We have the RVsuper Bag and are very happy with it. We have a single bed 2552 so I cannot speak to how it would work in a 2350. In our rig it makes it so easy to just fold and roll up the bed, tuck it under the wardrobe and then the bed with the cushions works perfectly as a couch or day bed. We used it all summer with no issues. It has two sides of different thicknesses. In summer you put the thick side down, in winter the thick side goes up.
