Using a heated mattress pad, blanket, etc. with memory foam:

Your body heat is the right temperature to soften the memory foam to a comfortable position. Adding the use of an electric blanket, mattress pad, etc. will further soften the memory foam which could alter its performance. Therefore, we do not recommend the use of any additional heat source on a memory foam product as it may affect the performance of the memory foam which may result in voiding your warranty.
