Will VÅGSTRANDA Pocket spring mattress, medium firm/white, Twin fit in a Mazda CX-5 2023?

The CX-5's cargo opening measures 41¾″ wide by 31⅛″ tall, with 37¾″ of floor behind it when the seats are up. Fold the bench and the floor stretches to 66⅞″, a gain of 29⅛″, which is what makes longer loads possible at all. The floor holds 41⅜″ at its narrowest, so wide flat boxes lie level instead of wedging. Short, boxy loads fit fine seats up; anything long depends entirely on folding. The liftover sits at 29⅞″ with a 2″ drop to the floor, so lift heavier boxes clear of the sill rather than dragging them across it.

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.
