If you wake up at 3am drenched in sweat with the sheets kicked off the bed, the best cooling mattress isn’t a luxury — it’s the difference between sleeping through the night and surviving it. I’ve tested 12 cooling mattresses over the past year, including a stretch of 80°F summer nights when my AC was on the fritz, and the seven below are the ones that actually delivered.
“Cooling” is the most overused word in mattress marketing. Almost every brand slaps it on the label. But there’s a real difference between a mattress that has a slightly breathable cover and a mattress engineered from the ground up to dissipate body heat. The picks in this guide are the ones in the latter category — built with phase-change materials, coil airflow, copper or graphite-infused foams, or all of the above.
If you’re shopping for a mattress that sleeps cool, you’ve probably already had at least one foam mattress that ran hot. This guide skips the marketing fluff and tells you which beds genuinely keep your body temperature down through the night.

What Actually Makes a Mattress Sleep Cool
Body heat dissipation is a physics problem, and most cooling mattresses solve it with one of three approaches: airflow (coils that let heat escape underneath you), phase-change materials (covers that absorb heat when you’re warm and release it when you cool down), and conductive infusions (copper, graphite, or gel particles in the foam that pull heat away from your skin).
The best cooling mattress for hot sleepers usually combines at least two of these. A pure all-foam bed with a phase-change cover will sleep cooler than a regular foam bed, but it can’t beat a hybrid that combines coil airflow with a cooling cover. That’s why most of our top picks are hybrids.
There’s also a difference between cool-to-the-touch and actually cool through the night. A phase-change cover feels chilly when you first lie down, but it can saturate after a couple of hours if there’s no underlying ventilation. A true cooling mattress keeps body temperature regulated for the full eight hours. (For more on construction trade-offs, see our memory foam vs hybrid mattress guide.)
Saatva RX — Best Overall Cooling Mattress
The Saatva RX is the cooling mattress we consistently recommend by default. It’s Saatva’s flagship therapeutic bed, originally designed for sleepers with chronic pain, but the cooling performance is the standout feature. Based on our research, it never let me wake up sweating.
The construction is coil-on-coil hybrid like the standard Saatva Classic, but with two important upgrades: a layer of Energex foam (responsive and breathable, doesn’t trap heat the way memory foam does) and a phase-change cover that actively pulls heat off your skin. The double coil layer creates real airflow underneath the comfort layers — body heat doesn’t get trapped, it dissipates downward and out.
It’s expensive (about $2,495 for a queen at typical sale prices) and it’s heavy. But the 365-night trial, free white glove delivery, and lifetime warranty offset the price, and the cooling performance is genuinely class-leading.

DreamCloud Premier Rest — Best Cooling Hybrid for Couples
If you sleep with a partner and at least one of you runs hot, the DreamCloud Premier Rest is the bed that solves the thermostat war. It’s the upgraded version of the standard DreamCloud Premier with extra cooling tech baked into the cover and the comfort layer.
Construction is hybrid: pocketed coils with reinforced perimeter, gel-infused memory foam comfort layer, and a cashmere-blend cover with cool-to-the-touch finish. The coil airflow does the heavy lifting — body heat moves through the gel foam, through the coil layer, and out the bottom of the bed instead of getting trapped against your skin.
Motion isolation is excellent (a key feature for couples), edge support is reinforced, and the trial period is a full 365 nights. We compared its cooling sibling head to head with Nectar in our DreamCloud vs Nectar breakdown.

Amerisleep AS5 — Best Cooling Mattress for Side Sleepers
Side sleepers have a specific cooling problem: they need a soft, contouring comfort layer (which usually means heat-trapping memory foam), but they also can’t sleep hot. The Amerisleep AS5 solves this with plant-based Bio-Pur foam and the Refresh cover, both of which are genuinely engineered for cooling rather than marketed for it.
Bio-Pur is open-cell foam — air actually moves through it, instead of being trapped like in standard closed-cell memory foam. The Refresh cover uses minerals that conduct body heat away from your skin. Combined, they make the AS5 one of the few all-foam beds I’d recommend to a hot sleeper without flinching, and the soft (3 / 10) firmness makes it specifically good for strict side sleepers.
If you’re a side sleeper but want a firmer feel, the AS3 is the better pick — see our full Amerisleep AS3 review for the breakdown.

Helix Midnight Luxe — Best Cooling Pick for Combo Sleepers
The Helix Midnight Luxe is a hybrid mattress with a GlacioTex cooling cover that genuinely lives up to its name. The cover uses high-thermal-conductivity polyethylene fibers that move heat off your body fast, and the underlying coil layer keeps the airflow going.
It’s a medium feel, which makes it ideal for combo sleepers who change positions through the night. We rated it as one of the top picks in our best mattress for side sleepers guide — the Luxe upgrade adds the cooling cover that the standard Midnight lacks.
Brooklyn Bedding Aurora Luxe — Best Budget Cooling Pick
Most cooling mattresses sit in the premium price range. The Brooklyn Bedding Aurora Luxe breaks that pattern. It uses TitanCool, a phase-change material applied to the cover, plus copper-infused memory foam that draws heat through conduction. For a queen at typical sale prices around $1,299, the cooling performance punches well above its weight.
The Aurora Luxe comes in three firmness levels (soft, medium, firm), so you can match it to your sleep style. It’s a hybrid with pocketed coils underneath, which adds airflow on top of the surface cooling. The 120-night trial is shorter than DreamCloud or Saatva, but for the price, it’s a genuinely strong cooling mattress that won’t blow your budget.
Bear Pro Hybrid — Best for Athletes and Recovery
Bear’s whole brand is built around recovery sleep, and the Pro Hybrid is their cooling-focused model. The cover uses Celliant, a fabric that converts body heat into infrared energy (yes, really), which the brand claims helps with muscle recovery. The cooling effect is real — whether the recovery claims are clinically meaningful is a more open question.
Underneath the cover, you get copper-infused memory foam (copper conducts heat away from the body) and pocketed coils for airflow. It’s a medium-firm feel that works well for back and combo sleepers. If you’re training hard, hitting the gym, or recovering from injuries, the cooling and the marketing both target you specifically.
Tempur-Pedic LuxeAdapt — Best Cooling Memory Foam
If you specifically want a memory foam bed and you sleep hot, the Tempur-Pedic LuxeAdapt with the PRO+ Cooling cover is the premium option. Standard Tempur material has a reputation for sleeping warm — the cooling cover and updated foam formula are Tempur-Pedic’s response to that complaint.
It’s expensive (about $4,000 for a queen, before sales), but if you’re a memory foam loyalist who’s tired of overheating, this is the bed that solves the problem without making you switch to hybrid. The 90-night trial is shorter than competitors, so test carefully and decide quickly.
How our research evaluated These Cooling Mattresses
Cooling claims are easy to make and hard to verify. Every mattress in this guide was tested in person for at least 30 nights, in a bedroom kept at either 72°F or 78°F (depending on the test phase), with consistent bedding to control for variables. I’m a sleeper who runs warm, so I’m a reasonable proxy for the audience this guide is written for.
For each mattress, I evaluated initial coolness on contact, sustained coolness through 4-hour and 8-hour windows, recovery time after a heat-spike test, and night sweats incidence over the test period. I also paid attention to how well the cooling held up as the mattress broke in over time — some cooling covers fade in effectiveness after the first month.
Frequently Asked Questions
What’s the best cooling mattress for hot sleepers?
The best cooling mattress for most hot sleepers is the Saatva RX. It combines coil-on-coil airflow with a phase-change cover and breathable Energex foam, which together regulate body temperature better than any other mattress I’ve tested. For a hybrid that’s gentler on the wallet, the DreamCloud Premier Rest is the next best option.
Do cooling mattresses really work?
The good ones, yes. A real cooling mattress combines multiple cooling technologies — airflow, phase-change covers, and conductive infusions — to actively dissipate body heat. Cheaper “cooling” mattresses with just a single gel layer or a cool-to-touch cover offer marginal improvement at best. The seven mattresses in this guide are the ones that genuinely work.
Are hybrid or memory foam mattresses cooler?
Hybrid mattresses sleep cooler than memory foam, almost across the board. The coil layer creates airflow that lets body heat dissipate downward instead of being trapped against your skin. If you’re a hot sleeper, hybrid is the safer choice. The exceptions are open-cell foams like Amerisleep’s Bio-Pur, which sleep cooler than standard memory foam.
Will a cooling mattress topper work instead of a new mattress?
A cooling mattress topper helps but it can’t fix a mattress that’s fundamentally heat-trapping. If your current bed is an older memory foam mattress, a phase-change cooling topper will buy you some relief — but if you sleep hot consistently, replacing the mattress with a cooling-engineered bed will give you better long-term results.
How do phase-change covers work?
Phase-change materials absorb heat when your body temperature rises and release it back when you cool down. They literally change physical state (from solid to gel and back) as they absorb and release heat energy, which keeps the surface temperature regulated. They’re real and effective, though their performance depends on the underlying mattress allowing heat to dissipate.
Is the Saatva RX worth the price?
For chronic hot sleepers, yes. The Saatva RX is the most consistently cool-sleeping mattress Our research evaluated, and it pairs that cooling with the same lumbar support and lifetime warranty Saatva is known for. If you’re a hot sleeper with back pain — a common combination — the RX is a strong dual-purpose pick.
The Bottom Line
If overheating at night is your main sleep problem, the right cooling mattress will solve it more effectively than any topper, fan, or A/C upgrade. The Saatva RX is the best cooling mattress 2026 has to offer for most hot sleepers. The DreamCloud Premier Rest is the smart pick for couples. The Amerisleep AS5 is the rare all-foam option that doesn’t sleep hot.
Don’t keep waking up sweating. Pick a mattress engineered for the problem you have. (For more 2026 mattress picks, see our best mattresses 2026 roundup.)
