This chair is just my size. As I am only 4' 11" tall I sometimes have a problem with the fit of any chair. This one does the job for me. The lumbar is extremely important to me and this one is in the right place for my stature (or lack there of). It was also fairly easy to assemble. Glad I purchased it.
This chair actually makes my back feel better than before I sat in it. My stepmother came to visit and she asked me to go buy her one too. Can't say enough about this chair
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.
