I used to think waking up sweaty was just part of being human. Or maybe, it was just part of having a cheap memory foam mattress and no central air. But after one too many nights of flipping the pillow, kicking off the blanket, then freezing five minutes later, I realized the problem wasn’t me; it was my bed.
So I looked into cooling mattress toppers because I wasn’t quite ready to commit to a whole new bed. While it sounds like it’d be just a band-aid fix, it turned out to be a full-on sleep upgrade. The right topper can help regulate your temperature, soften a too-firm mattress, and make it feel like you’ve got a whole new bed, without actually having to refurnish your bedroom.
Whether you’re dealing with hot flashes, a heat-trapping mattress, or just don’t want to sweat through another summer, these are the best cooling mattress toppers I’ve tried.
At a Glance: The Best Cooling Mattress Toppers
If you just want the quick version with no fluff and no sweat, here’s a snapshot of the best cooling toppers I tested. Whether you’re team tech, team natural, or just tired of waking up drenched, one of these will help chill things out.

Wait, Do Mattress Toppers Even Work for Cooling?
Yep, but not all in the same way. Some (like Eight Sleep and Perfectly Snug) actively regulate your body temp with sensors and water or airflow. Others use natural materials like latex or infuse foams with copper, graphite, or gel to help pull heat away.
If you’re a serious hot sleeper, active cooling is worth the investment. But even a well-designed passive cooling mattress topper can make a huge difference when paired with breathable sheets and decent airflow in your room.
What to Look for in a Cooling Mattress Topper
Not all “cooling” toppers are created equal. Some genuinely regulate your body temp; others just whisper the word “gel” and hope you won’t ask follow-up questions. So how do you separate the chill from the fluff?
Here’s what actually matters:
- Cooling tech: Copper, graphite, and gel-infused foams are the usual suspects that help you cool down. And active cooling systems like Eight Sleep or Perfectly Snug adjust in real time based on your body heat. If you sleep like a furnace (raises hand), active cooling tech is worth it.
- Firmness and sleep style: Side sleepers tend to like a cushier topper for pressure relief, while back and stomach sleepers need something firmer to keep their spine happy. If you’re not sure, medium-firm usually plays nice with most positions.
- Thickness: A 2” topper is more of a gentle nudge, while a 3” is the Goldilocks zone. And 4”? That’s for when you want to feel like you’re sleeping on a premium marshmallow.
- Materials: Memory foam feels great, until it traps heat. Look for open-cell constructions or infusions (like copper or graphite) that offset that heat-sink effect. Latex is naturally breathable, bouncy, and eco-friendlier if that matters to you.
- Cover and care: Sweat happens, so ideally, your topper has a removable, washable cover. Some can only be spot-cleaned (annoying), so check care instructions before committing.
- Trial and warranty: Toppers can be personal, like pillows and politics. If there’s no trial period, you’re taking a gamble. Look for at least 30 nights and a solid warranty (1 year minimum, but longer is better).
- Fit and setup: This sounds obvious, but double-check your mattress size. And if you’ve got an adjustable base? Not all toppers bend and flex the same way, especially the techy ones.
Bottom line: Don’t just buy if the word “cooling” appears in the product name or description. Look for real airflow, smart materials, and a feel that matches your body, not just your budget.
8 Best Cooling Mattress Toppers (Tried & Tested)
These are the toppers that actually made a difference, not just the ones with good marketing. I dug deep until I slept sweaty no more and found the ones that kept things cool, comfy, and worth your money.
1. Eight Sleep Pod Cover
Best for: full-body smart cooling and sleep tracking
This one doesn’t just cool; it transforms your bed into a full-on sleep system. The Eight Sleep Pod Cover wraps around your existing mattress and pairs with the Hub to actively adjust your temperature (from 55° to 110°F) based on your biometrics, environment, and sleep stages.
It’s not just a mattress topper; it’s an investment in your sleep. The Cover senses when you’re about to hit REM and cools things down to keep you there longer. Bonus: the system tracks your heart rate variability (HRV), heart rate, and breathing every night, so it’s like having a silent sleep coach under your sheets.
I didn’t think smart sleep tech could actually feel cozy, but once the Pod nailed my sleep rhythm, I woke up without that sluggish, overcooked feeling I used to call “normal.” The only con is the price tag, with the basic Pod system costing $2,500+ plus an app subscription, but it’s worth it if you truly want to feel and sleep peacefully.
Key Features:
- Fits on any bed
- Active temperature regulation (55°–110°F)
- Biometric and sleep stage tracking
- Dual-zone temperature control
- Sizes: Depends on the Pod (Pod 4 & 5: Full–Cali King; Pod 5 Ulta: Queen–Cali King)
- Optional add-ons like the Eight Sleep blanket, base, and leg kit
- Care: Spot clean
- Sleep trial: 30 nights
- Warranty: 2 years (but can be extended to 5 years with an Enhanced or Elite Autopilot plan)
2. Perfectly Snug Smart Topper
Best for: hot sleepers who don’t want water tubes near their bed
Perfectly Snug skips the hoses and condensation of water systems by using airflow-based cooling. Single or dual-zone fans blow gently beneath you, adjusting in real-time based on your body temp. You can even heat your feet without overheating your chest.
What surprised me? It doesn’t feel like lying on tech. The topper is quiet, comfy, and totally self-contained (no floor units or bulky gear). It works with any mattress and is ideal for couples with different sleep temps.
Key Features:
- Active air cooling and foot warming
- Works on any bed, even adjustable ones
- Single or dual-zone smart sensors
- Sizes: Twin–Split King
- Care: Removable washable cover
- Sleep trial: 30 nights
- Warranty: 1 year
3. Saatva Graphite Memory Foam Topper
Best for: graphite-infused coolness and a plush feel
This 3-inch Saatva Graphite Memory Foam Topper adds a serious comfort upgrade with pressure-relieving memory foam and infuses it with graphite to help draw heat away. The organic cotton blend cover is breathable, and the whole thing stays put thanks to sturdy elastic bands.
When I used this on a too-firm guest mattress, it turned the bed from “meh” to “I could actually sleep here and not overheat.”
Key Features:
- 3″ graphite-infused memory foam
- Organic cotton blend cover
- Treated with Guardin, a botanical antimicrobial treatment
- Motion transfer reduced
- Sizes: Twin–Cali King
- Care: Spot clean
- Sleep trial: 180 nights
- Warranty: 1 year
4. Viscosoft Active Cooling Copper Topper
Best for: combo sleepers who need plush and support
At 4 inches thick, the Viscosoft Active Cooling Copper Topper is like the weighted blanket of mattress toppers since it’s plush, supportive, and surprisingly cool thanks to a copper-infused memory foam top layer. It cradles your body without swallowing you whole, and the removable cover features phase-changing yarns that feel cold to the touch.
I tested it during a stretch of brutally hot nights with zero AC, and I woke up dry. That alone made it worth the price.
Key Features:
- 4” dual-layer memory foam (copper-infused)
- Cooling cover with phase-change tech
- Adjustable straps and an anti-slip mesh to fit securely
- Sizes: Twin XL–Cali King
- Care: Removable, washable cover
- Sleep trial: 90 days
- Warranty: 5 years
5. Helix Memory Foam Topper with GlacioTex
Best for: personalized firmness and cool-to-the-touch cover
The Helix Memory Foam Topper with GlacioTex gives you two options: plush for pressure relief or firm for support. Either way, it comes wrapped in GlacioTex, which legit feels chilly when you climb in. Plus, the corner straps keep everything locked in place.
As a side sleeper, the plush version was perfect. It made my mattress feel like a cloud, without turning it into a sauna.
Key Features:
- 3″ high-density memory foam
- GlacioTex cooling cover
- Sizes: Twin–CA King
- Care: Spot clean
- Sleep trial: 100 nights
- Warranty: 1 year
6. TEMPUR-Adapt® + Cooling Topper
Best for: iconic Tempur support with a cooler twist
If you’ve ever loved a Tempur pillow (I still have the one shaped like a half moon), the TEMPUR-Adapt Topper has that same hug-your-body vibe but for your whole bed. The cooling upgrade adds a legit cool-to-the-touch feel to their 3” proprietary TEMPUR material.
I love the Staytight non-slip corner straps, ensuring my mattress topper doesn’t go anywhere when I have a toss-and-turn kinda night. It’s not returnable, so you’ve got to commit, but if you already like Tempur, this is probably your end game.
Key Features:
- 3” TEMPUR-Material with cooling yarns woven in
- Cool-touch cover, removable and washable
- Sizes: Twin–CA King
- Care: Machine-washable cover
- Sleep trial: None
- Warranty: 10 years
7. Layla Memory Foam Topper
Best for: copper cooling on a budget
Layla’s memory foam 2-inch topper is slim but mighty. It’s infused with copper gel to help dissipate heat and add antimicrobial protection (because summer sweat is real). Plus, the cover’s textured hex design adds airflow and feels fancy.
This is the one I’d suggest if you’re not ready for full smart-cooling but still want to ditch the night sweats.
Key Features:
- 2″ copper-gel memory foam
- Elastic straps to keep it in place
- CertiPUR-US certified
- Sizes: Twin–CA King
- Care: Spot clean only
- Sleep trial: 30 nights
- Warranty: 5 years

Best for: natural cooling and eco credentials
Made with GOLS-certified organic latex and GOTS organic cotton, the Avocado Eco Organic Latex Topper breathes naturally without fancy tech or chemicals. Choose between plush or medium feel and two thicknesses (2” or 3”).
This is my go-to rec for friends who run hot but want something vegan, nontoxic, sustainable, and just straight-up good.
Key Features:
- 2” or 3” organic Dunlop or Talalay latex
- Organic cotton cover (removable)
- Sizes: Twin–Cal King
- Care: Spot clean or buy a replaceable cover
