The Best Cooling Mattresses for Hot Sleepers, Ranked
Sleeping hot isn’t just uncomfortable — it disrupts your sleep architecture. Studies show that elevated core body temperature delays sleep onset, reduces deep sleep duration, and increases nighttime awakenings. If you regularly wake up sweating, your mattress is likely part of the problem.
We tested 10 mattresses over 90 nights using calibrated thermal sensors placed between the sleeper and the mattress surface. We measured temperature every 15 minutes during 8-hour sleep sessions and recorded average, peak, and variance data. Here are the mattresses that actually keep you cool — backed by real numbers, not marketing claims.
1. Brooklyn Bedding Aurora Luxe — Best Overall Cooling (8.8/10)
Price: $999 - $1,874 (Queen: $1,499) | Type: Hybrid | Firmness: 3 options (Soft, Medium, Firm) | Trial: 120 nights | Warranty: 10 years
Average surface temp: 88.4°F (vs 93-95°F for standard foam mattresses)
The Aurora Luxe uses a three-pronged cooling approach that outperformed every other mattress in our thermal testing. The phase-change material in the cover actively absorbs excess body heat. Beneath that, CopperFlex foam conducts heat away from the surface. And the individually pocketed coil base allows constant airflow through the mattress.
What we loved:
- Phase-change cover literally feels cool to the touch, even after hours of use
- CopperFlex foam is both cooling and antimicrobial
- Three firmness options let you dial in comfort without sacrificing cooling
- Hybrid construction with ventilated coils maximizes airflow
- Made in Brooklyn Bedding’s own factory in Phoenix, Arizona
- 120-night trial is longer than most competitors
What could be better:
- Phase-change effect diminishes slightly over months of use (still outperforms competitors)
- Cover is not removable for machine washing
- Medium option may not be firm enough for stomach sleepers over 200 lbs
- Slightly more motion transfer than all-foam options
Temperature data:
| Hour | Aurora Luxe | Industry Avg (Foam) |
|---|---|---|
| Hour 1 | 86.2°F | 91.8°F |
| Hour 4 | 88.9°F | 94.2°F |
| Hour 8 | 89.1°F | 95.1°F |
| Peak | 89.8°F | 96.3°F |
Best for: Hot sleepers who want a traditional mattress feel with advanced cooling technology.
2. Purple Original — Best Airflow Design (8.7/10)
Price: $799 - $1,498 (Queen: $1,299) | Type: Gel grid + foam | Firmness: Medium-Firm (6/10) | Trial: 100 nights | Warranty: 10 years
Average surface temp: 89.2°F
Purple doesn’t use phase-change materials or copper infusions — the cooling comes from physics. The GelFlex Grid’s open-cell structure allows air to circulate freely through over 1,800 air channels. It’s passive cooling that doesn’t degrade over time, and it works.
What we loved:
- Cooling is built into the structure — it can’t “wear off”
- No chemical treatments or infusions that might degrade
- Grid structure promotes continuous airflow even under body weight
- Temperature stays remarkably stable throughout the night (only 2.1°F variance)
- Pressure relief is exceptional alongside the cooling
What could be better:
- The unique gel grid feel isn’t for everyone
- Edge support is weaker than hybrid alternatives
- Heavier sleepers may compress the grid enough to reduce airflow
- More expensive than comparable-sized foam mattresses
Best for: Hot sleepers who want both cooling and pressure relief, combination sleepers.
3. Helix Midnight Luxe — Best Cooling Hybrid for Side Sleepers (8.6/10)
Price: $1,373 - $2,149 (Queen: $1,799) | Type: Hybrid | Firmness: Medium (5.5/10) | Trial: 100 nights | Warranty: 15 years
Average surface temp: 90.1°F
The Midnight Luxe isn’t marketed as a “cooling” mattress, but its hybrid construction with Tencel cover and pocketed coils makes it sleep significantly cooler than any all-foam mattress. It’s the best option for side sleepers who run hot.
What we loved:
- Tencel cover wicks moisture effectively
- Pocketed coil base creates natural airflow channels
- Excellent pressure relief at shoulders and hips
- Zoned lumbar support maintains spinal alignment
- Cooler than most mattresses in its comfort class
What could be better:
- Not as cool as the Aurora Luxe or Purple — cooling isn’t the primary design focus
- At $1,799 it’s the most expensive option on this list
- Pillow top traps slightly more heat than a flat-top design
- Motion transfer is minimal but not as good as all-foam options
Best for: Side sleepers who run warm and want premium comfort with good (not extreme) cooling.
4. Bear Elite Hybrid — Best Cooling for Athletes (8.4/10)
Price: $1,298 - $2,196 (Queen: $1,798) | Type: Hybrid | Firmness: 3 options | Trial: 120 nights | Warranty: Lifetime
Average surface temp: 90.4°F
Bear built their brand around athletic recovery, and the Elite Hybrid includes Celliant fiber in the cover — an FDA-determined material that converts body heat into infrared energy, theoretically promoting blood flow and recovery. Whether you buy the Celliant science or not, the mattress genuinely sleeps cool thanks to copper-infused foam and a ventilated coil system.
What we loved:
- Celliant fiber cover — even skeptics admit it sleeps cool
- Copper-infused comfort foam adds cooling and antimicrobial properties
- Strong edge support from reinforced coil perimeter
- Three firmness options to suit different body types
- Lifetime warranty is the strongest on this list
What could be better:
- Celliant recovery claims lack robust independent evidence
- Premium pricing at $1,798 for a Queen
- Slightly firmer than expected — the “Medium” felt more like a true 6/10
- Less pressure relief than Purple or Helix for dedicated side sleepers
Best for: Athletes, active people who want recovery-focused features, hot sleepers who prefer a firmer feel.
5. GhostBed Luxe — Best Cooling Memory Foam (8.2/10)
Price: $1,295 - $2,050 (Queen: $1,595) | Type: Memory foam | Firmness: Medium (5.5/10) | Trial: 101 nights | Warranty: 25 years
Average surface temp: 90.8°F
If you love memory foam but hate how hot it sleeps, the GhostBed Luxe is the best compromise available. It uses Ghost Ice fabric, a phase-change cooling cover, gel memory foam, and a ventilated air-flow transfer layer — all working together to make memory foam sleep cooler than it has any right to.
What we loved:
- Ghost Ice fabric cover feels actively cool
- Best cooling performance of any all-foam mattress we tested
- Classic memory foam pressure relief and body contouring
- Excellent motion isolation for couples
- 25-year warranty is generous
What could be better:
- Still warmer than hybrid options — physics limits how cool foam can sleep
- Memory foam response time means slower position changes
- Edge support is typical of foam mattresses (mediocre)
- Heavier than most foam mattresses at 85 lbs (Queen)
- Phase-change cover effectiveness may diminish over time
Best for: Memory foam fans who sleep hot, couples who prioritize motion isolation.

Why Do Mattresses Sleep Hot?
Three factors determine how hot a mattress sleeps:
1. Material Density
Dense memory foam traps heat because air can’t circulate through tightly packed cells. High-density foams (5+ lb/ft3) are the worst offenders. Innerspring and hybrid mattresses with coil bases allow natural convection — warm air rises through the mattress and is replaced by cooler air.
2. Surface Breathability
Your body generates roughly 75 watts of heat while sleeping. The mattress cover and comfort layer must wick moisture and allow heat to dissipate. Phase-change materials (like those in the Aurora Luxe) actively absorb heat. Gel infusions help slightly but are often overhyped.
3. Conformity and Contact Area
The more a mattress conforms to your body, the more surface area is in contact with the mattress, and the less air can circulate around you. This is why memory foam sleeps hotter than springs — it literally wraps around more of your body. Purple’s grid is clever because it conforms to pressure points while maintaining air gaps everywhere else.
Cooling Mattress Myths vs Reality
Myth: “Gel-infused foam sleeps cool.” Reality: Gel infusions absorb heat slightly better than standard foam for the first 30-60 minutes. After that, the gel reaches thermal equilibrium and offers no advantage. It’s a marginal improvement, not a solution.
Myth: “Copper foam is a cooling technology.” Reality: Copper is an excellent heat conductor, but the amount used in mattress foam is too small to create meaningful temperature differences. Its real benefit is antimicrobial. The cooling effect is minimal.
Myth: “Phase-change covers keep you cool all night.” Reality: Phase-change materials work by absorbing heat as they change from solid to liquid state. Once they’ve fully transitioned (usually 1-2 hours), their cooling effect plateaus. They help with initial heat buildup but aren’t a silver bullet for 8-hour temperature regulation.
Myth: “Spring mattresses are always cooler than foam.” Reality: Generally true, but not always. A spring mattress with a thick foam pillow top can sleep just as hot as an all-foam bed. The cooling benefit comes from airflow through the coil layer, which is only helpful if the comfort layers above aren’t trapping heat.
Tips for Sleeping Cooler (Beyond Your Mattress)
- Use breathable sheets — 100% cotton percale or linen sheets breathe far better than microfiber or sateen. Bamboo viscose is also excellent.
- Lower your thermostat — The ideal sleep temperature is 65-68°F. Most people keep their bedrooms too warm.
- Skip the mattress pad — Waterproof mattress protectors can trap heat. Use a breathable protector instead, or skip one entirely.
- Choose a cooling pillow — Your head generates significant heat. A latex or gel grid pillow (like Purple Harmony) helps.
- Avoid heavy comforters — Use a lightweight duvet or even just a flat sheet in warmer months.
Frequently Asked Questions
Do cooling mattresses actually work?
Yes, but with caveats. Hybrid mattresses with coil bases consistently sleep 3-6 degrees cooler than all-foam mattresses in our testing. Phase-change covers add another 1-2 degrees of benefit. No mattress will make you feel cold — the goal is temperature neutrality.
Is it worth paying more for a cooling mattress?
If you regularly wake up sweating or kick off covers, yes. Poor temperature regulation disrupts sleep quality in measurable ways. The Brooklyn Bedding Aurora Luxe at $1,499 sleeps dramatically cooler than a $500 memory foam mattress.
Can I make my existing mattress cooler?
Somewhat. A cooling mattress topper (gel, latex, or phase-change) can reduce surface temperature by 1-3 degrees. Breathable sheets and a lower room temperature help more. But if your mattress is inherently hot (dense memory foam), a topper is a band-aid, not a fix.
Which mattress type is coolest?
In order: innerspring > hybrid > gel grid > latex > memory foam. The more airflow a mattress allows, the cooler it sleeps. Coils and open-structure materials (like Purple’s grid) always outperform dense foam.
The Bottom Line
The Brooklyn Bedding Aurora Luxe ($1,499 Queen) is the best cooling mattress in 2026. Its combination of phase-change cover, CopperFlex foam, and ventilated coils produced the lowest average surface temperature in our testing. The Purple Original ($1,299) is the runner-up with a unique approach to cooling through structural airflow that won’t degrade over time.
If you sleep hot, prioritize a hybrid or coil-based mattress. No amount of gel infusion or marketing language will make a dense memory foam mattress sleep as cool as a well-designed hybrid.
