Is it a couch, lounger, or sectional? The Fossa sofa from COR is all of the above. Created by French designer Aurélien Barbry, this unusual piece of furniture functions according to the principle of change. Not only Fossa can be used as a building block for creating different configurations, the very structure of it is also adjustable. The cushions are placed in recesses. They are inserted, moved or removed, which makes Fossa even more dynamic. These recesses, when not filled with cushions, can be used to store books, magazines and other small items. And with plentiful color combinations available, the Fossa sofa can be customized to fit any design whim.
