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 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.
