I was at a local RV show this weekend and saw a Winnebago Class A with an electric reclining sofa the lays completely flat and it had a trundle foot rest that slides out and pops up. They call it their "rest easy sofa". Here is a link to a version of it.
starting at 10.21. With both laid flat it would make a reasonable bed. It is exactly what my wife and I have been looking for to replace our uncomfortable sofa. I took a pic of a tag on the sofa, but that didn't lead anywhere. Anyone familiar with this style sofa and know where you can get it aftermarket?
