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 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.
