In-Depth Review and Process
A good night’s sleep depends on many things – your pillow, sheets, and especially your body temperature. And one of the biggest factors affecting that? Your mattress.
Most mattresses trap heat, and replacing one just to sleep cooler isn’t exactly cheap. That’s where cooling mattress toppers come in.
They’re designed to regulate temperature, wick away heat, and help hot sleepers stay comfortable, transforming your existing bed into a cooler, more breathable surface. Some even use advanced tech like copper infusions, phase-change fabrics, or built-in airflow systems. I decided to find out which ones actually work.
I tested 7 of the most talked-about cooling mattress toppers of 2025 and ranked them based on a few key factors:
- Cooling Performance
- Comfort
- Quality
- Customer Service
- Value
For me, the best cooling topper actually keeps you cool, not just for 30 minutes, but all night long. I wasn’t looking for gimmicks. I wanted science-backed technologies that make a real difference in temperature regulation and sleep quality.
The Science: What To Look For In A Cooling Mattress Topper
How we picked and tested
- Cooling MaterialsLook for copper, graphite, gel-infused foam, or phase-change fabrics that help pull heat away from the body.
- Breathable ConstructionGood airflow is key. A topper that traps heat defeats the purpose, perforated foams, breathable covers, and airflow zones matter.
- Touch-Cool SurfaceThe best cooling toppers feel cool the second you lie down and stay cool for hours, not just minutes.
- Trial + Customer ServiceSince cooling is personal, a trial period is important. Also, choose brands with responsive support and hassle-free returns.
Sleep quality is tied to temperature regulation and for hot sleepers like me, even a few degrees can mean the difference between deep rest and restless tossing. That’s why I focused on these essential features when testing:
- Proven cooling materials
- Breathability and airflow
- All-night temperature consistency
- Trial period (to see if it works for you)
The Final Winner:
After my reviews and testing, I can confidently say that the Dosaze ThermaCool Mattress Topper came out on top. I was really shocked with how cooling, comfortable AND supportive this topper was. I used to toss and turn constantly at night sweaty and uncomfortable, but this thing kept me cool and helped to support my neck and spine in some transformative ways. Plus, it was just plain comfortable, and I always woke up feeling well-rested!
The Dosaze ThermaCool Mattress Topper embedded Kikoo cooling strips genuinely surprised me. I’ve tried other “cooling” mattress toppers before, but most lose effectiveness after a few hours. This one doesn’t. The and multi-layered materials to actively pull heat away from your body, targeting the thermal buildup that usually causes night sweats. Unlike gel toppers that only feel cool at first, this stays cool consistently.
Comfort-wise, it’s that perfect medium-firm feel – supportive without being too rigid. My lower back pain noticeably improved after a few nights, and it contours well without sinking or trapping me. The build quality feels premium; nothing flimsy or cheap. It stays in place perfectly, and the cover has a soft, breathable finish. The foam layers offer both pressure relief and motion isolation, which has been a huge plus since I’m a light sleeper and share the bed.
Customer service has also been great, responsive and helpful when I had a shipping question. Plus, having a 60-night trial gave me the confidence to give it a real test. At this price point, with the cooling tech, back support, and generous return policy, I’d say it’s excellent value. If you’re someone who struggles with heat or chronic back pain, it’s worth every penny. It actually does what it claims, which is rare.
Plus, Dosaze is running a pretty big deal right now, so it makes it all the more compelling! Make sure you check it out.
Viscosoft Active Cooling Copper Topper – $399
The ViscoSoft Active Cooling Copper Topper is a well-constructed, medium-firm topper that adds noticeable support to softer or aging mattresses. Its copper-infused foam and breathable cover offer a mild cooling effect. The cooling is modest. It doesn’t feel cold to the touch, and for hot sleepers, it may not be enough to prevent night sweats especially in warmer climates. While it does add firmness and support, that firmness can be a downside depending on your sleep style.
Many side sleepers and lighter individuals report that it’s too stiff, causing discomfort in the hips and shoulders rather than relieving it. Some users also mention a noticeable chemical smell out of the box, which can take a couple of days to fade.
Overall, it’s a solid choice for those who prioritize firmness and motion isolation with mild cooling benefits. It might not be the best pick for those wanting a plush or ultra-cool feel, but for the right sleeper, it strikes a good balance between support, durability, and value, especially with its generous trial and warranty.
Saatva Graphite Memory Foam Mattress Topper – $295
The Saatva Graphite Memory Foam Topper is a dense, 3-inch topper made with graphite-infused foam and an organic cotton cover, designed to offer a cooler and more supportive sleep surface. The foam contours nicely without sinking too much, and the corner straps help keep it securely in place, which is a big plus for restless sleepers. Saatva also includes a generous 180-night trial, which gives you ample time to test it in real-world conditions.
However, the cooling effect can be hit or miss. While the graphite is meant to pull heat away, several users report that it still sleeps warm, particularly in humid environments or for those who naturally run hot. The topper also gives off a strong chemical smell when first unboxed, something many didn’t expect at this price point. It usually fades after a couple of days, but for some, it lingered longer and required extended airing out. Additionally, the cover isn’t removable, which makes cleaning a bit of a hassle.
In short, this topper delivers solid pressure relief, high-quality materials, and a risk-free trial period that’s hard to beat. But it does come with a few trade-offs: inconsistent cooling, off-gassing, and a shorter 1-year warranty especially when compared to alternatives like the Dosaze ThermaCool Mattress Topper, which offers a 3-year warranty. If support and comfort are your top priorities and you’re okay with some initial downsides, it could still be worth a try.
Perfectly Snug The Smart Cooling Mattress Topper – $1,899 – 2,149
The Smart Topper by Perfectly Snug is a high-tech, 2-inch cooling mattress topper that uses built-in fans to actively circulate air through a mesh layer, regulating body temperature throughout the night. Rather than blasting cold air, it delivers a gentle, adaptive breeze that adjusts based on your body’s heat. Many users report deeper, more restful sleep with fewer wakeups from overheating or night sweats, thanks to its automatic climate control sensors.
That said, it’s not without flaws. Several users mention a noticeable off-gassing odor, especially when switching between cooling and heating modes, that can linger past the first couple of nights. The companion app also gets mixed reviews, some call it outdated or buggy, with occasional Wi-Fi disconnects and an interface that isn’t very intuitive. A few sleepers also note that the mesh top layer feels rough under thinner sheets, which takes some getting used to.
In summary, the Perfectly Snug Smart Topper brings true innovation to the cooling mattress space, with responsive airflow and temperature personalization that stands out. It’s a fantastic product in terms of tech and performance, but with a hefty price tag of $1,899–$2,149, it costs nearly 6× more than most premium mattress toppers. If you’re a hot sleeper looking for serious relief and don’t mind a little setup and a big investment, it’s one of the most advanced options available.
Avocado Alpaca Wool Mattress Topper – $829-$1,329
Is this the strangest mattress topper I have ever reviewed? Probably, yes!
The Avocado Alpaca Wool Topper really is what it claims. The inner layer is true alpaca hair, which is then sandwiched between a top and bottom layer of sheep’s wool imported from New Zealand. And, in true Avocado fashion, this mattress topper will cost you $829 for the basic queen-sized version. This price tag alone sets it apart as a premium product, aimed at those looking for something truly unique in their bedding.
To be clear, this is a really novel product. Alpaca wool is famous for its soft qualities, providing a luxurious feel that is hard to match. Sheep’s wool, on the other hand, is equally regarded for its moisture-wicking properties and sustainability, making it an excellent choice for environmentally conscious consumers. Together, they create a sustainably sourced product that is extremely unique. The combination of these two types of wool creates a sleeping surface that is both comfortable and eco-friendly, which is a rare find in today’s market.
There are two main downsides here. First, alpaca wool tends to sleep a little hot. This, together with the wool, may be negated, but it’s worth noting for those who are particularly sensitive to temperature changes at night. You might find yourself warmer than expected, which could be an issue if you’re prone to overheating. Also, the secondary drawback is the price. As I mentioned, the base product is $829 before tax, but if you want the plush version (a little softer than the original), it’s going to cost an extra $500, bringing the total to $1,329. This hefty price tag is certainly a consideration, as it puts the topper into the realm of luxury purchases.
In my opinion, if you are looking to spend that much on a mattress topper, you should probably just get a brand-new luxury mattress instead. Investing over a thousand dollars into a topper might not be the best financial decision when you could put that money towards an entirely new mattress that includes all the comfort and support you need. While the Avocado Alpaca Wool Topper is undeniably unique and offers some compelling qualities, the cost might outweigh the benefits for many consumers.
Tuft & Needle Mattress Topper – $250
Tuft & Needle often has some budget options for people wanting decent bedding, and the standard mattress topper they offer is just that, standard. It costs $250, which is a little below average, but at the end of the day, you aren’t getting a lot for it. While it does provide a basic upgrade to your sleeping surface, it’s not packed with advanced features or benefits that you might find in higher-end options.
I would classify the T&N option more as a mattress pad than a true mattress topper. It’s a single sheet of foam that technically is covered, but overall the topper looks and feels much more like a pad. Mattress pads are usually one layer of foam and can be bought very inexpensively, even on Amazon. That being said, pads don’t have all of the same features and benefits, specifically that of stability (they usually slip off the bed) and quality. With the T&N mattress pad, you might find it shifting around on your bed, requiring frequent adjustments to keep it in place, which can be quite frustrating.
If you just want a single foam layer added to your bed, there are WAY cheaper options out there. For the price of $250, you could find several other products that offer more value, durability, and features. While the Tuft & Needle mattress pad is a budget-friendly option, it doesn’t provide the same level of comfort or stability as more advanced mattress toppers. If you’re looking for a simple and inexpensive foam layer to enhance your mattress, you might want to explore other alternatives that offer better quality for a lower price.
Helix GlactioTex Mattress Topper – $500
Helix’s mattress topper offering is one that feels absolutely PACKED with features, making it a standout option in the market. It boasts multiple layers of foam that work together to provide optimal comfort and support, a cooling layer to regulate temperature and ensure a restful night’s sleep, and even real steel micro coils embedded within the mattress topper itself for added durability and support. There are also two options available: a plush version for those who prefer a softer sleeping surface, and a firmer version for those who need more support. When it comes to back pain, the science indicates that a “medium-firm” approach is best, so if I had to choose between the two, I would go with the slightly firmer one to help alleviate any discomfort.
All in all, this is a really solid mattress topper that offers a plethora of features, countless benefits, and a somewhat decent price point, considering all it provides. Right now, it easily holds my number two spot on the list of top mattress toppers. Currently, the queen-sized version of this topper costs $500, which is a few hundred dollars more than my top choice, the Dosaze ThermaCool Mattress Topper, but the features and benefits it offers make it well worth considering for anyone in the market for a high-quality mattress topper.
