Will SLATTUM Upholstered bed frame, Vissle dark gray, Queen fit in a Peugeot 308 2022?

The Peugeot 308 gives you a hatchback boot that is short but usefully deep. The opening measures 37¾″ wide by 29⅛″ tall, and the floor runs 30¾″ with the seats up, stretching to 58¼″ once you fold the rear bench, a gain of 27½″. The narrow point of the floor is 32¼″ across, so wide flat loads sit fine, but anything past 30¾″ long needs the seats down. The load lip sits 27½″ off the ground with a 6¾″ drop to the floor, so heavy boxes take a short lift then settle low. It takes suitcases and boxed furniture well, long flat-pack less so. Fold the seats before you load, not halfway through.

SLATTUM in Queen packs the whole upholstered frame into one long flat box: 65½″ × 29″ × 4″, weighing 81 lb 13 oz. The shape is the difficulty: over 65″ long, wide enough to argue with most trunk openings, and heavy enough that the thin box flexes when carried by the ends. It suits an SUV, a wagon, or any car with the rear seats folded flat. Feed it in low corner first on the diagonal and support the middle as you slide: the packaging gives up at the handholds long before the frame inside is at risk.
