We may have considered replacing our mattress, it is a bit firm, but in our 2016 2106DS the bed is a fold-up bed not the current Murphy bed. Our mattress is hinged and folds in half on top of itself, it would be a custom replacement. We added this mattress topper
to try and soften it up a little. It works for now but could be approved upon.
