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 KALLAX Shelf unit, white, 30 1/8x30 1/8 " package
The 2x2 KALLAX is one of the easiest IKEA packages you will carry: a single flat box of 31¾″ × 16¼″ × 7½″ at 37 lb 8 oz. At under 32″ long it fits in nearly any trunk without folding a seat, small hatchbacks included. The weight is the only catch: it is dense for its size and the cardboard gives you no handholds. Carry it upright against your body rather than flat by the ends, and lay it on its wide face in the trunk so it cannot flip over on the first speed bump.
