KK48651 | Addition Sofa

The Addition sofa is a modular sofa comprising of two elements - one with and one without a back - that can be combined to create a complete seating arrangement for any space.

Designed by Kaare Klint.


Kaare Klint designed the Addition Sofa in 1933, originally inspired by a French rococo sofa. Klint wished to simplify it by designing a sofa with easily moveable sections that could be placed together as desired.

The first variant was created in the early 1930s for the influential New Carlsberg Foundation offices in Copenhagen. Klint went on refining the design, and the sofa quickly earned recognition for its simple construction and advanced upholstery.

The Addition Sofa without back is trimmed with piping to ensure beautiful, clean seams around the seat. The leather pleats create rhomboid panels that are held in place with leather-covered buttons and open up when pressure is applied to the sofa to keep the leather from overstretching.

The frame is produced in solid wood and the seat is upholstered with leather. 

The designer

Kaare Klint

Kaare Klint's influence as a professor at the Royal Academy of Fine Arts Furniture School in Copenhagen from 1924-54 led to a renewal of Danish furniture design. His teaching and designs were radical at the time as he focused heavily on functional analysis, the best materials and uncompromising craftsmanship.
