I have a Herman Miller Aeron chair at the office. This one does not compare but then neither does the price. Yes for the price it's fine I suppose but I doubt I can do an 8-hour day on it day after day. I can feel the metal frame eating into my thighs after a few hours. (In all fairness this is an issue that all mesh chairs share except for Herman Miller chair -- and even then in a ten-hour day....) Also what's up with the arm rests? They look totally backward to me: They extend so far to the front that they bump against the desk and the only way to rest your elbows is to lean all the way forward. I kept checking the assembly instructions in disbelief but no this is the way the chair was designed. Do they use their own product?
The chair is nice and sturdy with good back support. The seat is fine but not cushioned or filled which makes it feel light and a bit different from standard chairs. This was easy to assemble.
The chair is very comfortable and I am pleased with the purchase. I would recommend this chair to others. In fact this chair is the third one we have in the house. Of minor note there were certain bolts which were difficult to attach using the enclosed allen wrench due to the location of the bolts. While most bolts could be attached using the short end of the wrench some had to be attached using the long end. It was harder to grip the wrench for those bolts. Also the metal plates used to attached the arm rests to the base do not lie flush with the base plate even when fully screwed in. Perhaps the pre-drilled screw holes were slightly off. The arm rests are secure nevertheless.
When I sat in the chair in the showroom it felt perfect. Setting up one at home was not difficult but you do have to pay attention. I put the seat in backwards! My fault it is labeled for front and back I just overlooked them. It is very adjustable so give your self time to try out several combinations until you get the right one. Once I got the chair in front of my work at home desk it took a few adjustments over about two days to get everything just perfect. But perfect it is. Recommend this chair very highly.
