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 VITTSJÖ Shelf unit, black-brown/glass, 39 3/8x68 7/8″ package
The VITTSJÖ shelf unit packs into one long, narrow box, 79¼″ × 15¼″ × 3½″, and it weighs 60 lb 12 oz. Its glass travels in that same box. The length makes the box hard to turn, and with glass inside, a knock or a drop can break something. For it to lie flat and straight, the box needs 79¼″ of boot floor and 15¼″ across. Carry it with two people and take every turn slowly. Once it is in the boot, push a blanket or soft bags into the gaps around it, so the box cannot shift on the drive.
