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.
