I've tried many types of office chairs over the years and I never would have thought this would be one of my favorites. It's very comfortable and adjusts seat height arm width/height lumbar support height and head support. All the adjustments are very customizable except for me the head support was too high. I needed to be able to lower it about another .5" (I'm 5' 3") to be just right. I ended up removing it all together and it is fine. It is a great chair in this price point and I would recommend it.
I bought one of these chairs a few years ago and it has held up so well that I bought one for my office. Assembly was even easier than the older model and the chair is terribly comfortable and very well built. The type of support do a wonders for my lower back.
Love this chair. Best comfort offered on the market. I do wish they offered more than black or red as color choices. Or perhaps they could make slip covers? My home office is white and my accent color is a soft pink. The black really does stand out like a sore thumb.
