Very comfortable chair to do work in. Has helped me get a little more focused at my desk! I really like all the different settings it has as well so that it fits me perfectly.
I received my chair in a box delivered the next day. I am a retired woman not particularly handy but I was able to use the Allen Wrench that came with the parts and to follow the illustrations in the user manual to successfully assemble the chair in 45 minutes. The chair is sturdy seems well built and has all the comfort adjustments you would like. The lumbar support in the back of the chair does not move however. You have to raise or lower the entire back of the chair to find your comfort zone. It feels great. The arms are minimally adjustable up and down and can be screwed on wider than the chair seat to accommodate a very large person. I am 5'6" and slim. The seat is quite ample for me and the narrowest setting on the armrests is wider than my shoulders. However the arms are lower than my desktop and I do not rest my arms on them when I am working. I would recommend this chair. Note that the casters are hard and not suitable for hardwood floors. They are fine on my carpet.
Very comfortable easy to assemble with lots of adjustments to get you in just the right position. I would have given it a 5 star had the lumbar been adjustable. But this chair w the s an awesome value.
