About the Audi A3 Sportback 2024 boot

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.

About the FJÄLLBO Shelf unit, black, 20 1/8x53 1/2 " package

FJÄLLBO ships as one flat box, 53″ long by 14¾″ wide and just 3¾″ thick, at 24 lb 4 oz. The length is the only real problem: 53″ rarely clears a trunk opening with the seats up, so plan on folding the rear bench in anything smaller than a wagon. The box itself is a one-person carry, but the slim profile flexes if you hold it by one end; support the middle or carry it on edge. Angle it through the tailgate diagonally, long edge first, and let it lie flat on the folded floor. Check the label against your order before you leave the racking aisle.
