What are the best wood types for outdoor sofa frames in earthquake-prone zones?

When selecting wood for outdoor sofa frames in earthquake-prone zones, durability and flexibility are key. The best options include teak, known for its natural resistance to weathering and pests; cedar, which offers lightweight strength and rot resistance; and redwood, prized for its stability and longevity. These woods can withstand seismic activity while maintaining structural integrity. Additionally, treated pine is a cost-effective choice when properly sealed for outdoor use. Always ensure the wood is certified for seismic resilience and pair it with sturdy joinery techniques for optimal safety.
