Hi Polyphasicsleep,
I’m not quite clear what you are asking me but I think highly about Rick and the mattresses he designs for Relief Mart. You can see more of my thoughts about them in post #9 here.
Not surprisingly … I also agree with the information he provides in the video you linked that higher airflow can improve the temperature and moisture regulation in a mattress. There is more about the many variables that can affect sleeping temperature in post #2 here and there is also more about cooling down memory foam in post #6 here.
Natural fibers such as wool and silk are certainly effective for temperature regulation as well.
