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, black oak effect, 31 1/2x11x79 1/2″ package
You get the black oak effect BILLY in a single box, 81¼″ long, 11¾″ wide and 5″ thick. It weighs 86 lb 15 oz, and over that length the weight is hard to control, so plan on two of you, one at each end. Lying straight, it needs 81¼″ of boot floor, though its width and thickness still matter. Lift together on a count, so neither of you takes the full weight, even for a second. Set it down the same way, both ends at once.
