Best Cooling Mattress for Hot Sleepers

If you share the bed with a partner, you may be familiar with sleep disturbance due to their tossing and turning. A bed with low motion transfer is able to isolate movement at the source and prevent it from traveling across the bed. Here at Sleepopolis, we evaluate motion transfer in every mattress we review using a seismometer. This test involves dropping a 10-pound steel ball onto one side of the mattress from three different heights. A seismometer on the other side of the bed measures the disturbance and displays the results in a graph. The larger the lines on the graph, the higher the motion transfer, and the more likely you are to feel a restless partner’s tossing and turning.

I found pretty average results when I performed the seismometer test on the Helix Midnight Luxe. The lines on the graph weren’t too large, and they were compacted close together, indicating the motion doesn’t ripple too much. However, I was a bit skeptical of the results, so I tried a more visual test– the red wine test. I placed a glass of red wine on one side of the bed and then tossed and turned on the other side. If the wine glass stands strong and the liquid doesn’t move, then we know the bed can isolate motion well. However, the wine glass tipped over and spilled wine onto the mattress.

These results combined with the seismometer results tell me the Helix Midnight Luxe isn’t the best at isolating motion. If you’re a light sleeper, you may feel your partner moving at night.

I was extremely impressed by how supportive the Helix Midnight Luxe felt. Every layer of this bed was designed to be comfortable while still promoting proper spinal alignment. The support layer is constructed from 1,000 individually wrapped coils that are zoned for support. This means the coils fluctuate in firmness depending on where the sleeper needs the most support. Under the coils is the base layer made from DuraDense foam, which keeps the mattress sturdy and prevents the sleeper from sinking in too far. When I laid down on the Helix Midnight Luxe, I felt super supported on my back and side. I could see sleepers with back pain finding great lumbar support, which can help provide some relief. I even think this mattress is supportive enough for back and side sleepers weighing over 250 pounds.

When I evaluate a mattress for cooling, I first take a look at its materials and construction. This hybrid mattress includes individually wrapped coils, which allow for plenty of air to flow through the bed without getting trapped. The gel foam in the pillow top and Copper Gel Memory Foam in the comfort layer are two more materials that help dissipate body heat and keep the sleeper cool. The mattress comes with a breathable Tencel cover, which is a material known for temperature regulation. For an additional cost, you can purchase the GlacioTex cover for even more cooling.

Next, I test mattress cooling using a thermal gun. I use the thermal gun to record the mattress’s initial temperature and then it’s temperature after I’ve laid on it for five minutes. If the temperature increases by more than 15 degrees, then it has very poor cooling capabilities. An increase of 10 to 15 degrees indicates decent cooling, 5 to 10 degrees indicates good cooling, and less than 5 degrees indicates excellent cooling.

When I used the thermal gun on the Helix Midnight Luxe, I found a temperature increase of 3.3 degrees, which indicates excellent cooling. Considering all the cooling technology inside this bed, I’m not surprised by how cool it sleeps.

When I talk about edge support, I simply mean how strong the sides of the bed are compared to the center. If a bed has strong edge support, the edges will feel sturdy and supportive with minimal sinkage. Couples or people who like to spread out may want to pay attention to edge support, as strong edges allow sleepers to use the entire surface of the bed, which can make it feel larger. Strong edges can also reduce the chances of premature mattress sagging.

All four sides of the Helix Midnight Luxe have reinforced edges to prevent them from sagging. When I sat and slept directly on the edges, I felt very lifted and supported. At no point did I feel at risk of slipping off the bed. I think this mattress could work for anyone that wants to spread out, or for people with mobility issues who use the sides to get into bed.

We test pressure relief by rolling a specialized mat onto the mattress and laying on it in different sleeping positions. The mat is able to sense pressure and display the results in a graph using thermal imaging. Areas displaying blue and green indicate low pressure buildup, and areas displaying yellow and red indicate high pressure buildup.

When I performed this test on the Helix Midnight, I was pleased to see only blue and green on the pressure map when side and back sleeping. This means the mattress did a great job of cradling my most sensitive joints and preventing pain. I enjoyed the initial contouring and softness of the pillow top. These results are excellent, which is why I gave this bed 5 out of 5 stars for pressure relief.

As I mentioned before, I test motion isolation by dropping a 10-pound steel ball onto the mattress from different heights. A seismometer measures the disturbance and displays the results in a graph where the smaller the lines, the better the motion isolation.

When taking a look at the Nectar Luxe Hybrid’s seismograph, we can see some large spikes. Since this is a hybrid mattress with bouncy coils, this isn’t too surprising. I would say these are pretty average results. You may feel a partner getting in and out of bed, but I don’t think you’ll feel smaller movements, like typical tossing and turning.

When I tested the Nectar Luxe Hybrid, I was very impressed with its support system. The bed’s support system is an 8-inch layer of individually wrapped coils. These coils give the bed a bit of bounce while keeping the sleeper lifted out of the structure. The top layers of foam also work together to create a soft yet supportive surface that helps promote proper spinal alignment. This bed leans softer, yet the foams are supportive enough to prevent the sleeper from feeling the coils below.

The Nectar Luxe Hybrid contains cooling technology designed to keep hot sleepers cool. When I laid down on the bed, I immediately noticed the cool-to-the-touch quilted cooling cover. As a hybrid mattress containing coils, this bed has plenty of space for air to flow through, keeping it breathable. I used a thermal gun to measure the temperature increase after five minutes of laying on the bed and found it only heated up by 3 degrees. These are great results, and I think this mattress could be an excellent choice for anyone prone to overheating at night.

I was overall really pleased with the edge support on the Nectar Luxe Hybrid. When sitting directly on the edge, I noticed some slight sinkage, but not enough to be concerning. I felt even more supported when laying directly on the edge, and I thought the edges had the same level of support as the center. When I used a tape measure to see how much the layers collapsed beneath my weight, there was only 1 inch of sinkage.

When I performed the pressure map test on the Nectar Luxe Hybrid, I felt a lot of immediate cushioning around my lumbar region and shoulders from the soft foams. The pressure map displayed only blue and green, which means there wasn’t a lot of pressure building at the hips, shoulder, or back. I think most back and side sleepers experiencing pain in these areas should find relief on the Nectar Luxe Hybrid.

I think the Nolah Evolution is a great choice for couples due to its ability to isolate motion. Looking at the seismograph, there are very small lines with no abrupt spiking. This bed does contain bouncy coils, but the top layers of foam effectively absorb motion and stop it from traveling to the other side of the bed. You might feel your partner getting in and out of bed, but you shouldn’t be awoken when they switch sleeping positions.

When it comes to support, the Nolah Evolution performs outstandingly. The mattress’s main support system is the patented HDMax EcoSupport Coils. These coils help prevent the sleeper from sinking too far into the bed’s layers and help put the spine in neutral alignment. I found pressure relief from the two comfort layers and the transition layer, but I also thought they supported my joints quite well. An inch of high-density support foam under the coils adds an extra supportive boost and gives the coils something to bounce off of.

As a hybrid mattress, the Nolah Evolution contains individually wrapped coils that leave room for air to flow in and out of the bed, which helps with cooling. The two comfort layers make the bed sleep even cooler. The first comfort layer is made with Nolah’s ArticTex fibers, which are supposed to cool the foam down. The second comfort layer is made from Nolah’s AirFoamICE, which is infused with graphite to help with temperature regulation. I have not tested this bed with my thermal gun yet, so stay tuned for those results. Overall, I am very impressed with this bed’s cooling abilities and would recommend it to hot sleepers.

The Nolah Evolution has great edge support due to the 8-inch layer of HDMax EcoSupport Coils. Edge-Tech support foam is wrapped around the coils to help reinforce them and keep the edges solid. When I sat near the edge, I noticed a bit of sinkage, but I still felt supported and stable. I felt even more stable when laying directly on the edge, and I didn’t feel at risk of falling off the bed.

The Nolah Evolution is a true medium-firm mattress, which we typically recommend to sleepers with back pain due to the balance between pressure relief and support. When we take a look at the pressure map, we see all blue and green when back and side sleeping. The coils do a great job at keeping the spine aligned and reducing back pain. There’s also enough foam up top to cushion the hips and shoulder, so I’d recommend this bed to both side and back sleepers.

The results from our seismometer test left something to be desired. Looking at the graph, I see a lot of large spikes that don’t quickly dissipate, especially from the 8-inch and 12-inch drops. These aren’t the worst results I’ve ever seen, but they definitely aren’t the best. I think you’re likely to feel larger movement from a partner, such as getting in and out of bed.

The main support system in the DreamCloud Original mattress is a tall layer of individually wrapped coils. These coils add firm support to the bed and are tall enough to lift the sleeper up and out of the mattress. The top layer of gel memory foam has a slow response to pressure, so it’s more supportive than typical poly foam. When I laid on the bed, I felt most supported on my back. The foams were able to fill in and support my lumbar region, and the coils helped prop my spine into neutral alignment.

As I’ve mentioned before, hybrid mattresses are typically cooler than all-foam mattresses due to the inclusion of coils. This remains true for the DreamCloud, as it has an airy construction. Memory foam tends to trap heat, but the memory foam in this bed is infused with gel, which helps dissipate heat and keep the sleeper cool. When I tested the mattress with my thermal gun, I found a 7-degree temperature increase after laying on it for 5 minutes. This indicates great cooling abilities, so I think hot sleepers will be able to sleep nice and cool.

When I tested the edge support on the DreamCloud mattress, I felt both lifted and supported. When I laid on the sides of the bed, I didn’t feel like I was about to slip and fall off the bed. I was able to sit directly on the edge without too much sinkage. Overall, I’d say the DreamCloud’s edge support is super solid.

Despite being a firm mattress, I still thought the DreamCloud did a great job at cushioning the joints and relieving pressure. The mattress cover is quilted with foam, which adds some initial plushness. A layer of gel memory foam allows for a bit of sinkage and pressure relief at the shoulders and hips. When we take a look at the pressure map, we see pretty much all blue when back sleeping, so I think back sleepers with back, shoulder, or hip pain could find great relief. I do see a bit of yellow forming at the hips when side sleeping, so I’d recommend a softer mattress to side sleepers.

As I’ve mentioned before, the inclusion of coils in a mattress makes the bed bouncy and can sometimes allow for motion to transfer across the bed, thus disturbing the sleeper on the other side. When it comes to the Saatva, there’s not just one layer of coils but two. Therefore, I wasn’t surprised by the lack of motion isolation in this bed. The seismograph shows some harsh lines, so I think you’re very likely to experience sleep disturbance from a restless partner.

What the Saatva lacks in motion isolation, it makes up for in support. I gave this bed 5 stars for support because its coil-on-coil construction keeps the sleeper lifted up and out of the structure. The layer of memory foam in the middle of the mattress is zoned for support, so its firmness fluctuates depending on where the sleeper needs the most support. This layer also contains Saatva’s Spinal Wire which offers even more spinal support. Stomach sleepers typically need a lot of support to keep their hips propped up and prevent the spine from bending. I definitely think this mattress is supportive enough for stomach sleepers.

Because this innerspring mattress doesn’t contain a ton of foam, the chance of heat trapping is reduced. With two layers of coils, the Saatva has a ton of space inside for air to flow in and out, making the bed very airy and breathable. I tested this bed using my thermal gun, and I found a temperature increase of 9.3 degrees after laying on it for five minutes. This indicates good cooling, and I did feel pretty cool when lying on it.

The Saatva should be the standard when it comes to solid edge support. These edges were extremely sturdy and felt exactly the same as the center of the bed. I used a yardstick to measure how much the layers collapsed under my weight and found less than a half inch of sinkage.

For the pressure relief test, I tested the Luxury Firm model of the Saatva mattress. When we take a look at the pressure map, we see mostly blue and green, indicating low pressure buildup. This model could be great for back and side sleepers, but I would recommend the Firm model to stomach sleepers to prevent pressure building at the lower back.

When I performed the seismometer test on the WinkBed Plus, I found good results. This bed does contain coils, which can sometimes limit a bed’s ability to isolate motion. However, this bed was still able to isolate motion at the source. Looking at the graph, there are some large spikes, but they calm down pretty quickly. I think you’re likely to feel large movements from your partner, but I don’t foresee normal tossing and turning causing an issue.

The WinkBed Plus was designed to support sleepers who weigh over 250 pounds, so it’s naturally a very supportive bed. The mattress has a Euro pillow top that’s quilted with HD “anti-sag” gel foam, which provides initial support upon laying down. There’s also a layer of latex foam that’s zoned for support, meaning its firmness fluctuates depending on which parts of the body need extra support. If the bed wasn’t already supportive enough, it also contains a layer of individually wrapped coils for extra support and lift.

When we take a look at this bed’s construction, we find tons of space for airflow due to the pocketed coil layer. The mattress also has a Tencel cover, which is naturally cooling and breathable. There’s also a bit of gel foam in the Euro top, which helps dissipate heat in hot sleepers. The layer of latex foam also helps with cooling, as latex is a naturally breathable material. I haven’t tested this bed with my thermal gun yet, so stay tuned for those results. Overall, I’d say this mattress is a great pick for heavy hot sleepers.

I gave the WinkBed Plus 5 stars for edge support because it meets all my expectations for sturdy edges. The coil layer contains an Extra-Edge Support System that keeps the mattress perimeter super solid. Whether I sat or lay near the edge, I felt incredibly supported and stable. I don’t think the sides will sag prematurely, and you should be able to sleep right up to the edge without falling off. 

Since this bed was designed for heavy sleepers, I brought in a guest tester, Paulie, to help me out with the pressure map test. Paulie falls in the heavy weight sleeper category, so I thought he would be a better representation of what it’s like for heavy folk to sleep on this bed. When we take a look at his pressure map, we see mostly blue and green at the lumbar region when back and side sleeping, indicating good pressure relief. There is a bit more pressure building at the shoulders and hips when side sleeping, so those with preexisting shoulder or hip pain may want a softer mattress. Paulie carries most of his weight in his stomach, so stomach sleeping wasn’t the most comfortable for him. However, I think many heavy stomach sleepers will find relief on this mattress.

I was very pleased with the motion isolation on the Brooklyn Bedding Aurora Luxe. If we take a look at the seismograph results, the lines are relatively small and there’s minimal spiking. If you wake up very easily, you might be disturbed by a restless partner. However, I think most sleepers will be able to sleep soundly without feeling their partner’s movement. At the very most, you might feel them getting in and out of bed.

With high-quality foams and coils zoned for support, the Brooklyn Bedding Aurora Luxe mattress is incredibly supportive. Although the foams pull their weight, the coils are putting in the most work. These coils are 8 inches tall and feel softer and firmer depending on where the sleeper places the most weight and needs the most support. When laying on this mattress, I felt very secure and supported.

When it comes to memory foam, it has a reputation for trapping heat. However, certain materials can be infused into the memory foam to help dissipate heat and better regulate the temperature. The Brooklyn Bedding Aurora Luxe has a layer of gel-infused memory foam and a copper-infused layer that’s been treated with TitanCool, a phase change material that promotes airflow. The inclusion of coils adds even more airflow and breathability. When I tested this mattress with the thermal gun, I found a temperature increase of 5 degrees after laying on it for 5 minutes. This indicates good cooling, and hot sleepers should feel comfortable on this mattress.

The Brooklyn Bedding Aurora Luxe has solid edge support. When I sat on the edge of the mattress, I felt very secure and stable. I used a yardstick to measure how much the layers collapsed under my weight and found only 2 inches of sinkage. I think most sleepers will be able to sleep right up to the very edge of the bed while still feeling secure and supported.

When testing the Brooklyn Bedding Aurora Luxe for pressure relief, I chose the Medium model. If we take a peek at the pressure map, we see mostly blue and green at the hips and back when side and back sleeping, indicating low-pressure buildup. I felt the foams contouring around my joints when laying in these positions and overall felt really comfortable. However, I do see a bit of yellow forming at my shoulders when side sleeping, so I would recommend the softer model for side sleepers.

Based on the Bear Elite Hybrid’s performance in my motion isolation test, I think it’s an excellent choice for couples, especially if one or both partners tend to toss and turn. When we look at the seismograph, we see very small lines. The only noticeable spikes are from when the steel ball is dropped from the highest height, which represents a person jumping on the bed. If you sleep with someone else, you’re very unlikely to feel them moving on the other side of the bed.

I thought the Bear Elite Hybrid was super supportive thanks to its coil-on-coil construction. These two coil layers helped lift my body up and out of the bed. Not only was my spine supported, but I felt lots of support from the foam contour layer, which contains five different zones. The foam is softer and firmer depending on the zone, so each part of the body is adequately supported.

The first thing I noticed about the Bear Elite Hybrid was its cool-to-the-touch cover made from phase change material fabric, which is available for purchase upon checkout. Directly below the cover is a layer of copper-infused memory foam that helps dissipate body heat. Underneath is a comfort foam that promotes airflow, and finally the breathable coil layers. When testing this mattress, I could immediately feel the cooling technology at work. But just to be sure, I pulled out my thermal gun. I recorded a temperature increase of 10 degrees after laying on the bed for five minutes, indicating decent cooling. I think hot sleepers can find a lot of cooling relief on this bed.

The edge-to-edge coils inside the Bear Elite Hybrid gave me high expectations for the bed’s edge support. When I sat and laid down on the edges, I felt very secure. There was some sinkage when I sat on the edges, but it wasn’t enough to raise concern. I think this mattress could appeal to folk with mobility issues, as these sleepers rely on the edges to get in and out of bed.

When we take a look at the Bear Elite Hybrid’s pressure map, we see mostly blue and green at the back, hips, and shoulders when I was sleeping on my side and back. There is slight pressure building at the shoulders, knees, and lower back when I sleep on my side, but I don’t think this pressure is too alarming. Most side sleepers should sleep pain-free, but those with severe preexisting joint pain should make sure to select the Soft model upon checkout.

Looking at the seismometer results, I think the Leesa Sapira Chill does a good job of isolating motion. The lines on the graph aren’t alarmingly large, and the minimal spiking quickly dissipates. You’ll likely feel a partner getting in and out of bed, but normal tossing and turning shouldn’t wake you up.

When I laid down on this mattress, I felt incredibly supported. I could feel the foam layer contouring around my body and easing me onto the base layer of individually pocketed coils. These coils are zoned for support to promote optimal spinal alignment. I felt the most support when sleeping on my back. The foam filled in the space at my lumbar region, yet the coils kept my body lifted and prevented too much sinkage.

As the name implies, the Leesa Sapira Chill was designed for hot sleepers. When I first laid down on the mattress, I immediately felt a cool-to-the-touch sensation. Leesa says the mattress cover contains cooling fibers designed to keep the skin at 88 degrees. Within the mattress are cooling gel-infused foam and breathable pocketed coils. I used the thermal gun on the Leesa Sapira Chill and found a temperature increase of 6.3 degrees after laying on it for 5 minutes. This indicates good cooling, so I think hot sleepers will be really happy on this bed.

The edge support on the Leesa Sapira Chill was impressive. When I sat and slept directly on the edge, I felt supported and didn’t feel like I was about to slip off the mattress. I usually sink in the most when I place my entire weight directly on the edge, yet I barely sank in on the Leesa. I think this bed could be great for couples wishing to really spread out and use the entire surface of the mattress. 

I tested the Medium-Firm model and found impressive results when it came to pressure relief. If we take a look at our pressure map, we can see primarily blue with just a bit of green forming at the hips. I felt the most pressure relief when back sleeping, and I think people with back, shoulder, or hip pain could find a lot of relief on this bed. Side sleepers with very sensitive hip joints may want to opt for the Plush model, but I think most side sleepers will find nice pressure relief on this mattress.
