sandy, those seats came from west marine. they're
sold as "event seats" and fold in half with backpack straps to carry to the event. that's a feature i never use however. installation was very easy. remove the cushions from the dinette seats and place the new seats on top of the box bases that are in my
casita spirit deluxe. they are very comfortable and a huge improvement over those original back breakers. they're kinda pricey but my back sure appreciates the change.
