All of our teak products are produced from the highest quality plantation grade teak and they will last for years giving many years of reliable service. Although it weathers very well, natural teak does acquire a silver patina with age and can also go green when very aged. None of these cosmetic changes affect the durability of the wood itself and teak is extremely hardwearing and long lasting. It's a surprisingly low maintenance choice for patio furniture. Rarely does it require cleaning and you can choose to let it grow silver with the elements.
