Eames Lounge Chair  

It looks authentic.
Perhaps it was manufactured by Vitra.

Looks right to me, too.
And I think Mark's probably right about Vitra. That is the Euro base. The quality of the casting and finish of the seat pan support in your closeup photo is a good clue and I remember seeing a vaguely similar orange Vitra decal on a 670 years ago. The arm pads look to be the longer, squarer, earlier ones, which I prefer.
Nice grain on the veneers and the cushions are squashed just right. It's gonna be difficult to find an ottoman that's a good match, though. Good Luck!

Those black
metal parts look to be powder-coated. If so, I wonder when that started. How far back does powder-coating technique go ?
A nice upgrade, in any event. Charles would approve . . .

nice one!
it looks like a very nice, authentic vitra chair to me. the decal is legit, i've seen it before and everything else looks just right as well.
interesting point about the powder-coating! the chair seems to have down-filled cushions, so it should be an early vitra production. when was the technology introduced? and when exactly did vitra switch from down to foam?

some info here

Commercial use of powder coating started in the late 60s
or early 70s.

yup, late '60s is what...
yup, late '60s is what wikipedia says as well. so vitra was an early adopter 🙂 the base of my chair is still lacquered and has a more matt finish than this one.
anyway, obviously vitra usually changed things for good with the eames designs...

Thank you
Thank you so much for your answers, appreciate it.
Maybe this is a stupid question but have to ask; why is it a Herman Miller decal underneath if it's produced by Vitra?

Vitra had licensed the Eames
"Vitra had licensed the Eames products originally from Herman Miller for sale in Europe and the Middle East between 1957 and 1984, but in 1984 the rights were transferred to Vitra who have been offering the products directly to their customers."

So, from what I understand, even though Vitra made the chair between 1957 and 1984 (with some modifications developed by the eames themselves), they were acting as a kind of distributor for Herman Miller. So the decal?
Does anyone have more information on the different armrest? does Herman Miller had also a different kind of armrest? I've never heard of that...From what I see on these photos, the back shell is slightly pushed away on the left (the space between the seat shell and the back shell is slightly bigger than on the Herman Miller version ( probably because the armrest is longer?). I like it!

Two different arm pads on HM, too.
I hadn't been aware of both until Alfie sold me a complete set of vintage cushions with the squarer arm pads. I don't know when they were discontinued, but the set I have are for the clip-style hardware. The arm pads do not determine the spacing between the seat and back, as the two styles are interchangeable.
I do find the squarer pads - perhaps I should say "more trapezoidally-shaped pads" - to look better on the chair. They seem, maybe, a more deliberate element than the less defined, rounded arms.

Thank you! Always good to...
Thank you! Always good to get some more knowledge about these items.
