Will VÅGSTRANDA Pocket spring mattress, medium firm/white, Twin fit in an Audi Q3 2019?

The Audi Q3 gives you a wide, square boot mouth: 44⅛″ across and 30¾″ tall, so most flat-pack cartons clear the opening with the seats up. Behind them the floor runs 35⅜″, and folding the rear bench stretches that to 65⅜″, a gain of 29⅞″ that turns a school-run boot into a proper load bay. The floor holds 39⅜″ across at its narrowest, so wide boxes sit flat. The catch is the lip: at 29½″ the sill is a high lift, with a 3½″ drop to the floor. Slide heavy boxes in on their edge rather than lowering them straight down.

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.
