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 FJÄLLBO Shelf unit, black, 20 1/8x53 1/2 " package

FJÄLLBO ships as one flat box, 53″ long by 14¾″ wide and just 3¾″ thick, at 24 lb 4 oz. The length is the only real problem: 53″ rarely clears a trunk opening with the seats up, so plan on folding the rear bench in anything smaller than a wagon. The box itself is a one-person carry, but the slim profile flexes if you hold it by one end; support the middle or carry it on edge. Angle it through the tailgate diagonally, long edge first, and let it lie flat on the folded floor. Check the label against your order before you leave the racking aisle.
