About the Citroen C5 Aircross 2021 boot
The C5 Aircross boot has a big opening: 104 cm wide, with 74 cm of clear height above the loading sill. The floor sits just 4 cm below the sill and stays 106 cm wide at its narrowest, so boxes slide in almost level. With the rear seats up you have 97 cm of floor, room for several boxes side by side or a box up to 74 cm tall standing upright. Lying flat and straight, a box longer than 104 cm needs the seats folded, even turned across the boot. Folding them gives you 172 cm of floor. The work is in the lift: the sill is 74 cm off the ground. Rest each box on the sill first, then push it in.
