What is R-Value?
R-Value is a measure of thermal resistance. It measures a mattress's ability to retain or prevent heat from escaping from a warm body (the human body) to a cold floor.
The higher the R-Value, the better the insulation of the mattress.
You should know that R-Values are additive; this means that you can use 2 mattresses and add their R-Values.
