COR Sinus lounge chair, originally designed in 1976 by Reinhold Adolf and Hans-Jürgen Schröpfer for COR Germany. The design is composed of rhythmic cylindrical leather cushions suspended within a polished chrome frame, giving the chair an almost floating appearance. Its deep seat and relaxed reclining angle provide exceptional comfort, while the exposed steel structure creates a refined contrast with the soft upholstery. Executed in black leather with subtle signs of age and use that add depth and character to the surface. A strong yet understated design that effortlessly balances comfort with a graphic architectural presence. In good vintage condition with minor wear consistent with age and use.
