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 VITTSJÖ Shelf unit, black-brown/glass, 39 3/8x68 7/8″ package
The VITTSJÖ shelf unit packs into one long, narrow box, 79¼″ × 15¼″ × 3½″, and it weighs 60 lb 12 oz. Its glass travels in that same box. The length makes the box hard to turn, and with glass inside, a knock or a drop can break something. For it to lie flat and straight, the box needs 79¼″ of boot floor and 15¼″ across. Carry it with two people and take every turn slowly. Once it is in the boot, push a blanket or soft bags into the gaps around it, so the box cannot shift on the drive.
