There are a number of benefits to using wrought iron for furniture legs. Wrought iron is particularly good for outdoor furniture due to its durability, easy cleaning and weather-resistant properties.
While iron is a strong and sturdy material, it is also highly customizable. It can be bent, twisted and formed into many different shapes and designs. It can also be finished in the owner's choice of colors and styles.
Wrought iron is a fairly heavy metal. This can be a benefit or a disadvantage depending on its use. Iron-legged furniture cannot be easily blown over even by strong winds, but it can also be hard to move around.
