About the Citroen C3 2023 boot

The C3 gives you a small supermini boot built for shopping and cabin bags, not long flat-pack. The opening is 34⅝″ wide by 31⅛″ tall, and the floor runs just 26⅜″ deep with the seats up. Fold the rear bench and it stretches to 53½″, a useful gain of 27⅛″, though the floor stays narrow at 37¾″. Tall or short boxes are fine; anything long fights the short floor. Note the high 30¾″ sill with a 9″ drop to the floor, so you lift up and over, then down into the well.

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.
