It’s not easy to sleep when you can feel your sweat tickling your skin as it rolls off you in the fabric sauna your bedroom has morphed into.
Keeping your bedroom at a cooler temperature is often overlooked as a key ingredient for good sleep.
The good news is that whether you’re kept awake by hot flashes, warm weather or just sleep hot, there are effective ways to lower your temperature in bed.
In this review, I’ll be looking at the 2 main approaches: cooling mattress pads and bed fans. Depending on your budget and the level of cooling you require, they range from specialty mattress pads to complex bed cooling systems.
Hopefully, you’ll find something here which helps make your bedroom the cool sanctuary of rest it should be.
1. BedJet 3 Climate Comfort
Best bed cooling system
The Bedjet 3 is my top pick of the bed cooling systems with its sleek design, great performance, and effectiveness across a range of desired temperatures.
At the moment, there isn’t another similar system on the market which can so reliably keep you cool throughout the entire night.
Made so that it can be fitted to any sized bed and mattress, you can either have cold 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.
In the winter, the BedJet can be used as a heating system and is just as effective. And if you and your partner have different temperature preferences, you can get dual fans to choose your own temperatures.
The motor runs smoothly and quietly, so it won’t disturb you in the night. It comes with a color screen remote control which you can use to change all the settings, such as the temperature, fan speed, auto-off timers. You can also program it to change temperatures automatically in the night.
The main downside is that it’s quite an expensive piece of kit, especially the version with dual zones. So if you just need a little extra cooling at night, cooler bedding might do the trick.
But if you need something which will reliably keep you cool and comfortable at night, you won’t find a more effective way to keep the heat at bay than the BedJet 3.
My partner and I have been using a BedJet for the last two and a half years, and have been very happy with how well it works.
2. SlumberCloud Nacreous Cooling Mattress Pad
Best cooling mattress pad
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.
That said, it’s important to remember that it can’t change the actual room temperature. What it will do, however, is stop you feeling like you’re lying on top of a radiator.
For me, it’s the best cooling solution in the form of bedding. The BedJet will 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 the unpleasant hot feeling that can build up underneath you during the night.
3. ChiliPad Cube
Mattress pad water cooling system
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. And that’s an advantage compared to most gel pads and fabric toppers, which tend to work for a couple of hours before your body heat overwhelms them.
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 55° – 110° Fahrenheit (12.8-43.3 Celsius). And with the option of dual remote controlled units for larger bed sizes, you and a partner can have the exact temperature you need.
One possible issue that some people might face is that it’s quite complicated to set up initially. It’s also worth bearing in mind that you don’t just plug it in and forget about it, as some maintenance is required – though it’s not particularly difficult or time-consuming.
Overall, the ChiliPad is a good cooling device, and one to consider if you need a way to keep the rising heat at bay throughout the whole night.
4. Leisure Town Cooling Mattress Pad
A low-cost breathable mattress pad
The Leisure Town cooling mattress pad tackles the issue of overheating in bed from two angles, and does a pretty good job on the whole.
Firstly, the manufacturer claims it uses ‘new HNN cooling technology’. What that actually means is a bit of a mystery though, and I still haven’t found a formal definition that isn’t simply repeating the product description.
They say the HNN technology increases airflow in the mattress pad, which makes it more breathable and reduces heat build-up. And in my experience, the pad does sleep less hot than most others.
Perhaps it’s helped by the fact that the cover is a 300 thread count cotton, which is also a good fabric choice to place under you in hotter weather. The fill itself is described as ‘state of the art snow down alternative’. It’s basically fiber-fill, but still breathable while being comfortable to sleep on.
It’s worth bearing in mind that although it does have some fill to add comfortable padding, this is a pad and not a topper; the thickness isn’t as substantial as thicker toppers.
Overall, this is a pleasantly breathable mattress pad for those stifling summer nights, and at a low price. It’s also conveniently machine-washable, making it a good all-around choice.
5. Sleep Better Iso-Cool Mattress Topper
3 inch 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.
An unavoidable fact, 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.
However, as the night progresses, it becomes less effective because your body heat and memory foam below will slowly overwhelm the outlast cover. So if you tend to wake in the night in a pool of sweat, you might find it struggles to keep up.
But if you only need a little extra cooling, 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 comfortable mattress topper which adds soft padding to your mattress and helps regulate your temperature. But if you need more intensive cooling, memory foam isn’t the way to go about it.
