Our Top 5 Best Cooling Mattress Pads Reviews
Extra Thick Mattress Topper
Bamboo is a very popular and effective material for keeping mattresses cool. It is so effective because it is lightweight and allows air to pass through it. This mattress topper combines bamboo with a blend of microfibers, and the result is a texture that is soft and cool. It is softened with down-alternative fibers that are hypoallergenic, so this topper is ideal for those that like a very soft and comfortable sleeping surface. The topper is double stitched, so you don’t have to worry about the filling coming out. The high-quality construction helps the topper stay soft and fluffy for a long time. It is about one inch thick, so it adds some heft to your mattress without being overpowering.
The fibers add a bit of support, but because they are designed to be cooling, they won’t drastically increase firmness or support your joints the way a memory foam topper would.
This topper comes in six different sizes, ranging from twin to California king, so you can use it no matter what size bed you have. It is also very easy to clean because it is machine washable.
When washed and dried on low settings, it retains its shape while staying clean, so it reduces hygiene concerns. The company offers a 30-day money back guarantee as well for peace of mind when shopping.

Secondly, this topper has some glowing reviews from users who all agree that it has great cooling properties that are down to the hypoallergenic all-natural bamboo fabric which helps to regulate your body temperature as you sleep.

Lucid 3-inch Ventilated Gel Memory Foam Mattress Topper
Many people associate memory foam with trapping in heat, but when you infuse it with gel, it can actually be very cooling as you sleep. This mattress topper is made from Certi-Pur memory foam that is infused with a soft gel that disseminates heat as you sleep, preventing you from feeling overheated or uncomfortable. It also has a unique open-cell design, which allows air to flow in and out of it easily. Most memory foam products are not cooling because they aren’t designed to allow air to pass through them. However, this foam is constructed differently so it will not trap in heat. It is also an ideal mattress topper for those who need extra support while they sleep because the memory foam is very supportive and reduces pressure points during sleep. It molds to the shape of your body as you sleep, so you get a support that is specific to your needs, and you feel cradled and supported at night.
Despite the thick size, this mattress topper fits well on any mattress because it is one inch shorter than a standard bed on all sides, so your sheets will still fit comfortably on top of it.
It does not have the odor that is associated with traditional memory foam toppers. It also holds its shape very well without sagging.
Support for muscles and joints
Cooling feeling of a gel or cooling topper
Great thickness to remove any inconsistencies in a mattress
Made from Certi-pur memory foam

Gel Memory Foam Mattress Topper
This is another memory foam topper that is infused with gel for a cooling sensation as you sleep. The gel is worked through the entire memory foam topper (instead of being in pockets, like you might find with other memory foam products), so it really keeps your whole body. It also has an open-cell design as opposed to a traditional closed cell memory foam design, which allows air to better flow through the product. It’s perfect to pair with an uncomfortably firm or hot mattress because it provides support and increases airflow. The topper is made from Certi-Pur foam that is low density, meaning it feels relatively soft when compared to other memory foam mattress toppers.
However, it still relieves pressure points and reduces pain, just like other memory foam products. It is a full two inches thick, so it adds tons of support to your mattress.
It also conforms to your body as you sleep and reduces motion transfer, so you sleep more soundly with less tossing and turning. It comes in six different sizes, ranging from twin to California king, and fits neatly onto most beds.
The thick size of the topper may cause some problems if you have a particularly thick mattress, to begin with, however.
Provides tons of support
Keeps you cool at night
Softer than most toppers
You may experience some of the stereotypical ‘new mattress’ smell with this topper

This cooling topper comes with a made-to-measure cover which can easily be removed and machine washed, keeping your bedroom clean and smelling fresh.

Cooling Mattress Pad Buyers Guide
What To Look For In Cooling Mattress Pads
A good night’s sleep can be very easily disturbed by overheating. It’s difficult to get comfortable when you’re sweating and really feeling the heat. That’s why cooling mattress pads were invented in the first place; to come up with an innovative but simple solution to bedtime heat woes.
With such a wide variety of mattress pads available, it can be difficult to figure out which one may work best for you.
It’s not uncommon, either, for a company to label their products as having cooling properties when in reality the mattress topper leaves much to be desired in the temperature regulation department.
It’s important that, before making a purchase, you know what to look for in relation to a good cooling mattress pad. It should help you to spread your body weight evenly, like a normal topper, but also have great cooling properties for a better, deeper, more quality sleep.
In order to find a mattress pad that fits the bill, you’ll have to be aware of all its features. To help you out, we’ve compiled a list of things and characteristics to keep in mind while you’re making your decision.
There are an impressive variety of materials available for cooling toppers/pads. Basic and inexpensive toppers may use polyester, cotton, or latex, but better and more comfortable options may be cushioned with wool, fleece, down, or memory foam.
Typically, memory foam that is infused with cooling gel is the best option for both comfort and temperature regulation.
The gel pad prevents overheating by controlling temperatures, stopping them from jumping to uncomfortable heights. The memory foam itself will work even better if it is open-cell or ventilated foam, which allows for better airflow throughout the pad.
Another form of mattress pad that can be great for a cool night’s rest is a down feather pad, which regulates temperature much better than other similar toppers. They tend to come at a higher price point, but what they lack in affordability, they make up for in comfort and luxury.
Latex is also a recommended material, and it’s more environmentally conservative than the other aforementioned ones.
It tends to be resistant to dust mite and mold, and as such, are more durable and can even last up to 20 years! Of all the less expensive materials, it is also the best at ensuring a good amount of temperature regulation.
The cover of a cooling mattress pad should ideally be made of 100% cotton or something similar in order to promote maximum comfort. But some companies actually manufacture products with special cooling covers too, so you get double the temperature regulation.
After considering the cooling properties of each material, it’s then up to you to decide which material will offer you the most comfort.
In order to allow you to judge for yourself, we’ve come up with a breakdown of the most common and popular mattress pad materials. Some mattress pads may combine two of these features for a better temperature lowering effect.
This material shapes itself according to your body, which provides paramount support and comfort. It’s also known to be quite durable. However, non-ventilated foam has a tendency to trap hear within it and can counteract any cooling ability a pad may have, so gel-infused foam works best.
Latex – This green material is environmentally-friendly and is also known to be rather versatile. Its firmness is also great for providing support to the body – especially the back – and can be found in very high qualities and feel luxurious.
Feathers or Down – These mattress pads are known for being incredibly comfortable and soft, especially if your mattress is firm. However, they aren’t the best for support and they can feel lumpy or uneven if not bought at high quality. If you have allergies, it may not be the best choice for you!
Fiber – If you want the feel of down without its negative properties, you can opt for fiber, which mimics feathers but it highly hypoallergenic. They provide a decent amount of support and are usually great for those on a budget
Wool – This is a fantastic material for all seasons that can keep you cool in warm months and warm in cold seasons. It’s extremely durable can is usually of average affordability, but it can be difficult to get it to stay in place on top of a mattress.
Organic – No, this isn’t a specific material in particular, but it is an option for you if you prefer to purchase organic products only.
Latex and wool mattress pads can sometimes be certified organic even if they aren’t 100% organic, so you may have to do your research about these products as well as their manufacturers.
Types of Cooling
There are many forms of cooling functions that allow for a mattress pad to regulate temperatures. It isn’t all about the ventilation properties of the materials themselves. Some high-end mattress toppershave surprisingly advanced and elaborate functions in order to fulfill their purposes.
There are two forms of cooling effects: active and passive. Active cooling involves products that come with accessories that are designed to cool you as you lie on it.
For example, some may come with mattress fans or a cooling unit that needs to be attached to the pad. Some pads even use a liquid tubing system to regulate temperatures.
The great thing about active cooling is that you can control these functions to work exactly to your specifications. You can make your mattress pad cooler or warmer based on climate, temperature, and your personal preferences.
Many of these types of mattress pads can even warm your bed during colder nights, and some of them have dual zone settings so that two people can sleep on the mattress pad at the temperatures that they personally want. It’s a customizable experience all in itself!
There is a downside, though. These pads require a constant flow of energy, usually electrical, in order to work, and they are usually much more expensive than passive cooling pads. However, for optimum sleep in exactly the way you want, these work great.
On the other hand, passive cooling occurs in a pad that has gel-infused materials and plenty of good ventilation in order to create a nicely aerated space and open cells.
This causes airflow to become much smoother, catching heat within the spaces and then transferring them outwards to disperse. Meanwhile, the gel has cooling properties that make any material much more comfortable and less warm to the touch.
Some passive mattress pads make use of microencapsulated thermocouples in order to trap extra heat circulating around, and only lets the heat go when the temperature becomes too cold.
This is a patented format known as Outlast and is used in some company’s and manufacturer’s products in order to regulate body temperature as it is rising or falling in a seamless manner.
Passive mattress pads are probably the more convenient and hassle-free form of a topper.
There is no energy required to use it, and you don’t have to maintain its features in any way apart from basic washing and care. These also tend to feel more luxurious and relaxed, and much softer when in use.
But then, right smack in the middle of these two options, are semi-passive cooling pads. How do these work? Typically, they are mattress pads that require refrigeration or freezing before use.
This gets rid of the heat it currently harbors, and then holds on to the cooling effects it received from the fridge when you finally do use it. These tend not to last as long, though and need regular refrigeration, so it can be a bit of a hassle.
Semi-passive cooling pads of higher quality can also be used for heating functions by popping them into the microwave before use.
However, you should only do this to your semi-passive topper if the package specifically says it can be done – don’t just go around microwaving all your mattress pads, please!
So which cooling option works best for you? Depending on how much you’re willing to spend and how much free time you have to spare, these options are all readily available!
Mattress pads usually come with a density rating, which usually runs from 3 to 5, and, as you guessed, informs you of the total density of the topper.
Essentially, density can have an effect on the cooling abilities of a product and change the comfortability of the pad. With that being said, opinions on the most comfortable density tends to differ from person to person.
Here’s what you need to know: dense mattress pads don’t have as much sink to them, making them feel firmer, thicker, and not as soft as a less dense topper. However, this means that there is more support provided for a sleeping form.
Usually, having a dense mattress pad means it retains a higher amount of heat, although there are some designs that specialize in allowing ventilation to regulate temperatures.
If you have a back problem or are of a higher weight, a thicker and denser mattress pad will usually be the best option for you as it will provide more support. If that’s what you’re going for, you’d want a mattress pad of a density of at least four.
A denser pad may also be more durable in the long run. But aside from these considerations, you’ll have to consider your own preferences in terms of comfort and softness!
A Note on Firmness
Many have argued over whether a firm, soft, or somewhere-in-between mattress pad works best for comfort, but the fact is that it depends on what you like.
A softer mattress pad will fit your body’s contours and allow you to really feel the sinking-in sort of comfort that many bedding companies advertise.
Firmness offers more support, and some people personally consider this to be more comfortable than soft pads. You’ll have to work out what works best for you!
While the previous features are the most important ones to think about when purchasing a new cooling mattress pad, there are also some other factors to keep in mind before you buy.
Size – This kind of goes without saying, but your mattress pad should fit the mattress you have so that it doesn’t shift. Be aware of the depth of your mattress before buying. Purchasing a mattress pad doesn’t properly shift can cause creases and lumps which are quite the opposite of comfortable.
Sleeping Position – It’s often stated that you need to shop based on your most used sleeping position. If you sleep on your side, you’ll need a product that’s thicker and softer, but if you sleep on your stomach, you may need a thinner product.
With that being said, since a large majority of people change positions throughout the night, you can just choose based on what feels most comfortable if you don’t have a particular way of sleeping.
Pest and Allergy Control – You should get a high-quality mattress pad that prevents bedbugs or dust mites from infesting it and causing you more problems later on. If you have sensitive skin, then look for a mattress pad that’s labeled as hypoallergenic.
Some of these anti-pest and anti-allergy mattress pads even come with a wide zip, so that they can fully cover your whole mattress and prevent anything from sneaking in.
Care Requirements – Based on materials, different pads will have different needs. Some require dry cleaning, and others are machine-safe and very easy to maintain. Mattress pads that have gel infusions or down fillings may come with their own set of cleaning instructions, so try to follow them as closely as possible.
Warranty – This is especially important if you purchase a more expensive mattress pad or one with lots of extra features. A long warranty is a sort of guarantee for a product, so make sure you know the warranty information before purchasing.
It’s also a good idea to already know the procedure of getting a refund or exchange on the product if it’s faulty.
What Not to Expect from a Cooling Mattress Pad
Unfortunately, cooling pads don’t work as the complete opposite of a heating pad. This means that they cannot fully cool down a bed to a specific temperature, and especially not with the changing climates.
So if your room is already very warm, a cooling pad may not be able to help you with temperature regulation any more than turning on a fan will – if it did, that would quite go against physics!
Why is this the case? Well, a pad collects heat from your body, and then it needs to release all that heat back out somewhere.
When the room itself is already warm, the pad cannot dissipate any of the heat it is holding in an effective manner – and especially not a passive cooling pad! Active cooling pads will work much better in this scenario, but the fact is, even it has its limits.
If you tend to overheat or sweat a lot at night, passive cooling pads may not be enough for you.
Using an active pad can overcome that, but expect to pay more for the added features and electricity needed to run the cooling mattress pad. It’ll still be cheaper than racking up the bill for nightly air conditioning, though!
Some Final Words About The Best Mattress Topper
When choosing a cooling mattress to make those hot, sticky and sleepless nights more bearable, remember to pay attention to the user reviews and more importantly the returns policy.
If you find that your cooling pad doesn’t quite fit the bill, most retailers will accept a return within a set time period.
This is why we recommend shopping with Amazon directly as they have an excellent and simple online returns system which provides peace of mind which is crucial when shopping online.
