Best Cooling Mattress for Hot Sleepers
Almost every mattress advertises cooling. Here is what actually moves heat away from your body, and what is just marketing.
A cooling mattress moves body heat away from you instead of trapping it, and the biggest factor is the support core, not the cover. A hybrid with a pocketed coil core will sleep cooler than an all foam bed of any kind, because air moves through the middle of the mattress. Latex and wool also handle heat well. If you want memory foam contouring, look for engineered cooling lines rather than standard foam with a gel infusion.
Sleeping hot is not just uncomfortable. Your core temperature needs to drop slightly for you to fall asleep and stay in deep sleep, and a mattress that traps heat works against that all night.
The good news is that cooling is one of the more solvable mattress problems, because the causes are mechanical. Heat gets trapped by materials that hold it and by surfaces that do not let air move.
Best Cooling Mattress by Category
-
Best Cooling Mattress OverallHelix Midnight Luxe
A coil core moves air the way a foam slab cannot, and the quilted cover keeps heat off the surface. The balanced medium feel means you are not sinking into a pocket of your own warmth.
-
Best Cooling Memory FoamTempur-Pedic Breeze
Tempur-Pedic measures the Breeze models at up to 10 degrees cooler at the surface than standard TEMPUR material. If you want memory foam contouring without the heat, this is the answer.
-
Best Cooling TechnologyPurple Hybrid Premier
The GelFlex Grid is an open column structure, so air moves through it continuously. Purple cites 2 to 4 times better heat dissipation than foam.
-
Best Cooling HybridBeautyrest Black
Pocketed coils plus cooling treated comfort layers. A traditional feel that does not trap heat the way an all foam bed will.
-
Best Natural CoolingAvocado Green Mattress
Organic latex over coils, with wool in the cover. Wool regulates temperature in both directions, and latex does not hold heat the way memory foam does.
Why Some Mattresses Sleep Hot
Three things drive it. Material, airflow, and how far you sink.
Traditional memory foam is dense and closed cell, so it holds body heat rather than releasing it. Then there is airflow: a solid foam slab has nowhere for warm air to go, while a coil core has open space through the middle of the mattress. Finally, the deeper you sink, the more of your body is surrounded by mattress rather than exposed to air.
Cooling Mattress Comparison: Hybrid vs. Latex vs. Memory Foam
| Type | Cooling | Why | Best for |
|---|---|---|---|
| Hybrid | Excellent | Coil core moves air through the middle of the mattress | Most hot sleepers |
| Latex | Very good | Open cell structure, does not hold heat, wool covers regulate temperature | Natural materials, hot sleepers who want responsiveness |
| Memory foam | Fair to good | Dense and closed cell, holds heat unless specifically engineered against it | Pressure relief first, cooling second |
| Cooling memory foam | Good | Phase change materials and gel infusions pull heat off the surface | Side sleepers who want contouring and run warm |
Mattress Types Ranked by Cooling Performance
- Latex hybrid. Coil airflow plus a material that does not hold heat.
- Coil hybrid with cooling cover. The most common good answer.
- Engineered cooling memory foam. Breeze and similar. Real cooling, still foam.
- Standard hybrid. Better than any all foam bed by default.
- Standard memory foam. The warmest common construction.
Does Firmness Affect How Cool You Sleep?
Yes, more than people expect. The further you sink, the more of your body is wrapped in mattress and the less is exposed to moving air. A softer bed of the same construction will sleep warmer than a firmer one for that reason alone.
This creates a real tension for side sleepers who run hot, because side sleeping needs a softer surface. The answer is usually a hybrid with a cooling treated comfort layer rather than compromising on firmness, which just trades one problem for another.
Not Sure Which Cooling Mattress Is Right for You?
BedMATCH narrows the floor to your comfort range in about three minutes, so you can compare cooling options that actually fit.
Best Mattress for Night Sweats
If you wake up damp rather than just warm, moisture management matters as much as heat. Look for covers with wool or Tencel rather than polyester, because they move moisture away from your skin instead of holding it.
A mattress protector can quietly undo all of this. Many waterproof protectors are effectively plastic sheeting, which blocks every bit of airflow the mattress was designed to provide. If you use one, use a breathable model.
Persistent night sweats can also have causes that have nothing to do with your mattress. If changing your sleep setup does not help, that is worth raising with your doctor.
How Mattress Cover Materials Affect Cooling
| Cover material | Cooling effect | Notes |
|---|---|---|
| Wool | Very good | Regulates in both directions, moves moisture, naturally flame resistant |
| Tencel or lyocell | Very good | Moves moisture well, feels cool to the touch |
| Phase change material | Excellent at first contact | Pulls heat off quickly, effect lessens as it saturates |
| Organic cotton | Good | Breathable, holds moisture more than wool |
| Polyester blends | Fair | Common on lower priced mattresses, traps heat and moisture |
Top 5 Cooling Mattress Features to Look For
- A coil support core. The single biggest factor.
- A breathable cover. Wool, Tencel, or phase change over polyester.
- Open cell or perforated comfort layers. Ask whether the foam is ventilated.
- Moderate sink. The less of you is surrounded by mattress, the cooler you sleep.
- Gel or graphite infusion. Helps, but it is the smallest of the five.
Cooling Beyond the Mattress
Your mattress is one part of the system. A breathable mattress protector, cooling pillows, and natural fiber sheets all matter. So does an adjustable base, which lifts the mattress off a solid platform and lets air move underneath it.

How We Chose
These picks come from 45 years of fitting Southern California sleepers, more than three million customers, and what we watch people choose after they lie down. For cooling we weight support core construction and cover material ahead of marketing claims about gel infusions, which make the smallest real difference.

Helix
Every Helix model is built on a wrapped coil core, which means airflow is designed in rather than added on. The Luxe tier adds a quilted cover that keeps heat off the surface.
Because Helix builds different models for different sleep positions, you can find a cooling option without compromising on the firmness your body actually needs. That is the main reason it works well for hot sleepers who sleep on their side.
A Wesper sleep tracking study of Helix owners reported 87 to 94 percent of participants saw improved sleep quality after switching.
Purple
The GelFlex Grid is an open column structure with air channels running through it in every direction. Nothing else on our floor moves air the way it does, and it is the closest thing to a mattress that actively vents.
Purple cites SleepScore Labs research reporting 2 to 4 times better heat dissipation than foam. In store, most people notice it within a couple of minutes.

Tempur-Pedic
Standard memory foam holds heat. The Breeze line is Tempur-Pedic's answer, combining a phase change cover with ventilated comfort layers, and they measure it at up to 10 degrees cooler at the surface than standard TEMPUR.
If you want the pressure relief of TEMPUR material and heat has been the reason you avoided memory foam, this is the line to test.
Beautyrest
Pocketed coils give you airflow through the core, and the World Class and Black lines pair that with cooling treated comfort layers and breathable covers.
If you want a familiar innerspring feel rather than foam or a grid, and you run warm, this is the most straightforward answer on the floor.
Avocado
Organic latex over pocketed coils, with wool and organic cotton in the cover. Wool is the most underrated cooling material in the category, because it regulates in both directions and moves moisture rather than holding it.
Latex also does not trap heat the way memory foam does. Combined with a coil core, it is one of the coolest constructions available.
Avocado holds an endorsement from the American Chiropractic Association and carries five organic and safety certifications including GOLS, GOTS, and GREENGUARD Gold.
Common Mistakes I See on the Sales Floor
Buying a cooling cover and calling it solved
The cover is the smallest lever. If the mattress underneath is a solid foam slab, a phase change cover buys you about twenty minutes of feeling cool at first contact and then you are back where you started. Airflow through the core is what actually changes your night.
Assuming gel infused foam sleeps cool
Gel infusion helps a little. It does not turn memory foam into a cooling mattress. I have had a lot of people come back frustrated because they bought a gel memory foam bed expecting the same result as a hybrid, and the marketing did not make the distinction clear.
Putting a plastic protector on a breathable mattress
This one quietly ruins good purchases. A cheap waterproof protector is basically a sheet of plastic across the top of the bed. Everything the manufacturer engineered for airflow stops at that layer. Get a breathable protector and it costs you almost nothing in cooling.
Ignoring how much you sink
Two mattresses with identical materials will sleep at different temperatures if one lets you sink four inches and the other two. The more of your body is surrounded by mattress, the less air reaches you. Firmness is a cooling variable and almost nobody thinks of it that way.
Testing cooling for thirty seconds
Surface materials feel cool to the touch immediately. That tells you nothing about hour four. When someone tells me they sleep hot, I ask them to lie down and stay there while we talk about something else for ten minutes. That is when you find out.

Why In-Store Testing Matters
Cooling is the hardest claim in this industry to evaluate from a product page, because every mattress sold advertises it. Terms like cooling gel, breathable, and temperature regulating are not standardized and mean very different things across brands.
What you can do is lie on two beds side by side for ten minutes each. Surface temperature at minute ten is a real signal, and it is not something you can get any other way.
Every Sit 'n Sleep store offers BedMATCH, a diagnostic fitting that takes about three minutes. You lie down on a calibrated bed while it takes more than one thousand measurements of your body, then narrows the floor to the comfort range that actually fits you. It is free and you do not need an appointment.
We have 37+ stores across Southern California, in Los Angeles, Orange County, the Inland Empire, and Ventura County. Find the store closest to you, and take your time. Every mattress is backed by our 120-night comfort trial.

Frequently Asked Questions
The best cooling mattress for hot sleepers is a hybrid with a pocketed coil support core, because air moves through the middle of the mattress in a way that no all foam bed can match. Latex hybrids sleep coolest of all, since latex does not hold heat and wool covers regulate temperature in both directions. If you want memory foam contouring, look for engineered cooling lines rather than standard foam with gel added.
Yes, but the effect depends entirely on construction rather than marketing language. A coil core that moves air makes a real and lasting difference across a full night. A phase change cover feels cool at first contact and the effect lessens as it saturates. Gel infused foam helps a little and does not turn memory foam into a cooling mattress.
Hybrid is better for hot sleepers in almost every case. Memory foam is dense and closed cell, so it holds body heat, and a solid foam core gives warm air nowhere to go. A hybrid puts comfort layers over an open coil structure that vents continuously. If you specifically want memory foam feel, engineered cooling lines close much of the gap.
Yes. The further you sink into a mattress, the more of your body is surrounded by material rather than exposed to moving air, so a softer bed of the same construction sleeps warmer than a firmer one. This matters for side sleepers who run hot, since side sleeping needs a softer surface. The usual answer is a hybrid with cooling treated comfort layers rather than choosing a firmness that does not fit your body.
For night sweats, moisture management matters as much as heat. Look for wool or Tencel in the cover rather than polyester, since those move moisture away from your skin instead of holding it, and pair that with a coil core for airflow. Also check your mattress protector, because many waterproof models block airflow entirely. Persistent night sweats can have causes unrelated to your mattress and are worth raising with your doctor.
Yes. An adjustable base lifts the mattress off a solid platform and lets air circulate underneath it, which a solid foundation or a platform bed with a flat deck does not allow. Elevating your head slightly also helps some people who overheat. Most hybrid and memory foam mattresses work on an adjustable base, though it is worth confirming compatibility.
