C1.1 is the base version of this chair, with a slender look and a strong core. It has been realized in two versions, all based on a common tubular steel frame.The 1/1 version has got seat and back in full metal sheet. The version 1/4, is again completely in painted metal with carved seat and back, giving the chair an even  lighter appearance.
