Will VÅGSTRANDA Pocket spring mattress, medium firm/white, Twin fit in a Seat Ibiza 2022?

The Ibiza's cargo area is compact and honest about it: the opening is 34⅝″ wide by 32¼″ tall, the floor gives you 26¾″ with the rear bench up, and folding it opens 55½″, a gain of 28¾″. Between the wheel arches you keep 39″, more than the opening is wide, so a box that clears the mouth can settle flat inside. It handles short stacked boxes well and long flat packs poorly; most rejections happen at the opening, not on the floor. The liftover sits 27⅛″ high with a 7½″ drop inside, so rest a heavy box on the sill edge and lower it in instead of pushing.

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.
