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 BILLY Bookcase, oak effect, 31 1/2x11x79 1/2″ package
Heavy and long is a hard mix, and the oak effect BILLY box is both: 81¼″ × 11¾″ × 5″, at 87 lb 5 oz. It is narrow, but that is far too much weight over that length for one person. Placed straight, the box spans 81¼″ of boot floor. Plan the lift before you make it: who takes which end, which way you walk, and where the box goes down. With 87 lb 5 oz between you, neither of you should have to change grip halfway.
