It is all going to depend on how much you want to spend. Furniture is usually a personal thing, how comfortable is it to you. Then you must meet size requirements for your trailer. I would start at a local furniture store and go from there. La-Z-Boy and Ashley usually will have something that will fit but then there are the other concerns. The OE manufacturers like Thomas Payne or Praxis would most likely be the last place I would look.
As Jetzen said, try local retailers, watch measurements closely, as things get close very quickly. The places in and around Elkhart IN sell new RV furniture that can be better quality than supplied by the manufacturer, so if your are anywhere close I would start there.
