Teak

Teak has well known qualities that make it superior to other woods for outdoor furniture applications. Because of its high oil content it is resistant to rotting, bug infestation, and the effects of wind, rain, sun, and snow. If left untreated, teak weathers naturally to a beautiful silver gray color. Some surface roughness may develop, especially at the end grain, but over a period of about one year, the natural weathering process will stabilize. Small surface cracks may appear but in no way affect the structural integrity of the furniture.
