About the BMW 1 Series 2020 boot
The 1 Series boot is short and low rather than deep. With the seats up the floor gives you 29½″, which is the constraint on most flat-pack runs, and the opening measures 37⅜″ wide by 26″ tall. Fold the rear bench and the floor almost doubles to 57½″, a gain of 28″. The floor is 40⅛″ across at its narrowest, so width is rarely your problem. The sill sits at 27½″ with a 3⅛″ drop, which makes this one of the easier hatchbacks to load. Fold the seats first, load long, then fill the gaps.
About the KALLAX Shelf unit, white, 16 3/8x57 5/8 " package
The KALLAX travels as one long, flat carton: 60¾ inches by 16 inches, just 4¾ inches thick, at 39 lb 11 oz. The length is the whole challenge. A box this long clears very few trunk openings with the rear seats up, so plan on folding them before you leave the driveway. A wagon or mid-size SUV with the bench down takes it flat on the floor; a small hatchback needs it angled between the wheel arches. Particleboard this heavy flexes in a slim sleeve, so carry it on edge with a hand at each end, and rotate it diagonally through door frames instead of pushing it square.
