Now that you know all about the cooling technologies and qualities of some of the best memory foam mattresses, your head must be swarming with tons of questions. So, in this section, we’ll answer some of the most frequently asked questions regarding memory foam mattresses to help resolve your doubts. Let’s take a look! 

Are Eco-Friendly Mattresses Cooler?

An eco-friendly mattress doesn’t involve any material or production method that can negatively impact the environment. Before we talk about the cooling features of an eco-friendly mattress, it’s essential to understand what makes a mattress eco-friendly.  

There are certain certifications that determine the degree of eco-friendliness of a mattress. For instance, the Global Organic Textile Standard (GOTS) highlights that the mattress contains 70-95% of organic fibres to ensure environmental sustainability. At the same time, the Oeko-Tex Standard 100 certification ensures that the mattress material doesn’t have any toxic substances that can be harmful to your health. 

Moreover, eco-friendly mattresses come with CertiPUR-US certification to signify that the foam doesn’t contain certain heavy metals and harmful chemicals. There are also some other quality standards that a mattress needs to go through before being considered eco-friendly. 

Now, coming back to the question about the cooling properties of eco-friendly mattresses. It’s not necessary that every eco-friendly mattress will offer a cool and comfortable sleeping experience. However, the organic fibres of an eco-friendly mattress enhance its breathability and airflow, making it more effective in regulating body heat compared to standard memory foam mattresses. 

Furthermore, eco-friendly mattresses do not contain any heavy metals or chemicals that can trap heat. The organic and natural materials of the mattress automatically facilitate better temperature regulation and heat dissipation. But on comparing it with mattresses having gel-infused foam, you might find that the eco-friendly mattress is not as effective in offering a cool sleep environment. 

In that case, you can always go for eco-friendly mattresses having a gel-infused foam layer that’ll offer advanced cooling features, along with environmental sustainability. The gel-infused eco-friendly foam mattresses are much cooler than normal eco-friendly mattresses and offer better heat dissipation while you’re sleeping. But, it’s always best to go through the certifications of the mattress to determine its eco-friendly quality. 

2. Do You Need An Expensive Mattress To Keep Cool?

If we talk about modern hybrid memory foam mattresses with superior cooling features, they are usually more expensive than regular memory foam mattresses. The quality of the materials and the production methods are usually the main factors that determine the cost of a mattress. So, naturally, mattresses made from high-quality materials like organic fibres will cost more. 

Furthermore, the density and firmness of a mattress greatly impact if the mattress is cheap or not. The heavy natural latex mattresses with a higher density are always more expensive than the low-density synthetic mattresses. Plus, the cost of the mattresses increases with construction and design. Hybrid foam mattresses that offer better airflow and breathability are generally costlier than other memory foam mattresses. 

On top of this, mattresses that are infused with cooling agents, like graphite or a cooling gel, are obviously more expensive because of their advanced features. However, it’s not necessary that you have to invest tons of money to keep your mattress cool. Most leading mattress manufacturers in Australia offer a reasonable price for their premium-quality cooling foam mattresses. 

Not only that, but you can also save a lot of money by purchasing cooling bed accessories instead of replacing your entire mattress. You can add pillows and pillowcases, weighted blankets, or mattress pads that can work beautifully to keep your mattress material cool and comfortable. Thus, you get a lot of options to keep the mattress cool even if you’re running on a tight budget. 

How Can I Cool Down My Mattress?

There’s no point in wasting tons of money on a cooling foam mattress if you’re going to use bedding materials that work against the cooling properties of the mattress. Hence, you must know about the special sleep accessories that can help you keep the mattress cool and comfortable. 

A. Pillows

Pillows are arguably the most important sleep accessory apart from your mattress, and there are some specially designed cooling pillows that can keep the mattress cool. Usually, pillows made from shredded latex filling or having a gel construction work best to retain the cooling properties of your foam mattress. 

You can also use bamboo pillows containing natural and organic fibres that can maintain a cool and comfortable sleeping environment. It’s always a good idea to go for pillows made from natural fibres for keeping the mattress cool. Once you select the best cooling pillows, make sure to cover them with high-quality cooling pillowcases. 

B. Covers 

Along with choosing the right pillows, you also need to select the right sheets to keep the mattress cool. The comfort and dryness of the sheets become a top priority of hot sleepers, so it’s best to look for sheets that come with moisture-wicking materials and are ultra-soft. Some great cooling materials for your bed sheets can include polyester microfibers, bamboo, linen, or lightweight cotton. 

When we’re talking about cooling covers, weighted blankets and comforters also play a central role. Weighted and cooling comforters can enhance the heat dissipation quality of your memory foam mattress and prevent overheating while you’re sleeping. They can offer the ultimate cool and peaceful sleeping experience for a restful slumber. 

In addition to this, you can also look for mattress pads that can keep your mattress cool. They can help provide additional cooling without requiring any extra financial investment. So, if you have a limited budget, mattress pads can be the best choice for cooling down your foam mattress. 

Why Does My Mattress Make Me Sweat?

Don’t always blame your fan or cooler every time you wake up sweaty in the middle of the night. In fact, it might be your mattress that’s adding to your discomfort and night sweats.

For instance, soft mattresses can feel a lot more comfortable to sleep on because they offer a sinking feeling. But you also lose a lot of air exposure when you’re sleeping on a soft mattress. 

Our body’s ability to regulate temperature depends on body-to-air contact, so with minimum air exposure, the body automatically heats up. When the surface area of your skin loses air exposure, it fails to cool you off, resulting in overheating of the body.

In contrast, firmer mattresses facilitate better exposure to air to prevent sweating and create a comfortable sleeping environment. But, if your mattress is old and saggy, it’s probably the main reason behind your night sweats. Old mattresses lose their firmness over time, and that’s why you get the sinking feeling every time you take a nap on an old mattress.

The pocket springs and foam layers of an overly used mattress lose their bounciness and lumbar support, making the mattress saggy. Thus, if the mattress is making you sweaty and ruining your sleep, it’s time to replace it. Buying a new mattress can help you get a peaceful slumber without experiencing night sweats. 

However, if your buying a mattress for Airbnb or your home it’s always a good idea to check the design and construction to ensure better airflow and breathability. If your new mattress has a dense foam layer, it can also cause overheating and excessive sweating while you are asleep. Thus, mattress construction and its age can cause your foam mattress to cause sweating and disrupt your peaceful slumber. 

Why Are Memory Foam Mattresses So Hot?

Generally speaking, memory foam mattresses trap more heat, and more users complain that their memory foam beds tend to overheat quite easily. As these mattresses retain more heat, you end up feeling sweaty and uncomfortable while sleeping. While standard memory foam mattresses are great for alleviating your pressure points, they are not ideal for creating a cool sleeping environment. 

The foam layers are quite dense and contain air bubbles that are often disconnected, limiting breathability and airflow. When you sleep on these mattresses, they become compressed, and the air bubbles get displaced, restricting airflow. With this limited airflow, body-to-air contact is lost, which prevents your body from self-regulating temperature.
Hence, feeling overheated while lying on a regular memory foam mattress is a normal occurrence. 

The low resilience and dense design of standard memory foam mattresses result in moisture and heat retention, making you feel sweaty and restless while sleeping. Plus, the lack of firmness adds to the heating quality of these mattresses. Your body tends to get overheated when you’re sleeping on a bed that’s too soft. 

The plush materials lead to sinkage, creating a hugging or cradling feel. However, if the foam layers have no cooling properties, the cradling sensation can lead to discomfort and excessive heat build-up that can ruin your peaceful slumber. So, even though regular memory foam mattresses can feel very soft, the heat retention and restricted airflow can make the entire sleeping experience quite stuffy and sweaty. 

But, you can easily remedy this problem by choosing modern cooling foam mattresses that come with gel-infused foam layers and are firmer than standard memory foam mattresses. Copper or graphite-infused hybrid mattresses are also effective in dissipating excess heat. In addition to this, you can use cooling pillows, weighted blankets, and mattress covers to keep your mattresses cool and comfortable.

Final Verdict

Choosing the best cooling memory foam mattresses for hot sleepers is not an easy task, especially when you have so many great options out there. You have to look through their cooling technologies, firmness, and foam layers before selecting the best mattress
