The Best Cooling Mattress Pads & Bed Fans

Temperature is often overlooked as a cause of sleep problems, but it’s actually one of the key ingredients for a good night’s sleep.

Along with darkness, a falling temperature tells your body clock that it’s time to sleep. And nobody finds it easy to sleep with sweat trickling down their skin!

If you can control the room temperature, you’ve won half the battle. And a cooling mattress pad or bed fan can then help with some targeted body cooling.

From complete climate control systems to heat absorbing mattress pads, hopefully you’ll find something in this review that makes your bedroom a cool sanctuary of rest.

1. BedJet Climate Comfort For Your Bed

Most effective bed cooling system, with powerful cooling features

If you need something that will keep you cool throughout the whole night, the BedJet is the most effective bed cooling system I’ve found.

Made in a way which can fasten to any bed, you can either have cold air blowing gently over your body, or between a top sheet and comforter.

It cools both you and your bedding, dealing quickly with any heat and sweat that gets trapped under your covers.

If you and your partner have different preferences, there’s the additional option of having separate temperature zones, with dual controls for each of you.

There’s the choice of using either the simple remote control provided or the excellent smartphone App. And the App lets you get very specific about your cooling needs during the night.

You can program it to change temperatures as the night progresses, and turn off at the exact time you’d like. Then automatically turn on again in the morning at a different temperature.

What most impressed me is the huge amount of choice it gives you. Programmable cooling and heating, a wide range of fan speeds, normal and turbo settings, and dual zones. It just does it all, and does it very well.

The main downside is that it’s quite expensive, especially the dual zone version. So if you’re on a budget and just need a little extra cooling at night, one of the options below might be more suitable.

But if you have a serious problem with overheating, the BedJet will keep you significantly cooler than any other fan or cooling mattress pad.

2. Slumber Cloud Nacreous Cooling Mattress Pad

Most effective cooling mattress pad that absorbs body heat

The nacreous cooling mattress pad by Slumber Cloud attempts to keep you comfortable during the night by absorbing the body heat that builds up between you and the bed.

It works thanks to some clever technology that was originally designed for NASA.

It contains a special fabric called Outlast, which is made from thousands of tiny beads called ‘Thermocules’. The beads absorb your body heat, changing from a solid to gel as they do.

Outlast, the company that creates the cooling material, describe the effect like an ice cube in a drink.

The ice melts as it absorbs the heat of the drink, keeping it cool for longer. Similarly, the thermocules turn to gel as they take in your heat, helping you stay cool for longer.

I found it works really well compared to other cooling pads I’ve tried. And it’s significantly better than a normal mattress, topper or pad. It helped me feel more comfortable during some unbearably warm summer nights.

However, it’s important to note that it can’t do anything about the room temperature. If your bedroom is very hot, it won’t change that. What it will do though is stop you feeling like you’re lying on a fabric sauna.

For me, it’s the best cooling solution in the form of bedding. The BedJet might keep a larger surface area of your body cool with its air stream.

But the Slumber Cloud mattress pad is a good option if you want to reduce that unpleasant hot feeling that can build up underneath you during the night.

3. ChiliPad Cube

The ChiliPad Cube tackles the concept of bed cooling in a unique way. Along with the BedJet, it’s one of the few bed cooling products which can handle more serious heat problems.

The most important point is that it can keep you cool all night long, unlike most gel pads and fabric toppers which only work for a few hours.

It works by what’s essentially a water cooling system. It contains semiconductor technology, adjusting the temperature of the water as it flows through the base unit.

You place the mat on your bed, set the temperature you want, and cooled water will flow through the tubes buried inside the mat.

The mat and tubes are well designed so that you don’t feel them underneath you, and are durable enough to last the test of time.

The temperature range means you can use it for cooling or heating, with a range of 60° – 110° Fahrenheit (15.5° – 43° Celsius).

And with dual remote controlled units for larger bed sizes, you and a partner can have the exact temperature you need.

A possible issue for some people might be that it’s quite complicated to set up and maintain. It’s worth bearing in mind that you don’t just plug it in and forget about it.

Another criticism is that although the new models have quieter fans, they do still put out some noise. So if you’re easily disturbed by sound, you might find that an issue.

Overall, the ChiliPad is a clever device, and worth considering if you need something to keep you cool throughout the whole night.

4. Sleep Better Iso-Cool Cooling Mattress Topper and Cover

3 inch temperature sensitive memory foam topper with cooling cover

The Sleep Better topper and cooling cover is a good option if you want the extra comfort of memory foam, but with a little less heat than memory foam usually brings.

The reality, however, is that if you’re serious about tackling your problem with overheating, sleeping on top of memory foam isn’t the best start!

Memory foam retains your body heat as it molds to your shape, and doesn’t dissipate it so well.

That’s where the cover comes into play in this particular product though. It’s made from a luxurious 300 thread count cotton, with a generous amount of fiber-fill. And it contains the famous Outlast technology.

The Outlast material helps dissipate your body heat by absorbing it into thousands of microbeads. And when you cool down later in the night, it releases the warmth back to you.

It does feel cooler when you first get into bed. And for the first couple of hours, it’s better than sleeping on a normal memory foam topper or mattress.

But as the night goes on, it becomes less effective when your body heat and memory foam below slowly overwhelm the outlast cover. So if you tend to wake in the night in a pool of sweat, you might find it doesn’t quite do enough for you.

But if you only need a little extra cooling, and like memory foam, this 3 inch topper has that lovely ‘sleeping on a cloud’ feel to it. And the cover does help mitigate some of the usual heat.

Overall, it’s a very comfortable mattress topper which adds soft padding to your mattress, and helps regulate your temperature. But if you need serious cooling, memory foam isn’t the way to go about it.

5. Gel’O Cool Mat

A transportable cooling mat that dissipates body heat

The Gel’O Cool mat is a convenient option that you can place in any position under your bed covers.

If you sleep alone, you can use it vertically. Or you can place it horizontally so you and a partner can both benefit from the cooling under the upper body.

It works by dissipating the heat that gets trapped under your body to the parts of the mat you aren’t in contact with. That does mean that it lasts longer if you use it on your own rather than with a partner.

It’s easy to use as it doesn’t need any special preparation or an electrical outlet. But you can leave it in the fridge or freezer for a couple of hours before bedtime to boost how long it’ll last for.

I’ve found it does a good job of keeping me cool for the first 2 to 3 hours. After that, it struggles to dissipate your heat at the rate your body produces it.

That means you need to roll onto a different part of the mat to maintain the cooling – assuming you’re not sharing it.

But during that first couple of hours, it works pretty well. So it can help you cope with hot flashes, night sweats, and the frustrating problem of trying to fall asleep in hot weather.

It’s also worth noting that it feels soft under the body but doesn’t dramatically change the current feel of your mattress or topper. It’s not too heavy either and can be folded up neatly when you’re not using it.

Overall, the Gel’O Cool is a useful cooling pad that can help keep you comfortable in the first half of the night.

But if it’s essential that you have active cooling for the whole night, you might need one of the more advanced climate control systems.
