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 VIHALS Sideboard, white, 55 1/8x18 1/2x29 1/2 " package

The VIHALS sideboard ships as two flat boxes, the larger one 56¾″ long, 19″ wide and just 4″ thick. It is a long, flat, rigid panel set, and the pair together weigh 136 lb 11 oz, so weight is the real issue here, not bulk. A slim 4″ profile slides into most trunks, but the 56¾″ length wants an estate, a hatchback with the rear seats folded, or an SUV. Load the heavier box first and lay it flat, then the second on top. Protect the long edge with a blanket, and lift with two people, since 136 lb is a lot to move alone.
