Why Purple Hybrid wins as best cooling bed for side sleepers

Purple makes some of the most unconventional mattresses on the market today. The hybrid model utilizes the same breathable Hyper-Elastic Polymer, combined with pocketed coils that add support, durability, and even more breathability. 

We think Purple is the best cooling bed for side sleepers because it offers a heck of a lot more airflow than most mattresses on the market, and it’s super pressure-relieving if you’re a side sleeper open to a bed with a unique feel.

  • The feel is one-of-a-kind and really comfortable if you’re open to an untraditional mattress feel.
  • It doesn’t incorporate any cooling tech, but it’s a cooling bed by design; it’s naturally incredibly breathable. The top layer offers airflow as it contains a ton of little air pockets, and the bed is really great at not retaining heat.

Why GhostBed Luxe wins as best cooling memory foam mattress

GhostBed Luxe is as much a memory foam mattress as it is a cooling mattress. What we mean by that is, the memory foam is there for support and pressure relief, but the cooling gel and other technologies are there to help regulate your body temperature effectively. Ghostbed Luxe is a top pick for the best memory foam mattress for hot sleepers. It’s also accommodating for any sleeper type, thanks to its medium firmness profile.

GhostBed Luxe’s best features

  • GhostBed Luxe has a layer of Ghost Ice on top of the gel memory foam to help with your core body temperature. 
  • The cover incorporates cooling fibers that make the mattress feel cold and is another contributing factor to its cooling feel.
  • It’s a thick foam mattress, standing at 13” tall. It’s best for petite to average-sized sleepers, but the thick construction makes it a decent option for heavy sleepers fixated on a foam bed. 
  • Another great thing about GhostBed Luxe is that Nature’s Sleep is always discounting it. So, while it looks relatively expensive on paper to some, they often have specials that make it more palatable.

Why Avocado wins as best natural & organic cooling mattress

Avocado is a luxury mattress made with pocketed coils and a number of eco-friendly, breathable materials, including organic latex foam. This allows for increased air circulation, which helps to dissipate heat, thereby keeping you cooler at night. We think Avocado is the best natural cool mattress for hot sleepers. Avocado is technically not designed to be a cooling mattress, but the firmness level and construction to naturally keep you at a comfortable temperature.

Avocado’s best features 

  • Avocado is made with two layers of material (three if you purchase the additional topper). It utilizes recycled steel pocketed coils, organic latex, organic cotton, and organic wool. 
  • Natural latex, like Avocado’s, is hypoallergenic and antimicrobial. It’s also perforated for airflow. 
  • The firmness level is also a huge reason why we like this bed for hot sleepers. By default, our editors consider Avocado to be a truly firm mattress around an 8 to 9 out of 10 on the firmness scale. Even if you add the optional pillow-top, Avocado is still a medium-firm mattress.

Why Loom & Leaf wins as best mattress for back sleepers

Loom & Leaf is a premium mattress brought to you by the folks over at Saatva. It’s their firm memory foam mattress offering, and it even comes in two different firmness options that are suitable for back and stomach sleepers.  

In the middle of this memory foam mattress, you can find a laminated cooling gel spinal panel that helps keep you cool while you sleep. This sets it apart from many memory foam beds that tend to have a hot-sleeping reputation. We also aren’t mad at the price of this bed, compared to other hotel-luxury mattresses on the market.

Loom & Leaf’s best features 

  • Its laminated cooling gel is made with the same material found in hospital burn units. We think it’s a nice touch to keep this memory foam bed on the cooler side of the sleeping spectrum. 
  • You can choose Relaxed Firm, which we rated a medium-firm, or Firm, which we rated a true firm. Either way, this bed will have a firmer mattress profile that will keep back and stomach sleepers properly supported during their sleep.
  • It’s not a hybrid, but it is about 12” thick, making it a suitable mattress for all body types, including some heavy sleepers.
  • Loom & Leaf is moderately priced, especially considering it’s a luxury bed.

  • How We Test The Mattresses

    The Slumber Yard has been around since the beginning of the bed-in-a-box craze. Our team has personally tested over 175 mattresses so far, and we keep more than 150 beds in our office so we can compare them (and take afternoon naps).

    When testing mattresses, we evaluate the following factors:

    • Construction: We cut mattresses open to see what’s inside and how it’s made.
    • Feel: We check if it has a stuck-in-the-mud memory foam feel, or if it’s more of a neutral foam or a plush pillow top, etc.
    • Firmness: We have our own firmness scale and evaluate how that may vary depending on your body and sleeper type.
    • Pressure relief: We test what’s the sweet spot for different body and sleeper types.
    • Support and how that changes by body/sleeper type
    • Edge Support: This is important for couples who share a bed. Would you roll-out of the bed or can you sleep confidently close to the edges?
    • Motion Isolation: We use the water glass test to see how the bed fares with motion transfer. This is another important factor for couples that don’t want to wake up one another when they move.
    • Temperature Regulation: We use a temperature gun to evaluate if the bed warms up, stays neutral or actively cools while you are sleeping.
    • Noise: This could be an issue in beds with coils or innerspring.
    • Off-Gassing: Some beds could have a smell for a few weeks after unpacking, and we try to warn you about it.
    • Company policies: We also take into account policies such as shipping, returns, trial period and warranty.
    • Value: We look at a bed’s price in the context of what it offers in terms of features and quality of materials and construction.

How To Find The Best Cool Beds For Hot Sleepers

Pay attention to construction and materials

We just want to talk in more detail about mattress construction and how it comes into play when you’re looking for a cool mattress.

  • Gel-Like Materials

    Infrequently used, but generally allow for great airflow. The Original Purple Mattress is the prime example here. It uses the company’s proprietary Hyper-Elastic Polymer as its top layer. It’s more of a neutral material in that it doesn’t heat up, nor is it cool to the touch.

  • Innersprings

    Traditional innersprings let in a lot of airflow. These are usually the support system for the mattress and can be buried in layers and layers of foam, which limits any effect that you might feel. The more spring you have the less overall material, and therefore the better the airflow.

  • Pocketed Coils

    Similar to innersprings, but the coils are wrapped in a light fabric. Still lets in plenty of air. These also have the added advantage of limited motion transfer, as compared to innersprings. It’s durable and does sleep cooler than poly foams.

  • Proprietary Foams

    Judge this on a case-by-case basis. We’ve tried some that sleep cool and some that are warm.

  • Cool Gel Memory Foam

    New-age memory foam with gel interwoven to remain cooler. It’s still memory foam, but tries to proactively keep you cool.

The Cover On Your Mattress Is Important To Cool Sleeping

Most people largely ignore the cover of their mattress, but it can be a key element in keeping you cool at night. The best mattresses for hot sleepers will have special covers to help cool you down. If you sleep hot, you should be looking for one of two types of covers.

  • Phase-Change Material

    This helps to pull away your body heat and cool you down. This phase-change material is becoming quite popular. It’s effective at keeping you cool and is actually cool to the touch, even when it’s hot out. It’s impressive stuff. You’ll even see it sometimes incorporated into foams.

  • Breathability

    If the cover doesn’t have a magical textile to keep you cool, then it should at least be breathable. That way you can feel the effects of the cooling gel memory foam or latex foam, for example. If the cover is too thick, it can absorb and retain your body heat, which will warm you up even more. As an example, if the cover on Purple mattresses wasn’t breathable, then you’d miss out on a lot of the cooling effects of the Hyper-Elastic Polymer. Testing breathability is fairly simple. Lift a portion of the cover off of the mattress and see how thin or thick it is and also how easy it is to blow air through it.

Combining Two Cooling Technologies

This is the Holy Grail of mattresses for hot sleepers or people with night sweats/hot flashes. If you get a cooling bed that has phase-change materials plus innersprings or pocketed coils, you’re in for an Arctic experience. It will be cool to the touch and get great airflow from the coils.

Do not get these beds if you sleep just kind of warm. They’ll be too cool of a mattress for your preferences. Do not get them if your sleeping partner is petite and runs cold. They will freeze to death. You should only consider one of the best cooling mattresses if you absolutely burn up at night. Sometimes we even see beds with coils, cooling memory foam, and a phase-change cover. That bed should be a really nice refuge for hot sleepers.

Avoid Softer Mattresses (Generally)

In general, a firmer mattress (usually for back sleepers and stomach sleepers) is going to sleep cooler than a softer mattress, simply because you sleep more on the bed rather than in it. We’ve tried plenty of mattresses that we expected to sleep more in the neutral range, but they ended up being warmer because either the cover wasn’t breathable or the mattress was on the softer end. If you need a more plush mattress, look for one that has a phase-change material in the cover. While the bed won’t be especially cool, it also won’t be alarmingly warm.

Best Cooling Mattresses For:

Back Pain

Both the Aurora Hybrid and the GhostBed are some of the best beds for hot sleepers who suffer from back pain. The Aurora Hybrid is a part coil part foam mattress that provides the stability of an innerspring mattress with the pressure relief of a foam mattress. The GhostBed is a cool gel memory foam that gives sleepers the benefit of pressure relief and cooling gel to avoid heat build-up.

Back And Stomach Sleepers

These types of sleepers usually sleep most comfortably on firmer, more supportive beds. Here is a list of mattresses that we think are viable options:

Side Sleepers

Most people sleep on their side. In fact, according to our research (over 2,000 people surveyed), about 68% of people identify as a side sleeper. Further, about 25% of people consider themselves a hot sleeper, although 50% of people report sleeping hot sometimes. Therefore, a good portion of people are hot side sleepers, so we thought it made sense to discuss them in greater detail. In no particular order, here are the best cool mattresses for hot side sleepers:

Combination Sleepers

Our top pick for the coolest bed for combo sleepers would probably be Purple Hybrid Premiere or Cocoon Chill’s soft option because they’re both rated in the middle of our firmness scale, which allows combo sleepers to switch between positions without having to compromise pressure relief or support.

Frequently Asked Questions
How much does a cooling mattress cost?

In most cases, for a queen mattress, the cost of a cooling mattress is about $1,500 after discounts. That’s a fairly reasonable price to pay considering most of these beds for hot sleepers are more luxurious.

Do cooling mattresses really work?

Some cooling mattresses work and some don’t. You can’t always trust marketing language when it’s on a mattress brand’s website. We recommend you look at mattress reviews to get perspective on how cool-sleeping a mattress actually is.

What kind of mattresses keep you cool?

A cooling mattress will usually incorporate two or one special kind of cooling technology. This may include a cooling cover and phase-change material, pocketed coils and a special breathable design like Purple, etc.

How can you cool down a mattress?

If you’re not ready to invest in an actively cooling mattress, mattress pads or toppers are an inexpensive way to stay cool at night. Memory foam tends to trap heat, so be careful with which one you choose. It’s also a good idea to think about what type of sheets you use –– jersey will often leave you waking up sweaty.

Do I need a cooling mattress?

Maybe, but there are numerous other factors that affect your temperature beyond the mattress. Your pajamas, sheets, and the room temperature all will affect how hot/cold you sleep. Even the bed’s firmness level is important. The softer the bed, the warmer it will generally sleep.

What is a “cooling cover” and how does it work?

A cooling cover is typically one with a phase-change material that uses a really neat chemical reaction to get colder when it passes a certain temperature. At a micro level, the cover actually liquefies to cool you down.

Do cooling mattresses really work?

Some do and some don’t. You can’t always trust marketing language when it’s on a mattress brand’s website. We recommend you look at mattress reviews to get perspective on how cool-sleeping a mattress actually is.

Which mattress does not produce heat?

Breathable mattresses like latex foam and hybrid beds typically produce the least amount of heat. Purple is also great at not retaining your body heat because of its gel-like, airy design. Memory foam beds have a reputation for retaining heat, but you can find some that incorporate cooling technology if you really like the material.

Can I buy a mattress in store or online?

We usually recommend purchasing online because brands have made the process extremely easy, and you typically get at least three months to try out your mattress when you purchase through an online retailer. Some will even give you a year and set up your mattress in-home for you, for free.

Can I try an online mattress in a store?

If you still want to check the mattress before it gets to your house, you could try brands like Nectar, Purple, Casper, Brooklyn Bedding, Bear and Tuft & Needle, that have showrooms or retail partners around the country. They even have store locator tools on their websites.
