Hearth rugs are made from flame-retardant materials. They protect your floor from sparks, that might catch your flooring on fire, preventing damage. Most hearth rugs are made with fire-resistant fiberglass.
When it comes to style, hearth rugs come in a variety of colors and patterns. Just like any other rug you'd choose for your home. Most rugs have a straight edge, so that you can place it right next to your fireplace. Half round or rectangular rugs are the most common shapes, however there are some other options available.
