Will a couch (216x94x94 cm) fit through an 89 cm door?
Expert analysis
A couch measuring 7 ft 1 in × 3 ft 1 in × 3 ft 1 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).
