About the Citroen C3 Aircross 2019 boot
The C3 Aircross trunk is short on floor and generous on height. The mouth measures 39⅜″ wide by 34¼″ tall, taller than most small SUVs offer, while the seats-up floor is only 28¾″ deep. Fold the bench and the floor grows to 56¼″, a gain of 27½″ that turns a grocery trunk into a usable flat-pack space. Width between the arches is 37⅜″, and the sill sits 27½″ up with a 4⅜″ drop inside. Tall boxes ride upright here better than in rival crossovers; long boxes need the seats down every time. Slide heavy loads over the sill instead of lifting them clear.
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.
