I know several people that have replaced stuff in RV's with the Lay-Z-Boy recliners. Great choice. They are readily available at Lay-Z-Boy stores, and possibly some other furniture emporiums. I know there are Lay-Z-Boy stores in Canada I have seen them in Toronto.
Take your tape measure with you to make sure you get one that fits. The backs on most of them come off to make getting them through a narrow door easier. They also make some that can sit right against a wall and still recline.
