Will VÅGSTRANDA Pocket spring mattress, medium firm/white, Queen fit in a Citroen Berlingo 2018?

The Citroen Berlingo gives you a proper van-style boot: a wide, square opening at 47¼″ wide × 39⅜″ tall and a flat floor that stays 47¼″ across at its narrowest. Seats up the floor runs 39″, short for long boxes, but fold the bench and it stretches to 69¼″, a gain of 30⅜″. The load sill sits 22½″ up with no drop to the floor, so you slide boxes straight in rather than lifting them down. It handles wide, bulky and multi-box loads happily. For anything longer than a couple of feet, fold the bench first and load flat.

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.
