A Bubble sofa in a small living room is entirely possible, provided you choose the right size and placement. Opt for the 1 or 2-seater format rather than the 3-seater, and place it against a wall rather than in the center of the room to keep traffic areas clear.
Go for a light color that won't visually overwhelm the space, and avoid cluttering it with too many bulky pieces of furniture: a small coffee table and a rug are enough. If space is truly limited, the Bubble armchair alone can create a strong cocooning corner without taking over the entire living room.
The ultimate tip: take advantage of the fact that the sofa arrives compressed to assemble it directly in the room, even in an apartment with narrow access or no elevator—a real plus when space is at a premium right from the entrance.
