By Lassen’s Ingeborg sofa is one of Danish architect Flemming Lassen’s designs from the 1940s. The petite sofa is named after Flemming and Mogens Lassen’s mother, artist Ingeborg Winding.

Typical of the designer, the sofa is simultaneously beautiful and sculptural yet also extremely functional: thanks to its small size, the graceful sofa can be placed anywhere without it dominating its surroundings. The charming sofa is upholstered in soft cotton blend fabric, making its inviting seat even more cosy – like a mother’s warm embrace!

Flemming Lassen

Flemming Lassen (1902-1984) was a Danish architect and one of the pioneers of Danish functionalism. He is best known for his buildings designed in collaboration with Arne Jacobsen as well as his internationally renowned furniture, some of which have been relaunched by the design company By Lassen founded by Lassen’s relatives. Perhaps the best known of Flemming Lassen’s designs is The Tired Man chair designed in 1935 for a competition held by the Copenhagen Cabinetmakers’ Guild.

Born into an artistic family, Flemming Lassen knew already at a young age that he wanted to become an architect, as did his brother Mogens. Flemming’s international breakthrough came at the end of 1920s when he won a competition held by the Federation of Danish Architects with his design for the House of the Future created in collaboration with Arne Jacobsen. The two continued their partnership also later in their careers.
