To remove a dent in the leather seat of a car, soak a towel in hot water then wring most of the water out. Fold the towel into quarters and set it down over the dent. Place a heavy object on top and leave for 2 hours. After 2 hours repeat this process another 3 times. Rub a leather conditioner into the seat and leave untouched for 24 hours. After this time, the dent should be gone.
