This is a really well designed chair and appears to be very high quality for the price point. I've assembled more than a few chairs and can tell from the molding of the seat area and how the pieces are secured together that a lot of thought went into the design to make it a very sturdy yet easy to assemble chair. The arm attachment to the seat is very clever and the back attachment to the seat is very strong. The adjustable lumbar support is excellent and both of my sons tell me they are enjoying their chairs (we bought 2 - one for full-time work so 12+ hrs / day and another for online class so several hours / day). Too soon to rate durability especially how the mesh attaches to the seat and back however I have no reason to assume it will be anything short of very good. Very happy with this purchase!
