They're perfect for relaxing with family and friends. A perfectly valid recommendation for caring for teak is to do nothing, it will not split or age or warp and nothing that preserves the appearance of teak is necessary to protect it. Although it weathers very well, natural teak does acquire a silver patina with age and can also go green when very aged. Wood is a natural choice that is a welcome and warming touch. Wood design works beautifully as a solo or matching piece.
