The chair is great! I'm a tall man (6'5") and I also weigh more than average. I bought the chair because it said that it supported my weight - I checked the specifications, and it hasn't disappointed. It has a wide seat, which means it's comfortable for me to sit on, and the height of the seat suits my long legs - again it's comfortable to sit on for long periods of time. I don't use the arms much, but I think their inclusion means the seat is wider. The mesh seat and back keeps me cool and it makes the seat light to move around. I spent quite a long time looking for a chair like this. I've not been disappointed and I hope it will give long service.
