make sure you leave the side plate screws somewhat loose when you are assembling. Once you have all the screws in then tighten them all up. I saw another review that said this chair did not have a tilt lock. Don't worry it does have a tilt lock. The headrest is perfect too.
I had this chair in my home less than 24 hours after I ordered it! It was not too hard to put together and it has held me in comfort during work almost every day since.
I couldn't sit in the chair for more than a few minutes without it hurting my lower back. The chair seat is not long enough to fully support your legs and the chair puts stress on your lower back. The arms are too high for anyone who is not tall and can not be adjusted - just moved out of the way completely. I gave the chair away to a younger family member. Also it is really hard to connect the chair arms to the seat because you can't see what you're doing well enough to get the screws in.
We bought 2 chairs for our office area. They were a bit annoying to put together but not impossible. We like the comfort and the mobility of the chairs. We are satisfied with this purchase.
This was simple to assemble alone and makes for a comfy chair for a bigger guy like myself (6'1"/295). The tilt is firm but flexible and the height of the chair at the top is plenty high for me. The only downside for me is because of the leather it doesn't breathe and therefore I am returning it. Other than this I would highly recommend this chair.
