Expert analysis
A couch measuring 10 ft 3 in × 12 ft 10 in × 28 ft 7 in does not fit through a door, but it's about 11 ft 11.5 in too large at the tightest point. The binding dimension is height: that is the axis where the couch runs out of room. We checked every orientation, and none places the couch fully inside. One caveat: applied practical clearance for handling (see tolerance buffer above).
