About the Aiways U5 2021 boot
The U5 is one of the more forgiving boots to load. The opening measures 39¾″ wide by 29⅞″ tall, the floor runs 41″ with the seats up, and folding the bench takes it to 73¼″, a gain of 32¼″. Width holds at 40⅛″ at the narrowest point, so the space stays close to square. The sill sits 29⅞″ up with a ¾″ drop to the floor, near enough level to slide heavy boxes straight off the bumper. Long flat cartons suit it once the seats are down. Load those first, then pack around them.
About the VITTSJÖ Shelf unit, black-brown/glass, 39 3/8x68 7/8 " package
VITTSJÖ ships as one long, flat carton, 79¼″ × 15¼″ × 3½″ and 60 lb 12 oz. The length is the awkward part: a rigid flat-pack just under 80 inches that will not bend around a tight boot mouth, and there is glass inside, so the box does not forgive a hard knock. A car that takes it easily is an estate, an SUV, or a hatchback with the rear seats folded flat. In anything smaller, load it diagonally from a folded seat back toward the boot, longest edge leading, and rest it on a blanket. Keep it printed side up so the glass shelves stay flat, and slide it in rather than drop it.
