If you’re a hot sleeper looking for a cool place to slumber, you want the best cooling mattress to take your nights from roasty-toasty to comfy-cool.

For some people, sliding between cool, crisp sheets at the end of a long day is pure bliss. But if you tend to run hot, you may find yourself disappointed and uncomfortable when your bed quickly goes from just right to way-too-hot. 

Fortunately, advanced materials with cooling technology may help hot sleepers stay comfortably cool. Here are our best cooling mattresses for 2022 and beyond.

Best Cooling Mattresses for 2022

Your core body temperature drops by a couple of degrees when you sleep. As you shed that heat into the environment, certain types of bedding can trap the warm, moist air. Along with cooling sheets and blankets, a cooling mattress may help keep you from overheating at night.

Best Cooling Mattress for Hot Sleepers Overall: Casper Nova Hybrid Snow Mattress

If you’re too warm at night and believe your mattress might be the culprit, a hybrid mattress with cooling technology may be just the thing to help you sleep comfortably. 

With a cooling cover, HeatDelete™ technology, and our very best AirScape® 3, Casper’s Snow Technology™ is our most innovative solution to nighttime overheating.

Best for:

  • Lighter- and average-weight sleepers
  • Back sleepers
  • Those who prefer a softer mattress

Best Cooling Memory Foam Mattress: Casper Original Mattress

Memory foam mattresses can be supremely comfortable, but they also have a reputation for sleeping hotter than innerspring or hybrid mattresses. That’s because the dense structure of some memory foams may not allow for maximum airflow in the way that a mattress with springs would. 

So what do you do when your need for support and comfort clashes with your need to keep cool?

If you’re looking for the comfort of memory foam but also want a cooler sleep experience, Casper’s Original Mattress™ — our most popular mattress — provides the perfect combination of support, cooling, and comfort. 

Best for:

  • Those who want the comfort and support of memory foam 
  • Hot sleepers who need a memory foam mattress with cooling technology

Best Cooling Hybrid Mattress: Casper Wave Hybrid Snow Mattress

If added support and responsiveness are important to you, or you’re a heavier-weight sleeper, a hybrid mattress could be the right fit for your sleep needs. 

A hybrid mattress combines memory foam, latex, or gel with an innerspring system. You get the comfort and pressure point relief of memory foam with the support, breathability, and responsiveness of inner springs. Hybrid beds often include:

  • Pillow top: A few hybrids include a one- to two-inch pillow top that is sewn on top of the comfort layer to provide additional cushioning.
  • Comfort layer: This three- to four-inch layer is made of cushioning materials like memory foam, latex, and cool-inducing gel. 
  • Support core: The support core gives hybrid mattresses the bulk of their height and provides extra spinal support with seven to eight inches of pocket-wrapped coils and springs.
  • Base layer: This one-inch base layer (usually made of foam) provides padding, sturdiness, and stability.

If extra support combined with premium breathability sounds like the perfect fit for you, our Casper Wave Hybrid Snow Mattress may be the solution to your nighttime comfort and cooling needs. 

Best for:

  • Average- to heavier-weight sleepers
  • Those who prefer a firmer mattress

Best Budget Cooling Mattress: Casper Element Mattress®

Good news! It’s possible to find a mattress that will keep you cool and comfortable all night even when you’re on a budget. 

Although some foam mattresses sleep hotter due to the density of their foam materials, our most budget-friendly mattress, the Casper Element Mattress®, features AirScape®, a foam layer with thousands of tiny perforations that help keep you cool all night.

Best for:

  • Hot sleepers looking for cooling comfort and long-lasting support
  • Those who want quality and cooling at a budget price point

Best Cooling Mattress for Hot Side Sleepers

If you’re a side sleeper who’s constantly kicking your covers off in the middle of the night to keep cool, a cooling mattress with the right amount of support is a must. A side sleeper’s main concerns are getting the neck, hips, and shoulders properly aligned to prevent strain. 

We recommend a medium-firm mattress for most side sleepers. A too-soft mattress may sag, causing improper spinal alignment. A medium-firm mattress molds comfortably to the curve of your body while also providing enough support to keep you from sinking.

Our Casper Original Mattress™ and Casper Nova Hybrid Snow Mattress are excellent choices for side sleepers in need of nighttime cooling.

Casper Original Mattress™ — Best for:

  • Average-weight side sleepers
  • Those who prefer memory foam but also need cooling technology

Casper Nova Hybrid Snow Mattress — Best for:

  • Heavier-weight side sleepers
  • Those who need a firmer, more supportive mattress

Best Mattress for Sweaty Sleepers

Need a mattress that may help you stop perspiring at night? No sweat! 

It’s not unusual to wake up sweaty on occasion if your room is too warm, your bedding is too heavy, or you’re dressed in extra-warm jammies. But if you regularly wake up hot and damp, a mattress with cooling technology may help.

These picks for sweaty sleepers are also the best mattresses for hot flashes. So if you frequently wake up at night feeling like you’ve just stepped out of a steamy sauna, these mattresses might help you keep your cool.

Casper Wave Hybrid Snow Mattress — Best for:

  • Lighter-weight sleepers
  • Those who prefer a softer mattress

Casper Nova Hybrid Snow Mattress — Best for:

  • Heavier-weight sleepers
  • Those who like a firmer, more supportive mattress

Mattresses for Hot Sleepers: Benefits of Cooling Technology

It would be natural to wonder whether cooling mattresses are really all that. Our extensive research and testing during the creation of our Casper Snow TechnologyTM led us to one simple conclusion: Yes, the right cooling mattress can make a big difference! Let’s take a look at a few of the benefits of cooling mattresses.

  • Better sleep quality — A cooling mattress can improve your sleep by helping to disperse heat, drawing it away from your body instead of allowing it to concentrate under the covers. (Pro tip: Casper’s HeatDelete™ Bands are like thermal highways that effectively keep you from overheating for up to 12+ hours.)
  • Lower air conditioning bill — If you don’t have to compensate for an overly hot mattress, you can set your thermostat at a more budget-conscious temp.
  • Reduced night sweats — A cooling mattress may reduce night sweats, helping you sleep cool and dry. In fact, the Casper Wave Hybrid Snow Mattress is designed to remove 34% more heat from under the covers. 

Casper’s 4D Sleep Technology™ is our proprietary combo of materials designed for temperature control and ultimate comfort, and it’s featured in every single one of our mattresses. 

What are the four dimensions of great sleep? We’re glad you asked. The sleep scientists at Casper LabsTM carefully crafted a formula that addresses every dimension of a great sleep experience.

Casper's 4D sleep technology
  • Alignment — Our Zoned Support™ (plus gel pods included in select Casper mattresses) helps prevent discomfort.
  • Temperature — AirScape® prevents overheating.
  • Touch — Our Casper Signature Feel™ helps you fall asleep faster.
  • Time — Rest Index Testing™ ensures all-night comfort.

How Do Cooling Mattresses Work?

Cooling mattresses work by drawing heat away from your body — no big surprise there. But how do they do it?

The average human body temperature of 98.6 degrees Fahrenheit is actually, well, pretty darn warm. When you crawl into bed and get under your blankets, the warmth from your body may get trapped between your mattress and covers, which makes your bedding warm up. 

It’s a dynamic many sleepers are all too familiar with: You kick your covers off when your bed gets too warm, then drag them back over you when you cool off again. And you may repeat that frustrating cycle all night long. 

Cooling mattresses include components designed to help dissipate your body heat and prevent overheating that may disrupt your sleep. Casper’s Snow cooling technology includes a QuickCool™ Cover that helps ensure that your mattress is comfortable when you crawl into bed, HeatDelete™ Bands that direct heat away from your body throughout the night, and AirScape®, which helps ventilate heat with thousands of perforations.

How to Sleep Cooler

Humans are not cooled by mattresses alone! To help you stay cool at night, it’s important to set up your environment for success, too. Here are a few quick tips:

  • Turn down the thermostat — The ideal sleep temperature is between 60 and 67 degrees Fahrenheit, so turn that thermostat down before you retire for the night.
  • Use fans strategically — Ceiling fans and bedside fans help move the air around your room while you snooze. (Bonus: White noise!)
  • Create cross ventilation — Opening two windows can help keep the crisp night air flowing. If privacy isn’t an issue, keeping your bedroom door open can help the breezes flow, too.
  • Adorn your bed in cooling bedding — Breathable bedding is a must for allowing body heat to dissipate easily. Casper’s Hyperlite™ Sheets are crafted with 100% TENCEL™ Lyocell and a unique grid weave for maximum breathability.
  • Get a cool pillow — Pillows made from cooling materials can help prevent the need for flipping your pillow over to the “cool side” all night long. The Casper foam pillow uses our AirScape® perforated foam to draw heat away.
  • Chill out with a cooling mattress protector — A breathable mattress protector may also help move hot air away from your body to keep you cooler. Casper’s mattress protector features a spacer knit design for maximum airflow.

Cooling Mattresses: All About the Breathability

No one ever got a good night’s sleep while having to kick the covers off multiple times per night. It’s also no fun (for you or your sleep partner) to wake up sweaty, tangled in damp sheets. 

That’s why we created our cooling mattresses. They’re designed to maximize airflow and move warm air away from your body, keeping you comfortable all night long. Because we give a sheet.
