Another Delusional Nut Bag  

I'm sorry, I must call foul.
How can anyone be reasonably expected to resist a subject heading like that?
The chair is obviously a very early prototype and easily worth twice the asking price. If you took the time to peruse the seller's other listings, you'd see that he/she has unearthed a trove of mid-century masterpieces and is well qualified as an expert in this area.
How dare you, loft? Really?

It's been reskinned.
So I believe it's worth even more.

Worth every penny
I'd say he is bang on the money - an absolute steal.
I don;t want anybody pushing up the price on me when I go in on the bidding. Ok people?
- A.S.

Maybe
Maybe there's funny surprises in the cushions?

Wha???...
Do I detect a hint of sarcasm in these replies? Does this mean that it could actually be a Herman Miller REPRODUCTION?

Does this happen often?
This has to be the worst...right? The first post implies that this happens frequently. Love the sarcasm, but really, has someone ever told one this big before? I am torn, trying to decide to report him. Sure, you could say anyone one dumb enough should be parted with their money, but geez...

Sarcasm? Moi?
Dano, you are completely right. A reasonable offer, which the seller is open to, would be to allow him/her the opportunity to withdraw the auction or edit the description without penalty.
I'm guessing the listing will disappear.

Lolzers, that's quality entertainment...
The singular photo is also a nice touch.

Truly
I'm sold.

Wait a sec.
"This is NOT a H. Miller reproduction or Plycraft knock off"
Both those things are true!
It's not a Herman Miller reproduction. That's quite obvious.
It's also not a Plycraft knock-off! It's a GENUINE Plycraft. So he's correct there, too.
I am going to have to think about skinning some chairs, I see. It seems like a really good move financially.

Just to keep things interesting
I sent the seller a link to this thread. With any luck, he'll drop in to educate us on Eames Lounge Chair authentication.

All this talk about...
All this talk about reskinned nut bags is making me a bit nervous.

Nut
bags are not that uncommon in the US. Real nut bags, I mean, not the delusional ones. Certainly worth more that that piece of crap chair that is listed on ebay.

Seller response
I also emailed the seller, explaining that this is Plycraft, not Herman Miller, and asked if he'd change the listing now that I'd disabused him. His response: "Miller design has a 5 prong support and a different arm rest. Thanks for the advice."
Weird. He seems to be acknowledging that he knows that his chair isn't Herman Miller. But his listing still states Herman Miller...for sale for an insane $10,000.
