"Natural" or "synthetic" latex would be the actual distinction if there was one. One rubber substance is derived from plant or tree sources and the other from petroleum type products There is no true "organic latex" because no certification of latex exists as to 100% organic components. Recognized Boards certify "organic" and none certify latex as of yet. As long as "latex" is okay for the enclosure the labeling is meaningless. It is false advertising.
