When selecting wood for sculptures that will serve as public seating or furniture, durability, weather resistance, and aesthetic appeal are key considerations. Hardwoods like teak, oak, and black locust are excellent choices due to their natural resistance to rot, insects, and wear. Teak, known for its high oil content, withstands outdoor conditions effortlessly, while oak offers strength and a timeless grain pattern. For a more sustainable option, black locust is incredibly hardy and requires minimal maintenance. Softer woods like cedar or redwood can also be used but may need additional treatments for longevity. Always prioritize woods with tight grain and density to ensure the sculpture remains functional and visually striking for years.
