Ways to Cool Down Your Memory Foam Mattress

Written by milton kazmeyer | 13/05/2017

Memory foam mattresses have become a popular sleeping choice for many, and the comfort and cradling sensation these beds provide can result in a very restful night's sleep. Unfortunately, the density of memory foam can lead to body heat build-up, making it hard for those who need to sleep cool to sleep well. Luckily, there are a few things you can do to keep your mattress cool and comfortable.

Ambient Temperature

One way to cool down your memory foam mattress is simply to cool down the bedroom where you sleep. A colder temperature will result in a longer period before your body heat warms the mattress to an uncomfortable level. Even a fan can help cool things off, as air moving across the mattress surface will help disperse radiant heat.

Elevation

While memory foam mattresses can simply be placed on a flat surface and many models do not require frames, this can lead to heat build-up. Another way to cool off your memory foam mattress is to allow plenty of airflow around and under your bed. Raising your bed using a frame or foundation will allow heat to radiate from the underside of the mattress, reducing heat build-up considerably. It is important, however, to ensure that your memory foam mattress remains suitably supported, as some models are not as rigid as traditional mattresses.

Mattress Pad

Another option for a cooler night's sleep is to use a mattress pad. This extra layer of insulation between your body and the foam of the mattress will reduce heat transfer, and should increase your comfort level. Eggshell foam mattress toppers can also cool you off by introducing air pockets between you and the mattress surface; however, these can tend to break down and flatten out over time.

Cold Extremes

Unfortunately, cooling off your mattress too much can result in another type of uncomfortable sleeping experience. As memory foam cools, it loses its pliability, reducing its ability to mould around your body as well as the speed at which it returns to its original shape. This can lead to sleeping in a "hole," a body-shaped depression in the mattress that remains depressed for a long period instead of bouncing back. This effect is not permanent, however, and memory foam will return to normal upon reaching room temperature.

Considerations

The heat-retaining capacity of memory foam is simply a factor that should be taken into account when shopping for a new mattress. While you can do a few things to mitigate this effect, as a rule, memory foam mattresses will always tend to sleep warmer than their traditional spring counterparts.
