Two design classics by Warren Platner for Knoll International. Made in the 1960s. As can be seen in the pictures, the seat cushion and upholstery are missing. Both chairs were painted white some time ago. Both chairs are sturdy. This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution
