About the Mazda CX-5 2023 boot

The CX-5's cargo opening measures 41¾″ wide by 31⅛″ tall, with 37¾″ of floor behind it when the seats are up. Fold the bench and the floor stretches to 66⅞″, a gain of 29⅛″, which is what makes longer loads possible at all. The floor holds 41⅜″ at its narrowest, so wide flat boxes lie level instead of wedging. Short, boxy loads fit fine seats up; anything long depends entirely on folding. The liftover sits at 29⅞″ with a 2″ drop to the floor, so lift heavier boxes clear of the sill rather than dragging them across it.

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.
