Right now is the best time in the last decade to shop for second hand quality office furniture. The work-from-home drive has left lots of offices empty and there are many companies downsizing their office presence and offloading surplus office gear.
Do you have any recommendations on how to find these deals other than monitoring craigslist and local second-hand stores?
I ordered an Aeron stool from Madison Seating [1] while I was setting up my home office a few months back, and the experience was pretty solid. They have good prices, and the shipping was quick and competent. I'm happy to recommend them.
...not in my experience? Herman Miller apparently sued them back in 2015 for supposedly claiming that refurbs and open-box used stuff was new, but if the complaint was founded then, it certainly isn't any more. I was never in any doubt that I was buying a refurbished chair, and for paying half what a new one would cost, the quality of the chair I got still means that as far as I'm concerned I came out ahead on the deal.
Local version of Ebay for me (marktplaats).
In the Bay Area at least it looks like Facebook Marketplace is the new Craigslist. There have been dozens of these ads on there on any given day in the past few months.
In the Bay Area, what you want is the legendary Aeron Guy, who has a warehouse full of used and repaired Aerons and Aeron parts and will cut you an amazing deal. If you look on craigslist for Aerons, you will likely encounter him.
