I have an Ergohuman chair in the mesh. My co-workers are always asking to sit in my chair for a couple of minutes because it is such a hit right now. We have these crappy chairs that we are provided but for anything decent we have to pay ourselves, it sucks. But, the Ergohuman has been very good so far. They are actually quite a bit less than $600 right now. http://www.beyondtheofficedoor.com/EroHumanMesh.php
