About the Cupra Formentor VZ 2023 boot
The Cupra Formentor VZ gives you a compact performance SUV boot: an opening 39″ wide × 27½″ tall, a floor 31⅞″ long with the seats up, and 39⅜″ across at its narrow point. Fold the rear bench and the floor grows to 62⅝″, a gain of 30¾″, so the car nearly doubles its length once the seats drop. The tight point is that 39″ opening. Wide or long loads have to go in on a diagonal, and tall boxes are capped by the 27½″ height. It takes medium cartons and folded flat-packs well, but not full-length wardrobe frames. Fold the seats first, feed long boxes corner in, and mind the 4⅜″ lip.
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.
