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

The VÅGSTRANDA Twin arrives roll-packed as a single dense block, 43¾″ × 18¼″ × 17½″, weighing 69 lb 4 oz. The shape is friendly, the weight is not: it is a compressed pocket spring mattress, so all of that mass sits in a stubby bundle with no handles and a wrap that likes to slip. Because its longest edge is 43¾″, most hatchbacks swallow it with a seat folded, and many boots take it outright. Carry it with two people, load it on its long side, and leave the wrapping sealed until it is in the bedroom: once it unrolls, it never goes back.
