Once it was assembled, I absolutely love this chair.  Looking thru all the ergonomic chairs, I chose this one because the back support looked good--it is--and because the arms flip up.  I'd read reviews on the desk I purchased that getting the chair under the desk was difficult due to the space for your knees and the arms of the chair.  So I made sure the chair I bought had arms that would flip up and the seat area would fit under the desk.  This does.  It's very comfortable.  I had help assembling it though.  I got stuck on attaching the arms to the chair back.  Awkward.  As it was getting late, decided to try the next day.  The next day my super came up to finish assembling the desk and assembled the chair too.  He ignored the instructions and first attached the arms to the seat.  So much easier.  I'd recommend this chair to just about anyone.
