Will VÅGSTRANDA Pocket spring mattress, medium firm/white, Queen 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.

VÅGSTRANDA ships as one box, and it is a heavy one: 65¾″ × 17¾″ × 17¼″ at 109 lb 6 oz. IKEA rolls and compresses the queen mattress, so instead of a floppy slab you get a short, dense block that two people can carry and one person will regret. The length is friendly; the weight is the problem, and the box gives you no handles. Most hatchbacks take it with the rear seats folded, and a wagon or SUV swallows it without drama. Load it last, on its side, so it slides straight out at home, and keep the wrapping sealed until the bedroom: once it expands, it never rolls back up.
