Bought this chair because of its excellent reviews. However the headrest isn't really adjustable. You can only pull it up by a couple inches which is still too low for me. It is pushing against my shoulder. Other than that it is a very comfortable chair.
I got my chair around 170 for reference. I have always heard good things about these chairs and I think they live up to the hype. As for all chairs you have to get up every couple hours or so and readjust. The head rest is ok except it might need more resting positions to make it more comfortable. It's kinda like that pillow you can't fluff up properly. The build is pretty solid and of course it's pretty light.
My husband and my sister LOVE this chair. They both have one and would not be without it. My husband is 5’10” and he finds it very comfortable but his friend who is 6’1” said the head rest hits in an uncomfortable spot.
Loving my new chair ! It is extremely comfortable with great back support. It is also very pretty in Red and Black. Goes great in my new loft office. I would highly recommend this chair. Assembly also went well I didn't hear my husband complain at all!
