About the Kia Niro 2023 boot
The Kia Niro 2023 opens wide at 41⅜″ across and 31⅞″ tall, so squeezing a box through the mouth is rarely what stops you. The limit is floor depth. With the rear seats up you get 32⅝″, tight for long boxes, but drop the bench and it stretches to 65⅜″, a gain of 32⅝″. The floor holds 41⅜″ across at its narrowest, so flat packages sit side by side. The load lip is high at 29⅛″ with a 5⅞″ drop to the floor, so lift over the sill, then slide long flat loads in with the seats folded.
About the KALLAX Shelf unit, white, 30 1/8x57 5/8 " package
The KALLAX comes as a single flat carton, 59″ × 16″ × 6½″, and it carries real weight at 68 lb 5 oz for one box. It is a stiff, square-edged panel pack: not long enough to be unmanageable, but wide at 16″ and heavy enough that you will not want to hold it out at arm's length. A hatchback with the rear seats folded usually takes it, and an estate or SUV takes it without thinking. The weight is the thing to plan for. Keep it flat, slide it across the boot floor, and load it last.
