Will VÅGSTRANDA Pocket spring mattress, medium firm/white, Queen fit in a Peugeot 3008 2025?

The 3008 gives you a wide, square cargo area. The liftgate opening measures 40⅛″ wide × 30¾″ tall and the floor stays 39¾″ across at its narrowest, so you keep almost full width right to the back. With the rear seats up you get 39″ of floor, which suits boxed appliances and shorter flat packs. Fold the bench and you gain 26¾″, taking the floor to 65¾″, the biggest single change you can make here. The load lip sits 31½″ off the ground with a 4⅜″ drop to the floor, so lift high, then slide down and forward.

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.
