Difference Between a Mattress Pad and Mattress Topper

Both mattress pads and mattress toppers make great room decor, mainly if they feature attractive designs or covers. They also make a great addition to guest rooms and other sleeping areas in the house where some furniture or bedding surfaces may lack proper support to make it comfortable enough to lay down or sleep.

While both mattress pads and mattress toppers provide similar functions, they also have different features that set them apart from each other.

  • Mattress Pads

These are usually thinner and provide minimal cushioning. These are typically filled with down and down-alternative fills. Because of their thinner nature, they work best with quilted pillow top design covers and have elastic fitted sheets. They are primarily used to protect the mattress.

  • Mattress Toppers

They are thicker and provide more cushion and support. These are foam-based and usually utilize temperature-regulating technology to allow them to conduct body heat away from the sleeper and evenly distribute within its porous structure to eventually dissipate the heat to make the sleeper relaxed and comfortable.

Types of Mattress Toppers

A mattress topper isn’t just all foam and cover. There are two types of mattress toppers, and being able to identify the differences between each type might influence your decision on buying that perfect mattress topper you have been hoping to buy.

  • Active Cooling Toppers

This category goes further than foam and fabric. As a matter of fact, this type of mattress topper uses attachable fans, water pumps, or other cooling devices that provide the sleeper a relaxed and comfortable sleep. These come in various customizable designs that allow for more accurate temperature controls that will enable sleepers to adjust to suit their preferences freely.

Despite all these benefits, active cooling toppers have several disadvantages:

  • These are far more expensive, and the upkeep cost is high
  • Due to external or electrical components, these are far too noisy
  • These are difficult to transfer or move around
  • These are not as common, and product availability is limited

  • Passive Cooling Toppers

Passive cooling toppers are built with specialized materials that allow the absorption and transfer of body heat. This category is cheaper than the other and does not use external devices. It also has subcategories of its own that are determined on what type of materials they are based on.

  • Natural latex foam

This a rubber-type passive cooling topper based on rubber tree saps.

  • Memory foam

Passive cooling toppers built using polyurethane-based material treated with chemicals to make it soft and responsive to temperature.

  • Gel-infused Memory foam

These are memory foams infused with cooling gel beads or gel swirls.

Because of the chemical nature of passive cooling toppers, they suffer from the usual off-gassing smell that is usually present after first opening the product from its sealed package.

What type of sleepers need a cooling mattress topper?

Getting a cooling mattress topper isn’t just a luxury for some people; it is a necessity. Several factors will push them to purchase one not out of want, but out of need. Sleep is an integral part of human activity, and getting sufficient sleep without discomfort after waking up can be hard to obtain, especially in this busy, modern age.

Different types of sleepers have varying needs that are distinct to them. However, the following types of sleepers all need a cooling mattress topper because of the benefits that would apply to them.

  • Positional Sleepers

All three of the usual positional sleepers will need a cooling mattress topper. Side sleepers would feel more comfortable and wake up with no issues with a firm, cooling memory foam. Stomach sleepers need a soft conforming surface that doesn’t only support their belly but also keeps their backs from curving, which could, otherwise, lead to discomfort when waking up. For back sleepers, they need a thinner mattress topper to facilitate sufficient spinal support.

  • Sleepers in warm and humid climate areas

Cooling mattresses are god sent to these types of sleepers. Turning on the AC for most of the time of the day can be very expensive to maintain, and purchasing a cooling mattress topper is an excellent investment to reduce power consumption at night time. Even if cooling mattress toppers aren’t as effective during the day where the hot weather can be overbearing, every little bit of coolness can help.

  • Sleepers who want more comfort

Sometimes it can be hard to fall asleep when you feel your level of comfort is not enough. Despite having a very comfy mattress and pillow, some people would want more. Having a cool mattress topper is a perfect remedy for this longing. It’s never wrong to desire for something more as long as you deserve it.

  • Menopausal Sleepers

Women undergoing menopause experience hot flushes due to hormonal changes. These are common, most notably at night. Cooling mattress toppers can help relieve these nighttime discomforts thanks to its much-needed cooling properties.

Advantages of Cooling Mattress Toppers

Cooling mattress toppers are usually viewed as items of luxury – unnecessary products that only serve a redundant purpose that is already covered by thick and comfortable mattresses. However, that is a misconception. Just like adding ice to a cold beverage, some people would always want something more for an enhanced satisfaction or experience.

Cooling mattress toppers offer several advantages that don’t only benefit the sleeper but also benefit the room and the mattress itself.

  • Additional Layers of Comfort

If you wish your mattress were thicker but can’t afford to replace the one you have, getting a mattress is a perfect and cost-effective solution to this. Getting an extra two or four inches of cushioning can feel great and will definitely improve your sleeping experience. Even if they already have enough cushions, some people sleep better with more padding beneath them.

  • Temperature Regulation

Cooling mattress toppers are designed to absorb and distribute the sleeper’s body heat and dissipate it in the air to allow a relaxed and comfortable sleep.

  • Orthopedic Support

Memory foams are uniquely designed to help prevent or reduce discomfort from pressure points by allowing the mattress topper to conform to the sleeper’s body curve. Cooling mattress toppers offer sleeping benefits to all types of positional sleepers so that they can sleep soundly without waking up from any discomfort the next day.

  • A Layer of Protection

Because mattress toppers are placed on top of the mattress and are far thicker than blankets and bed covers, these also serve as a layer of protection from elements that may cause damage and reduce the longevity of the mattress. These elements include moisture, spilled liquids, and even odor. There are a lot of mattress toppers that have odor-resisting and moisture-absorbing properties, so it also sounds like a reasonable investment.

  • Lower Energy Consumption

This is especially true when you live in hot and humid climates. Having a cooling mattress topper is a cost-effective alternative to turning on the AC at night.

Disadvantages of Cooling Mattress Toppers

Just as cooling mattress toppers offer attractive benefits, they too have their disadvantages. It can be quite appalling to realize that even something as wonderful as cooling mattress toppers have flaws, but nothing is perfect.

  • Lack of anti-slip support

Several cooling mattress toppers don’t come with anti-slip features. The usual complaint among consumers is that their mattress topper doesn’t stay in place and tends to slip out while you toss and move around in your sleep.

  • Loss of elasticity

While some mattress toppers do have anti-slip features using elastic skirts, these tend to loosen over time and can cause the same problems as having none at all.

  • Incompatibility

There are mattress toppers that do not come in the same measurement for their corresponding sizes. While some do, it can also pose a problem to those who do not have usual sized mattresses, which can pose a difficulty in finding the right pairing.

  • Difficult to clean

Some cooling mattress toppers do not come with a cover, and it is highly recommended to purchase one before using one that doesn’t come with a cover. The main reason is that it can be challenging to clean stained and contaminated foams. Sometimes the damage could be so bad you’d be forced to buy another cooling mattress topper.

What things to look for when buying a cooling mattress topper

Choosing the perfect cooling mattress topper isn’t an easy ordeal. It’s a more difficult task than looking for an excellent couch that would complement your living room. This is because you have to consider a lot of factors, and making a single mistake can be very costly – well, for your wallet, of course. So you avoid messing up and wasting money on such errors, the following are things to look for when buying the perfect cooling mattress topper:

  • Measurement

Finding the right measurement doesn’t mean it has to be the ideal snug fit for your mattress. It still depends on what cover you are using for your cooling mattress topper. Some products have slightly lower measurements compared to standard sizes to give some allowance for several mattress cover designs.

  • Thickness

They say size doesn’t matter. This is particularly true considering different types of sleepers have different needs, most notably when it comes to thickness. Back sleepers are well suited for thinner cushions because it facilitates proper positioning of their spine during sleep compared to lying against a thicker pad. If you’re a back sleeper, you should check first hand on how thick you want your mattress topper to be.

  • Cooling and Breathability

Breathability refers to the ability of the mattress topper to promote airflow through its pores including its core. This also applies to the same ability exhibited by their cover. To facilitate efficient ventilation, both the foam and the cover must be able to promote sufficient airflow. Otherwise, there will be too much body heat trapped within. When this happens, the surface will never cool off, and this will ultimately lead to discomfort for the sleeper.

Some mattress toppers are specially designed to have temperature-regulating cores that further assist in the cooling process. They absorb heat and neutralize the warmth with cooling gel infusion distributed within the specialized foam.

Getting an efficient cooling mattress topper that never stays warm is an essential factor in deciding whether or not you’d stick with it or not. However, this is a hands-on experience that you’ll determine after some time of use and not something you’d discover in an instant. In case you rolled the losing end of the dice, at least you’d gain the experience not to repeat the same mistake.

  • Durability vs. Comfort

The type of mattress topper foam determines its durability. Latex foams are more durable due to their elastic nature, but they aren’t as soft and comfy as memory foams. On the other hand, the latter isn’t as permanent as the former as they are prone to tearing. It is crucial to weigh in on what is heavier on your priority list.

  • Special Features and Deals

Some cooling mattress toppers have unique features and deals that set them apart from their competitors. These can include additional items included in the purchase, such as a matching cover and even a matching cooling mattress pad. Depending on the price and overall quality, these bonuses can be hard to pass up and offer a better deal compared to purchasing the same items as separate purchases.

  • Warranty

A company that offers money-back guarantees and warranty periods means that they are confident with their products. The higher the warranty and return period, the higher the confidence that the company has. It is always a wise decision to go for a product that offers money-back or warranty periods because this puts you at a favorable advantage as a consumer.

If you are unsatisfied with the product, you can return it and get your money back as long as you do it within a limited time frame. Think of it as a trial period. You may not get your money back when it comes to warranty, but you do get a replacement. Either way, it’s a win-win situation for you.

Frequently Asked Questions

  • Why do cooling mattress toppers have a foul smell after opening it from their sealed package?

Off-gassing is typical to foam materials such as memory foams. It is a chemical reaction when volatile organic compounds, abbreviated as VOCs, break apart and form a gas that smells like industrial odor. Sometimes the scent can be so bad to other people with a more sensitive sense of smell that they can detect it.

  • Is off-gassing found in memory foams harmful?

These products are regulated for safety before being allowed to be sold in the market. Furthermore, off-gassing is a common phenomenon found in several household and office items such as dryer sheets, laser printers, and non-stick pans. Like those found in foam products, they usually don’t contain enough chemicals to cause harm to your body, and they dissipate after a short time.

The chemicals that cause mattress off-gassing may be classified as carcinogens, but there is no conclusive evidence that they are linked to cancer due to exposure to these chemicals. However, it doesn’t mean that people should be complacent and not reduce their exposure to this undesirable odor.

  • How can we get rid of this odor caused by off-gassing?

It naturally dissipates after some time, but opening windows and using fans to blow the smell away from the source helps speed up the process of getting rid of the undesirable smell.

  • Can we wash memory foam when it gets dirty?

Cleaning memory foam can be a daunting task due to its tendency to trap absorb and trap liquid and moisture, but it’s not outside the realm of possibility. It is still possible to wash it using gentle, natural solutions that won’t damage the foam’s delicate structure. Spraying the foam with a solution of one part mild laundry detergent and two parts warm water can do the trick. Do not soak the foam, but be sure to spray the entire thing lightly while keeping the spray bottle moving.


For what it’s worth, cooling mattress toppers offer a necessary upgrade to those who find their current mattress lacking but also find it wasteful to buy a new mattress just to replace the current one that still works fine and doesn’t have any damage. Under several circumstances, they serve as necessities rather than luxuries.

They help promote a conducive environment for sleep and aid in proper body mechanics while sleeping, preventing sore spots in the body when waking up the next day. They also protect the very mattress they lay on top of. For all the added costs you invest in your sleeping comfort, it’s a purchase that’s worth every penny.
