panton chair original?  

Panton Chair History
1967: Vitra and Herman Miller
Painted fiberglass
1968-1971: Vitra and Herman Miller
Painted polyurethane (heavy)
1971-1975: Herman Miller
1971-1979: Vitra
Dyed polystyrene (with molded ribs under the seat to keep it from cracking)
1983-1990: Horn GmbH
1990-Present: Vitra
Painted polyurethane (the Vitra models have Panton's signature molded into the base, so they can be differentiated from the original PU production; I don't know whether the Horn models also have the signature)
1999-Present: Vitra
Dyed polypropylene
If your chairs are 25+ years old, they're authentic; knockoffs have only recently been cost-effective to make.
If your chairs are painted, have no ribs under the seat, and have no signature, they're either 40-year-old polyurethane or (if Horn chairs don't have the signature) 21- to 28-year-old polyurethane.

many thanks!!!
many thanks!!!

Vintage Panton ID please
Great production history, thanks. Did you ever see an S chair with the raised marks: XX underneath the seat near the round injection nipple, ribs not only at the base but also extra Ones, longer, that are parallel to the edges of both sides at the lower back and follow through under the seat? (Hardly visable from the back view). Wondering what year this one is & where it was made. I've had it 20 years & bought if from someone in US who thought they had it 20 years.
Thank You!
Panton lover

I have one too
Dark brown dyed, heavy plastic, ribs (but not the same ribs as Herman Miller production), unmarked, undated. Looks like it has some age to it.
Been trying to figure this one out.

Its . . .
It's really difficult. Ive got a Panton Chair sat here. Very heavy at almost 6/7kgs (trying to weigh it on bathroom scales!?!). Painted gloss white. Total height 32". Seat height 17" Couple of pics below showing base of chair & a small section where paint has been chipped.

Looks like fiberglass
Any markings?

No markings . . .
Can't see any markings on it.
Ive measured the chair and the sizes match those given on the Vitra website.
Like I said, tried to weigh the chair on bathroom scales but it was proving to be difficult, but it is heavy.
I bought it approx 1 year ago and have been using it as an office chair. But it was not until I recently purchased two cheap "Panton" chairs made from ABS plastic that In noticed a significant difference in quality.

Weighing is difficult?
Stand on scale while holding chair. Stand on scale without chair. Subtract.

It is . . .
More than likely to be from here . . .

But who would the manufacturer be?

In that case
It's probably manufactured in China.

Then
it was manufactured by Vitra. The company used these labels until 1978, I think.

panton
thanx for te fast response
Does anyone know how to renovate these chairs. Because there is little information on. or does the chair lose all its value when doing? As an architect student, I will certainly not sell them, but I want to know how much this is worth.
I have added pictures after the cleaning. ik looks like onley the primer stayed on. they are realy matt. I also pictures of what's left over from the "Herman miller collection" sticker

True color
The true color of the chairs is underneath the paint. I would suggest stripping the paint and refinishing.
