You may have sent me a defective chair. Ihave one in the country which I'm sitting in--and could not get the gear on the one in the city to work. I am returning in September to review it.
It took me a few days to get used to the chair but once I learned all the ergo settings I loved it. Makes working from home during COVID-19 a lot more pleasant. I am use to using a mesh chair at work so this one was perfect. I originally bought the Dexley chair (larger version of the Hyken) and as much as I wanted to like it I just could not make it work for me. I eventually found the Hyken in stock and what a difference those two chairs are. I am 5'9" and 175lbs and the Hyken was just right for me.
