This chair provides the mesh ventilated seat I need for extended time on the computer. The not so good news is that the assembly was very arduous. While the screw/ screw holes alignment was mostly good the mount for the head rest was off a significant amount. The problem was corrected by elongating the mounting holes. The mounting screws were a very tight fit! I hope they were planned that way so that they would not come loose!
Just purchased the Hyken Ergonomic Mesh chair and what a difference it has made in my life! I have sciatic pain many days but with this chair I have no pain! I am amazed! The chair sits straight comfortably and then can rock back giving your back a nice stretch. The neck support is a welcome plus! Thanks to the engineers that designed this chair. I look forward to the comfort for many years.
I bought this online because it (a) had most of the features I want in a chair and (2) had a lot of good reviews. Despite it working on paper my body doesn't agree with this thing for whatever reason. I just cannot get comfortable in it. I've tried it periodically over and over hoping that would change to no avail. Had I sat in it in a store for a few minutes I likely would've realized it wasn't going to work for me and wouldn't have bought it. Bummer.
I found this to be the most comfortable adjustable ergonomically designed chair on the market. It came in a brilliantly designed box with well organized parts and assembly instructions. It took me a little over an hour to fully assemble it. I bought it on a discount but even at full list price it is worth considering.
