About the Tesla Model Y 2023 boot

Fold the rear seats in the Model Y and the floor runs 76⅜″, a gain of 32⅝″ on the 43¾″ you get with them up. With the seats up there is room for several boxes, and some flat packs longer than 43¾″ fit too, on their side at an angle. The opening measures 39¾″ across by 27⅛″ high, and the floor is level with the 27½″ loading sill, so boxes slide in with no step. Tall boxes need to lie down to pass. The floor is narrower than the opening, at 37⅜″ at its narrowest, so check a wide box against the floor, not the 39¾″ opening.

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.
