About the VW Passat Variant 2024 boot
Two numbers matter most in the Passat Variant's boot: 79⅛″ of floor with the rear seats folded, and 27½″ of clear height above the loading sill. The first suits long flat packs. The second sets the limit for tall boxes. With the seats up you still get 44½″ of floor for several boxes, and folding adds 34⅝″. The opening is 41⅜″ wide, the floor is 39¾″ at its narrowest, and the boot is 31⅛″ tall from its floor. The loading sill is 25¼″ high, with the floor 3½″ below it. A long flat pack up to 27½″ wide can also travel on its side, which makes it narrower when it has to angle across 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.
