Will VÅGSTRANDA Pocket spring mattress, medium firm/white, Queen fit in a Fiat 500 Cinquecento 2020?

The Fiat 500 Cinquecento 2020 carries a city-size trunk: the opening measures 31⅛″ wide × 35⅜″ tall, taller than it is wide, and the floor runs just 20⅞″ with the seats up. Fold the bench and it stretches to 46⅛″, a gain of 25¼″. Between the wheel arches you get 40⅛″, wider than the mouth itself, so every box must clear 31⅛″ first. The liftover sits 27½″ high with a 7⅞″ drop down to the floor. Groceries, duffels and one modest box ride fine; long flat-packs do not. Fold the seats before loading, and lower heavy boxes over the sill rather than dragging them.

VÅGSTRANDA ships as one box, and it is a heavy one: 65¾″ × 17¾″ × 17¼″ at 109 lb 6 oz. IKEA rolls and compresses the queen mattress, so instead of a floppy slab you get a short, dense block that two people can carry and one person will regret. The length is friendly; the weight is the problem, and the box gives you no handles. Most hatchbacks take it with the rear seats folded, and a wagon or SUV swallows it without drama. Load it last, on its side, so it slides straight out at home, and keep the wrapping sealed until the bedroom: once it expands, it never rolls back up.
