It was love at first sight the first time I saw this chair. It may have been in House Beautiful or on Decor8. I am not sure. But I am smitten. The bad news is that this is a very rare – and therefore very expensive – chair. The good news is that it's not one of the pantheon of iconic mid-century pieces. So perhaps some unsuspecting homeowner may put one out in a yard sale one day. A girl can dream!
It turns out the man who designed this exquisitely bendy, twisty scroll arm bentwood chair is George Mulhauser (American; 1922-2002), who also designed a much more well-known Plycraft lounge chair. Designed in 1965 for Plycraft, the scroll arm chair is hard to come by, but I have my eyes peeled. it is like a more ornate, playful version of Cherner's equally jaw-dropping arm chair. Think Cherner chair through the rabbit hole.

Oh, my! I can't take my eyes of it.
Stunning
Now THAT is mid-century design I can appreciate. Finally, something I can hunt down that I'm not going to be absolutely sick of seeing in every magazine and blog post and therefore resent given enough time. I vote for more of this!
Street Snobbery
There's something very Tim Burton / Dr. Seuss about it. I like it a lot, but it certainly isn't subtle.
Ooohh...I doth love it's spirally goodness. And I agree with @Shane101, I do not like mid-century anything, but now I guess I do!
@Dempsern, I think it's far more subtle than many of the chunky-clunky icons of MCM. It's airy, sculptural, and full of movement. It reminds me of the Rythmic gymnastics done with ribbon.

Fun! I'd love to have me one -- AS IF!
This might actually be the first thing labeled midcentury that I like, not to mention love. It has so much personality!
It's nice. A bit much, though.
It's gorgeous. I suppose it's churlish to point out that the arms look as if they would be rather uncomfortable and awkward to deal with -- perhaps one buys these mainly as sculpture, anyway.
So cool.
