jayco bunk mattress replacement???

Our "Queen" sized bed is like many other TT beds, the size is approximate. :)

We tried a thick sleeping bag as a cushion but finally ended up with a blue egg carton shaped foam pad from Camping World. It is about 4 inches thick. We did have to trim it to fit our bed size.

I am sure there are similar product available but we are happy with ours.

Good Luck

That's what we did with ours. But we also put in the adjustable frames. We bought the full queen size memory foam mattress, and cut it in half. So I can elevate my head and feet and the wife doesn't have to. They don't sell the split mattress anymore.

Memory foam. Get a standard size and cut it. Google DIY foam cutter

I would recommend getting a foam mattresses that you can cut down to size. Buying a custom made mattress can get expensive.

The problem you are going to have is that it isn't a standard twin size (39x74). So you will have to go with a custom or RV size which limits your selection.

You could try some of the mattresses on Amazon that come in the 30x74 size:

Amazon - 30x74 mattresses

Some are inexpensive and just about any foam mattress will be an improvement over the paper thin ones that come standard.

Look at the memory foam mattresses on Walmart.com.
