Classics?

ok, the gray chair is not...
ok, the gray chair is not actually a classic, i just saw it at the local vitra/knoll dealer today and am still shocked.
but the teapot could be called a (postmodern) classic. it's well known even among non-addicts, i know quite some people who proudly own or want one and recognize it as a classic piece of design.

I really can't stand...
I really can't stand Panton's Heart chair or Cone chair.

Really can't abide
I really can't abide Warren Platner's chairs. The tables I like ok, but the chairs are just so....fussy.

Haha. I love Platner's...
Haha. I love Platner's chairs ... I want a pair of high back lounges in white leather with brass frames...
No, that's fussy.

Classic can be a rather subjective notion, don't you think? I think the Nonconformist chair is a classic. It is functional, beautiful, unique, provoking, challenging, and timeless. It is one of my favourite chairs, although I prefer it in fabric (Picture 1).
I actually spent some time trying to come up with a real classic that I dislike, and I couldn't. Not all are beautiful, but most of them have something to say or question, which is interesting. And it is hard to dislike something interesting. I am sure there are many, but my mind is blank at the moment.
However, there is a more modern classic that I dislike: the Aeron chair. It may be very comfortable and ergonomic, but it is not beautiful or interesting in any way whatsoever. (Picture 2).

Catch All. Too messy no matter what you put in it. Just the name makes me cringe--reminds me of Aunt Edith's pocketbook.

Platner
all of it...blech!

Eames fiberglass chairs. ...
Eames fiberglass chairs. While there are rare moments when my eyes enjoy following the curves of the chairs, I generally loathe them.
In agreement with Gustaf...the Aeron chair isn't great to look at. Have you any of you seen/used the new Embody chair (link below)?

Dittos on the Panton Cone and Heart...
The Relaxer Lounge has got to be the most difficult chair to get out of I've ever sat in. And wasn't even comfortable to boot. What a sham, that fellow.
