Although we have a different rig (Forest River 43' 5th wheel), we just replaced our really cheap OEM recliners + sleeper sofa with a La-z-Boy combination (2 recliners and a double seat sofa).
After three years of full-time use, the OEM stuff was finished (lumpy, uncomfortable, springs were sprung (I am the heaviest person @ 160#), and starting to fall apart (the furniture - not me!). The La-z-Boy recliners/sofa are of a much higher quality construction and have a much more robust leather composite material (obviously not cheap dollar wise). However we are full time RV travelers, and wanted something that will last a long time.
The La-Z-boy units have easily removable backs that made it real easy to load through the rig's doorway (28" door).
There are obviously many manufactures/suppliers out there with a large range of price tags. It can be a challenge tho' in finding a set-up that will fit size-wise.
