Very nice fit for the rear seats, the Big likes to sit on it. However, there may be problems in the front seat, if it is slim cut and run with large bolsters for lateral support. Then can the booster seat not quite push the backrest and you can sit on a small increase, which is meant for the polymer / buttocks area. This is quite painful. If one knows that it is used only on a standard rear seats, but the part is recommended.
