About the Alfa Romeo Giulietta 2017 boot
The Giulietta's boot is roomier than its opening. Inside, the floor never gets narrower than 40⅛″, but the opening is 35⅜″ wide with 21⅝″ of clear height above the loading sill. That sill sits 30⅜″ off the ground, so expect a real lift, and the floor is 8¼″ below it. Seats up, you get 29⅞″ of floor, which suits a couple of compact boxes. Fold the rear seats and you gain 28″, for 57⅞″ of floor, and some flat packs longer than that fit at an angle, on their side. Turn each box so the side facing up is 21⅝″ or less. Then check it against the floor as well as the opening: either one can stop it.
About the BILLY Bookcase, white, 31 1/2x11x79 1/2″ package
The white BILLY is packed in one long, narrow box: 81¼″ × 11¾″ × 5″. It weighs 88 lb 1 oz, and at that length you want a second person to carry it. Loaded end first, it asks little of the opening: only room for its 11¾″ by 5″ end. Lying flat and straight, it needs 81¼″ of floor for the longest side. On its side and at an angle, it needs less floor but more width at the opening, and the verdict on this page shows whether that works in your boot. Lift it level between the two of you and keep it that way until the whole box is in the boot.
