The Fossa sofa also happens to be a lounger, a bed or a corner sectional depending on your wishes. We’re actually looking at a modular couch that can be rearranged whenever you feel like going for a new sofa design. The Fossa, although not the only modular sofa out there, is definitely unique and could be very well considered for all sorts of interior design ideas. The sofa is also a great addition to small homes too as it can also act as an improvised bed since all of its cushions can be rearranged in any way you see fit. Therefore it could act as a comfortable bed at night and then as a full-sized sofa during the rest of the day.
