Will SLATTUM Upholstered bed frame, Vissle dark gray, Queen fit in a BMW X3 2022?

The X3 gives you a wide, level cargo bay. The hatch opens 44⅛ inches across and 31⅛ inches tall, and the floor holds 43¼ inches at its narrowest, so wide boxes that snag in smaller SUVs slide through here. Length is the catch: 37⅜ inches behind the seats, 70⅛ inches once they fold, a gain of +32⅝ inches. The floor sits level with the 27½ inch liftover, no drop on the far side, so a heavy carton pushes straight in. Save long flat-packs for seats-down trips; upright, the bay favors short, wide, stackable boxes. Slide heavy loads in across the sill and spare your back.

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.
