Will an armchair (35"×35"×35") (89x81x86 cm) fit through a 91 cm door?
Expert analysis
A armchair (35"×35"×35") measuring 35 in × 32 in × 34 in fits through a door, with about 2.5 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 armchair (35"×35"×35") 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).
