Will VITTSJÖ Shelf unit, black-brown/glass, 39 3/8x68 7/8 " 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.

VITTSJÖ ships as one long, flat carton, 79¼″ × 15¼″ × 3½″ and 60 lb 12 oz. The length is the awkward part: a rigid flat-pack just under 80 inches that will not bend around a tight boot mouth, and there is glass inside, so the box does not forgive a hard knock. A car that takes it easily is an estate, an SUV, or a hatchback with the rear seats folded flat. In anything smaller, load it diagonally from a folded seat back toward the boot, longest edge leading, and rest it on a blanket. Keep it printed side up so the glass shelves stay flat, and slide it in rather than drop it.
