Does A Cooling Mattress Make You Cold?

No! A cooling mattress doesn’t make you cold but can cool your body. In other words, it can lower your body temperature when you’re feeling too hot without making you feel cold. This is because a cooling mattress is designed with thermo-regulating materials that draw excess heat from hot sleepers.

Cooling Mattress Make You Cold

Let’s dig deeper.

Why a Cooling Mattress Can’t Make You Cold

Cooling mattresses are designed with materials that only dissipate enough heat to help you fall asleep then the effect wears off after a while.

More concisely, here’s how some of the materials in a cooling mattress work to keep you cool without getting cold:

Phase Changing Materials

Phase-changing materials (PCM) is a substance spun in a cooling mattress’s fabric to absorb excess heat when temperatures are high and then releases the heat when it gets cold.

To put it into context, the PCM in a cooling mattress will help to keep you cool when you feel hot. Then when you start feeling cold, it will release the stored heat to keep you warm.

Gel Memory Foam

Gel memory foam is engineered with thermo gel that changes from solid to liquid when your body temperature rises. This helps to draw away excess heat from hot sleepers to facilitate sleep. However, once you’re cool, the gel will revert to its solid foam, and you will probably feel hot again.

Try a hybrid or innerspring mattress with gel memory foam for the best cooling results.

What is the Ideal Temperature if you’re Sleeping on a Cooling Mattress?

It depends; most cooling mattresses are designed with thermo-regulating materials that respond to body temperature. If your body is at its average temperature of 98.6 °F and your room temperature is between 66 °F to 70 °F, your cooling mattress will be at the same temperature as your body.

However, if you’re too hot to sleep, the cooling mattress’s temperature will drop but only to the extent that makes you comfortable. Once you’ve fallen asleep, most cooling mattress cooling effects wear out, and you might start feeling hot again.

Things That Affect a Cooling Mattress’ Ability to Regulate Temperature

Mattress Structure

If a cooling mattress is engineered with an open cell structure, it provides better airflow, which helps to dissipate excess heat compared to dense traditional memory foam.

In addition, some manufacturers use the honeycomb design at the core to ensure that the cooling mattress doesn’t facilitate heat retention.

Its Core Layer  

For the best cooling experience, most manufacturers incorporate pocket coils and innerspring. This is because the springs increase airflow, which helps to draw excess heat from the body.


A cooling mattress can keep you cool when you sleep, but it won’t make you feel cold — that’s a big difference. Cooling mattresses regulate your temperature as you sleep and provide comfort and pain relief.
