Will a couch (31x36x41 cm) fit through a 114 cm door?

A couch measuring 12 in × 14 in × 16 in fits through a door, with about 2 ft 7.5 in to spare at the tightest point. The binding dimension is width: in its best-fitting orientation, the width is what comes closest to the limit, and it still clears. We checked every orientation and confirmed at least one places the couch fully inside without compression or disassembly. That margin already subtracts a 1.5 in handling allowance, so it reflects a realistic load rather than a paper-thin theoretical fit. One caveat: applied practical clearance for handling (see tolerance buffer above).
