I have been using this chair for about a week and a half now and I have to say that I really enjoy how comfortable it is.  The feature of the adjustable arms comes in handy when I pull up to my PC desk and want to push in close.

I will say that when it arrived one of the arm rests had been packed a bit to tight and had a bit of a void in the foam.  After about a week it almost came back to normal but you can still feel a subtle void.

Lastly, assembly was not as easy as I expected as the arms of the chair are what connect the seat to the back and I found it a bit difficult to line up the holes properly.  Took me about an hour to assemble and probably should have taken about 15 minutes.
