Do Memory Foam Mattresses Keep You Cool?

Memory foam mattresses can keep you cool, but it depends on the type of memory foam and the cooling technologies used. 

Traditional memory foam is known for retaining heat, but modern advancements have introduced various solutions to this problem. 

Technologies such as gel infusions, open-cell structures, and phase-change materials have been developed to enhance airflow and dissipate heat, making today's memory foam mattresses much cooler than older versions.

How Memory Foam Mattresses Work

Understanding Memory Foam

Memory foam is made from viscoelastic polyurethane, which responds to heat and pressure, allowing it to contour to your body shape. 

This unique property provides excellent support and pressure relief. 

However, this same characteristic can lead to heat retention, as the material traps body heat.

Heat Retention in Traditional Memory Foam

Traditional memory foam mattresses can retain heat because the dense material restricts airflow. 

As your body heats the mattress, the foam softens and conforms to your shape, trapping heat and causing discomfort. 

This issue has led to the development of various cooling technologies to mitigate heat retention.

Cooling Technologies in Memory Foam Mattresses

Gel-Infused Memory Foam

Gel-infused memory foam incorporates gel beads or swirls into the foam. 

These gels help to dissipate heat more effectively than traditional memory foam. Gel-infused mattresses provide a cooler sleeping surface by absorbing and dispersing body heat.

Open-Cell Memory Foam

Open-cell memory foam has a less dense structure with interconnected pockets of air, which allows for better airflow. 

This increased ventilation helps to carry heat away from the body, making the mattress feel cooler throughout the night.

Phase-Change Materials

Some memory foam mattresses contain phase-change materials (PCMs) that regulate temperature. 

PCMs absorb excess heat when you are too warm and release it when you are too cool, maintaining a comfortable sleeping temperature.

Breathable Mattress Covers

Breathable mattress covers are designed to enhance the cooling properties of memory foam mattresses. 

These covers use fabrics that promote airflow and wick away moisture, further helping to keep you cool and dry during sleep.

Factors to Consider When Choosing a Cooling Memory Foam Mattress

Firmness and Support

The firmness of a mattress can affect its cooling properties. 

Firmer mattresses tend to have less sinkage, which can help with airflow around your body. When choosing the firmness level, consider your comfort preferences and support needs.

Mattress Thickness

Thicker mattresses can retain more heat than thinner ones. 

A thinner profile can enhance cooling, but it's important to balance this with the level of support you need.

Sleep Position

Your sleep position can influence how cool you feel on a memory foam mattress. 

Side sleepers might benefit from softer mattresses that contour more, while back and stomach sleepers may prefer firmer options to maintain spinal alignment and reduce heat retention.

Room Temperature and Bedding

External factors such as room temperature and bedding choices also impact how cool you feel on a memory foam mattress. 

To enhance the cooling effects of your mattress, opt for breathable sheets and maintain a cooler room temperature.

Benefits of Cooling Memory Foam Mattresses

Cooling memory foam mattresses offer several benefits beyond temperature regulation. 

They provide excellent pressure relief, reducing aches and pains. 

These mattresses also support proper spinal alignment, improving sleep quality. By staying cooler, you can enjoy uninterrupted sleep and wake up refreshed and energized.


Memory foam mattresses with advanced cooling technologies can help keep you cool at night. 

By understanding the different cooling technologies and considering factors such as firmness, thickness, and sleep position, you can choose the right cooling memory foam mattress. 

Investing in a cooling memory foam mattress can improve sleep quality and overall well-being, providing you with reassurance and confidence in your potential purchase.


How long does a memory foam mattress last?

Memory foam mattresses typically last 7-10 years, depending on the quality and care.

Are cooling memory foam mattresses more expensive?

Due to the advanced technologies, cooling memory foam mattresses can be slightly more expensive than traditional ones. 

However, they offer better comfort and sleep quality, making them a worthwhile investment for many sleepers.

Can I use a mattress topper to make my current mattress cooler?

Yes, a cooling mattress topper can enhance the cooling properties of your existing mattress.

How do I maintain my cooling memory foam mattress?

Regularly rotating your mattress and using a breathable mattress cover can help maintain its cooling properties and extend its lifespan. 

Additionally, keeping the room temperature moderate and using breathable bedding can further enhance the cooling effect of your memory foam mattress.

Are cooling memory foam pillows available?

Cooling memory foam pillows can complement your cooling mattress for a complete sleep solution.
