About the Ford Focus 2023 boot
There are two heights to know in the Focus. A box gets 24⅜″ of clear height above the loading sill on the way in. The boot itself is 31½″ tall from its floor, which sits 7⅛″ below the sill. So the gap, not the space inside, decides whether a tall box goes in upright. For width, the tailgate opening gives you 39⅜″ and the floor 39¾″ at its narrowest. Length is short with the rear seats up, at 30⅜″, and grows by 30⅝″ to 61″ with them folded. Put long packs in first and fit smaller boxes around them.
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.
