Fir and pine form the frame of this wooden porch swing, a timber pairing that naturally resists rot, decay, and insect damage without chemical treatment. The 52-in seat runs 23.5-in deep behind a curved backrest that follows the spine instead of sitting flat, giving a rustic profile with real lower back support. Rated to 440 lb, the bench seats two adults with room to spare. The wood arrives sanded smooth in a natural finish that can be left bare to weather gray or sealed to hold its tone. The swing ships in two boxes.
