Will BRIMNES Cabinet with doors, white, 30 3/4x37 3/8 " fit in a Skoda Fabia 2023?

The Fabia gives you a wide mouth for a small car: 39⅜″ across and 32¼″ tall, a touch wider than the 36⅝″ of floor between the wheel arches behind it. With the rear seats up the floor is short at 29⅛″, enough for groceries and compact boxes; fold the bench and it opens out to 55½″, a gain of 26⅜″ that makes real flat-pack runs possible. You load over a 26¾″ liftover with a 7½″ drop down to the floor, so you lower cargo in rather than slide it straight through. Long rigid boxes fail at the opening first, so check your longest box against that, and ease heavy items down past the drop.

The BRIMNES cabinet arrives as one flat box, 39″ × 16¾″ × 6″, weighing 72 lb 7 oz. The size is friendly; the weight is not. At 39″ long it clears the folded load floor of almost any car, and plenty of boots take it with the seats still up, so this is one of the easier IKEA packages to move by car. What catches you is lifting 72 lb of dense flat-pack over a sill on your own. Slide it on its long edge rather than carrying it flat, bring a second pair of hands for the kerb and the stairs, and protect the corners; chipboard shows every knock at the edges.
