If you tend to sleep hot or get night sweats, the right cooling mattress can make a world of difference in keeping you comfortable while you doze. "The best cooling mattresses are usually made out of gel or latex and feature a cotton or bamboo cover," says Logan Foley, a Certified Science Sleep Coach and Managing Editor at SleepFoundation.org.

Using expert insights into temperature-regulating materials, research, and testing, we judged standout options for every sleep style and budget. Based on our findings, our number one pick is the Cocoon by Sealy Chill Hybrid Mattress, a foam-coil hybrid with temperature-regulating technology and a cool-to-the-touch cover.

Here are the best cooling mattresses on the market.

What We Like
  • Excellent breathability

  • Phase-change material

  • Edge support

  • CertiPUR-US certified

What We Don't Like
  • Slight odor out of the box

  • No handles on the cover

  • Heavy

The best cooling mattress option overall is undoubtedly the Cocoon Chill. It earned a 4.5 out of 5 overall score from our home tester, who liked its exceptionally breathable and cool-to-the-touch cover. She also said it offers excellent support while contouring to the shape of your body.

This 12-inch-thick hybrid mattress combines CertiPUR-US certified memory foam with fabric-encased coils to minimize motion transfer and support spinal alignment in any sleeping position. Not only that, but reinforced edge support around the perimeter prevents you from sinking down when sitting on the mattress or climbing in and out of bed.

Infused with a science-backed phase-change material (PCM), the cover actively draws warmth away from your body to keep you comfy throughout the night, while the Bolsa coils promise to dissipate heat. There's also an Extra-Chill version of the mattress with PCM-infused memory foam. Although it's pretty heavy, our tester said the bed-in-a-box format makes it super easy to set up. There's also a slight odor upon opening the box, but it dissipates quickly.

Best Budget: Classic Brands Cool Gel Ventilated Memory Foam Mattress

Cool Gel 12" Medium Gel Memory Foam Mattress

Wayfair

What We Like
  • Ventilated foam

  • Medium firmness

  • CertiPUR-US certified

What We Don't Like
  • Cover isn't machine-washable

  • Might require up to 72 to fully expand

We highly recommend the Cool Gel Mattress from Classic Brands for folks on a budget. It's made of gel-infused ventilated memory foam to encourage airflow. According to Sleepfoundation.org sleep expert Logan Foley, the gel component can help draw warmth away from your body and prevent the foam from trapping heat.

The medium firmness offers the perfect amount of support while resisting motion transfer. We appreciate that the memory foam is CertiPUR-US certified, ensuring it meets strict performance, durability, and emissions standards. Though the cover isn't machine-washable, it's soft, stretchy, and breathable. For best results, you might want to wait the entire 72 hours recommended by the manufacturer to ensure the mattress fully expands.

  • CertiPUR-US certified

What We Don't Like
  • Cover isn't machine-washable

  • Might not be as supportive for some

Open to spending a bit more to achieve your best night's sleep? You may want to consider the Serta Arctic. This splurge-worthy mattress calls on a phase-change material to absorb heat and provide all-night temperature regulation.

It's made up of four layers, starting with a supportive foam encasement with individually wrapped micro-coils, followed by gel-infused memory foam, then high-density conforming foam, and PCM on top. While the Arctic doesn't have a washable cover or provide quite the firmness some sleepers need, we like that the memory foam is CertiPUR-US certified.

Amazon

What We Like
  • Reasonably priced

  • Multi-layer design

  • CertiPUR-US certified

What We Don't Like
  • Takes a few days to expand

  • Heavy

If you're partial to memory foam, consider the Zinus Cooling Mattress. Our home tester gave it a 4.5 out of 5 overall score, noting how the multi-layer design conforms to your body while an infusion of green tea extract keeps odor-causing bacteria at bay. The upper layer is infused with gel to provide a continuous cooling effect.

We appreciate that the memory foam is CertiPUR-US certified, ensuring not only quality but also that it won't emit potentially harmful substances. Our tester said this mattress takes a few days to expand and is a bit cumbersome to move around (the queen-size option weighs over 60 pounds). But considering the agreeable price point, it's a solid choice.

4.8
Boll & Branch

Boll & Branch

What We Like
  • Multi-layer design

  • Thermal-regulating

  • Organic cotton cover

What We Don't Like
  • Expensive

  • Slightly squeaky coils

Not a fan of foam? Go with Boll & Branch. This mattress clocked an impressive 4.8 out of 5 overall score from our home tester, who said it offers luxurious comfort and gentle support while isolating movement. Though the springs are slightly squeaky, she also liked the cooling properties, noting that it's ideal for hot sleepers. 

The four-layer design starts with foundational springs on the bottom, followed by individually wrapped micro-coils, graphite-infused latex, and a wool-poly blend on top. Wool is a naturally breathable and thermal-regulating material. And according to the maker, the graphite helps draw heat away from your body, while the coils encourage airflow. This mattress earns extra points for the organic cotton cover.

What We Like
  • Excellent breathability

  • Edge support

  • CertiPUR-US certified

What We Don't Like
  • Slight odor out of the box

  • Cumbersome to move

Tuft & Needle's Mint Mattress clocked a 4.8 out of 5 overall score from our home tester. She appreciated how cool it sleeps for a foam model and loved the soft, breathable cover. What's more, she said the adaptive foam's medium firmness offers a perfect balance of support and cushioning for different sleep styles.

Graphite and cooling gel promise to draw heat away from your body while edge support ensures you don't get swallowed by the mattress. Though our tester noted a temporary odor out of the box, it's CertiPUR-US certified to ensure it doesn't emit harmful chemicals. It's also somewhat hard to move around (the queen-size mattress weighs 80 pounds), but the Mint was an all-around hit in the end.

Best Copper-Infused: Layla Copper-Infused Memory Foam Mattress

Layla Memory Foam Mattress

Layla

What We Like
  • Excellent breathability

  • Reversible

  • Lifetime warranty

What We Don't Like
  • Heavy

  • Flipping requires second pair of hands

Foley says hot sleepers should look for copper-infused models, like this thoughtfully designed option from Layla. Copper is a naturally conductive material, which helps the memory foam surface carry heat away from your body to keep you cool while you sleep. Additionally, the ventilated foam layer underneath encourages circulation to enhance breathability and prevent overheating.

What really stands out about this mattress is its reversible design. It's soft on one side for those who prefer a plusher feel and firm on the other to support back and stomach sleepers. Just bear in mind flipping it isn't the easiest, as the queen size weighs nearly 70 pounds.

Material: Copper-infused memory foam, ventilated foam | Sizes: Twin, twin XL, full, queen, king, Cal. king | Thickness: 10.5 inches | Firmness: Medium | Warranty: Lifetime

Best Hybrid: Bear Luxury Hybrid Mattress

Luxury Hybrid Mattress

Bear

What We Like
  • Moisture-wicking cover

  • Edge support

  • CertiPUR-US certified

  • Lifetime warranty

What We Don't Like
  • Pricey

  • Heavy

  • Could feel too rigid for some

The Bear Hybrid has a foundation of fabric-encased innerspring coils, followed by a thick layer of copper-infused, CertiPUR-US certified memory foam to provide ample support and pressure relief while drawing heat away from your skin. Copper is also naturally antimicrobial, so it won't harbor odor-causing bacteria.

On top, you've got hand-quilted plushness and Feran Ice fabric, a patented sweat-wicking material that's cool to the touch. In addition to offering the best of all worlds with its multi-layer design, edge support prevents you from sinking in when you sit down. Though this mattress is cumbersome (the queen-size option weighs over 100 pounds) and on the pricier side, we appreciate the lifetime warranty.

Material: Copper-infused memory foam, fabric-encased coils | Sizes: Twin, twin XL, full, queen, king, Cal king, split king | Thickness: 13 inches | Firmness: Medium-firm | Warranty: Lifetime

Best Firm: Beautyrest Carbon Series Harmony Lux Mattress

Carbon Series Harmony Lux Mattress

Pottery Barn

What We Like
  • Excellent breathability

  • Edge support

  • CertiPUR-US certified

What We Don't Like
  • Pricey

  • Heavy and cumbersome to move

If you're a back sleeper or prefer a firmer mattress, the Beautyrest Harmony Lux is your best bet. This hybrid model features pocketed coil springs on the bottom to provide ample support, followed by high-density carbon-infused foam, which, according to the maker, offers a consistent cooling effect.

On top, there's a thinner gel-infused layer with the brand's signature InfiniCool surface that promises to keep odor-causing bacteria at bay while offering a cool-to-the-touch sensation. Not only that, but edge support around the perimeter provides enhanced sturdiness. The Harmony Lux is a little pricey, but it's among the best in terms of firmness. If you want something softer, two other firmness levels are available, as is the option to add a pillow-top layer.

Material: Gel, carbon-infused memory foam, fabric-encased coils | Sizes: Twin, twin XL, full, queen, king, Cal. king | Thickness: 13.5 inches | Firmness: Extra-firm | Warranty: 10 years

Final Verdict

Our top choice is the Cocoon Chill Hybrid Mattress. It earned a 4.5 out of 5 overall score from our home tester, thanks to its excellent breathability, temperature-regulating technology, and edge support. If you're looking for something a bit more affordable, we recommend the Classic Brands Cool Gel Mattress, which encourages airflow and provides a heat-dissipating effect.

What to Look For in a Cooling Mattress

Material

When shopping for a cooling mattress, Foley recommends steering clear of one material. "Memory foam tends to hold heat, so I would stay away from it altogether if you're an especially hot sleeper," says Foley.

That said, some memory foam mattresses include ventilation to encourage airflow and breathability. Foley recommends options infused with cooling gel beads or copper, which can help dissipate heat. Some models also feature phase-change materials (PCM) on the surface, cover, or coil casings, which has a similar effect of actively drawing warmth away from your body.

Firmness

Firmer mattresses tend to be best for back sleepers, as they offer support while promoting spinal alignment. Medium and medium-firm models work well for side sleepers because they help prevent the hips and shoulders from sinking and keep lower back pain at bay. Of course, some people sleep best on softer surfaces. If that's your preference, look for a plush or pillow-top mattress.

Thickness

Mattresses also come in varying thicknesses. On the lower end, you're looking at about 6 inches; on the higher end, it's closer to 14 inches. Thicker models typically cost a bit more but tend to provide more support and last longer, as they're less prone to sagging. The best options are at least ten inches thick, though 12 or more inches is ideal for most people.

FAQ
  • What is a cooling mattress?

    A cooling mattress keeps you at a comfortable temperature while you sleep by drawing heat away from the body. This type of mattress is ideal for those who sleep hot or are prone to night sweats.

    "When we're talking about cooling mattresses, the marketing can be slightly misleading," says Foley, explaining that they don't actively 'cool' you. "Instead, think of them as 'temperature-regulating.'"

  • How do cooling mattresses work?

    Cooling mattresses call on temperature-regulating materials to draw heat away from your body, enhance breathability, and wick away moisture. These fabrics include natural textiles like wool and cotton and conductive substances like carbon and copper.

    Brands also often use ventilated foam, gel-infused memory foam, and phase-change material in their cooling technology. "While they won't cool you with cold water like in some high-tech mattress pads, they won't absorb heat like others on the market," notes Foley.

  • What can I do if my bed is too hot?

    Aside from a temperature-regulating mattress, one of the best things you can do to prevent overheating at night is upgrade to cooling bedding. While microfiber is often touted as a cooling fabric, natural textiles like cotton, linen, and bamboo are ideal, as they're inherently breathable with moisture-wicking properties. A ceiling fan can make a big difference too.
