I've had terrible luck with desk chairs and have always had to pad the backs in order to not have constant pain. After trying at least 20 chairs this was the one that fit my small stature and had an adjustable lumbar support for my aching back. I have not yet spent more than an hour at a time yet but I'm hoping longer periods will be equally as comfortable.
I 'upgraded' to this chair from a larger leather executive chair and I am quite pleased. It was easy to put together (if you pay close attention) and is comfortable and sleek looking. I would add that it could be slightly "taller" I am of 'just above-average' height and it is a close fit with the headrest - but overall a good chair and great value.
Comfortable stylish nice chair for the price but don't expect much in the way of adjustments. If you are tall as I am (6'2'') you will not be able to use the headrest. It cannot be adjusted upwards to reach my head. Instead it is at a height where it painfully presses into my upper back. I removed it entirely so I have a chair without a headrest. Probably could have found a comparable chair without headrest for less money but the receipt states to return the chair you must repackage it unassembled the way it came so it can be resold a virtual impossibility because the packaging must be destroyed to extract the parts for assembly. Lesson: Do not buy without first sitting in the chair. Sometimes the convenience of Internet shopping isn't so great.
