Does anyone still use the original spring covered by a single piece of cloth RV mattress? Some of the worst things on the planet ever conceived. Those things are just too hard and not comfortable for my bad back. I’ve got a SleepNumber bed at the house and the cost of putting one of those in my 5th wheel was prohibitive. I did a bit of researching on line and found this site:

As my 5th wheel has a full size queen and not the camper queen (which is a scosh shorter) I got their 3 series queen mattress ($499 (shipped if I remember right)). After putting it in the trailer I then topped it with a memory foam topper from Sam's and I now sleep in comfort. Heck, I actually like this bed better than my high-dollar SleepNumber in the house. Adding this mattress required cutting some holes with a hole saw in the plywood foundation that the mattress sits on but that was no major.
If you do have a camper queen in your rig, a full size (double) bed is almost the same size and will fit nicely. In fact, in my old 5th wheel we had a camper queen that we immediately took out and used our guest bed on trips which was a pillow top double.
Having this bed in my trailer makes for a much more enjoyable trip. Remember, you spend about a 3rd of your life in bed. Why not make it comfortable?
I am in no way affiliated with either SleepNumber or the Sleep Better Store. Just sharing good products.
Happy camping and sleeping.
