The last company I worked for, we had these funny looking chairs.
I didn’t think they were particularly comfortable or anything, just different.
Today I realize they are the Aeron Chair by Herman Miller

That’s an $800 chair.
I am not sure why the people at my company at the time thought it necessary to spend $800 on a chair, but I could think of a bazillion other uses for that money.
