Will BRIMNES Cabinet with doors, white, 30 3/4x37 3/8 " fit in a Volvo XC60 2022?

The XC60 gives you a wide, flat, square boot rather than a deep cave. The opening is 44⅛″ wide and 29⅛″ tall, and the floor runs 37¾″ with the rear seats up. Fold them and it nearly doubles to 70⅛″, a gain of 32¼″, so the seats-up length is the real limit on anything long. The floor stays a wide 43¾″ across at its narrowest, which suits flat boxes and multi-package loads. The lip is 28⅜″ off the ground but level with the floor inside, so you slide loads in rather than lift them over a step. For long flat-packs, fold the bench first and load down the middle.

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.
