Aeron. Get one from Craigslist for $300-$400, sell it for the same amount in 5 years if you get sick of it. I did that with a size C after I lost some weight and found a size B more comfortable. From a TCO standpoint, it’s cheaper than buying an IKEA chair once every 5 years, or an OfficeMax chair...ever. And, during the whole time you own it, it’s a nicer experience than either other option. Steelcase and HumanScale chairs are also similarly acquireable and resealable, but the Aeron is the one people know the name of, plus it’s a bit of a nod to dot-com bust startups in the Bay Area and a nod to chair design in general (read about Eames and the history of Herman Miller if you care). They’re also made in the US if that matters to you: https://www.google.com/amp/s/amp.fastcodesign.com/1669397/an-american-made-miracle-how-an-aeron-chair-gets-built-every-17-seconds https://www.google.com/amp/s/amp.fastcodesign.com/1669397/an...
