About the Aiways U5 2021 boot
Long flat packs suit the U5's boot. The floor runs 41″ with the rear seats up and 73¼″ with them folded, a gain of 32¼″. It is 40⅛″ wide at its narrowest, a little wider than the 39¾″ opening, so the opening sets the width limit. Above the loading sill there is 29⅛″ of clear height, enough to load a tall box upright. The harder part is the sill itself: it sits 29⅞″ off the ground, with the floor only ¾″ below. With a heavy box, ask a second person to take one end over the sill.
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.
