Q : What's the difference between the Memory Foam Zone 7 and Memory Foam Zone 3. I've heard that they can be too warm, especially for those who are prone to over-heating at night! I was thinking of purchasing the Zone 3 but am concerned about it retaining body heat?
A : The main reason that foam mattresses can get warm is that they are designed to put your body as close to the foam as possible so you get the best levels of support. Foam is a good insulator, which means the sleep experience can feel a little warmer as it absorbs your body heat without dispersing it.The 7 zone mattress has more posture zones than the 3 zone mattress.
