About the Tesla Model Y 2023 boot
The Model Y boot is long and flat, with a deep floor even before you fold. The opening is 39¾″ wide × 27⅛″ tall, and the floor already runs 43¾″ with the seats up, stretching to 76⅜″ folded, a gain of 32⅝″. The sill height is 27½″ with a 0″ drop, so the floor sits level with the lip and items slide straight in. The opening is on the low side, so tall boxes can catch on the way through. It is excellent for long flat-packs and big shops, less so for very tall items. Lead with the long edge and slide it in flat.
About the KALLAX Shelf unit, white, 16 3/8x57 5/8 " package
The KALLAX travels as one long, flat carton: 60¾ inches by 16 inches, just 4¾ inches thick, at 39 lb 11 oz. The length is the whole challenge. A box this long clears very few trunk openings with the rear seats up, so plan on folding them before you leave the driveway. A wagon or mid-size SUV with the bench down takes it flat on the floor; a small hatchback needs it angled between the wheel arches. Particleboard this heavy flexes in a slim sleeve, so carry it on edge with a hand at each end, and rotate it diagonally through door frames instead of pushing it square.
