The best cooling mattress pulls heat away from your body and lets air move through the bed, so you are not flipping your pillow at 3 a.m. Hot sleepers still run warm in winter under heavy duvets and with the heat on, which makes this a year-round buy. We compared specs, expert testing and owner reviews to pick ten beds that stay comfortable for warm sleepers, from under-$400 foam to premium latex hybrids.

1. Bear Elite Hybrid: Best Cooling Mattress Overall
Bear’s Elite Hybrid earned a perfect temperature-regulation score in Tom’s Guide testing. It combines copper-infused foams that draw heat away from the surface with an optional Celliant-infused cover, over a layer of individually wrapped coils that keeps air moving.

2. Brooklyn Bedding CopperFlex Pro Hybrid: Best Mid-Range Cooling Mattress
The CopperFlex Pro gives you premium cooling materials without a premium price. Copper-infused foams and a GlacioTex cover feel cool to the touch, and about 760 wrapped coils add bounce and airflow. Tom’s Guide’s tester slept well on it during a heatwave in an attic bedroom.
It feels plusher than most medium-firm hybrids, which suits side and combination sleepers who like some cushion.

3. Helix Midnight Luxe: Best Cooling Mattress for Side Sleepers
Helix’s Midnight Luxe is a medium-firm hybrid tuned for side sleepers, with pressure-relieving foams at the shoulders and hips and good lumbar support. Testers found it shed heat quickly and stayed temperature neutral during a hot Arizona September, and Fortune named it its top cooling pick.
Helix sells an upgraded GlacioTex cooling cover as an add-on if you want an extra-cool surface.

4. Brooklyn Bedding Thermobalance LX Elite: Best Luxury Cooling Mattress
This tall latex hybrid pairs Talalay latex, which is naturally springy and breathable, with dedicated cooling layers. In a Tom’s Guide test meant to mimic a hot flash with an elevated body temperature, the tester felt no heat buildup or hot spots.
It comes in three firmness levels and is backed by a 120-night trial and lifetime warranty.
Key specs
- Type: latex hybrid, 14 inches tall
- Firmness: three levels
- Cooling: Talalay latex plus cooling layers

6. Nectar Classic Memory Foam Mattress: Best Cooling Memory Foam
Memory foam has a reputation for sleeping hot, but Nectar’s Classic uses a cooling cover with cooling fibers and returns to a neutral temperature quickly, according to Fortune. Its foams are CertiPUR-US certified and it carries a 365-night trial, one of the longest in the business.
It feels firmer than many memory foam beds, which back and combination sleepers often prefer.

- Firmness: medium-firm
- Cooling: cooling-fiber cover
- Trial: 365 nights
- CertiPUR-US certified foams
👍 Pros
|

7. DreamCloud Classic Hybrid: Best Value Firm Hybrid
DreamCloud’s Classic Hybrid includes a CloudQuilt cooling cover with cooling fibers at no extra charge, plus a 365-night trial and lifetime warranty. Its coil base keeps air circulating better than solid foam.
It runs firm, so it is better for back sleepers and heavier side sleepers than for petite sleepers.

9. SweetNight CoolNest Memory Foam Mattress: Best Cheap Cooling Mattress for Side Sleepers
SweetNight’s CoolNest uses phase change material that absorbs heat as it warms, and it scored well for heat dissipation in Tom’s Guide testing even though thermal imaging showed some trapped warmth. It is a medium-firm foam bed that works for side and back sleepers at a very low price.
Edge support was a surprise strength for a budget all-foam mattress.
Key specs

The Siena is about as inexpensive as a well-reviewed mattress gets. It is very firm, and while lab tests found it holds some heat, Tom’s Guide’s tester still slept comfortably and found it cool for an all-foam bed.
Its firmness and solid edges make it a good guest-room or kids’ bed for back and stomach sleepers.

How to choose the best cooling mattress
Construction
Hybrids and latex beds sleep coolest because coils and latex let air move. All-foam beds can still work if they use gel, graphite, copper or phase change materials.
Cooling materials
Copper and graphite pull heat away, phase change material absorbs it, and cooling-fiber covers feel cold to the touch. Check whether the cooling cover is included or an upcharge.
Firmness and sleep position
Side sleepers usually want soft to medium, back sleepers medium to medium-firm, and stomach sleepers firm. Softer beds let you sink in, which can trap more heat.
Body weight
Heavier sleepers sink deeper and may run warmer, so a supportive hybrid or latex bed is often a better choice than plush foam.
Trial and warranty
Look for at least a 100-night trial, and check return fees. Some brands, like Nectar and DreamCloud, offer 365 nights.
Bedding matters
Breathable sheets, a cooling pillow and a lighter duvet help any mattress sleep cooler. Active systems like water- or air-based bed coolers go further for very hot sleepers.
FAQ
What type of mattress sleeps the coolest?
Hybrids and latex mattresses generally sleep coolest because their coils and open-cell latex let air circulate. Memory foam can sleep warmer unless it has cooling infusions or a cooling cover.
Do cooling mattresses really work?
They help, but they do not work like an air conditioner. Most reduce heat buildup and feel cooler to the touch. If you sleep extremely hot, pair one with breathable bedding or an active bed cooling system.
Is a cooling mattress worth it in winter?
Yes, if you run warm. Heavy blankets and a heated room trap body heat in winter too, and a breathable bed keeps you from waking up sweaty.
How long does a cooling mattress last?
Most quality hybrids and latex beds last about 7 to 10 years, while budget foam may wear sooner. Rotate it as the manufacturer recommends and use a breathable protector.
