Will VÅGSTRANDA Pocket spring mattress, medium firm/white, Queen fit in a Volvo XC40 2023?

The XC40 boot is an upright, square space rather than a long one. Seats up, you get 35⅞″ of floor behind a 41¾″ wide by 28¾″ tall opening, so wide boxes slide in but long ones stall. Its best trait is the fold: drop the rear bench and the floor stretches to 66⅛″, a gain of 30⅜″. The floor narrows to 39¾″ at its narrowest, so tall flat boxes suit it better than very wide loads. The sill sits at 29½″ with no drop to the floor, so you push loads straight in at sill height instead of lifting over a lip.

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.
