Jason 390 Sofa

This is a Jason 390 sofa, produced by German manufacturer Walter Knoll/Coalesse. The sofa was designed in 1997 by EOOS, a trio of Austrian designers named Martin Bergmann, Gernot Bohmann and Harald Gründl. The three worked together to come up with the plans for this convertible sofa, allowing the silhouette to expand and change when more space is needed. The seats are upholstered in a soft grey material, and the frame of the sofa is done in smooth grey leatherette. It sits on a steel frame with 4 modernist legs.
The sofa measures 34.64 L, 84.65/110.6 inches wide, and 33 inches high. The piece is in great shape, having a few small rips in the leatherette, and some scuffs on the steel legs. Overall, this sofa is in very good condition. Please see photos.
