WillBISSA Shoe cabinet with 3 compartments, white, 19 1/4x11x53 1/8 "fit in aTesla Model Y 2023?

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.

BISSA ships as a single flat box, 54¼″ × 16¾″ × 3″, and it weighs 45 lb 15 oz. At 3″ thick it slides into gaps a built cabinet never would, so the thickness is not your problem. The length is. At 54¼″ you need a trunk that measures long enough on the floor, or one rear seat folded so the box can run forward between the seats. Most hatchbacks take it with the seats down, and any wagon or SUV swallows it flat. Lift it on edge with two hands, and rest it on a long edge rather than a corner, because 45 lb 15 oz of flat pack lands hard and the corners split first.
