Heat Sensitive Visco Elastic Foam Mattresses

Heat sensitivity is normally looked upon as one of the pluses of a memory foam mattress. However oversensitivity to temperature is not necessarily a good thing in visco elastic foam materials. Sensitive foams also respond to ambient temperature as well as body temperature so if the room is too cold then this type of foam becomes stiff. When you go to lie down on it in the dead of winter it will have a hard feel to it before it begins to react to your body temperature and start to become more pliable and soft. Conversely when the room is warm the mattress becomes soft and tends to feel like it is lacking in support. When shopping for a visco elastic memory foam mattress try to find a memory foam that does not have this kind of reaction to temperature fluctuations and you will sleep more soundly.
