Nineteen foam blocks stack into a 55" couch, then break apart into forts, tunnels, ramps or a floor bed, so the same set holds a child's interest far longer than a fixed sofa. Velvet covers unzip and go in the wash after the inevitable spills. High-density foam gives enough support for climbing and jumping while staying light at 14 lbs in total. No assembly is needed and no tools are involved. Suitable for children of three and up; overall 55" x 23.5" x 20" when built as a couch.
