Will BILLY Bookcase, white, 31 1/2x11x79 1/2 " fit in a Skoda Octavia Combi 2025?

A wagon body means one thing here: length. The opening measures 40½″ wide by 30¾″ tall, the load floor runs 42⅞″ with the seats up, and folding the bench takes it to 73¼″, a gain of 30⅜″. Between the wheel arches you still get 39⅜″ of width, so long flat boxes lie flat on the floor instead of angling across it. The catch is the 30¾″ opening height: tall cartons go in on their side or not at all. The lip sits 25¼″ off the ground with a 3⅞″ step down to the floor, so slide heavy boxes across the sill instead of lifting them over it, and load the longest box first.

The BILLY ships as one long, flat carton, 81¼″ × 11¾″ × 5″, and it is heavier than it looks at 88 lb 1 oz. The shape is the awkward part: long and only 5″ thick, a rigid panel box that will not bend or fold around a wheel arch. That length rules out most boots with the seats up. You want an estate, a hatchback with the rear seats folded, or an SUV that gives a flat run past the front seats. Two people make this easy. Carry it on edge, slide it in low, and rest the leading edge on something soft.
