WillBISSA Shoe cabinet with 3 compartments, white, 19 1/4x11x53 1/8 "fit in aAudi A3 Sportback 2024?

The Audi A3 Sportback boot is wide and square, better for bulk than for length. The opening is 38¼″ wide by 30⅜″ tall, and the narrow part of the floor still holds 39″ across, which is generous for this class. Seats up you get 30⅜″ of floor length, folding the rear bench takes that to 58⅝″, a gain of 28⅜″. The load lip is a low 26⅜″ with only a 6¼″ drop to the floor, so lifting boxes in is easy on your back. It swallows wide boxes, crates and a couple of cases side by side, but long flat-packs still need the seats folded. Load your widest item flat on the floor first, then build up.

BISSA ships as a single flat box, 54¼″ × 16¾″ × 3″, and it weighs 45 lb 15 oz. At 3″ thick it slides into gaps a built cabinet never would, so the thickness is not your problem. The length is. At 54¼″ you need a trunk that measures long enough on the floor, or one rear seat folded so the box can run forward between the seats. Most hatchbacks take it with the seats down, and any wagon or SUV swallows it flat. Lift it on edge with two hands, and rest it on a long edge rather than a corner, because 45 lb 15 oz of flat pack lands hard and the corners split first.
