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, 16 3/8x57 5/8″ package
A slim box can still be a two-person job. This KALLAX is one box of 60¾″ × 16″ × 4¾″ that weighs 39 lb 11 oz, and its length is what makes it awkward. A box this long is hard to steer on your own, and the far end goes where you cannot see it. Lying flat and straight, it needs 60¾″ of boot floor. Turned on its side and angled across the floor, it can fit in a shorter boot. Ask someone to take the far end, even for the short walk to the car, and let them guide it in while you push.
