We own a 2015 Heartland Cyclone 4000 toy hauler. All furniture needs replaced. I have had zero issues with regular couches/recliners etc. But we have the toy hauler with the seating on each side that folds up if need be. Does anyone know the correct name of the seating? It is 60 inch seat from support to support. Just want to replace both seating areas, as mechanism works fine. PLEASE HELP!
