About the Aiways U5 2021 boot
Long flat packs suit the U5's boot. The floor runs 41″ with the rear seats up and 73¼″ with them folded, a gain of 32¼″. It is 40⅛″ wide at its narrowest, a little wider than the 39¾″ opening, so the opening sets the width limit. Above the loading sill there is 29⅛″ of clear height, enough to load a tall box upright. The harder part is the sill itself: it sits 29⅞″ off the ground, with the floor only ¾″ below. With a heavy box, ask a second person to take one end over the sill.
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.
