Start with a straight sofa for everyday use, then pull the three armless chenille pieces into a U when friends come over, or push them together into a bed for a guest. Each piece is 58 inches wide and 27.75 deep, and together they seat six.
Under every seat cushion sits a panel that lifts out to reveal storage. The back and arm cushions are interchangeable, and plastic clips lock neighboring pieces so no gap opens between seats. Your seat is 19.75 inches high and 22 deep. The pieces arrive as parts, though, and putting them together is a job for you, with the included instructions.
