OMKSTAK Stacking Chair by Rodney Kinsman

Designed in 1971 OMKSTAK is an all steel lightweight stacking chair, comprising a tubular frame and pressed steel seat and back. The monocoque seat panel provides the main structural element, eliminating the need for cross rails. Punched holes with turned down flanges reduce weight and add strength. The back panel incorporates a handle, allowing single-handed stacking of up to 25 seats without a rack.
