The Traditions 2-Piece Chat set includes a Durastone LP gas fire pit and crescent-shaped sofa specially crafted for use all year long. Both pieces feature durable all-weather construction and aluminum framework that is naturally rust-resistant and built to last year after year. The sofa?s curved shape offers more seating for guests while taking up less space which is ideal for both large and smaller spaces including corner placement. Plush all-weather cushions are securely bound to the sofa?s frame through Velcro ties and are treated to resist moisture staining and UV harm. The 40 in. square fire pit features a Durastone table top specially sealed to resist moisture penetration as well as other weathering effects. Its center burner holds colorful lava rocks (provided) and flames that burn quietly as you entertain guests. The base of the fire pit features a hidden chamber that holds a 20 lb. LP gas tank (not provided) and a control knob that allows you to adjust the heat output to your preference. Built to last this set will provide an intimate conversation area that can be enjoyed any time of the year.
