Will KALLAX Shelf unit, white, 43 7/8x57 5/8 " 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.

The KALLAX shelf unit arrives as two packages, and the larger one measures 56½″ long, 16″ wide and 5″ thick. That length is what decides the car. The whole order weighs 95 lb 3 oz, so it is a two-person lift even though the boxes look thin. Flat-pack board has no give, so you cannot bend it around a wheel arch or a seat back. An estate or an SUV with the rear bench down handles it comfortably. Load the long box first, on its edge and angled towards the far corner, then slide the second one alongside.
