About the Mercedes Benz A-Class 2019 boot
A box needs to clear 37″ by 24⅜″ to get into the A-Class: the width of the tailgate opening and its clear height above the loading sill. That height is what holds back tall boxes. Inside, there is more room: the boot is 28¾″ tall from its floor, which sits 4⅜″ below the 25⅝″ sill, and the floor is 39″ at its narrowest. The floor is 32¼″ long until you fold the rear seats, which adds 27¼″ and gives long flat packs 59½″. Laid across the boot, a box can be at most 37″ long, the width of the opening. With the seats up, some longer ones still fit at an angle, on their side.
About the KALLAX Shelf unit, white, 43 7/8x57 5/8″ package
Two boxes of equal length make up this KALLAX. One is 56½″ × 16″ × 5″ at 53 lb, the other 56½″ × 16¼″ × 4¾″ at 43 lb 3 oz. Measured along the floor, the boot has to give 56½″ for either box to lie straight. Thin boxes like these offer your hands little to hold, so most of the effort is the weight. Because they share a length, stacking them for one trip is tempting. Resist it: that is 96 lb 3 oz in a single lift. Carry them one at a time.
