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 VÅGSTRANDA Pocket spring mattress, medium firm/white, Queen package
The Queen VÅGSTRANDA mattress weighs 111 lb 14 oz, all in one box of 66¾″ × 17¾″ × 17¼″. Its ends are nearly square, so there is nothing to hook your fingers on: it is a long, heavy block that you carry from underneath. Inside the boot, the box takes 66¾″ of floor lying straight, 17¾″ across and 17¼″ of height. Move it to the car on a flat trolley, so the only lift is the last short one into the boot, and make that lift with two people, together on a count.
