Help needed to identify early Milo Baughman for Thayer Coggin Chairs?  

Thayer Coggin did use that rubberized material on at least some of their Danish modern frame chairs, and it's not that common. I would say it most likely is TC. I hear that they're friendly and helpful in identifying rheir products if you email them with pictures.

Thanks - you know I went all around their website and cannot for the life of me find a contact email address. any ideas how to find it?
I found a similar chair on 1stdibs - a high back version with same lower frame. That is what made me think of this.

Someone at Thayer Coggin will be happy to help you authenticate these chairs, just use the contact form on the Thayer Coggin website, located by hitting the "find a store" button or "where to buy" button and include you question in the comment, question section of the form. If you are a facebook user, you can also message Thayer Coggin via our facebook page.

I gave the head office a call and nicely asked who might handle such a question, and they sent me right over to the person, who was extraordinarily helpful.

Thanks everyone! I'll try Thayer Coggin direct from their site using suggested above.
