About the Kia Niro 2023 boot
Width is easy to judge in the Niro: the boot opening and the floor at its narrowest are both 41⅜″, so a wide box has the same room all the way in. Above the loading sill the opening is 26″ high, which caps how tall a box can stand. Lengthwise, the floor is 32⅝″ with the rear seats up. Folding them adds 32¾″, for 65⅜″ in all. Some packs longer than 32⅝″ fit with the seats up, at an angle on their side. Past the sill the floor is 5⅞″ lower, so when you slide a box in, ease it down onto the floor instead of letting it fall.
About the KALLAX Shelf unit, white, 30 1/8x57 5/8″ package
One box sounds easy until you lift it. This KALLAX travels as a single 59″ × 15¾″ × 6½″ box that weighs 68 lb 5 oz, and all that weight sits in a long, narrow shape you cannot easily hold close to your body. Lying flat and straight, it needs 59″ of boot floor. On its side and at an angle, it can fit in a shorter boot. Use two people, and agree which way it goes in before anyone lifts, so the heavy part of the job happens only once. Then lift together on a count and carry it level.
