Abstract

A compactly packageable sofa includes a seat back, a seat cushion, two arm panels and a zippered flap. In the assembled state of the sofa, the seat cushion and the seat back are held between the arm panels, and the zippered flap is attached to both the seat back and the seat cushion. The seat back does not contact the seat cushion in the assembled state of the sofa. In the compact state of the sofa, the seat back, the seat cushion and the arm panels are not attached to one another. Instead, the arm panels fit inside a compartment under the seat cushion. The flap is not attached to both the seat back and the seat cushion in the compact state of the sofa. In the compact state, the sofa is contained in a packing box whose width is only slightly greater than the depth of the seat cushion.
