Such a great history behind these chairs and they are made from 80% recycled aluminium, which means they're incredibly light. Read about the history here
The top image is in the kitchen of one of my clients. We source them from Thonet in Wellington, as well as the Dairy Table the chairs are with. The middle one is an advertising agency in New York - check out the Emeco website for more images. And the last image is another dining scenario which I saw in Apartment Therapy.
