About the Citroen C5 Aircross 2021 boot
From the loading sill to the floor, the C5 Aircross boot is almost level: the floor sits only 1⅝″ lower. The opening is 41″ wide with 29⅛″ of clear height above the sill, and the floor stays 41¾″ wide at its narrowest. Seats up, you get 38¼″ of floor, enough for several boxes or a box up to 29⅛″ tall standing up. Some flat packs longer than 38¼″ fit as well, angled across the floor on their side. Folding the rear seats adds 29½″, for 67¾″ in total. The sill itself is 29⅛″ off the ground. Lift each box onto the sill, then slide it forward.
About the KALLAX Shelf unit, white, 30 1/8x30 1/8″ package
This KALLAX comes in one compact box of 32″ × 16″ × 7½″, and it weighs 37 lb 8 oz. That is a lot of weight for so small a box, and it is what makes the job awkward. Lying flat on the boot floor, it takes a space 32″ long, 16″ wide and 7½″ high. The risk sits in the lift, so bend your knees and get your hands under the bottom corners, not on its top edges. That keeps your grip under the weight the whole way into the boot.
