We have a hybrid trailer, and the mattresses in there leave a lot to be desired, not nearly as nice as the ones in our old PUP. My idea is to buy one piece of memory foam, and make a new mattress for one bunk end, and doubling up the stock mattresses on the other bed. So, I have no clue on what foam to choose. It goes by thickness, and weights,and I get lost.Basically, what Im asking, is a 4 inch thick one that's advertised as 5.5 firmness , is that soft, to hard, to thick, etc??? and what thickness/weight would you use? and, does the memory foam cut easily, as I will have to custom cut my sized pieces to make the mattress fold in half for storage in the bunk end when closed?
Thanks in advance for any and all help you can offer, and tips on going about this task.
