Will KARMSUND Floor mirror, black, 15 3/4x65 3/4 " fit in a Skoda Octavia 2013?

For a car this size the Octavia boot is long. Seats up you get 43¾″ of floor, more than most family hatchbacks, with an opening 36⅝″ wide and a generous 33⅛″ tall. The narrow point measures 39¾″, so wide boxes clear comfortably. Fold the rear bench and the floor reaches 73⅝″, a gain of 29⅞″, which takes most long flat-pack cartons. The sill sits 28″ up with a 7⅞″ drop to the floor, so there is a step down inside. Push long boxes right to the front and they settle below the lip.

One long, thin box: the KARMSUND mirror ships as a single package at 65″ × 16¼″ × 1¼″ and 21 lb. The weight is nothing; the shape is the whole job. A 65″ carton with glass inside cannot bend around a seat gap or ride upright, it wants one flat, straight run, and few cars offer that with the rear seats up. Fold the seats in a wagon, hatchback or SUV and the length usually clears. Feed a top corner through the opening first, lay the box flat on a blanket with the glass side up, and stack nothing on top. The corners are the weak point, so pad both ends before it leaves the store.
