Comments about basyx by HON basyx™ by HON Fabric Mid-Back Managers Chair, Charcoal:
I was looking for a nice chair for my personal home computer. I did not want to spend alot and thought the lower priced chairs would be too cheap and uncomfortable if I were on my computer for more than a few hours. This chair was very easy to assemble, only took me 25-30 minutes following the directions. It looks nice. [...]I use it just for personal home computer chair. Maybe a little more padding in the seat and have the seat extend out under legs a little more for comfort. Good chair for the price.
