Cooling Mattress

There’s nothing worse than being uncomfortable at night and not being able to get enough sleep. For those who tend to run hot while sleeping, looking into a cooling mattress might be an effective solution. 

Cooling mattresses make it easier for the transfer of heat because of their built-in ventilation systems, which help prevent the body from overheating and create a more comfortable environment. Brandon Peters, M.D., who is board-certified in both neurology and sleep medicine, explains that there is “evidence that a cooler sleep environment helps to promote deep sleep. This is important for the repair of the body's tissues, and may help with growth.”

Although a cooling mattress can’t fix all your problems, it can certainly cut down on the night sweats and help you achieve a better night’s sleep. Getting inadequate hours of rest or sleep of poor quality can cause effects of sleep deprivation. “This may affect mood, attention, and memory. It may increase pain. It may also lead to long-term problems, including weight gain, cardiovascular disease, cancer risk, and overall increased mortality,” adds Dr. Peters.

Here are the best cooling mattresses on the market today.

Best Overall: Saatva Classic Mattress

Saatva Classic in Luxury Firm
Pros
  • 180 night home trial

  • Free delivery, setup, and old mattress removal

  • Good customer service

Cons
  • Mattress can sag

  • It can transfer movement if the bed is shared

This is Saatva’s most popular mattress for a reason: It combines the strength and resilient feel of an innerspring with the softness of eco-friendly memory foam. Together, these features focus on back and joint pain, as well as spinal support. What really promotes its cooling nature is the mattress’ individual comfort coils that respond and contour to the movements of your body in order to decrease motion transfer, while also increasing airflow for better breathability. 

Saatva provides three different types of firmness, including plush soft, luxury firm, and firm to match customer’s specific sleep needs. According to the website, most customers go with the luxury firm because it fits most sleep styles—and it doesn’t hurt that the quality or cost does not change based on chosen firmness.

What the Experts Say

Dr. Peters says that the benefits of a cooling mattress “may be evident fairly quickly. One night of recovery sleep may ease the effects of sleep deprivation. As we are conditioned to our environment, this may take more time. It might be expected that most people would adjust within weeks to a few months.”

Best Budget: Sealy Cocoon Chill by Sealy

Cocoon chill by Sealy
Pros
  • 10-year warranty

  • Excellent value

Cons
  • Trial period is only 10 days

Sealy’s Cocoon Chill provides a quality cooling mattress on a budget. The mattress has four layers: the essential support layer is a highly robust foam that focuses on resiliency; the responsive comfort foam reduces motion transfer, thereby preventing sinking; the perfect fit memory foam adapts and supports your body size, shape, and sleep position; and the cooling cover works to absorb and dissipate heat. All these layers help to create a breathable, soft mattress that takes away the heat and sweat of a bad night’s sleep. Since the Cocoon Chill is a firmer mattress, available in medium-soft and extra firm, it’s the most ideal for back and stomach sleepers.

The Brooklyn Aurora mattress from Brooklyn Bedding utilizes TitanCool to deliver cooling relief and provide a more comfortable sleeping environment.

By regulating the body’s temperature and using copper gel-infused foam to target pressure points and contour to your body upon shifting, this mattress can help you remain at ease throughout the night. When it comes to your Brooklyn Aurora, you can choose from three different firmness levels—plush, medium, and firm—to make sure the feel and level of support are right for you.

Lucid 3-Inch Memory Foam Mattress Topper
Pros
  • Three-year warranty

  • Good value

Cons
  • Off-gassing smell typically lasts for 48 hours when the mattress is opened

While buying a new mattress that better suits your sleeping needs is an option, so is buying a mattress topper to add to your existing mattress. Not only does it bring you comfort, but it can save you money. The ventilated gel memory foam mattress topper from Lucid is a great addition to any bed; its gel-infused foam helps to capture and distribute heat to create a more comfortable sleep experience. The three-inch topper is ventilated to improve airflow and regulate temperature, while the foam itself contours to the body to better align the spine and relieve pressure points around the shoulders, hips, and knees. 

Don’t be alarmed when you first open the topper to remove it from the casing and smell a particular foam scent. That's normal and it will disappear after 48 hours. While that scent doesn’t last long, luckily, the warranty does, for three years.

Final Verdict

If you don’t want to spend the extra money to buy a whole new mattress for the main purpose of helping you cool down at night, the LUCID 3-inch Ventilated Gel Memory Foam Mattress Topper (view at Amazon) is the way to go. It provides all the comfort and airflow without the hefty price tag. However, if you’re ready to change your mattress, give the Saatva Classic Mattress (view at Saatva) a try. It’s on the more expensive side, but the eco-friendly, breathable mattress is worth the extra spend.

What to Look for in a Cooling Mattress

Ventilation

When you have a well-ventilated mattress, it makes for better airflow, resulting in a more breathable mattress. This helps to take away heat and sweat during sleep. A perforated mattress topper for ventilation may help further cool you while you sleep, and is a great option for anyone on a budget.

Comfort

Making the switch to a cooling mattress can’t just be about the cooling effect. You have to make sure that other factors, such as firmness, springs, and foam are comfortable for you. Fortunately, many online retailers offer a trial period and warranty, so you can feel good knowing you're getting the best option for you.

Maintenance

Mattress toppers and mattress protectors can help extend the life of your mattress. Plus, they make cleaning easy, so any mattress mishaps won't mean throwing the whole product away. If you're looking to make a big investment in a cooling mattress, think about purchasing a protector or topper to help keep your mattress safe.

Frequently Asked Questions

  • How do cooling mattresses work?

    Even though there are plenty of cooling mattress options on the market right now, they tend to follow the same basic principles, according to Gregory Funk, D.C., a chiropractor and owner of Ideal Health Chiropractic in Denver, Colorado. “Essentially, cooling mattresses use various types of materials like gel-infused memory foam or cool-to-the-touch materials to draw hot air away from the body and absorb it,” he tells Verywell Health. “These materials should help your body stay cool throughout the night.”

    According to RJ Burr, D.C., a chiropractor with Start Sleeping and founder of REACH Rehab + Chiropractic Performance Center in Plymouth, Michigan, additional technologies used in cooling mattresses include “multiple layers of foam to help promote air circulation” and “variations on foam that allow for heat to disperse.” Similarly, as Jason Loth, D.C., a chiropractor and sleep expert at Nevy Health in Mesa, Arizona points out, some cooling mattresses have a top layer made with copper-infused foam. “The copper's conductivity assists in the transfer of heat, to help you sleep cooler and better,” he says. 

    So how is that different from regular/non-cooling mattresses? “Material in some mattresses can act as an insulator, keeping the heat and humidity from escaping much like a winter jacket,” says Kevin Lees, D.C., a chiropractor and the manager of auditing and quality of The Joint Chiropractic. “Cooling mattresses can help body heat escape and can be breathable.”

  • Can a cooling mattress help you sleep better?

    Cooling mattresses can help people whose sleep is consistently disrupted by night sweats or simply feeling too hot to sleep comfortably, Funk explains. “Of course, the mattress won't make your night sweats disappear entirely, but the mattress can help bring you some relief,” he notes. 

    Along the same lines, Burr says that a cooling mattress can be “an absolute game-changer” for someone with poor sleep quality attributed (at least in part) to sleeping hot. “The optimum room temperature is between 60° and 67° Fahrenheit,” he explains. “Unfortunately, some mattresses—especially memory foam—compress and trap your body heat. The trapped body heat can cause you to get hot and can negatively affect your quality of sleep.” 

    So how, exactly, does our body temperature change throughout the day, and what does that mean for our quality of sleep? “A person's body temperature will naturally peak and decline during a 24-hour period,” Loth explains. “The higher temperatures will be in the late afternoon and the lowest temperatures at approximately 5 a.m. Sleep usually begins when your body temperature drops, so a cooler room can encourage a person to fall asleep faster, stay asleep and have a more restful sleep.”
