Just got this chair yesterday. This is a GREAT value! Just threw out chair that I've had for a little longer than five years...no arms, nominal settings. At that time, I paid a little more than a hundred dollars for that chair and it kept doing things like it was possessed (sinking downward whle some is NOT sitting on it, tilting forward and nothing to put it back in place...all kinds of things), and it only came with four wheels. This Flux II comes with five sturdy wheels, making tipping over& lessening the chance of tipping. This is so comfortable, but I can tell that there is a tendency for the padding to become flat in the future (my work chair felt the same way before it became like sitting on a metal frame. The fabric on this chair is almost like microfiber and very comfortable (not scratchy or itchy), but it seems rather thin, hope it holds up. The metal foundation is solid, and the control is a dual usage lever, seems okay, not great, just okay.The only drawback is that this chairis rather heavy and bulky; but how often do you carry a chair with wheels? and the bulky part...just make extra room for it. Of course, we are talking about $47.99 here...you can't get better for this price!
