Brno Chair Stickers  

Your chairs were not manufactured by Knoll.

Why?

Knoll Bruno chairs use an "alllen" head screw to attach the optional arm cover....and the corner on the rear arm ending pictured above is not Knoll. It should be a bit more squared off (less rounded).
But then, I'm usually ______.

Thanks for your effort,
I´m still not convinced. I have also one original Brno Chair with pillips screws. I think the older chairs have phillips or slotted screws.
And if you compare the corners, they are nearly the same. Whatch the pictures. Even the corner of the unknown chair is less rounded. Left original, right unknown.

Consider measuring your chairs ( w x d x h) and weighing them as well. Then contact the experts at Knoll (hopefully with some better photo's), and report back.

I´m from Germany. Have these chairs also been maufactured in Europe? The measures and the
weight are the same as the younger original Brno.

I have a 6 pack of matching Bruno's that have the typical "Art Metal Company , New York" on the sticker. Some retain their original "Knoll 320 Park Ave" sticker's. The armrest attachment screws on all aren't flathead, nor phillips...but a tiny hex screw (allen?). Your answer will come. Call or email Knoll, and let us know your findings.

ps mine were purchased in mid 1960's for my fathers office.
sidenote. In your above picture comparing the Knoll chair with the mystery chair...I can't help but notice that the welting is much smoother (better workmanship) on the Knoll version. Also, are the mystery chairs vinyl or leather?

They are leather and from a CEO office in Munic.

Hi,
I removed the armrest and the screws look really not old. I think they have been changed
when the chair has been new uphostered. The screws that fix the wood frame to the
steel frame aren´t original too.

P.S.: the steel frame screws in my old chairs are original, they look like spax screws
