A mattress measuring 80 in × 78 in × 16 in does not fit through a door, with about 1 ft 0.5 in to spare at the tightest point.
Your mattress will not clear the space — but only just — it is a hair over the limit at the tightest point. The passage is the limiting constraint.
Handling: The item exceeds the space in every orientation — standard entry won't work.

Margins shown are calculated; allow ±¼ in for tape-measure precision.
A door is a 2D opening — width and height matter; depth (path length through the doorway) doesn’t.
Tolerance ±¼ in (6 mm) is applied implicitly (band promotion to FITS_VERY_TIGHT) — see the note below the orientation matrix.
ItemFits fills in anything you don’t measure yourself. Whenever you see [standard], the real value in your home may differ — measure it and message us in the chat below; we’ll re-run the math.
