About the Citroen C3 2023 boot
In the C3's boot, the opening is the part to plan around. It is 34⅝″ wide with 22″ of clear height above the loading sill, while behind it the boot is 31⅛″ tall from its floor and the floor is 37¾″ wide at its narrowest. So a tall box has to lie down, even with more room inside. The sill is 30¾″ high, with the floor 9″ below it. The floor is 26⅜″ long with the rear seats up, which suits small boxes. Folding them gives you 53½″ of floor (27⅛″ more) for flat packs. Measure your box's height against that 22″ before you lift it.
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.
