Will VÅGSTRANDA Pocket spring mattress, medium firm/white, Twin 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.

The VÅGSTRANDA Twin arrives roll-packed as a single dense block, 43¾″ × 18¼″ × 17½″, weighing 69 lb 4 oz. The shape is friendly, the weight is not: it is a compressed pocket spring mattress, so all of that mass sits in a stubby bundle with no handles and a wrap that likes to slip. Because its longest edge is 43¾″, most hatchbacks swallow it with a seat folded, and many boots take it outright. Carry it with two people, load it on its long side, and leave the wrapping sealed until it is in the bedroom: once it unrolls, it never goes back.
