Sofabed question

You could use something as simple and inexpensive as an egg crate foam, then make up the bed or as fancy as a Memory Foam type. Is the sofa you have a jack-knife type or a fold out? Our jack-knife in our HTT was about the least comfy you could find and thankful we only used it turtling once or twice. Our new TT has a sofa bed with an air mattress that is very comfortable. Don't know if you normally use a mattress pad under the sheets, but that will also help to soften some of the bumpy spots. Unless you always have guests or for longer trips, I would not get too pricey with this...remember, it's camping, not a 5-Star hotel.
