About the Audi Q3 2019 boot
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.
About the BRIMNES Cabinet with doors, white, 30 3/4x37 3/8 " package
The BRIMNES cabinet arrives as one flat box, 39″ × 16¾″ × 6″, weighing 72 lb 7 oz. The size is friendly; the weight is not. At 39″ long it clears the folded load floor of almost any car, and plenty of boots take it with the seats still up, so this is one of the easier IKEA packages to move by car. What catches you is lifting 72 lb of dense flat-pack over a sill on your own. Slide it on its long edge rather than carrying it flat, bring a second pair of hands for the kerb and the stairs, and protect the corners; chipboard shows every knock at the edges.
