advice on buying an eames 670?  

i'm no expert
and none have chimed in yet.
A few thoughts about the base...
I've not seen one in solid crome. Also, the under side view shows
a base that has hollows. The 670 has a solid v and it is black and has
metal glides.
Could be a base from another chair?
Or did variations exist?
I'm looking through the Merrell lounge book now.
I've not seen that style label but i could be very wrong about that.
Mine is paper.
It is a handsome chair.
Another disappointment is it is without a footstool?
A very important element to the comfort of the 670, in my opinion...
The book does mention original vs knockoffs briefly, but i'm a bit
surprised it does not go into identifying a key labeling system to help out.
(obviously changed over the years)
The aluminum group chair has that style base but i think it is a 4star.

The price is good
The price is good and all things look right - the base is a Vitra base. My guess is that this may have been a special order, or someone polished the base aftermarket. Either way, it looks original. The clips inside the shells look good, the armrests are welted properly, and the labelling appears correct. The only thing thats a little odd is the black square under the spider mount on the base. But that could be something the owner is putting there to prevent scratching?
If this were in my neck of the woods I'd jump on it!

Looks like a vitra base thats been polished. Only oddity is the black plate between the seat and base; there appears to be additional screws so maybe it's a repair.

thank you all,
the chair does look good, I especially like the leather, though the color will make it impossible to find a matching ottoman.
the plate is a little strange indeed, but as I look longer at the highres photo it might even be plastic and not supporting the panel which looks undamaged from the top.
I did a little windowshopping and saw that Vitra sells them with exactly that chrome-base and white leather. I also saw prices at a local MCM-dealer and so I'll give the seller a call tomorrow and see where it goes!

being a colloctor of original furniture,
i love what vitra did with the 670 lounge chair and how they gave it a nice update with the shiny base, and white leather, if you want it,
that base and chair listed would be so easy to do that, and save a bundle on a great chair.

The base is correct for a...
The base is correct for a european version. These were made with herman miller all the way back to their origin by hille in england and ICF in italy. I believe vitra was a latecomer to the 670 game. I have an ICF one that I am going to be selling in the near future. It is like the one you are looking at but without the plate on the base. Mine is new enough that it does not say herman miller on the label like the earlier ones did. Vitra sued ICF at one point for the herman miller name and won. I would agree that you might be frustrated with an unusual colored one without an ottoman. You will probably be wishing you had one rather soon after getting the chair. But if the price is right........

I'm not
I'm not 100% sold on the idea of the fully polished base. It seems overly flashy and perhaps a little feminine for my taste. But then again, I also think the white leather reads as very feminine.
I think Vitra got rights to the chair fairly early on - as quickly as 1958 altho I can no longer find the detailed timeline on the Vitra webpage. I would just ask the seller what that black square is - metal plate or plastic. New cushions can be had via Graham Mancha, and you can eventually find an ottoman. Not everything will match properly, but that becomes part of the story of the chair.

you know,
I find the idea of having a story behind every piece of furniture very appealing! Price and wood speak for this chair, the chrome is a change from the usual and suits my aluminium group-pieces. The search for an ottoman will be a story to tell, but then again I'm not into this for the fastest way out anyway 🙂
failed to reach the man on the phone, sent another mail. waiting anxiously; want to know, want to have!
I'll let you know how the story will end.

If you refer to a thread titled "eames/vitra debate" there is a little more info. I remember finding a reference that the suit was approx. early '90s. ICF was making them all along with herman miller and vitra was making other herman miller items. It seems at some point I cant determine, vitra started producing the 670 and then went after ICF for the name. I cant find the reference now but I do remember it being something like 15-20 years ago. This is a close as my research took me to establishing a european timeline for the 670.
