About the Opel Corsa 2024 boot
With the rear seats up, the Corsa's boot floor is wider than it is long: 26″ long and 37¾″ wide at its narrowest. The opening is 33⅞″ wide, with 21⅝″ of clear height above the loading sill, while the boot is 28¾″ tall from its floor. That clear height is what makes tall boxes hard work here. The sill is 27½″ high, and the floor sits 7⅛″ below it. Folding the seats adds 26″, for 52″ of floor, the set-up for long flat packs. Before you fold them for a box longer than 26″, try it across the floor or at an angle, turned so it clears the 33⅞″ opening.
About the BILLY Bookcase, black oak effect, 31 1/2x11x79 1/2″ package
You get the black oak effect BILLY in a single box, 81¼″ long, 11¾″ wide and 5″ thick. It weighs 86 lb 15 oz, and over that length the weight is hard to control, so plan on two of you, one at each end. Lying straight, it needs 81¼″ of boot floor, though its width and thickness still matter. Lift together on a count, so neither of you takes the full weight, even for a second. Set it down the same way, both ends at once.
