Do you ever wake up in the morning feeling hot and sweaty? Are you tossing and turning all night because you can't get comfortable? If so, your mattress might be to blame. Believe it or not, your mattress can significantly affect how cool or warm you sleep at night.

If you're interested in finding a mattress that offers you the best chance of sleeping cool and comfortably, you may want to consider a cooling mattress. But do cooling mattresses work? In this article, we'll look at the effectiveness of cooling technology in beds and discuss whether they are right for you.

What Is a Cooling Mattress?

A cooling mattress regulates temperature, keeping the sleeper cool and comfortable throughout the night. There are a variety of cooling mattresses on the market, each with its unique set of features to help regulate the mattress temperature and dissipate the extra heat from the sleeper and the mattress surface. No matter which type of cooling mattress you choose, it's crucial to find one that fits your needs and sleeping habits.

Different Types of Cooling Mattresses

Each mattress manufacturer incorporates cooling technology into their mattresses to offer a more comfortable and cooler sleeping experience. While there are many different types of cooling technology available on the market, they all work to achieve the same goal: to keep you cool and comfortable while you sleep.

Specialized Mattress Core Structure

Many manufacturers have invented different mattress core structure shapes to promote airflow and heat dissipation. Although the core mainly functions as the main support and stabilizer for the mattress, it also plays an essential role in cooling. Some manufacturers have designed their mattresses with a hole-punch design (also known as open-cell foam construction). This design creates more airflow and allows heat to escape more easily, preventing the sleeper from feeling hot and sweaty at night.

Mattresses with a specialized core structure not only offer better support and stability, but also tend to be more durable and long-lasting.

In addition to the open-cell core structure, manufacturers may use a honeycomb design or the egg crate design mattress core to create even more surface area for air to circulate. This design is especially effective for cooling because it allows air to circulate freely and evenly throughout the mattress.

Advantages to Specialized Core Structure Technology

One advantage of cooling mattresses with a specialized core structure is that they offer better support and stability. The honeycomb and egg crate designs provide additional support by distributing weight evenly so the sleeper doesn't sink into the mattress and create heat pockets. These mattresses are also more durable and longer lasting than traditional mattresses because they don't sag as easily.

Another advantage of cooling mattresses with a specialized core structure is that they offer better temperature regulation. The open-cell foam construction and honeycomb design allow air to circulate more freely, which helps to dissipate heat away from the sleeper. These mattresses are also more breathable, keeping the sleeper cool and comfortable.

Disadvantages to Specialized Core Structure Technology

The downside to cooling mattresses with a specialized core structure is that they are more expensive than traditional spring mattresses. Additionally, some customers find the mattress less comfortable because the open-cell construction can make the mattress feel firmer.

Mattress Brands That Use Core Structure Technology

Many memory foam mattress brands use cooling technology in their mattresses. The most highly recommended brands include Nectar, Purple, Casper, Bear, Leesa, and Cocoon by Sealy.

Mattress Cooling Pads

Many foam mattress manufacturers incorporate cooling pads as their top layer to maximize heat absorption and dissipation. The most common type of cooling pad is made of cool memory foam, a kind of memory foam infused with cooling gel, which helps to regulate temperature and keep the sleeper cool and comfortable.

Some other types of cooling pads use phase change material, which absorbs and stores heat until it reaches a certain temperature, at which point it releases the heat and begins to cool down again. Whatever the type, mattress cooling pads can provide significant relief from overheating during sleep.

Advantages to Mattress Cooling Pads

Mattress cooling pads are a great way to keep your bed cool and comfortable during the hot summer. There are several different types of cooling pads on the market, but they all work by providing a layer of insulation between your body and the mattress, preventing heat from being absorbed by the bed. As a result, you will stay cooler and more comfortable while you sleep.

As a bonus, many cooling pads also provide extra support and cushioning, which can be helpful for people with back pain or other medical conditions. Whether you want a way to stay cool during the summer or need extra support for your back, a mattress cooling pad is a great option.

Disadvantages of Mattress Cooling Pads

There are some potential disadvantages to using a mattress cooling pad. One concern is that the cooling effect may be too intense for some people, causing them to wake up feeling cold and uncomfortable. Additionally, mattress cooling pads are prone to damage as the fiber material can be punctured or lose its shape without proper care.

Mattress Brands That Use Mattress Cooling Pad Technology

Most mattress brands have cooling pads as an upgrade to their standard mattress. Nectar, Purple, Casper, and Bear are some of the most popular options.

Temperature Control Mattress

Temperature control mattresses regulate the bed's temperature, keeping the sleeper cool and comfortable throughout the night. These mattresses typically use a cooling system controlled by a thermostat that can be adjusted to the desired temperature. Temperature control mattresses are a good option for those who want to customize the cooling of their mattress and who don't mind paying a bit more for the features.

Advantages to Temperature Control Mattresses

The advantage of temperature control mattresses is that they can be customized to the sleeper's needs and are generally more effective at cooling the entire bed, not just the surface. And instead of resorting to room air conditioning, the cooling system on these mattresses will only use as much energy as needed to maintain the desired temperature, making them more environmentally friendly.

Disadvantages to Temperature Control Mattresses

The disadvantage of temperature control mattresses is that they tend to be more expensive than other cooling mattress options. They also require a power source to operate, so an outlet's availability may limit your bed's position. However, a power strip or extension cord can easily resolve this problem. Additionally, the cooling system requires regular maintenance to keep it running properly.

Mattress Brands That Specialize in Temperature Control Mattresses

Because temperature control mattresses are still quite expensive and a relatively new concept, Eight Sleep is the only current brand specializing in this type of mattress. However, BedJet and Chilisleep have created add-on cooling systems that can be used with any mattress to turn it into a temperature control mattress.

Mattress Core Structure vs. Mattress Cooling Pads

In general, cooling mattress cores are more effective than cooling mattress pads because they regulate temperature at the mattress's core, where heat builds up. As a result, they can better dissipate heat away from the body.

Look for cool gel memory foam mattresses that have cooling mattress cores and cooling pad material to maximize sleep temperature comfort.

However, cooling mattress pads can still be an effective way to cool a mattress. They are typically less expensive than cooling mattress cores and can be easily added to an existing mattress. Additionally, some cooling mattress pads feature innovative technologies that help to improve their performance. For example, some pads are made from materials that reflect heat. As a result, they can provide a significant amount of relief from night sweats and hot flashes.

Ultimately, the best way to cool a mattress will depend on your specific needs and preferences. If you're looking for the most effective solution possible, you may look into mattresses incorporating both cooling technologies. Many cool gel memory foam mattress options have cooling mattress cores and cooling mattress pad material to provide the best of both worlds. Although they can be more expensive, they offer the most comprehensive cooling solution.

Cool Gel Memory Foam Mattress vs. Temperature Control Mattress

Both types of mattresses are designed to regulate body temperature, but they work in different ways. A cool gel memory foam mattress uses special gel-infused memory foam to absorb and distribute body heat. In contrast, a temperature control mattress uses active cooling technology to regulate body temperature. Some models feature a water-cooling system that circulates cool water through the mattress, while others use fans or air pumps to circulate air. Either way, these systems are designed to help keep the sleeper cool and comfortable all night long.

So, which type of mattress is more effective at cooling? It's hard to say definitively, as both types of mattresses have pros and cons. A cool gel memory foam mattress may provide better initial cooling, as the gel cooling pad material helps to dissipate heat quickly. However, a temperature control mattress may be more effective in the long run, as it can adjust its temperature settings to suit your needs. Ultimately, the best type of mattress for you will depend on your personal preferences and where you live.

Factors to Consider Before Purchasing a Cooling Mattress

If you live in a climate that gets hot during the summer months, or if you tend to sleep hot year-round, you may be interested in purchasing a cooling mattress. Cooling mattresses are designed to help regulate body temperature, keeping you cool and comfortable all night. But with so many options on the market, it can be challenging to know where to begin. Here are a few factors to consider before purchasing a cooling mattress:


If you only need a cooling mattress for the occasional hot night, you may not need to invest in the coolest beds on the market. But if you live in a climate that regularly hits 90 degrees or more, you'll want to ensure that your mattress can keep up.

You will also want to consider your options if your location shifts between extreme cold and hot temperatures. Instead of purchasing a permanent cooling mattress, you may consider getting a regular memory foam or traditional mattress with an add-on cooling pad or active cooling system.

It's important to keep in mind that not all cooling mattresses are created equal. Some cooling mattresses are better suited for certain climates than others. For example, if you live in a particularly humid environment, you'll want to ensure that your cooling mattress has a moisture-wicking layer to help keep you dry.

Type of Sleeper

If you tend to sleep hot, regardless of the climate, you'll want to look for a mattress with ample cooling features. At the same time, you will want a mattress that properly supports your spine. Side sleepers, in particular, will want to look for a mattress with cooling features and a softer top so that their hips can sink into the mattress and provide a better alignment. Stomach sleepers will want to find a cooling mattress that is firm enough to support their hips and spine but not so firm that it causes discomfort. Back sleepers may also want a firmer mattress to help alleviate lower back pain.


When it comes to cooling mattresses, you get what you pay for. The more expensive cooling mattresses on the market typically use higher-quality materials and more advanced cooling technology. If you're on a budget, options are still available. Several cooling mattresses use less expensive materials but still provide adequate cooling. You may also want to consider purchasing a regular mattress and adding on a cooling pad or cooling system, as this can be more cost-effective than buying an entirely new mattress.

Final Thoughts

Purchasing a cooling mattress is a big decision. But with so many options on the market, it can be difficult to know where to begin. Now that you have learned more about different types of cooling mattress technology, you can make an informed decision about which cooling mattress is right for you. Factors such as climate, type of sleeper, and budget should all be considered before making a purchase. With so many options available, there's sure to be a cooling mattress that's perfect for you.
