About the BMW X3 2022 boot
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.
About the KALLAX Shelf unit, white, 30 1/8x30 1/8 " package
The 2x2 KALLAX is one of the easiest IKEA packages you will carry: a single flat box of 31¾″ × 16¼″ × 7½″ at 37 lb 8 oz. At under 32″ long it fits in nearly any trunk without folding a seat, small hatchbacks included. The weight is the only catch: it is dense for its size and the cardboard gives you no handholds. Carry it upright against your body rather than flat by the ends, and lay it on its wide face in the trunk so it cannot flip over on the first speed bump.
