You have a choice of topping material: vinyl or canvas. The OEM original topping material depended on the model of Sebring. Vinyl is less expensive and a great material and Cloth has a richer look and better acoustical properties. Twillfast Cloth was the original material used on the LXi, Limited and other models. It is a premium quality topping with cloth inner lining. Sailcloth Vinyl was the original material used on the JX models. Both materials are very durable and will last many years with proper care. The glass window bond on both materials has a lifetime warranty against failure.
