The de Sede / Hans Kaufeld leather sofa is an exceptional collector's item, bearing the signature of two legends of furniture design. Finished in timeless black, this two-seater embodies pure luxury and an almost architectural rigor, perfectly balanced by the soft upholstery. The collaboration between de Sede (Switzerland) and Hans Kaufeld (Germany) represents the absolute pinnacle of leather quality and meticulous craftsmanship. The design is characterized by its striking, deep silhouette and the flowing transitions between the backrest and armrests, giving the sofa a grounded and powerful presence. The manual function of this model is often a hidden technical highlight. The backrests can be folded out to provide comfortable head support. Folding them back down restores the sofa's compact appearance.
