Expert analysis
A couch measuring 47 in × 39 in × 33 in does not fit through a door, but it's about 3.5 in too large at the tightest point. The binding dimension is width: 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).
