Best Cooling Mattresses
Most "cooling" mattresses are just marketing tricks. A tiny bit of gel foam won't stop night sweats. You need materials that pull heat away from your body.
At our showroom at 1441 Encinitas Blvd, we show you how the physics of sleep works. We tested hundreds of beds. These top picks are best for hot sleepers.
Technogel 3D Elite Hybrid
This bed uses a thick grid of medical-grade gel. It is not just a thin spray. The gel pulls heat away from your core. It was the coolest bed in our extended 60-minute cooling evaluation.
- Medical-Grade Gel: Moves heat away fast.
- 3D Conforming Grid: Relieves pressure.
- Zoned Coils: Allows deep airflow.
Helix Elite Series
This mattress is 16 inches tall. It uses a Cool Force Layer made of graphite ribbons. These ribbons soak up body heat before you feel it.
- Cool Force: Graphite ribbons absorb heat.
- GlacioTex Cover: Feels cold to the touch.
- Dual Micro-Coils: High internal airflow.
Yawnder Mattress
This is a great choice if you want natural materials. We used Tencel and Talalay Latex. Latex has open cells that breathe well to prevent heat buildup.
- Natural Talalay Latex: Breathes naturally.
- Tencel Cover: Wicks away moisture.
- Joma Wool: Controls temperature.
Cooling Tech Breakdown
San Diego Magazine named us Best Mattress Store in 2024, 2025 & 2026. We focus on what actually works. Real cooling needs airflow and heat conduction.
| Material | Cooling Mechanism | Best For |
|---|---|---|
| Medical-Grade Gel (Technogel) | Pulls heat deep away from the body. | People who get very hot at night. |
| Graphite Infusion (Helix) | Moves heat through the foam layers. | People who want a soft, plush feel. |
| Talalay Latex (Yawnder) | Open holes let air flow through. | Natural shoppers who want a bouncy bed. |
Why Most "Cooling" Mattresses Fail
Many brands just add a little gel to thick foam. This only stays cool for 15 minutes. Once the foam gets warm, it traps heat like a blanket. You need materials like Technogel that physically move heat away.
Don't Ruin It With Your Sheets
Do not use cheap polyester sheets on a cooling bed. Polyester is like plastic and traps heat. Use Cotton, Tencel, or Bamboo sheets instead. These fabrics let the mattress breathe.
Frequently Asked Questions About Best Cooling Mattresses – Real Tech for Hot Sleepers
Who are cooling mattresses best for?
Cooling mattresses are best for hot sleepers, people who live in warm climates like San Diego, and anyone who struggles with overheating during the night. These mattresses are engineered with specialized materials and technologies to dissipate heat and regulate body temperature for a more comfortable sleep.
Is a cooling mattress worth it for someone who sweats at night?
Yes, a cooling mattress can be greatly beneficial for someone who sweats at night by actively regulating temperature and wicking away moisture. Our hands-on testing at Yawnder shows that these mattresses significantly reduce night sweats, improving sleep quality. You can even try them out at our Encinitas showroom.
How do cooling mattresses compare to regular memory foam mattresses?
Cooling mattresses differ from regular memory foam by incorporating advanced heat-dissipating technologies, while traditional memory foam can often trap heat. These technologies include gel infusions, open-cell designs, phase-change materials, and breathable covers, all designed to prevent the mattress from retaining body heat. This makes them a superior choice for hot sleepers.
What are the downsides of cooling mattresses?
While highly effective, some cooling mattresses can be more expensive than traditional mattresses due to their advanced technology and specialized materials. However, their benefits in terms of sleep quality and comfort for hot sleepers often outweigh the initial cost. Customers can explore various options at Yawnder to find a mattress within their budget.
Is a cooling mattress good for side sleepers?
Yes, a cooling mattress can be excellent for side sleepers, especially those who also tend to sleep hot. The cooling properties ensure a comfortable temperature, while their supportive designs often provide the necessary pressure relief for the shoulders and hips required by side sleepers. Many models we carry are suitable.
Where can I try a cooling mattress in person?
You can try a variety of cooling mattresses in person at the Yawnder showroom located in Encinitas, CA. Our sleep experts are available to guide you through the options and help you find the best cooling mattress for your specific needs.

How these beds performed in our cooling test
Highest Standardized 20-Minute Cooling Scores
The ten highest standardized 20-minute cooling scores in our database, one pick per brand, refreshed automatically from the same records that power every review. 142 mattresses: 51 with complete standardized records and 91 with partial standardized records. Partial means some standardized testing categories are available. Missing values are shown as —.
Cooling is one of our instrument-measured categories: we log surface temperature at the shoulder and hip zones in the Encinitas showroom and score the result on a 10-point scale. Standardized score: a 20-minute loaded-contact test; extended cooling evaluation: an optional 60-minute run. We publish the category score for every mattress; the timed temperature traces themselves are not stored as per-model figures in our database, so the table shows scores, not degree readings.

Every bed above is one we have slept on and measured on the floor of our Encinitas showroom. Alongside the standardized 20-minute cooling score we run an extended 60-minute evaluation: a tester lies on the bed in the same room conditions, we log surface temperature at the shoulder and hip, and we watch what happens after the tester gets up.
The Technogel 3D Elite Hybrid was the only bed in this group whose surface temperature never trended upward after the 30-minute mark, and it returned to room temperature within about two minutes of the tester getting up. That is the difference between conducting heat away and simply delaying heat buildup, and it is why it stays our top pick for chronic hot sleepers.
Also on the floor: Black Diamond Snowbird Hybrid
Black Diamond builds the Snowbird the old way — a tall pocketed coil unit, natural fiber quilting, and very little polyfoam between you and the springs. The heat management comes from the sheer volume of open air inside the mattress plus quilting fibers that move moisture instead of holding it. It is the pick for someone who runs hot but wants a plush, hotel-luxury surface rather than a modern gel one. It starts at $2,299 (queen) and the related Lux Quilted Hybrid starts at $2,399 on sale.
Watch out for: plush tops always sleep a little warmer than firm ones. If you are an extreme hot sleeper, size up in firmness rather than down.
Surface cool vs. structural cool
This is the single most useful distinction when you are shopping for a cooling mattress or a mattress for hot sleepers, and almost no brand explains it.
Surface cooling comes from phase-change fabrics and specialty cooling covers. It feels noticeably cool — sometimes cold — the moment you lie down, which genuinely helps you fall asleep faster. But it works by absorbing heat, and once the fabric saturates, the sensation fades. It cannot prevent heat buildup across six to eight hours on its own.
Structural cooling is breathability from the inside out. A coil layer creates a large pocket of air that lets body heat dissipate all night. It does not feel cold to the touch, but it keeps heat from getting trapped around you. The best cooling mattresses combine both: a cool surface for sleep onset and a breathable core for the rest of the night.
What actually makes a mattress hot or cool
Coil systems: the gold standard for airflow
At the heart of any genuinely cool mattress is empty space. A steel coil support core creates a large internal chamber for air to circulate, and every time you move, that system works like a bellows — pushing warm air out and drawing cooler air in. A coil-based bed is structurally cooler than a solid block of foam, full stop. Coil-on-coil builds (smaller contouring coils over larger support coils) maximise both airflow and support; pocketed coils cut motion transfer while still leaving channels for heat to escape.
Latex: the coolest comfort layer
If you want the contouring of foam without the heat, natural latex is the answer. Its open-cell structure is inherently breathable, so heat and moisture wick away instead of pooling. Talalay latex in particular has a more consistent, airier cell structure, which makes it one of the most breathable comfort materials available.
Memory foam: the main offender, with caveats
Traditional memory foam is a closed-cell material that softens in response to your body heat — and then holds that heat against your skin. Two technologies push back on this:
- Gel infusions act as a heat sink for an initial cool-to-the-touch feel, but once the gel saturates (typically inside the first hour) it stops absorbing and can start retaining heat.
- Phase-change materials absorb heat when you are warm and release it as you cool. More active than gel, but they work best paired with a breathable coil core.
Cover fabrics: the first impression
The cover is the first thing your skin touches. Organic cotton, Tencel and bamboo all breathe and wick well. Some brands weave in conductive yarns or add phase-change treatments — Helix’s GlacioTex is the best-known example — for a crisp coolness on contact. It is real, but it cannot rescue a mattress with a non-breathable core.
Cooling needs by sleeper type
- Side sleepers: you need pressure relief and breathability at once. A medium-firm hybrid usually wins — a thick enough latex or responsive-foam comfort layer to cushion the shoulder and hip, over a pocketed coil core so heat does not get trapped in those pressure zones.
- Back and stomach sleepers: a firmer hybrid or latex bed keeps you resting on the mattress rather than in it, which naturally improves air circulation while holding your spine in line.
- Couples: two bodies mean twice the heat. A king or split-king pocketed-coil hybrid spreads airflow across the whole surface so heat does not concentrate in the middle, and the individually wrapped coils keep one partner’s movement from waking the other.
Who should skip a cooling mattress
Cooling tech is worth paying for if you wake up sweaty regardless of season, you and your partner disagree about temperature, you live somewhere warm, or you dislike the sunk-in feel of memory foam anyway.
Skip it if you naturally sleep cold and pile on blankets, if you are on a tight budget (a simple firm innerspring is breathable and cheaper), or if the deep, enveloping memory-foam hug is the one thing you cannot give up — airflow-first builds always mute that feel.
On the fence? Try a latex or graphite cooling topper first, swap heavy polyester bedding for linen, Tencel or cotton percale, and consider whether a larger mattress would simply put more space between you and a partner who runs hot.
More cooling mattresses worth considering
Beyond the beds on our showroom floor, these are the models we point hot sleepers toward most often. Scores, firmness ratings and queen pricing come from Yawnder’s canonical mattress database and change as brands adjust pricing.
| Model | Cooling | Overall | Firmness | Queen |
|---|---|---|---|---|
| Helix Midnight Elite Coil-on-coil airflow, best all-round cooling hybrid | 9.6 | 9.6 | 5.5 / 10 | $3,499 |
| Black Diamond Lux Quilted Hybrid Natural fibre quilting over a tall coil unit | 9.8 | 9.7 | 5.5 / 10 | $2,999 |
| Brooklyn Bedding Aurora Luxe TitanCool phase-change surface; the most actively cold feel here | 9.2 | 8.5 | 6.0 / 10 | $1,874 |
| DreamCloud Premier Hybrid Best hybrid value; passive cooling, not cold to the touch | 9.2 | 8.6 | 6.5 / 10 | $1,599 |
| Technogel 3D Pro Hybrid Same conductive gel as our top pick, lower price | 9.2 | 8.5 | 6.5 / 10 | $3,499 |
| Nectar Premier Copper Best all-foam option; copper-infused cover and gel foam | 8.8 | 8.4 | 6.0 / 10 | $1,499 |
| Helix Midnight Luxe Zoned coils for side sleepers; add GlacioTex for the cool-touch cover | 8.5 | 8.4 | 6.0 / 10 | $1,999 |
| Bear Elite Hybrid Celliant cover and copper-infused foam, three firmness options | 7.3 | 7.9 | 6.5 / 10 | $1,899 |
| Saatva Classic Coil-on-coil innerspring: maximum structural airflow, no phase-change layer | — | 9.3 | 6.5 / 10 | $1,995 |
Saatva also sells the Rx, a specialty support model with a dual-coil core and organic cotton cover that breathes well and is aimed at back and joint discomfort. We have not scored it in our canonical database yet, so we are not going to publish numbers for it here.
Saatva Classic vs. Helix Midnight Luxe
These two are the most common cross-shop for hot sleepers, and they get cool in fundamentally different ways.
| Feature | Saatva Classic | Helix Midnight Luxe |
|---|---|---|
| Primary cooling method | Structural airflow | Surface cooling fabric |
| Construction | Coil-on-coil innerspring, Euro pillow top | Memory foam over pocketed coils |
| Feel | Responsive; you sleep on it. Three firmness levels. | Contouring without deep sink; single medium feel. |
| Yawnder score | 9.3 | 8.4 |
| Firmness | 6.5 / 10 | 6.0 / 10 |
| Queen price | $1,995 | $1,999 |
| Trial / warranty | 365 nights | 100 nights, 10 years |
Pick the Saatva if all-night temperature neutrality and a classic responsive feel matter most. Pick the Helix Luxe if you want that first cool-to-the-touch contact and a gentler foam cradle.
What a cooling mattress actually costs over time
Well-built cooling queens generally run $1,500 to $3,500. Spread a $2,000 mattress across a conservative eight-year life and it works out to about $250 a year, $21 a month, or roughly $0.69 a night. That is also money you stop spending elsewhere: no replacing $100 cooling toppers every couple of years, and often a slightly higher thermostat setting through the summer.
Delivery, sleep trial and warranty
- Delivery: most online brands ship free, compressed in a box. Premium brands including Saatva include white-glove delivery and setup, which matters with heavy coil builds. Yawnder’s own white-glove delivery is $200.
- Sleep trial: this is the policy that matters most for a hot sleeper. Fifteen minutes in a showroom cannot tell you how a bed handles you across a full night in August. Trials run from 100 nights to a full year — use them.
- Warranty: expect at least 10 years, covering defects like sagging beyond about an inch, faulty zippers and failed seams. Heat retention is not a warranty defect anywhere, which is exactly why the trial period is your real protection.
More cooling questions we get asked
Are gel memory foam mattresses actually cooler?
Only marginally. The gel acts as a heat sink and delays heat buildup, so the surface feels cool at first. Once it saturates it stops absorbing. A coil-based hybrid or innerspring is the more effective all-night solution.
Can a mattress topper make my bed cooler?
Yes, noticeably — natural latex, graphite or copper toppers all improve surface cooling. But it is a surface fix. It will not rescue a dense, heat-trapping foam core underneath.
Do firm mattresses sleep cooler than soft ones?
Generally yes. Soft beds let you sink into the comfort layers, which increases contact area and cuts airflow around your body. Firmer models keep you on top of the mattress, where air can move.
What is the absolute coolest type of mattress?
Structurally, a coil-on-coil innerspring — it has the most internal air volume of any design. Among comfort materials, natural latex is meaningfully cooler than any memory foam, gel-infused or not.
Besides the mattress, how else can I sleep cooler?
Breathable bedding in linen, Tencel or long-staple cotton, lightweight sleepwear, and a bedroom held between 60 and 67°F. A cooling pillow helps more than most people expect.

Night sweats vs. simply running warm
Running warm and having night sweats are different problems, and they call for different features. Running warm means you wake up uncomfortably hot. Night sweats are episodes where you wake up genuinely soaked — damp sheets, a change of pajamas. They are commonly associated with perimenopause and menopause, thyroid conditions, infections, some medications including SSRIs, and sleep apnea. A mattress is comfort equipment, not a medical device, and it cannot treat the underlying cause — if the episodes are new, frequent, or worsening, that is a conversation for a clinician. What the right surface can do is stop trapping the moisture against your skin.
For someone who runs warm, a cool-to-touch cover over a coil base usually solves it. For true night sweats, the priority shifts from surface temperature to moisture management: the bed needs to breathe so heat can escape, and wick so sweat is pulled off the skin instead of pooling.
What to look for if you sweat at night
- Wool or natural latex. Wool is one of the most moisture-wicking fibres available and shows up as a fire barrier or cover on natural-latex builds such as Saatva Zenhaven. Latex’s open-cell structure keeps air moving instead of holding it.
- Coil-on-coil hybrids with a breathable cover. Air moves through the bed rather than sitting next to you, which is why hybrids consistently outperform all-foam beds here.
- Phase-change or cool-to-touch covers. These help with the initial heat surge that often kicks off an episode, but they are a surface fix — pair them with a breathable core.
- A moisture-wicking protector. The cheapest meaningful upgrade for night sweats. A waterproof vinyl-backed protector will undo the airflow of any mattress underneath it; look for a breathable membrane instead.
- What to avoid: dense all-foam memory foam. It insulates, and it holds moisture against the body.
Split-firmness and dual-temperature setups are worth considering when only one partner sweats, so one side can be cooled without freezing the other.
