3 of us in my office now have this chair and it's fantastic. I love being able to rock back while also giving great support. Also really nice to have a headrest.
This chair is both comfortable and serviceable. The height adjustment is an important feature for me as I must sit high at my desk and it affords me the perfect adjustment for my work. The mesh seat and back allows circulation of air as well as comfort.
It’s a decent enough chair. Maybe a little over priced for the quality. My biggest issue is with the manufacturing quality. Two of the nuts would not receive the bolts. The threads were clogged due to the manufacturing process. Forcing one broke the nut from its mount but I was able to improvise it. I chose to buy a tap so I did not have a problem with the second. If you chose to buy this chair just keep in mind you may have to deal with this sort of thing and either return it or fix it.
