Spring Mattresses vs. Foam Mattresses: Which Offers Better Temperature Regulation?

by:JLH Mattress     2024-04-02


Have you ever woken up in the middle of the night feeling uncomfortably warm or finding yourself drenched in sweat? Temperature regulation plays a crucial role in ensuring a good night's sleep. When it comes to choosing a mattress, finding one that helps regulate your body temperature is essential for a restful slumber. Spring mattresses and foam mattresses are two popular options, each with their own set of benefits and drawbacks. In this article, we will delve into the world of mattress temperature regulation and explore whether spring mattresses or foam mattresses are better at keeping you cool and comfortable throughout the night.

Understanding the Mechanics of Temperature Regulation in Mattresses

Before we dive into the comparisons, it's important to understand how mattresses contribute to temperature regulation. The ability of a mattress to absorb, retain, and dissipate heat plays a vital role in determining its temperature regulation properties.

Spring Mattresses:

Spring mattresses are constructed with a network of metal springs or coils beneath layers of padding and fabric. This design allows for ample airflow within the mattress, enabling better breathability and heat dissipation. The space between the springs promotes ventilation and ensures that heat doesn't get trapped in the mattress.

Foam Mattresses:

On the other hand, foam mattresses are typically made of layers of different foam materials, such as memory foam or latex. These foam layers contour to your body shape, providing pressure relief and excellent support. However, the closed-cell structure of foam can limit airflow and potentially trap heat, causing discomfort during sleep.

Now that we have a basic understanding of how these mattresses work, let's explore the temperature regulation capabilities of spring mattresses and foam mattresses in more detail.

Comparing Temperature Regulation in Spring Mattresses

Spring mattresses are often praised for their ability to stay cool, making them a popular choice for hot sleepers. Here are some key factors that contribute to their temperature-regulating properties:

1. Coil Design and Wire Gauge:

The type of coil design and wire gauge used in spring mattresses can impact their breathability and heat dissipation. Mattresses with open coil systems, also known as Bonnell coils, feature interconnected springs, allowing for increased airflow. Additionally, a lower wire gauge indicates thicker coils, which promote more ventilation and prevent heat retention.

2. Encased Coils:

Some spring mattresses incorporate encased coils, individually wrapped in fabric pockets. This design not only provides targeted support but also enhances airflow. The encasement allows air to circulate more freely through the mattress, preventing heat buildup.

3. Topped with Cool Sleep Technology:

To enhance temperature regulation further, many spring mattresses come with cooling features. Gel-infused foam or gel-infused memory foam layers are often added to the top comfort layers of the mattress. These materials have cooling properties and help dissipate heat away from the body.

4. Natural Fiber Covers:

Spring mattresses often boast breathable covers made of natural fibers such as cotton or bamboo. These materials have moisture-wicking properties, drawing sweat away from the body and aiding in evaporation, thereby keeping you cool and dry.

Comparing Temperature Regulation in Foam Mattresses

While foam mattresses are known for their exceptional support and pressure relief, temperature regulation can be a concern for some individuals. However, advancements in foam technology have led to the introduction of cooling features in foam mattresses. Let's take a closer look:

1. Open-Cell Structure:

Traditional closed-cell foam mattresses tend to trap heat due to the limited airflow within the foam layers. However, many modern foam mattresses employ open-cell structures. These open-cell foams allow air to flow more freely through the mattress, preventing heat buildup and promoting better temperature regulation.

2. Gel-Infused Foam:

Gel-infused memory foam has gained popularity in recent years due to its cooling properties. The gel beads infused within the foam help dissipate heat and regulate temperature. This innovative technology allows for a cooler sleeping experience on a foam mattress.

3. Copper-Infused Foam:

Foam mattresses infused with copper particles have also emerged as a solution for heat retention. Copper has excellent heat conductivity properties, effectively drawing heat away from the body and promoting a cooler sleep environment.

4. Ventilation Layers:

Some foam mattresses incorporate ventilation layers, often made of convoluted foam or special perforations in the foam layers. These layers improve airflow, preventing heat from getting trapped within the mattress. By allowing for better breathability, these mattresses promote a cooler and more comfortable sleep.

Which Mattress Offers Better Temperature Regulation?

When it comes to determining which mattress offers superior temperature regulation, it ultimately depends on individual preferences and requirements. Both spring mattresses and foam mattresses have their own advantages in terms of temperature control.

Spring mattresses excel in promoting airflow due to their coil design, wire gauge, and encased coils. The open structure allows air to circulate freely, preventing heat from accumulating in the mattress. Additionally, the integration of cooling technologies, such as gel-infused foam and natural fiber covers, further enhances their breathability and cooling properties.

On the other hand, foam mattresses have made significant advancements in temperature regulation, thanks to innovations like open-cell structures, gel-infused foam, and copper-infused foam. These features work together to dissipate heat and create a more comfortable sleeping surface.


Choosing the right mattress for optimal temperature regulation is crucial to getting a good night's sleep. Spring mattresses and foam mattresses both offer unique advantages when it comes to keeping you cool and comfortable throughout the night. While spring mattresses excel in promoting airflow and breathability, foam mattresses have embraced innovative cooling technologies to address heat retention concerns.

When making your decision, consider your personal preferences, sleep habits, and body temperature. Testing out different mattresses, understanding their construction, and researching customer reviews can also help you make an informed choice. Remember, a well-regulated mattress can significantly contribute to the overall quality of your sleep, ensuring you wake up feeling refreshed and rejuvenated each morning.
