Rubber rug pads

As beautiful as hard wood floors are, sometimes it takes a beautiful rug or carpet to complement the decor and bring out the character of a room. If this is the case in your home, consider using a rubber rug pad underneath the rug to keep it from slipping and sliding. This is especially important if you have children or large pets who like to run through the house.
