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 1/8x57 5/8 " package
The KALLAX comes as a single flat carton, 59″ × 16″ × 6½″, and it carries real weight at 68 lb 5 oz for one box. It is a stiff, square-edged panel pack: not long enough to be unmanageable, but wide at 16″ and heavy enough that you will not want to hold it out at arm's length. A hatchback with the rear seats folded usually takes it, and an estate or SUV takes it without thinking. The weight is the thing to plan for. Keep it flat, slide it across the boot floor, and load it last.
