When you’re in the market for a new mattress, buying a quality one doesn’t come cheap. Protecting your costly investment means investing in a mattress protector as well. Think of it as insurance for your mattress. You save yourself a ton of money in the grand scheme of things extending the longevity of your mattress. So, what are the qualities that a good mattress protector should have?

First and foremost, all the best mattress protectors should be waterproof to protect your mattress against stains and spills. They should also be allergen-resistant and provide you with ample protection against dust mites, bacteria, and other allergens. On top of that, a decent mattress protector should feel comfortable while sleeping and maintain an optimal temperature all night long. This is where a cooling mattress protector can help.

Cooling mattress protectors are similar to cooling gel pillows in that they prevent heat from getting trapped between your head and the pillow. A mattress protector with gel fibers soaks up heat quicker than other fabrics, but it’s not the only type of cooling material you can use. You can also choose naturally breathable fabrics such as hypoallergenic cotton and eco-friendly bamboo.

As with all things you could buy, there are positives and negatives to each cooling mattress protector, but they will all do a good job of keeping you cool during the night.

The Best Cooling Mattress Protectors Reviews

COOP Home Goods: The Best Naturally-Cooling Bamboo Mattress Protector

This Coop Home Goods cooling mattress cover is made of both polyester and bamboo-derived rayon, which gives it a smooth, lavish finish that contradicts the low price tag it’s sold at. However, bamboo is more than just for looks in any product it’s used in. It’s also antibacterial, hypoallergenic, and helps with temperature regulation.

This particular cooling mattress protector can be used on mattresses up to 18” deep and fits like a fitted sheet. The underlying membrane is waterproof but also breathable and promotes airflow.

The difference between this waterproof protector and similar ones is that the Lulltra doesn’t crinkle each time you move. Rather, it remains completely silent and is super soft, much like sleeping on a cloud. It’s an OEKO-TEX certified product, which means there were no toxic byproducts used in its manufacturing.

Some users have complained that it’s not near as durable, but its protection and cooling features are above par. According to the manufacturer, the protector can be washed in a washing machine using cold water and be thrown in the dryer on tumble dry low. To extend its lifespan, make sure you abide by these instructions.

COOP Home Goods does also provide a 100-nights’ sleep trial along with a five-year warranty in case you end up with a defective unit. What makes the Lulltra so worthwhile? It’s a cheap solution designed for people who want to ensure their mattress stays in great shape without sacrificing their comfort.

Malouf: The Most Comfortable Option

Malouf’s cooling mattress cover uses a cotton terry fabric for its surface layer, which ensures its softness and noiseless features. It’s also absorbent, so it eliminates moisture resulting from sweating. With its Sleep Tite H2Pro waterproofing technology, air can pass freely through the cover while keeping out the bigger particles such as allergens, dust mites, bacteria, liquids, and more.

The protector is designed to fit mattresses 22” inches in depth or less and contains no dangerous byproducts like PVC, phthalate, and vinyl. If you’re looking for an eco-friendly product, this may be the one for you.

There has been talk of defective waterproofing, but it’s not known if the defect is manufacturer-flawed or user-error (not washing it correctly). Still, the manufacturer does offer a 15-year warranty, and the replacement should be laundered per the manufacturer’s instructions.

If you want to protect your mattress from liquids and dangerous allergens while also keeping you cool at night, then you want to get this cooling mattress protector from Malouf for your bed.

Protect-A-Bed: The Most Breathable Option

Tencel is one of the best fabrics to use in hot, humid climates. After all, it can dissipate heat, absorb moisture, and protect against bacteria and other allergens. It’s got a cool, elastic feel that doesn’t give you the plastic sensation that a waterproof membrane often has.

Instead, Protect-A-Bed cooling cover uses a Miracle Membrane – a thin, breathable membrane – that can keep allergens and fluids out while also keeping it cool.

The majority of people who have used this protector noted that it works as it claims, and love its cooling properties and overall comfort. However, there are multiple complaints of defective waterproofing; therefore, you should test it out before you put it on your mattress.

But all in all, if you want the Tencel cover benefits at a great price, this could be the mattress protector you are looking for.

Leggett & Platt: The Coolest Mattress Protector

There are two primary reasons this cooling mattress cover is better than others on the market.

It’s infused with cooling gel, which isn’t cool when you touch it and doesn’t make you feel as if you’re in the Arctic. Instead, it’s got a ventilated design with crystal gel fibers that will soak up the heat much quicker than other protectors on the market. With better airflow, you stay cool and sweat-free all night long.

The protector’s top comprises of both polyester and Coolfiber, with the back made of 100 percent polyurethane that will last longer than cotton and other natural fibers. Polyurethane is well-known for its ability to guard against stains and liquids, making it a must-have in mattress protectors.

Leggett & Platt offers their cooling mattress protector in eight sizes, including the rare full XL and split king. According to some reviewers, the cover tends to slip, which can be addressed using sheet suspenders. With a 10-year limited warranty, this may be the right product for you.

SafeRest: The Most Affordable Cooling Mattress Protector

This reasonably-priced cooling mattress cover is one of the best in a market where protectors can cost nearly $100. It’s made entirely out of cotton terry, which means it can naturally breathe and is also hypoallergenic and waterproof. Plus, it can easily whisk perspiration away.

If you suffer from allergies, the SafeRest cooling mattress protector can keep them at bay. While it may not last as long as polyurethane mattress covers, it is still very effective in keeping you cool and healthy as you sleep.

The SafeRest mattress protector will fit mattresses up to 18 inches deep and has six sizes it can be purchased in. Best of all, the product is OEKO-TEX Certified, and it doesn’t change the feel of your mattress.

Zen Bamboo: The Best Lab Tested Option

The Zen Bamboo cooling mattress cover is comprised of 40 percent bamboo-derived rayon and 60 percent brushed microfiber. The main aspect behind this mattress protector is its ability to move heat away from its surface. Bamboo allows for plenty of airflow; it means that heat can dissipate more easily. Since bamboo is also hypoallergenic and antibacterial, people who suffer from allergies will benefit most from this cooling mattress cover.

The protector’s waterproofing abilities are quite high, which is amazing as it doesn’t cost a lot of money. Since it’s OKEO-Tex-certified, you don’t need to be concerned about harmful byproducts such as PVC, phthalates, and vinyl. The manufacturer offers a 30-day money-back guarantee accompanying a lifetime warranty, which isn’t something you see with a lot of other protector manufacturers.

If you want a high-quality cooling mattress protector that allows you to keep money in your wallet, then you need to consider Zen Bamboo for your bed.

Why Do Mattress Protectors Make The Bed Hot?

The plastic membrane is the main reason why your mattress gets hot. This membrane is designed to keep the bacteria, pet dander, dead skin, water molecules, and other things out of your bed but still let air flow through. However, if you’re using a non-porous material on your mattress, then it won’t allow completely free passage of air.

This airflow restriction is keeping heat from escaping the bed, which leads to a rise in temperature that may cause you to sweat during the night and hinder you from getting good quality sleep.

How Can A Cooling Mattress Protector Ensure You A Better Night’s Sleep?

There are special mechanisms used in a cooling mattress cover that enables it to remove heat from the bed’s surface, ensuring the temperature can go down. It may do so through phase-changing materials or breathable fabric, which can regulate the temperature to a bearable limit. 

Should You Use A Cooling Mattress Protector?

You may not like the idea of using a mattress protector initially, but after a week or so, you’ll get used to it, including the slightly raised temperature. Thus, getting a cooling mattress protector may seem like you’re just throwing money away. But, there are a few instances in which it’s better to purchase a cooling cover right from the start:

You Have A Medical Condition 

Menopausal women often suffer from hot flashes during the night. A cooling mattress protector can dissipate the excess heat so that you can rest comfortably all night long while also protecting the mattress from excess sweat that can ruin the bed. 

You Live In A Tropical Region

If you live in a region of the world that gets hot and humid, you are going to want a mattress protector that keeps you cool as you sleep. A regular mattress protector will only add to the heat, which is not going to make you feel comfortable as you sleep.

Your Mattress Is Already Hot 

If your bed is already warm when you sleep on it without a mattress protector (something you’d see with a cheap memory foam mattress), then you’re liable to sweat if you add on a plastic protector. In this case, it would be in your best interest to buy a cooling mattress cover (spending the money upfront saves you grief down the road). 

What Makes A Good Cooling Mattress Protector?


When it comes to materials, you typically have four different choices:

PCMs – These materials are the scientific answer for thermal management. They help to store and release heat based on the outside environment, which makes them good at temperature regulation. When it comes to PCM mattress protectors, they can keep you cool in the summer and warm in the winter.

Tencel – This “branded” fabric is made from eucalyptus trees in an eco-friendly manner. It’s well-known for its soft and absorbent properties. Not only does it absorb more moisture than cotton, but it is also inherently breathable and antibacterial. However, Tencel material does cost more, which means any protectors comprised of it will be considerably more expensive. 

Rayon – This material comes from bamboo fiber, which is extremely soft and helps with temperature regulation. It can also absorb moisture and has anti-bacterial properties. It’s not durable on its own, which is why rayon is often combined with polyester to ensure breathability and comfort. When a manufacturer uses bamboo rayon for a protector, it can help to cool down your bed. 

Cotton – This is a breathable material that can absorb a fair amount of liquid, and when used in as a cover, it can help dissipate heat. It’s not fully waterproof, which is why it should only be used as a surface material and needs to be backed up by a PU membrane to offer real protection.

Moisture Wicking

While not tied directly to bringing temperatures down, a good protector will absorb sweat to ensure a better night’s sleep, especially in a hot, humid climate such as the topics. Sweat buildup can wake you from a deep sleep because you start to feel sticky and clammy. So, a cooling cover that will whisk moisture away and ensure you get a good night’s rest. 

It’s important to understand that throwing such a product in the laundry often can get rid of the excess fluid, but will eventually lead to a breakdown in its protection. This especially true of the less expensive models because their membranes break when thrown in the washer too often. 

Micron Size 

This refers to the size of the microscopic holes, which are found in the waterproof cover membrane. The smaller the holes a protector has, the better it’s going to be in keeping allergens and moisture out. However, this also means less airflow and heat dissipation. 

The most powerful water and allergen proofing begins at one micron or less and is only recommended for people who suffer from serious allergies or are at high risk for fluid-related accidents. Sleepers who want a protector for occasional accidents will do well with a higher micron size. 

The higher the micron size, the more air can pass through, which ensures you don’t run hot while sleeping. Keep in mind that some protectors have no holes in them whatsoever, which means absolute protection from moisture, but you can guess that they lead to serious hikes in the temperature of your bed.

Should You Go With A Five-Sided or Six-Sided Cooling Mattress Protector?

Now, when it comes to what kind of cooling mattress protector to get – a five-sided or six-sided one – you need to know the differences. A five-sided protector covers everything but the bottom of your mattress, whereas a six-sided protector encases your mattress and will protect it from bed bugs

Now, with a six-sided protector, heat is unable to escape as easily, which means your mattress will warm up. A fitted sheet-style protector (five-sided) means the bottom of the mattress will have air flowing through. 

Which one is the better option? Ask yourself this one question: Is there a cause for alarm with bed bugs? If not, then a fitted sheet (five-sided) style cooling mattress protector is the way to go. Otherwise, go with the six-sided encasement protector. 

How Can You Stay Cool While Sleeping?

Discussions have been ongoing about the benefits of staying cool while sleeping, and there are many of them out there. A cooler environment means you not only fall asleep faster, but you wake up feeling refreshed and rested, ready to face your day. 

The reality is that temperature and humidity play a huge role in your sleep quality. However, there are plenty of things you can do to ensure that you get a better night’s sleep – one of which is getting a cooling mattress cover for your bed. What are some other things you can do to improve your sleep environment?

Cooling Pillow

In the winter, people tend to use a hat to keep their head warm (to lock in the heat generated by the body). This idea can also be applied to your bedroom (more notably, your pillow) to keep it cool as you sleep. A cooling pillow will help in regulating your temperature when and where it matters.

Use Breathable Fabrics For Bedsheets

When it comes to bed sheets, you don’t want the fabrics touching your skin to absorb moisture and trap it next to your body. Be sure to look for breathable material for your bedsheets.

Keep Fans Running 

Fans do a great job of keeping the air cool since they can circulate the air and evaporate sweat from the skin. This will help in keeping your body temperature regulated. If you have a ceiling fan, use it during the summer with a counterclockwise direction to give it the downward airflow. In the winter, you want to set it to move clockwise, so the fan blades make the air go upward to redistribute warm air. 

Maintain A 30 to 50-Percent Relative Humidity

The reality is that it’s not always the heat that disturbs your sleep, but the humidity. Even a moderate temperature can feel too warm when mixed with excess moisture in the air. Why is that? 

Humidity keeps the body from being able to maintain its body temperature naturally through sweating. With a 30-50 percent humidity level, you stay comfortable, and the chances for mold and dust mites to proliferate are greatly reduced. Be sure to get a humidity gauge for your room to see how much humidity is in there.

Maintain A 67-Degree Room 

Most people, when talking about keeping cool at night, mention the room temperature. While personal preferences will dictate what the ideal temperature is, 67 degrees Fahrenheit is considered the optimum sleeping temperature for comfort while sleeping. 

Regardless of the season, you should always have a steady room temperature, which can be done with the home thermostat. If your home is set up with a smart home system, you can program settings for increased energy savings during the day and a lower temperature at night. With most thermostats in the home’s hallway, a separate thermometer for the bedroom will ensure a better read on the temperature. 

What Should You Keep In Mind…

Nearly all manufacturers will claim their protectors do not increase a bed’s temperature. However, you must do your research to find a product that has been deemed a cooling mattress protector. 

With this helpful guide, you now have a better idea of what to look for in a cooling mattress protector – one that offers breathability and moisture-whisking features and uses cooling fabrics to keep you cool as you sleep. Always look at user feedback to help you decide which cooling mattress protector is best for you and your needs.
