The Best Cooling Mattresses for Hot Sleepers

Body temperature at night regulates your circadian rhythms that tell your body to go to sleep or that it’s time to get up for the day. If your body temperature throws off your sleep clock, you won’t get quality rest which can disrupt your quality of life and trigger health problems.

A National Institutes of Health study found a link between body heat at night and insomnia. Overheating at night can keep you from dropping off to sleep and can wake you from sleep leaving you struggling to get enough deep healing sleep.

This guide is aimed to help hot sleepers find relief. We define a hot sleeper as one that struggles to get or stay asleep because they feel excessively warm or those that frequently wake sweaty or unreasonably warm with no external factor for their disrupted sleep.

This guide contains our top five recommended cooling mattresses for hot sleepers including detailed reviews, plus construction and materials of cooler mattresses, the role of bed firmness in hot sleeping, and some accessories to help you get a cooler night’s sleep.

Cooling Mattress Reviews

The Best Value – Tuft & Needle Mattress

Tuft & Needle Bed
Construction:

The original Tuft & Needle mattress is a simple but well-made 10” two-layer foam mattress. The support core is 7” high-density polyfoam. The comfort layer is 3” high-density Adaptive® foam which is proprietary to the brand and infused with moisture-wicking graphite. The cover is Tactel® fabric that is strong, light, soft, and dries eight times faster than cotton for enhanced cooling.

Pros and Cons:

The obvious plus of the T&N original is the modest price tag, but there’s a lot going on here for a basic two-layer mattress. It’s well designed to be “universal” and appeal to wide range of sleepers. One con is that T&N’s original bed is only available in one firmness, self-rated at medium (5 on the firmness scale), but which buyers say feels more like a medium-firm 7.

Why Tuft & Needle Is Our Best Value Cooling Choice:

At a price point of less than $600, there’s some very nice cooling tech in this affordable bed. The foams in the bed contain cooling graphite and are open cell construction with gel beads that help prevent sleeping hot. The Tactel® cover is excellent for moisture wicking. Foam is known to be a warmer sleep material, but this is one to consider.

The Best Luxury – WinkBed Mattress

Winkbed mattress
Construction:

The WinkBed is a six-layer 14.5” hybrid mattress with advanced cooling tech. The triple support core has 2” of support foam under 7.5” tempered steel coils and a lumbar support pad. The triple comfort layers are 2.5” Micro Air-Springs® coils, and two inches of gel memory foam and hypersoft contour foam. There’s a Tencel® cooling cover and the optional coolControl™ base.

Pros and Cons:

The WinkBed is already cooler because it’s a hybrid with dual coils for heat-dissipating airflow. Another plus is the coolControl™ base that lets you cool or warm each side independently via a smartphone app to get the perfect temperature. The con is the cost. The bed is almost $1,300 without the cooling tech and almost $3,500 with it.

Why the WinkBed Is Our Best Luxury Cooling Choice:

Despite the steep price tag, WinkBed can be well worth the investment if you’re a very hot sleeper or have drastically different sleep needs from your partner. The bed comes in medium-soft, medium-firm, firm, and a Plus model for heavy sleepers. If you have picky sleep needs and a flexible budget, this cooling bed could be for you.

The Best Overall – Saatva Mattress

Saatva-Mattress-2
Construction:

The Saatva hybrid is a four-layer bed in 11.5” and 14.5” lofts. The height difference is the  3” Euro-top. The thinner version is intended for adjustable base beds. The support core is 7” steel coils. There are two comfort layers in both models. There are 4” high-gauge contouring pocket coils and a layer of high-quality memory foam. The cover is certified organic cotton.

Pros and Cons:

One pro of Saatva is that it’s not a bed-in-a-box and is never compressed. There are three firmness levels at soft, medium-firm, and firm to fit most sleep needs. Plus, the materials are eco-friendly and sustainably sourced. The cons are the moderate price at nearly $1k and if you don’t like the bounce of innerspring, this mattress might not be the one for you.

Why Saatva Is Our Best Overall Cooling Choice:

The Saatva’s dual coil layers optimize airflow for cooler sleep while the organic cotton cover wicks moisture. It’s a good blend of materials in a thoughtfully designed bed that dissipates heat while providing excellent comfort and support. Hot sleepers should consider the medium-and firm while heavy hot sleepers might prefer the firm.

The Editor's Choice – Sleep On Latex Mattress

SleepOnLatex-Pure-Green-Mattress
Construction:

The Sleep On Latex mattress has either one or two layers in lofts of 7” or 9” and is available in soft, medium, or firm. The combined support core and comfort layer in the shorter mattress is 6” Dunlop latex. The taller bed has a 6” core and 2” comfort layer, both all-natural Dunlop latex. There’s a 1” quilted layer of New Zealand wool and a certified organic cotton cover on both models.

Pros and Cons:

A pro of Sleep On Latex is that it’s all-natural latex which is cooler than many other materials. The latex is made with pinholes in the cooking process, so it circulates air through these aerations. The price is modest at less than $800 for either option. Two cons of the mattress are the 30-night mandatory break-in before you can return it and the low profile height.

Why the Sleep On Latex Pure Green Is Our Editor's Choice:

The Sleep On Latex mattress is a cross-section of cooling and low cost. The latex is excellent quality and all-natural for those that prefer a bed that’s not entrenched in chemicals. For hot sleepers, the bed is a good buy that meets many requirements, and the medium or firm should perform well. Heavy sleepers should look at the firm.

Special Cooling Mattress – Eight Sleep Mars+ Mattress

Eight Sleep Mattress
Construction:

The Mars+  is Eight Sleep’s premium mattress. It’s got four layers in an 11” design. The support core is 2” high-density support foam under 4” pocket coils. The dual comfort layer is 2” transition foam under 2” reactive foam. The cover is high-tech and monitors your sleep via iOS or Android app. It is compatible with three smart home hubs and monitors your sleep temp.

Pros and Cons:

With Mars+, a big plus for hot sleepers is you can turn down the AC at night to sleep cooler without freezing out your partner. The bed tech monitors temperature and can be set to warm or cool either side. One con is that the bed only comes in medium-firm, so heavy and hot sleepers might not have enough support on the mattress.

Why the Eight Sleep Mars+ Is Our Special Cooling Mattress Choice:

The tech in the mattress lets you set smart alarms that wake you at the ideal time based on your circadian rhythms. The hybrid’s coils enable cooler sleep, and the smart cover tracks ambient room temperature and sleep quality. The upper foam layer is latex-like and sleeps cool, and the monitoring tech can help you find your best sleep.

What Are Cooling Mattresses Made Of?

You sleep better if the room is a bit cooler at night. The National Sleep Foundation recommends you set your thermostat between 60-67o F at night. But lowering the room temperature won’t necessarily cool you enough if you’re a hot sleeper. One factor in restless, sweaty sleep is the materials inside your mattress. Unfortunately, some materials just sleep hotter than others.

How hot or cool a mattress sleeps is determined by either the heat retention or heat dissipating qualities of the material and the bed’s architecture. Heat retention is caused when the material lets you sink in and reflects your body heat back at you. The deeper you sink into the materials and the more prone they are to retain heat, the hotter you will sleep.

Here’s how these common materials interact with body heat:

  • Coils – Innersprings are a cooling sleep component because they are coils of wire with lots of space between for air to flow in and around and cool the bed.
  • Latex – Natural latex sleeps cooler than synthetic latex, and as its made with pinholes, these beds circulate air and facilitate moisture-wicking, both of which cool you.
  • Basic Polyfoam – Basic foam is a hot-sleeping material made of petrochemicals that warms because there’s no airflow, so heat cannot dissipate.
  • Basic Memory Foam – Standard memory foam has no airflow and is hotter than basic polyfoam because it lets you sink in and acts as a heat insulator.
  • Gel-infused Foam – Gel or gel beads may be infused into memory foam, and these absorb heat to pull it away from your body resulting in cooler sleep.
  • Advanced Polyfoam – Some evolutions in polyfoam promise to sleep cool, but reviews are mixed. Very hot sleepers should look to other materials that perform better.
  • Advanced Memory Foam – Open cell memory foam and infusions with graphite, copper, or other next-gen materials sleep cooler than traditional or gel foams.

Mattress construction affects cooling

How a bed is built, and the materials inside affect how well it cools. The temperature regulation or neutrality of a bed depends greatly on airflow. The flow of air is better with innerspring, hybrid, and latex. Sinkage affects heat, and that’s due to the thickness of comfort layer(s) and their composition.

Here’s a quick glimpse at the four major types of mattresses and how they affect hot sleepers.

  • Foam – These are the hottest of mattresses that insulate and reflect heat. Open-cell, gel, graphite, or copper-infused foams perform better as do firmer foam construction.
  • Latex – This material is comfortable and cooling. Natural latex cools better than synthetic and look for a latex bed constructed with little or no polyfoam for the coolest sleep.
  • Innerspring – Coil beds usually have a comfort layer made of polyfoam or memory foam. Look for a bed built with advanced foam or with a latex comfort layer.
  • Hybrid – Hybrid have pockets coils for airflow and then foam or latex comfort layers. Look for beds constructed with next-gen foams or natural latex comfort layers for cooler sleep.

How Does A Cover Affect Mattress Cooling?

The cover surrounds the stack of mattress materials, protects it, and is the surface you’ll constantly feel, so ensuring it cools and comforts is of great importance. The mattress cover can absorb and retain heat or may trap and dissipate it or may even convert heat to healing infrared light.

New cooling fabrics are coming onto the market constantly, many gleaned from the athletic and outdoor sports textiles industry where temperature regulation is vital. Some considerations when looking at mattress covers include:

  • Non-quilted covers – These are thin and allow you to interact directly with the comfort layers of the bed. A thin, all-natural or moisture-wicking option can keep you cooler than a low-quality synthetic or polyester product.
  • Quilted covers – These are thicker and may be warmer as a result. Look for cooling all-natural wool and avoid any that are quilted with polyfoam or standard memory foam inside which can heat you up excessively.
  • Phase-change materials – This material is designed to absorb body heat and store it to keep a constant temperature but may not sleep as cool as promised.
  • Cooling fabrics – Some cooling fabric to look for include thermoreactive Celliant® that turns your body heat into healing infrared light. Silver, copper, Lycra® and Lyocell are also beneficial in mattress covers for hot sleepers.

How Do Firmness and Sinkage Affect Hot Sleepers?

Firmness and softness are two unique concepts in a mattress. Firmness is determined primarily by the support core and softness by the comfort layers. A firmer bed is often a cooler sleep surface because you are pushed up to the top of the sleep surface and body heat doesn’t reflect back on you.

With comfort layers, the softer and thicker they are, the deeper the contour, and the more hug your body gets from the mattress. This can feel nice but it can trap your body heat and reflect it back onto you, making you sleep hotter than you want.

Sinkage into a bed can be driven by the support core and comfort layers together. The less firm the support core and the softer the comfort layers, the more likely you are to sleep hot. The lighter weight you are, the less firm of a bed you’ll want, but this can be problematic if you sleep hot.

Conversely, heavy people need a firmer bed and tend to sleep hotter. If you’re a hot sleeper and need a softer surface, you should consider a coolControl™ WinkBed or one of the accessories listed below so you can get the comfort you need without overheating.

Accessories for Cooler Sleep

If you just bought a new cooling mattress but it’s still not as chill as you want, you may want to add accessories to regulate temperature with greater accuracy. Here are some products that may help.

  • BedJet® – The BedJet cools your bed with air infused onto the sleep surface of the mattress. A single-zone BedJet is about $300. You can get a dual zone for about $700 that also tracks biorhythms for better sleep. The dual zone can warm or cool either side independently.
  • ChiliPad™ – The ChiliPad is a mattress pad that cools by circulating water through microtubes in the surface. The single-side model costs $450, and the dual about $1,000. You can cool either side of the bed to keep hot sleepers cool. It also warms if your partner runs cold!
  • BedFan – The bFan® is a lower-cost version of the BedJet. It’s a fan built to snug up to the side of the mattress and vent cool air under your covers. It runs about $150 but is often sold out due to immense popularity.
  • Purple Bamboo Sheets – Mattress maker Purple offers cooling bamboo fiber sheets for better sleep. Some microfiber products, like Sheex, are quite cooling and feature next-gen materials like pro-ionic copper. These cost $115-200 for queen size sheets.
  • Cooling Mattress Pad – There is an array of cooling mattress pads on the market. Be sure to carefully read reviews and look for materials like advanced-cooling gel, bamboo, or charcoal-infused materials.
  • Cooling Pillows – As with pads, there are a plethora of pillows on the market that promise cool sleep. Look for ventilated designs, gel, bamboo, or those with a porous architecture that encourages airflow and heat dissipation.
