I have been using it for quite sometimes and adding this feedback after 8 months. Chair is worth for the money.. provides good rest on leaning back. Overall a very comfortable chair.
I like most aspects of the chair but the most important part the seat is uncomfortable. The front edge is a bit sharp and digs into your legs. I'll have to add some kind of cushion to deal with it. The chair would be a lot better if the front of the seat had some padding or even just a well rounded edge.
It took a buddy and I less than 30 minutes to assemble this delightful chair. We are paranoid about bed bugs so we traded an older chair in on this one without upholstery. When I sat in it I realized that I could put my feet up on the desk and lean back to relax. This is our second Hyken mesh. We don't use the head rests.
