An office-use unit sofa designed to create a communication space by ‘bracketing’ its inhabitants like parentheses. Users can freely combine the seven sofa types and four table types into a variety of spaces with a finely tuned balance of openness and privacy, concentration and relaxation and individuals and groups. The sofas are composed of sharp outer lines and softer inner curves, so that they respect the mood of the office environment while providing for user comfort. The height of the backrests, relatively tall at 1400mm, provides visual privacy and dampens the surrounding noise, allowing for focussed conversations.
