COR Sinus Lounge Chair with Ottoman with or Without Arms in Fabric or Leather

Cor is Latin for heart, and COR furniture exemplifies the qualities at the heart of exceptional design: practicality, comfort and style. The company's sofas, lounge chairs and coffee tables capture the essence of the best of mid-century modernism. Simple silhouettes, quality materials and function-first designs ensure that vintage COR furniture is still in high demand with collectors all over the world.

COR was founded in Rheda-Wiedenbrück, Germany, in 1954 by Leo Lübke — in the name of his son, Helmut — and the Prince of Bentheim-Tecklenburg, a northern German county. Nearly a couple of decades prior, in 1937, a manufacturer of bedroom furniture called Interlübke was established by Leo and his brother Hans. The latter’s son Horst, who was managing partner from 1972, retired during the 1990s and his son Helmut Lübke joined Interlübke and shifted the brand’s focus toward modular furniture systems. During the 1980s, the Prince of Bentheim-Tecklenburg left COR and the Lübke family became its sole owner. In 2006, COR-Interlübke retail locations opened their doors.

COR made its mark in 1959 with a sleek modular seating system consisting of five parts called Quinta, which was created by designer Michael Bayer. The upholstered line boasted clean, angular contours and appealed to the day's ever-broadening flexible interior design sensibilities. It remained in production until 1978. The success of the Quinta was followed by the 1964 Conseta system, which featured a sofa and other pieces of seating designed by Friedrich Wilhelm Möller. 

The following decades saw more successful collaborations with designers like Peter Maly and Luigi Colani. The latter, a German industrial designer born Lutz Colani, created a range of gorgeous organically shaped Space Age seating for BASF and Fritz Hansen, serveware for Rosenthal and worked on automobile designs for Fiat. Colani designed the popular Orbis line for COR during the 1970s. 

In 2000, the Arthe sofa by Wulf Schneider was awarded the prestigious Red Dot Award from the North Rhine-Westphalia Design Centre.

COR is still owned and operated by the Lübke family’s parent company Gebrüder Lübke GmbH & Co. KG and continues to produce furniture at the Rheda-Wiedenbrück factory, sourcing leather from southern Germany and upholstery from Italy. The company partnered with Jehs+Laub, a renowned Stuttgart-based studio, in 2010.
