Buy this if love methly isocyanate. It is toxic and they used excess when making the foam. I am letting it air out in the garage for the next month in hope that the toxic chemical smell goes away.
I'd say this is a great chair for the price with my only two qualms being that even with the tilt lock in place it reclines too far back and the headrest could've been placed further forward so that I wont need to lie back for it to support my head. Assembly was also straightforward so I went from unboxing to sitting in the chair in about 15-20 minutes. N.B. I am 230lbs and 6'-2"
The chair is very comfy for working in for 6+ hours. A lot of lower back support is provided. It also has adjustable armrests that go up and down; the only caveat is that I cannot turn them inward and outward. Nonetheless I would recommend this chair.
