About the Mazda CX-5 2023 boot
Width barely changes from the CX-5's tailgate to its floor: 41¾″ at the opening and 41⅜″ at the floor's narrowest point. Tall boxes do well too, with a 29⅛″ clear gap over the loading sill and a floor only 2″ below the sill, so the boot is 31⅛″ tall from its floor. The floor runs 37¾″ with the rear seats up and 66⅞″ with them down. With the seats up, some boxes longer than 37¾″ still fit at an angle, on their side. Get a second person for heavy boxes: the sill sits 29⅞″ off the ground.
About the BRIMNES Cabinet with doors, white, 30 3/4x37 3/8″ package
Small box, serious weight. The BRIMNES cabinet packs 72 lb 7 oz into a single box of 39″ × 16¾″ × 6″, and something that compact and heavy is easy to underestimate. Lying flat, it sits on a patch of floor 39″ by 16¾″. The lift is where the care goes. Short as the box is, that weight is a lot to hold while you lean into the boot. Take it as a pair, knees bent and backs straight, and lower it gently all the way down rather than letting it drop the last bit.
