Every aspect of this outdoor sofa was designed with durability as well as style in mind. The frame is made of teak, a hardwood prized for its resistance to moisture (and termites!), that's been given a special finish to expedite the aging process that results in its distinctive silvery hue. The back and the seat support are intricately woven with all-weather rope, and the removable seat cushions are covered in weather-resistant performance fabric.
