Have only had this guy for a week but feels like an absolute dream after working 10+ hour days from an uncomfortable dining room chair. Super plush firm arms are moveable (so it fits around lip of desk) and the wheels are sturdy and haven't yet marked up our floor. May be too soon to tell but already considering buying another for our 'secondary work space' (our basement).
Original purchase had to be returned as the threads were stripped in the arm so it could not be attached properly. Second one went together fine and so far it has been quite comfortable.
I love this chair! I needed an extremely comfortable chair as I go to school full-time from home. This chair allows me to sit comfortably for those 8-10 hour days.
