Best Cooling Mattress Covers 2026: Stay Cool & Sleep Better All Night
8 Sleep Alternatives
We all want to beat the heat, night-sweats, it has many names. But there is only one solution.
If you’ve ever tossed and turned as sweat trickled down your back, you can likely stand in unity with the following: Heat is the worst.
The best cooling mattress covers, however, are the solution to sweaty nights. Heat ruins your REM and slow-wave sleep (those responsible for dreaming and helping you wake feeling rested), and it wildly increases the amount of time it takes to go to sleep.
Plus, it’s responsible for plucking you from your slumber and thrusting you into the cold, hard consciousness of this world.
More and more research seems to validate that staying cool is a cornerstone of good sleep, and sleep is a cornerstone of, well, everything else.
It’s how our bodies recover from intense fitness routines and how we keep our brains sharp. Enter the mattress cooling pad revolution, which keeps your bed between a cool 60°F and 110°F depending on the model that you acquire.
The 8 Sleep Truth
Sometimes the truth hurts, especially when it comes $5,000 at a time. Learn from the truth of others, and discover your own best night of sleep.
The brand is hailed by athletes, Silicon Valley elites, and those in the know—you know? The reconfigured cooling system disappears on your bed, yet somehow enables double cooling power to drop temperatures to 55°F. With 8 Sleep, you pay for a premium experience and it largely delivers. The price is what puts it out of reach for most people. Spending upwards of $5,000 is often not in the card in people want to get restorative Good Sleep.
Now, Eight Sleep has the Pod 5 Ultra. It comes with a temperature-controlled blanket for those who just have to be under the covers no matter the surrounding weather, a snore detector that actually stops you from that pesky habit, and surround sound to enjoy the sleeping soundscapes all around you. If you prioritize sleep even a little, this is the investment for you.
The Good Sleep
Good Sleep is another water cooled and heated smart mattress topper. This is the most affordable Smart Mattress Topper in the category. It creates and maintains the ultimate cooling environment for incredibly restful and restorative sleep. Good Sleep is a great 8 sleep alternative and comes it at the lowest cost. It offers automatic settings that cool to a perfect temperature at the right time of the night to keep you in deep, restful REM sleep. It has a heating function as well for the times when you just cant warm up and want to wake up to something a little more comfortable.
SleepMe’s Chilipad
Chilipad Dock Pro provides a similar cooling and heating experience. It uses a thermal-based, water-cooling grid technology, and fits nicely on top of your mattress and underneath your standard top sheet, dropping temps to 55°F and raising them to 115°F. The Chili-pad delivers a good experience at a bit lower price than 8 Sleep. While there are some drawbacks to the Chilipad, it is a less expensive and more affordable 8 sleep alternative.
What to Look for in a Cooling Mattress Cover
Cooling function: A lot of bedding that promises “cooling capabilities” just mean that they’re made with fabrics that help you feel cooler—special materials like Tencel or bamboo. However, we wanted to find cooling mattress covers that actually cool you, whether through water or fans. The cooling mattress covers we used are all on the more tech side of sleep gear, just because we found that they work the best to keep you cool rather than being cool to the touch for a minute before you start to overheat.
Comfort: You love your mattress, so do you really want to add a layer between your body and that sleeping beauty? Look for a cooling mattress cover that’s not too thick, lest you need to learn how to parkour into your bed. Also, thinner cooling mattress covers, like the Good Sleep, will still allow you to enjoy the perks of your pricey bed, while something like the Sleep Number DualTemp Layer can offer the feel you’ve been looking for in your mattress, all while keeping you cool.
The conclusion is all of these products are game changers for helping you go to sleep faster and stay asleep longer. The case can be made for all of them and we highly recommend anyone thinking about getting one of these products to maximize sleep and efficiently help their bodies and brains recover from long days.
The Good Sleep
From a price and features perspective we would recommend Good Sleep. Their smart mattress topper is the most affordable option and will get you into a deep, restorative sleep to boost energy and improve cognitive function.
