How to Decide on a Cooling Mattress Topper
A popular type of mattress topper is a “cooling” one. That means it helps keep your body at a comfortable temperature while lying on top of it, which is important for those who often get hot while asleep.
This change in internal temperature can wake you up, interrupt a deep sleep, and leave you tired and groggy the next day. With a cooling top layer over the mattress, some people can enjoy a longer, better sleep. That’s why features to cool the body are a must for the best cooling mattress topper for those who sleep hot.
The ideal topper will have specific features to help you avoid overheating while falling asleep and while in a deep sleep, minimizing the chances of waking up before it’s time to get out of bed. In addition to the cooling features, top considerations include the fabric and sleep trial.

Our Pick for Best Cooling Mattress Topper: Saatva Graphite Memory Foam Topper
With several different models available, knowing which one to choose can be challenging. After careful consideration, we consider the American-made Saatva Graphite Memory Foam Topper a top choice for those who want a cooler sleep. Let’s look at why.
Excellent at Cooling
This feature is the main reason shoppers who get uncomfortably warm sleeping will appreciate this topper. Saatva’s graphite memory foam topper goes over the existing mattress to provide a superior cooling experience at a reasonable price point.
The key is the graphite material. Graphite excels at whisking moisture away from the body, which is why we love that Saatva infused it within the memory foam in this topper. With small pores, graphite absorbs heat very well, often better than other materials used for cooling.
Moreover, the topper is made of breathable cotton, which is naturally breathable and wicks away moisture. That means it won’t retain heat or pool body sweat.
This thoughtful design encourages better sleep for those who might otherwise wake up unexpectedly because they are sweating. There are other benefits, too.
Plush but Not Hot
Besides being comfortable on a cooler surface, many people will likely appreciate the best cooling mattress topper from Saatva, which feels luxurious while lying on it. Although you might associate plush with being hot, that’s not likely to be the case, given the cooling properties of the graphite material, as mentioned earlier.
The soft feel comes from the 3-inch layer of memory foam in the Saatva Graphite Memory Foam Topper. Along with the cushiony feel, this material offers pressure-relieving support for some sleepers. The feel is like a welcome “hug” while sleeping, supporting the body’s curves.
Thus, the plush topper helps increase the comfort of your existing mattress without risking a hotter sleep environment. It is infused with cooling graphite and breathable cotton, improving the feeling of being comfy and relaxed, which may help drifting off to sleep.
Healthier for the Planet and You
We also like Saatva’s eco-friendly approach with the Graphite Memory Foam Topper. The foam is made from renewable oils, and less greenhouse gases are produced during manufacturing.
The foam is CertiPUR-US® certified, which means it is low in VOCs (volatile organic compounds). This limits unpleasant off-gassing odors from the topper and guarantees that it does not contain mercury, lead, other heavy metals, ozone depleters, and more.
In addition to being good for the planet, it’s also highly resistant to bacteria, mildew, and mold. Saatva uses a special Guardin™ botanical antimicrobial treatment to achieve this. Thus, it’s a healthier pick for you, your home, and the planet.
Less Motion Transfer
The memory foam is 3-inch thick, which helps reduce motion transfer. That refers to movement across the bed when a sleeper moves.
In addition to being the best cooling mattress topper, it’s a bonus that the other person in the bed is less likely to feel motion and wake up when their sleeping partner moves during the night. That helps make for a more restful sleep.
Long Trial Period
Before making a purchase, you might ask yourself, but is it right for me? Only you can know that but being able to try out the Saatva Graphite Memory Foam Mattress Topper at home for a long 180-night trial period can help you decide.
This long home trial period means that you have several months from the delivery date to decide if you want to keep the topper. Saatva stands behind its product by providing this great feature and a one-year limited warranty.
Great Fit
If you wonder if this topper will fit your mattress, Saatva’s website explains that it works with any of their mattresses and other mattress brands.
It comes in the most popular mattress sizes, too:
- Twin
- Twin XL
- Full
- Queen
- King

When it comes to any messes on the topper, Saatva’s website suggests using a mild cleaner to spot-clean them.
