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 KALLAX Shelf unit, white, 43 7/8x57 5/8 " package
The KALLAX shelf unit arrives as two packages, and the larger one measures 56½″ long, 16″ wide and 5″ thick. That length is what decides the car. The whole order weighs 95 lb 3 oz, so it is a two-person lift even though the boxes look thin. Flat-pack board has no give, so you cannot bend it around a wheel arch or a seat back. An estate or an SUV with the rear bench down handles it comfortably. Load the long box first, on its edge and angled towards the far corner, then slide the second one alongside.
