We are purchasing a 2021 Salem Hemisphere with a tri-fold sofa. We are wondering what some of done for a mattress for this. How can we use sheets also. Our previous couch from 2011 used an air mattress.
It's not a matter of what size sheets. There is nothing really to wrap the sheets around. I looked at a thinner air mattress on Amazon to try. A full thickness air mattress would put the bed too high to get in.
We always use the sheets we have with no issues (usually fitted) or you could get sheets that are not fitted. Not sure what you mean by nothing to wrap the sheets around.
But if the sofa mattress is not adequate you can get up to a 4" foam topper.
The DW learned how to make beds in a hospital (nursing school in the 1970s) and on the farm and can do it easily.
We have had about 6 campers over 40 years do not sweat about the little things.
