About the Alfa Romeo Giulia 2019 boot
Flat boxes suit the Alfa Romeo Giulia 2019 boot, and the numbers show why. It has a boot lid, so you lower boxes in from above, and the whole boot is 18½″ tall. The opening is 37⅜″ wide, the floor narrows to 26⅜″, and it runs 37″ with the rear seats up. Fold them and the floor gains 31⅛″, reaching 68⅛″ for a long flat pack. Tall or bulky boxes are a poor match for a space this low and narrow. Check the thinnest side of each box first: it has to be 18½″ or less to fit under the boot lid.
About the BILLY Bookcase, oak effect, 31 1/2x11x79 1/2″ package
Heavy and long is a hard mix, and the oak effect BILLY box is both: 81¼″ × 11¾″ × 5″, at 87 lb 5 oz. It is narrow, but that is far too much weight over that length for one person. Placed straight, the box spans 81¼″ of boot floor. Plan the lift before you make it: who takes which end, which way you walk, and where the box goes down. With 87 lb 5 oz between you, neither of you should have to change grip halfway.
