Friedrich Hill — Modular Sofa Model 144 for Walter Knoll, Germany, 1972

A striking and highly versatile six-piece modular sofa designed by Friedrich Hill for Walter Knoll in 1972, representing the bold comfort and relaxed forms of 1970s European design.
The Model 144 modular system was created to allow flexible arrangements, making it ideal for both large living spaces and dynamic interiors. Each element can be configured in multiple layouts, enabling the sofa to adapt to different rooms and seating needs.
This example showcases the distinctive design language of the period — low, generous proportions, deep seating and softly sculpted cushions that create an exceptionally comfortable lounging experience. The continuous padded backrests and wide seats emphasise relaxation while maintaining a clean architectural silhouette.
The sofa is upholstered in a rich olive-green fabric, a colour perfectly aligned with the earthy palette typical of 1970s interiors. The modular construction also allows the pieces to be used separately as lounge chairs or combined into a larger sectional configuration.
