I've been using this chair for four days.  The seat is not comfortable.  It is not well-padded and it's very short from back to front.  I am a 5'4" tall woman and the front of the chair reaches just to my mid-thighs when I am seated as far back as I can go.  I think it would be very uncomfortable/inadequate for a taller person.  The padding feels like it is non-existent and I feel like I am sitting on a wooden board. The rollers work well and I like the easily adjustable arm rests.  Edited to add:  It's been a few months since I left this review and the chair has only gotten worse.  The lack of adequate padding has become a big issue and I've added my own seat cushion.  I'm shopping around for a new chair already.  Do yourself a favor and spend your money on a better chair.
