About the Fiat 500 Cinquecento 2020 boot
The Fiat 500 Cinquecento 2020 carries a city-size trunk: the opening measures 31⅛″ wide × 35⅜″ tall, taller than it is wide, and the floor runs just 20⅞″ with the seats up. Fold the bench and it stretches to 46⅛″, a gain of 25¼″. Between the wheel arches you get 40⅛″, wider than the mouth itself, so every box must clear 31⅛″ first. The liftover sits 27½″ high with a 7⅞″ drop down to the floor. Groceries, duffels and one modest box ride fine; long flat-packs do not. Fold the seats before loading, and lower heavy boxes over the sill rather than dragging them.
About the KALLAX Shelf unit, white, 43 7/8x57 5/8 " package
The KALLAX shelf unit arrives as two packages, and the larger one measures 56½″ long, 16″ wide and 5″ thick. That length is what decides the car. The whole order weighs 95 lb 3 oz, so it is a two-person lift even though the boxes look thin. Flat-pack board has no give, so you cannot bend it around a wheel arch or a seat back. An estate or an SUV with the rear bench down handles it comfortably. Load the long box first, on its edge and angled towards the far corner, then slide the second one alongside.
