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 KALLAX Shelf unit, white, 30 1/8x30 1/8 " package
The 2x2 KALLAX is one of the easiest IKEA packages you will carry: a single flat box of 31¾″ × 16¼″ × 7½″ at 37 lb 8 oz. At under 32″ long it fits in nearly any trunk without folding a seat, small hatchbacks included. The weight is the only catch: it is dense for its size and the cardboard gives you no handholds. Carry it upright against your body rather than flat by the ends, and lay it on its wide face in the trunk so it cannot flip over on the first speed bump.
