About the Hyundai Kona 2024 boot
The Hyundai Kona 2024 gives you a compact but usable hatchback boot. The opening is 41″ wide by 30¾″ tall, and the floor runs 33⅞″ deep with the seats up. Its strong point is folding: drop the rear bench and the floor almost doubles to 65⅜″, a gain of 31½″. The floor stays a full 41″ wide right to the back, so flat boxes lie square. The sill sits 26¾″ off the ground with only a 2″ drop inside, so sliding heavy boxes in is easy. Long frames beyond 65⅜″ will not go, but most flat-pack cartons will. Load the longest box first, flat on the floor.
About the BILLY Bookcase, oak effect, 31 1/2x11x79 1/2 " package
The BILLY bookcase ships as one long, flat, heavy box: 81¼″ × 11¾″ × 5″ and 87 lb 5 oz. The length is the challenge, not the bulk. That long panel needs floor space most boots only find with the rear seats down. The flat-pack board is rigid, so it will not bend around a wheel arch or curl into a short boot. An estate, a hatchback with the seats folded, or an SUV handles it best. Slide it in long-edge first, low and flat, and protect the corners, because at this weight a dropped end can split the board.
