bed comfort/memory foam
we have a 1969 globetrotter which has the "full" size bed conversion in the back. the previous owners updated the foam so it is about 5 inches thick, 3 inches of which is regular foam with 2 inches of memory foam. we have slept in about 5 nights total now, and I wouldnt say its uncomfortable, but we are used to our costco memory foam which feels like a cloud and we have sore back muscles after a few nights sleep in the airstream. My idea was to order a full size memory foam and lay out the current cushions, trace, and cut the memory foam to size. but i want to know what memory foam you all would recommend. we like a blend of soft and firm! we want it to last, not something that would flatten out like a pancake after a year or so.
