The cushion on the seat is close to abysmal. It is ashame because other than that every single other feature of the chair is spot on. To add more details to the issue after two hours of use you will notice cushion it is totally flat i think that will be a problem even for a lightweight person. Some of us need to be seat and work 8 hours not recommended for that kind of use.
This was recommended to me by a professional ergonomic expert who regularly fits office workers for ergonomic setups. I asked for a reco that is under $200 and this is the one she pointed out. Setup was relatively easy and it’s very comfortable for my 5’2” stature!
It is not a very comfortable chair and doesn't roll well on the carpet. It was advertised to have wheels that will roll on carpet and that's not correct it doesn't. You should remove that from your advertising.
