After the last 3 days of WFH, I'm seriously considering a good chair for home as well (though I like how the plain wooden one I have looks, with my plain wooden desk). I've owned an Aeron for years and never regretted it, but I keep it at the office (it's at its 3rd job with me) and because they're on wheels a second Aeron would chew up my wooden floor.

Ideas for a plain or funky, ergonomically great, non-wheeled chair gladly accepted. Anything up to Aeron price is fine with me.
