What are the load capacity differences between aluminum and cast iron outdoor armchairs?

When selecting outdoor armchairs, understanding the load capacity differences between aluminum and cast iron is crucial for durability and safety. Aluminum armchairs are lightweight, corrosion-resistant, and typically support 250-300 pounds, making them ideal for casual use. Cast iron armchairs, on the other hand, are heavier and more robust, often holding 400-500 pounds, but require maintenance to prevent rust. While aluminum suits modern, portable setups, cast iron excels in stability and longevity for permanent outdoor spaces. Consider your needs—weight, weather resistance, and strength—to choose the best option for your patio or garden.
