About the Kia Sportage 2023 boot
The Sportage gives you a boot opening 41⅜″ wide and 28¾″ high, and the floor behind it is almost as wide: 41″ at its narrowest. The loading sill is 28⅜″ high, and the floor carries on at that same height. With the rear seats up the floor is 35⅜″ long, fine for a few wide boxes. A longer pack may still fit across it, or at an angle on its side. Folded seats add 31⅛″, for 66½″ of floor and room for a long pack. Start with the heaviest box: rest it on the sill, then slide it in level.
About the KALLAX Shelf unit, white, 43 7/8x57 5/8″ package
Two boxes of equal length make up this KALLAX. One is 56½″ × 16″ × 5″ at 53 lb, the other 56½″ × 16¼″ × 4¾″ at 43 lb 3 oz. Measured along the floor, the boot has to give 56½″ for either box to lie straight. Thin boxes like these offer your hands little to hold, so most of the effort is the weight. Because they share a length, stacking them for one trip is tempting. Resist it: that is 96 lb 3 oz in a single lift. Carry them one at a time.
