I bought this chair after reading multiple reviews online of office chairs meant for comfort during 8+ hour long work days. Unfortunately the width of the seat is such that the plastic was digging into my hips and was incredibly uncomfortable. I will be returning the chair and buying another more expensive chair instead that offers different sizes to accommodate all body sizes.
The chair is nice and all but it has a problem with the pneumatic cylinder. I got this chair 2.5 years ago and after 9 months the cylinder broke and always lost height over a few minutes. Staples replaced the chair for free and now after almost 2 years the same issue is happening on the new one it loses height slowly until it bottoms out.
