How do cast iron outdoor chairs compare to wrought iron in terms of thermal mass?

When choosing outdoor furniture, thermal mass is an important factor, especially for chairs exposed to sunlight or varying temperatures. Cast iron and wrought iron are both popular materials, but they differ in how they handle heat.

Cast iron outdoor chairs have a higher thermal mass than wrought iron, meaning they absorb and retain heat more effectively. This makes them slower to warm up in the sun but also slower to cool down, providing a stable seating temperature. However, this can make them uncomfortably hot in direct sunlight for extended periods.

Wrought iron chairs, while still durable, have a slightly lower thermal mass. They heat up and cool down faster, making them more adaptable to changing weather conditions. This can be an advantage in climates with fluctuating temperatures.

Both materials are sturdy and long-lasting, but if heat retention is a priority, cast iron may be preferable for cooler environments, while wrought iron could be better for hotter climates. Consider your local weather and intended use when deciding between the two.
