Does a Flat-pack bookcase box fit in a Kia Niro?

Doesn't fit

No. In none of the six orientations does the Flat-pack bookcase box fit in the Kia Niro boot with the parcel shelf in place. Folding a rear seat down or removing the shelf may still work, but that is no longer "it fits".

Drawn to scale. We ignore rounded corners and the shape of the wheel arches, which is why the answer errs on the cautious side.
