Furniture coasters are small pads or discs placed under the legs of furniture to protect floors from scratches and dents. They are commonly made from materials like rubber, felt, or plastic, and come in various shapes and sizes to fit different furniture types. By distributing the weight of the furniture, coasters help prevent damage to hardwood, tile, or carpeted surfaces. In addition to protecting floors, furniture coasters can also make it easier to move heavy items. They reduce friction, allowing chairs, tables, and other pieces to glide smoothly across the floor. This feature is especially useful in homes with hardwood floors or delicate carpets.
