Is it even summer?

With summer in full swing, you may notice that you feel the hottest at night. Instead of raising your electric bill by lowering your thermostat, opt for the best cooling mattress topper on the market. Now, before you go on and add one to your cart, know that what's best for us, your friends, or even reviewers may not be best for you. For instance, you may prioritize a topper made with sustainable materials, while we could be more focused on the science behind the cooling factor. No matter what you're looking for, though, you'll definitely find a great option here.

We've included everything from pillow top mattress pads to memory foam alternatives (and everything in between), and though they're all pretty different, the one thing they have in common is their ability to cool you down—no matter how high the outside temperatures rise. We do just want to preface our picks by saying that only a few of them cost under $100 because a great cooling mattress topper is a niche product that often doesn't come cheap. That said, there is one promising pick that's only $70. Otherwise, go all out and snag what we'd consider to be the best version of a bedding essential—especially if you live in a city in the middle of a history-making heatwave.

The great thing about cooling mattress toppers is that you don’t need to replace them when the temperatures finally start to drop because the technology that makes them feel chilled in the summer will also bring the heat in the winter. It's called temperature-regulating technology, and we're all for it. Intrigued? Keep scrolling.

The first thing you'll notice about this cooling mattress topper is how comfortable it is thanks to the three-inch-thick layer of memory foam. After spending some time in bed, you'll quickly realize that it also feels cool to the touch. How, you might ask? It's infused with cooling graphite. Because it's made of thick memory foam, it reduces motion transfer, so if you toss and turn, your partner will be able to sleep through it. The topper is also covered in naturally breathable and moisture-wicking organic cotton that's finished with an antimicrobial treatment.

Cooling Materials: Graphite

Sizes: Twin, twin XL, full, queen, king, California king, split king

Sleep Trial: 180 days

We're not entirely sure why this best-selling Tempur-Pedic find is on a retailer marketed to teens (as opposed to everyone) because it's so good. The brand didn't exactly spill the beans about what's making the topper feel cool, but one thing we do know is that it's in the fabric cover, not the filling. It's also dust mite and allergen resistant and machine washable. Plus, because Tempur-Pedic was one of the first brands to jump on the memory foam bandwagon, this topper features the brand's unique technology that reduces motion transfer and relieves sometimes painful pressure points.

Cooling Materials: Fabric cover

Sizes: Twin, twin XL, full, queen, king

Here's the thing: There's an implication of basic when we're talking about a "core" product, but SlumberCloud's mattress pad is next level. It utilizes not one but two layers of NASA-approved temperature-regulating technology (it's called Outlast) that regulates body temperature by absorbing heat when you're hot and releasing it back into the fabric when you're cold. Spacesuits do the same thing! There are also more than 2,000 five-star reviews praising this thing.

Cooling Materials: NASA-approved temperature regulating technology

Sizes: Twin, twin XL, full, queen, king, California king, split king

Sleep Trial: 60 days

This is a memory foam mattress topper that's almost hard to compete with because it's as good as advertised. It features three inches of plush foam infused with cooling gel that captures and distributes heat. So if you've ever rolled away from the spot you've fallen asleep on to notice your new area is much colder (and much nicer feeling), this topper will be a game-changer. Extra support to relieve pressure points and prevent sinking makes it even cozier.

Cooling Materials: Cooling gel

Sizes: Twin, twin XL, full, queen, king, California king

Available in two- or three-inch thicknesses, the Allswell cooling memory foam mattress topper is worth the investment. This cushy topper is infused with gel that utilizes cooling technology (dubbed Coolflow) that promotes airflow and transfers heat away from your body. It also contains naturally cooling graphite that makes it feel cold even when you're not in bed.

Cooling Materials: Coolflow gel, graphite

Sizes: Twin, twin XL, full, queen, king

This West Elm waterproof mattress pad is filled with moisture-wicking Tencel, a textile made from cellulose aka plant fiber. So if you're a sleep sweater, this is a good find. Did we mention that it's hypoallergenic? As for the cooling aspects, the brand is keeping that under wraps, but it is cold to the touch.

Cooling Materials: Tencel lyocell fibers

Sizes: Twin, full, queen, king, California king

If you're looking to save, this Buffy pick is a good option because the brand is currently having a 20 percent off sale. Hurry, though, because it's starting to sell out! The twin size is already gone. It's covered in the super-soft signature fabric and filled with layers of recycled fibers that will give your mattress a more snuggly feel. The cover also absorbs moisture more efficiently than cotton does, which keeps you feeling cool and dry throughout the night.

Cooling Materials: Tencel lyocell fibers

Sizes: Twin XL, full, queen, king, California king

Sleep Trial: 7 days

This isn't the thickest mattress pad on our list, but it's definitely one of the most comfortable because it's filled with down-alternative Hydrocool, which is patented by Pottery Barn. The shell wicks away moisture while you sleep, which will make you feel cool and dry. To finish it off, the pad is wrapped in smooth hypoallergenic cotton.

This mattress topper is as comfortable as it is cooling, courtesy of the dual-layer design. The bottom layer comprises a gel memory foam that offers pressure-relieving body support, and the top layer is a cool-touch fiberfill cover. It's also machine washable and antimicrobial, so you should never see mold or mildew.

The thing about all things mattresses is you won't really know how much you like it (or don't like it) until you try it, so our advice is to do some research, read some reviews, and make a purchase that feels best for you. If you aren't entirely sure, be sure to snag one with a free sleep trial so that you can experience them first-hand before committing. The longer the trial period, the better. Be sure to check whether there are any fees (such as shipping or restocking) associated with a return during or at the end of the trial period too.

If you want to keep your bed cool while you sleep, don't stop at a cooling mattress topper! Go with cooling sheets, temperature-regulating pillows, and even a cooling mattress. There's really no limit to how far you can go when it comes to making your sleep sanctuary a chilled oasis.

When it comes to singling out the best cooling mattress topper, we've done our due diligence. All of our picks are relatively affordable (for what you're getting) and actually work, so whether you're on the hunt for something that's sustainably made or features top-of-the-line technology, you'll find it here.
