STURDY, Modern Adirondack Chair, Redesigned for maximum comfort! About Eucalyptus: Eucalyptus Wood is a smarter, less expensive, and ecologically friendly alternative to Teak Patio Furniture, and it is growing quickly in popularity. Like Teak, Eucalyptus is a durable and beautiful tropical hardwood that is naturally resistant to insect infestation and damage caused by moisture. Unlike Teak, Eucalyptus trees are fast growing and more readily available; as a result, products made from Eucalyptus wood are less expensive.
