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

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.
