Depends what you like. As people have said, you want to go sit in a bunch of chairs for a while.
I love my aeron. Comfortable, adjustable, but also durable. I used to go through regular office chairs every 2-3 years (yeah, HR didn’t love that). I’ve been sitting 4-12 hours a day in my aeron for 18 years now, and it’s still doing fine. Had to replace the casters on my spouse’s one this spring. Took a good 20 minutes.
(Of course, it also helps that we got ours on some insane dotcom-overstock deal back then.)
