So I am super picky about my chairs.  I LOVE that this has three controls on the side as well as arms that can be raised.  The chair is sturdy but not heavy!  They are extremely easy to put together (and they even come with extra screws, washers, etc just in case).  Initially, I had complaints from some employees but once they learned to make adjustments with the levers every one of them is now happy!  I made sure to spray them with fabric protector just in case of any spills.  This chair is a total win!  (And the price is even better!)
