About the Alfa Romeo Mito 2010 boot
A big lift comes first in the Mito: its loading sill is 31⅞″ high, and the floor sits 13″ below it. The boot is 32⅝″ tall from the floor, but the opening above the sill is just 19⅝″ high and 31½″ wide. Inside, the floor is wider, at 38⅝″ across its narrowest point. So size every box by the opening, not the space behind it. From the sill to the upright rear seats the floor is 26¾″, and 50⅜″ with them folded, which suits low boxes and short flat packs. Keep each box level as it clears the sill, then set it down the 13″ onto the floor.
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.
