I have had this chair for less than four months and the seat is already becoming unthreaded. Also the warranty only lasts two weeks. I would not recommend purchasing this chair to anyone because of how fast it wears. (I only weigh 160 lbs).
I am quite happy with this chair. Looks good. Very comfortable. The instructions were very clear. I particularly liked that they had the screws in packets that were numbered to match the instruction step. No hunting for the right screw! It took me maybe 30 minutes to assemble.
I was looking for a chair that would fit a tall person and give the proper back support this chair accomplished both. The mesh is perfect if you're looking to stay cool and also cleaner then a foam seat and better for circulation.
