About the Kia Sportage 2023 boot

The Sportage boot is wide and loads dead flat. The opening is 41⅜″ wide × 28¾″ tall, and the floor runs 35⅜″ with the seats up, reaching 66½″ folded, a gain of 31⅛″. At its narrowest the floor still measures 41″, so wide boxes go straight in without angling. The sill is 28⅜″ with a 0″ drop, so the floor sits level with the lip and items slide in without lifting. The opening is a touch low, so watch tall boxes through the gap. It is strong for wide and long loads, fold the seats for the longest flat-packs. Slide items along the flat floor rather than stacking high.

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.
