It’s not easy to fall asleep when sweat is rolling off you in the fabric sauna your bedroom has morphed into.

However, one often overlooked key ingredient for good sleep is maintaining a cooler temperature in your bedroom. As someone who tends to sleep hot myself, I’ve tested many cooling products over the last decade, with varying degrees of success.

The good news is that whether you’re kept awake by warm weather, hot flashes, or just tend to sleep hot, there are effective ways to cool down your body and bed temperature.

In this article, I’ll be discussing two different ways to keep your bed and body cooler at night: high-tech bed cooling systems that work all night long, and cooling mattress pads that are designed to be breathable or to help wick body heat away.

If you just want a cooler surface to fall asleep on, a more breathable mattress pad or topper might be all you need. But if you’d like powerful or targeted cooling that lasts all night, one of the active bed cooling systems might be a better choice.

Overview of the cooling mattress pads and systems

Eight Sleep Pod 3 Cover

Price: $$$$

The Eight Sleep Pod 3 cover is my top pick in the cooling mattress pad category. It’s an intelligent bed cooling system that will reliably combat your body heat buildup and create a consistently cool surface to sleep on all night long. The base unit cools (or warms) water that flows through channels in a robust mattress pad. An accompanying app personalizes your experience as the system learns from the sleep tracking data. With a temperature range of 55° – 115° Fahrenheit (12.8° – 46.1° Celsius) and dual-zone controls, you and a partner can independently control your side of the bed. While the price puts it in the luxury category, it’s a worthwhile investment for unbeatable bed cooling.

BedJet 3

Price: $$$

The BedJet 3 is my top choice if you’d like a programmable bed cooling system that cools with air rather than water. It works with a forced air system that pumps air either inside a boxed cloud sheet or directly under your covers if you prefer. It has excellent fan speed and temperature controls, with a good range of 66° – 104° Fahrenheit (18.9° – 40° Celsius). It’s fully programmable, with multiple timers that let you set the fan speed and temperature at different points in the night.

Slumber Cloud Performance Mattress Pad

Price: $$$

The Slumber Cloud mattress pad is designed to absorb your body heat and wick away moisture. Using the temperature regulating ‘Outlast’ material that was originally designed for NASA, it’s a good option if you just want a fabric mattress pad that feels cooler rather than one you need to plug in. Just be aware that it has its limitations – if you stay in one position all night, your body heat will eventually win the battle. It’s still a good choice though as the material will feel cool for longer than most standard mattress pads.

Molecule Triple Zone Pro

Price: $$$

The Molecule Triple Zone Pro is the most breathable memory foam mattress topper I’ve slept on. It’s air engineered to have an open-cell structure, which creates more space for air to flow than is found in standard memory foam toppers. It provides a soft surface to sleep on, so this is a good option if you like the soft feel and cushioning of memory foam, but don’t want to overheat at night. Like the Slumber Cloud, there’s no active cooling though, so it will start to feel warm if you lie in one position all night.

Leisure Town

Price: $$

The Leisure Town is an affordable mattress pad that’s more breathable than most other low-cost mattress pads containing artificial fill. The fill is a down alternative, and it comes with a soft cotton cover. It does feel cooler to lie on than many budget mattress pads and will add a comfortable layer of soft padding to your bed. Once again though, the lack of active cooling means it won’t feel cool all night. For the low price, it’s a reasonable choice though as long as you don’t have serious heat to contend with.

Comparison tables

In the table below, you can see how I rate the cooling pads and systems out of 10 in key performance areas: cooling effectiveness, setup and cleaning, comfort, and durability.

The cooling effectiveness is based on two points: how well they cool me on hotter nights, and how long I feel cool for after initially getting into bed. Those with active cooling naturally score higher because they cope better with the heat buildup from my body.

For cleaning and maintenance, the toppers and pads are quick to install and don’t require much maintenance beyond a wash or spot clean. The BedJet 3 and Eight Sleep Pod Cover require more effort to install as they come with separate parts. Both need some periodic maintenance, which is quick and easy to do.

The comfort is based on how they alter the existing mattress in terms of the surface you sleep on. The durability is based on how long I’ve had them without any faults occurring or flattening under my weight over time.

The first four blue links will take you to the company websites, and the last one to Amazon.

In the next table, you can see which ones tick some of the key boxes I look out for when using cooling mattress pads and bed cooling systems.

Note that only the Eight Sleep and BedJet 3 have a temperature range because the other three don’t involve any tech, so can’t be programmed to a set temperature.

The cooling systems and mattress pads in detail

1. Eight Sleep Pod 3 Cover

The best cooling mattress pad overall, with an intelligent system that adapts to your temperature preferences and habits

In the photo above, I’m setting up the Eight Sleep Pod Cover 3 for the first time, adding water to the system. Note how the cover encases my mattress, but I also put my own mattress protector and bedsheet over it to sleep.

The Eight Sleep Pod 3 Cover is the most advanced and effective bed cooling system I’ve tried in the many years I’ve been testing them. I got mine in May 2023, and have been loving it so far, especially during heatwaves we had in June and early September.

What sets the Eight Sleep apart is its ability to keep you and your bed cool throughout the entire night. Unlike other mattress pads that claim to be breathable but often fall short in hot weather, this system is capable of combatting the natural heat buildup caused by your body. It really does create a cool and comfortable sleeping surface that stays cool until you turn it off.

The setup is quite straightforward: you have a base unit next to your bed filled with water, which then circulates through thin channels in the comfortable mattress pad. It’s compatible with various mattress sizes, making it a versatile option for many people.

To personalize your cooling (or warming if you prefer) experience, you download an accompanying app and input your preferences. The app provides initial temperature recommendations for different sleep stages, but the real magic happens when the system starts learning from your sleep and your habits. It automatically adjusts to optimize your sleep environment, ensuring a better night’s rest.

With a temperature range of 55° – 115° Fahrenheit (12.8° – 46.1° Celsius), you can program the Eight Sleep Pod Cover 3 to cool or warm your bed, and change temperatures throughout the night.

In the photo below, you can see the user-friendly app of the Eight Sleep. I usually set it to be very cool to fall asleep and then warm to wake up. You can also see how I’ve tucked the base unit between my nightstand and the bed. I’m still experimenting with different positions for it though, and probably prefer to have it on the other side of the nightstand.

If you share a bed with a partner and have different temperature preferences, the dual-zone option with separate app controls is a game-changer; one of you can sleep on a cool surface, while the other side is warm. My partner and I have different preferences, and it’s worked very well in letting us both control our own side of the bed without worrying that the other will complain it’s too hot or cold.

Additionally, the mattress pad doubles as a sleep tracker and monitors various metrics like heart rate, breathing rate, and heart rate variability. While I personally take some of the sleep stage measurements with a grain of salt, and try not to get too caught up checking them every day, I do find the heart rate variability information helpful when planning my workout intensity.

It’s important to note that the Eight Sleep Pod Cover 3 falls into the luxury category with a high price point. On top of that, there’s an ongoing subscription required for at least the first year to access the intelligent features. However, if you’re willing to make a significant investment in your bed cooling, this system is well worth considering.

A key point to bear in mind is that you’ll need to find some space next to your bed for the base unit as it’s taller than it is deep or wide. Fortunately, you only need one of them even for the dual-zone functionality, but you’ll need to get used to it sitting next to, or behind, your nightstand.

In the photo below, you can see the base unit, power cable, and instructions. The little white piece is for draining it if you need to move the cover.

Another minor criticism is that the fan in the base unit does make some noise when it’s making significant temperature changes. For most of the night, the fan runs very quietly though. Since I sleep with earplugs or headphones every night, I don’t hear anything at all from it.

In my experience, the Eight Sleep Pod Cover 3 has eliminated those uncomfortably warm spots and allowed me to sleep soundly, even without air conditioning on hot and humid nights.

If you’re someone who prioritizes quality sleep and has the budget for it, I highly recommend giving the Eight Sleep Pod Cover 3 a try. It’s a superb cooling system that has the potential to significantly enhance your sleeping experience.

Warranty / trial period

You can return the Eight Sleep Pod Cover 3 if you’re not happy with it within 30 days for a full refund. It comes with a two year limited warranty, and you can also purchase a higher subscription to get a five year warranty.

Price

There are two prices to consider: the initial cost and the membership subscription.

The cost depends on the bed size, ranging from $2,095 for the full up to $2,395 for the Cali King.

The standard subscription is $15 per month, and the plus is $24 per month if you want the five year warranty. After the first year, you can cancel the subscription if you prefer and only use the manual settings.

Pros

• Active cooling and/or warming all night.
• Excellent temperature range.
• Good app controls.
• Single or dual zones.
• Comfortable padding.
• Robust design.
• Sleep and health tracking.
• Vibrating and/or temperature alarm function.

Cons

• Makes a fan sound.
• Need space next to the bed for the base unit.
• You need to add distilled water every 2-3 weeks (the app tells you when).
• High price point.

2. BedJet 3 Climate Comfort

The most effective fan-based bed cooling system, giving you control over the fan speed and temperature

In the photo above, I’m using the BedJet 3’s snazzy remote control. Note how you can adjust both the fan speed and temperature to adjust the feel of the airflow.

The Bedjet 3 is my top pick if you’d prefer a bed cooling system that works with cool air rather than water. It has a sleek design and provides effective, fast, and targeted cooling all night long. I used mine for several years before giving it to a friend when I moved country, and it was a huge help in the warm summer months.

It’s made so that it can be quickly installed with any bed size and mattress, and comes with easy-to-understand instructions. You can choose to have cool air blowing gently over your body, or inside a boxed top sheet. So it will cool both you and your bedding, helping wick away the heat which gets trapped under your covers.

If you sleep with a partner, you can either share the cool air or keep it to just one side. There’s also the option of a dual-zone version for independent temperature control. With the double setup, you’ll get two remote controls so you and your partner can control the temperature on your side. There’s also an app if you’d rather control it with your smartphone.

The remote control has a color screen, and you can use it to adjust a wide range of settings, such as the temperature, fan speed, and auto-off timers. You can also program it to change temperatures automatically during the night. One of my favorite things about the BedJet 3 is just how much flexibility it gives you to adjust the temperature, air speed, and direction of the airflow.

You can also use the BedJet as a heating system in colder weather. I found it to be more effective and energy efficient than heated bedding, and it also heats your bed much quicker. If you have dual zones, you could even have cooling on one side of the bed and heating on the other – if you and your partner have very different temperature preferences.

One downside to consider is that you need to keep the base unit somewhere. I could tuck it under my bed as you only need a clearance of six inches. If you don’t have that, you’ll need to keep it next to the bed instead. At least you can get it under some bed frames though, compared to the Eight Sleep Pod which is unlikely to fit under any bed.

In the photos below, you can see two ways I set up the BedJet in my previous bedroom. In the first photo, I’ve placed the base unit next to the bed, and I’m demonstrating how the air flows from the tube into the cloud sheet so you have cool air over your whole body.

In the next photo, I put the BedJet 3 under the bed, which is more convenient if you have six inches of clearance for it. There’s no cloud sheet in that photo, so the air is targeted toward your feet.

Another potential issue is that the fan does make some noise, which is fine if you like fan sounds. It’s quite a soft hum on low to medium speed settings and pleasant to have in the background.

But if you need complete silence to sleep, the noise on the highest speed setting might be too much. Personally, I rarely used it on the highest speed settings anyway, as it’s effective on gentler settings. Note that it is louder than the Eight Sleep Pod base unit.

Overall, if you’d like an active cooling system that will reliably keep you cool and comfortable throughout the entire night, the BedJet 3 is an excellent choice.

Warranty / trial period

It comes with a 60 day trial period. They have an extended two year manufacturer’s warranty and will fix or replace any parts if needed.

Price

At the time of writing, the BedJet 3 costs $599 on the company’s website. If you want two units with the cloud sheet, the queen size is $1329 and the king is $1349. They regularly have sale prices listed though, which are typically considerably lower than those starting prices. For example, in mid August, the single unit was just under $450, with the queen and king both under $1000.

If you sleep alone or share your bed, and one of you is fine with the ambient room temperature, you can save money and just get the single unit to adjust the temperature on one side.
