Beautiful c684 sofa in original sage green kvadrat fabric, which was designed in 1968 by kho liang ie for artifort (the netherlands). artifort is known for their high comfort combined by beautiful designs by great designers, the c683 is a nice example of such, as this relax sofa features a slanted angle of the frame and the large seating cushion to enhance comfort. The characteristic curved metal legs of this c683 sofa are in black, which shows a striking contrast with the colorful upholstery. A nice minimalist and iconic design, which will bring any space colour and comfort. I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution
