I've got my Aeron since ten years and use it daily. It's still like brand new. I don't think I could sit in any knock off and not immediately notice the difference. It took 30 minutes to set up (ten years ago) and I haven't changed anything since then. I put my hands behind my head and the chair slowly leans back: that's the "easy" trick to configure it properly. The one main complain I see about it is the frame hurting people's legs / preventing proper blood flow but I think that's people sitting in Aeron chairs not configured properly. I don't just like the "pellicle mesh" (no sweating) and how great it feels, I also like that it's ten years old and is basically like new despite daily use. As a funny sidenote: during the first covid lockdown I got stuck for three months not at my home and had to use a really crappy chair (as in: an old chair, not meant for office work at all) and within weeks I developed terrible back pain. It was so bad I had someone lend me one of his Aeron.
