About the Aiways U6 2023 boot
The U6 boot is a square, straightforward space that loads easily. The opening is 39⅜″ wide by 26¾″ tall, the floor runs 39⅜″ with the seats up and 71¼″ folded, and the narrowest point across is 40⅛″. The useful detail is the sill. It sits 29½″ off the ground with only a ⅜″ drop to the floor, so the floor is effectively level with the lip. Heavy boxes slide straight in without a lift. Long flat cartons suit it once the bench is down. Push loads in from the bumper rather than carrying them over.
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.
