Interesting alternative to the aeron. I have had similar chairs from staples etc... and all of them the seat cushion breaks down to the point where I am sitting on the particle board under the padding after a year or so. Does this IKEA chair do that?

I am not a heavy guy by any stretch of the imagination and these chairs all break down on me so the aeron is something that I am considering largely because of the cushion problem. (also the mesh keeps cool during a long session and the posture elements are nice too)
