I have a Herman Miller Aeron at work and wanted something like it at home (at a lower price point). This chair fits that bill well. My only small omplaint is that the lumbar support does not move enough to get to my perfect spot but it is still very comfortable.
This chair is perfect for my virus-enforced work at home. I can adjust it to fit. And after 9 hours of working I have no backaches. I didn't thing I needed the headrest but it does come in handy.
