About the Alfa Romeo 159 Turismo 2009 boot
The 159 Turismo loads from above, under a boot lid. So the full boot height applies at the opening. The side of a box that points up can be 21¼″ at most, and the side that goes across must fit the opening. The opening is 29½″ wide over a floor that is 33½″ wide at its narrowest. The floor is the strong point. It runs 40⅛″ with the seats up and 68⅞″ with the rear seats folded, and some boxes longer than the floor still fit at an angle, standing on their side. Lift each box clear of the 29⅛″ loading sill, then bend your knees and lower it all the way down rather than dropping 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.
