Hi LOGANROSS,
There is more about the many variables that can affect the sleeping temperature of a mattress or sleeping system in post #2 here.
While it’s not possible to quantify the sleeping temperature of a mattress for any particular person with any real accuracy because there are so many variables involved including the type of mattress protector and the sheets and bedding that you use (which in many cases can have just as significant an effect on temperature as the type of foam in a mattress), the temperature and humidity of your room, the firmness of the mattress, and on where you are in the “oven to iceberg” range … the layers and materials that are closer to your skin will have a much larger effect on sleeping temperature than the foundation under the mattress (which is unlikely to have a noticeable effect on sleeping temperature).
Your mattress uses Talalay latex which is the most breathable of all the foam materials (latex foam, memory foam, and polyfoam) and the top layer is also convoluted which will also increase the airflow and you also have a wool quilted cotton cover which is also among the most temperature and humidity regulating covers (wool in particular is a great temperature regulator) so it would be very unlikely that you would have any issues with temperature regulation on your mattress.
