This is a solidly built and very comfortable chair but just note that if you are over 6'3" tall the headrest is not quite adjustable enough to be comfortable. No matter how you adjust it kind of forces your neck forward instead of making a nice place to rest your head. That said for the price buy the chair and leave the headrest off. Its a very good deal.
I've been working for the last 7+ years and I had to replace my old cracking leather desk chair with a full meshed chair with full back and head rest and I was planning on getting a Herman Miller Mirra 2 office chair but this chair is absolutely amazing and worth every penny from Staples. It is absolutely comfortable and super ventilated I am in heaven with this chair and I can sit in this chair for 12 hours with zero issues. I'd get another one if I could!
