Thank you for visiting knoll.com.
We appreciate your interest in Brno.
Yes, we did make some brass Brno chairs in the 1980's as specials. We did
not keep very good records of our special during that time so there is no
paperwork I can forward to you.
The Knoll commitment to innovation and modern design has resulted in a
comprehensive portfolio of office systems, seating, files and storage,
tables, desks, textiles and accessories.
We look forward to your returning to knoll.com, where searching for
workplace furnishings is easy and inspiring.
