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 FJÄLLBO Shelf unit, black, 20 1/8x53 1/2″ package
Everything for this FJÄLLBO shelf unit is in one flat box: 53″ long, 14¾″ wide and just 3¾″ thick. It weighs 24 lb 4 oz, which is a lot for a box that thin, and the narrow edges give your hands very little to hold. For the box to lie straight, the boot needs 53″ of floor and 14¾″ across. Carry it upright on its long edge, tucked under one arm with your other hand under the bottom, so the weight hangs at your side and the corners stay off the ground.
