What the...?

Found this on craigslist. I went back and forth on it because I certainly don't need another chair. But I decided to go check it out - and glad I did. It is in near perfect condition [just needed a good cleaning] and was only $40! It's not like any chair I have seen before. Still doing research on it. The arms [hands?] are exposed solid wood. It is upholstered in black vinyl and the seating/back is several individual fixed segments. I'm pinpointing it from about mid '60s? Amazingly comfortable.
