What is the average lifespan of a cast iron outdoor sofa?

The average lifespan of a cast iron outdoor sofa typically ranges between 15 to 30 years, depending on factors like climate, maintenance, and usage. Cast iron is highly durable and resistant to wear, but exposure to harsh weather conditions—such as rain, humidity, or extreme temperatures—can accelerate rust and corrosion if not properly cared for.

To maximize longevity, regular maintenance is essential. Applying protective coatings (like paint or sealant), cleaning off dirt and moisture, and using covers during off-seasons can significantly extend its life. Additionally, placing the sofa in a covered or shaded area reduces direct exposure to the elements.

While cast iron outdoor sofas are heavier and more expensive than other materials, their sturdiness and timeless design make them a worthwhile investment for long-term outdoor comfort. With proper care, they can remain functional and stylish for decades.
