About the Citroen C3 Aircross 2019 boot
The C3 Aircross boot is short on floor but generous on height. With the rear seats up you get 28¾″ of floor, 37⅜″ wide at its narrowest. Tall boxes suit it: the opening has 29⅞″ of clear height above the loading sill and is 39⅜″ wide, and from its floor the boot is 34¼″ tall. Fold the seats and the floor reaches 56¼″ (a gain of 27½″). A pack longer than 56¼″ will not go in straight, but a thin one may still fit diagonally, on its side. The loading sill is 27½″ high, with a 4⅜″ drop behind it. Check a tall box against the 29⅞″ above the sill, not the full 34¼″.
About the KALLAX Shelf unit, white, 43 7/8x57 5/8″ package
Two boxes of equal length make up this KALLAX. One is 56½″ × 16″ × 5″ at 53 lb, the other 56½″ × 16¼″ × 4¾″ at 43 lb 3 oz. Measured along the floor, the boot has to give 56½″ for either box to lie straight. Thin boxes like these offer your hands little to hold, so most of the effort is the weight. Because they share a length, stacking them for one trip is tempting. Resist it: that is 96 lb 3 oz in a single lift. Carry them one at a time.
