Probably worth mentioning the Emeco 1006, a similarly iconic chair.
As a lifelong US resident I've seen those no more than a handful of times, always at hipster bars or restaurants.
how old are you?
in my recollection, the old/original ones were around alot kind of everywhere (watch 60s movies with office/interior scenes, etc, though i'm younger than that), gradually fading away, and then the new ones came back on the scene ~10y ago (and yes, now very often at hipster sorts of places)
Anything produced in million-up quantities can be said to be successful, but some are more successful than others!
Well nevermind.
That's the Apple between the chairs
