My wife picked this up because after six months of pretty extensive use her old desk chair had had enough. She likes the fact that pretty much everything is adjustable and the lumbar support (which is also adjustable) actually works. Her only concern is that the angle of the seat cushion makes her feel a bit like she's going to fall forward onto her desk and she plans to add an additional cushion to help alleviate that sensation. Otherwise it's a winner.
I like the chair it feels solid and the padding is firm. The only minor annoyance is the arm rests have this harsh line dug into them (90 degree angle indent) that feels out of place on the soft rounded feel. It is almost as if it wasn't supposed to be there and the arms were to be rounded and seamless but they didn't rework the mold to seal them up completely.
