About the Ford Focus 2023 boot
The Ford Focus boot is a compact hatchback space that rewards folding. Seats up, you get about 30⅜″ of floor length, fine for shopping runs, cases and small boxes. Fold the rear bench and it stretches to 61″, a gain of 30¾″, which is where flat-pack boxes start to fit. The mouth is 39⅜″ wide by 31½″ tall, and the floor narrows to 39¾″, so long slim packages ride better than tall bulky ones. The sill sits 27⅛″ high with a 7⅛″ drop to the floor, so lift over the lip, then slide the load down and forward.
About the BILLY Bookcase, black oak effect, 31 1/2x11x79 1/2 " package
The BILLY bookcase comes as a single long, flat box: 81¼″ × 11¾″ × 5″ and 86 lb 15 oz. It is the length that catches you out, not the weight on its own. That long panel wants a flat floor, which on most cars means folding the rear seats first. The board is rigid and will not flex around a wheel arch or a short boot, so it has to lie straight. An estate, a folded-seat hatchback, or an SUV takes it comfortably. Load it long-edge first, keep it flat, and guard the corners, because a knock at this weight cracks the edge.
