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 BRIMNES Cabinet with doors, white, 30 3/4x37 3/8 " package
The BRIMNES cabinet arrives as one flat box, 39″ × 16¾″ × 6″, weighing 72 lb 7 oz. The size is friendly; the weight is not. At 39″ long it clears the folded load floor of almost any car, and plenty of boots take it with the seats still up, so this is one of the easier IKEA packages to move by car. What catches you is lifting 72 lb of dense flat-pack over a sill on your own. Slide it on its long edge rather than carrying it flat, bring a second pair of hands for the kerb and the stairs, and protect the corners; chipboard shows every knock at the edges.
