Martin Visser designed the sofa BR 02.7 in the late 1950's for Spectrum and found at ID Chicago

 

The sofa has been in production ever since. In 1988, the loose armrest was added. A simple movement converts the sofa into a sofa bed. The sofa and armrest are available in the fabric of your choice. However, because of the austere shape of the design, the use of an elastic fabric is recommended. The frame is made of matt chrome-plated metal.
