The Sofa 4000 by Rolf Benz is covered in dark blue leather and stands on floor-to-ceiling side panels. It is characterized by its classic design with wide armrests, generous padding and minimal curves. The seat of the two-seater can be expanded in depth by a few centimeters. 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
