The Best Cooling Mattress Pads & Bed Fans For Hot Nights

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 tend to sleep hot, there are effective ways to lower your temperature in bed.

In this review, I’ll be looking at the two 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

A fan-based bed cooling system with cool air, dual zones and superb controls.

The Bedjet 3 is my top pick of the bed cooling systems. It has a sleek design and fantastic controls, with effective, fast, and targeted cooling for as long as you need it.

Made so that it can be fitted to any size bed and mattress, 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 (as well as two phone Apps) so you and your partner can control the temperature on your side.

It comes with a color screen remote control which you can use to change all the settings, such as the temperature, fan speed, and auto-off timers. You can also program it to change temperatures automatically in the night.

The BedJet 3 also functions as a heating system in colder weather and I’ve found it to be more effective and energy efficient than heated bedding. It also means you can have cooling on one side 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 nine inches. If you don’t have that, you’ll need to keep it next to the bed and remember it’s there when you get up in the night.

Another potential issue is that the fan makes some noise, which is fine if you like fan sounds; it’s quite a soft hum on low-mid speed settings and pleasant to have in the background. But if you need silence to sleep, the noise on the highest speed setting might be too much.

Overall, if you need an active cooling system that will reliably keep you cool and comfortable at night, the BedJet 3 is definitely a good option, especially if you like the feel of cool air.

Warranty / trial period: It comes with a 60 day trial period so you can test how well it works and get your money back if it’s not right for you. They have an extended two year manufacturer’s warranty and will fix or replace any parts if needed.

Price: The BedJet 3 costs between $400 and $500 for a single unit, depending on seasonal sales. If you want two units, you’re looking at around $1000. I use just the single unit, and I recommend doing that to save some money unless you and a partner have very different temperature preferences.

2. Chilisleep Ooler Sleep System

The Ooler is the latest cooling system from the company Chilisleep, and tackles the concept of bed cooling in a unique way. Along with the BedJet 3, it’s one of the few bed cooling products which can handle more serious heat problems.

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 comfortably 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 most important point is that it can keep you cool all night long. 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. And the cooling will be evenly spread across your entire bed and body, which feels great in warm weather.

The temperature range means you can use it for cooling or heating, with a range of 55° – 115° Fahrenheit (12.8° – 46.1° Celsius). And with the option of dual zones with separate remote controls for larger bed sizes, you and a partner can have the exact temperature you need on your side of the bed.

Like the BedJet 3, the main downside is that you need space for the base unit under or next to your bed. It also emits a gentle humming sound, which might disturb those who need absolute silence.

Overall, the Ooler is a very effective cooling system for your bed, and one to consider if you need a way to keep the rising heat at bay throughout the whole night.

Warranty / trial period: They offer a 30 day money-back trial period and a two year limited warranty, offering to fix and/or replace any parts if deemed defects of the device.

Price: The price depends on two factors: whether you need one or two units, and your bed size. For example, a single unit for a queen costs around $800, while two units for a king will cost around $1700.

Again, I recommend only getting two units if you share your bed and both of you would like control over the temperature. Otherwise, you can save a considerable amount of money by just having the cooling pad on one side.

3. Slumber Cloud Performance Mattress Pad

A mattress pad that helps dissipate body heat.

The Performance cooling mattress pad by Slumber Cloud is designed 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. The pad uses 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, describes 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.

The Performance is the latest of four cooling mattress pads made by Slumber Cloud. The main improvement in this one is that the outlast material is now paired with Tencel Lyocell for better moisture wicking in addition to the heat absorption.

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.

The main downside is that it’s not an active cooling system and it can’t change the actual room temperature. What it will do, however, is stop you from feeling like you’re lying on top of a radiator.

Another point to keep in mind is that it’s not as thick as many toppers as it’s only a pad, so it won’t provide a significant amount of extra softness. Perhaps that’s a good thing though if you’re already happy with the level of support your bed currently provides.

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.

Warranty / trial period: Slumber Cloud offer a 60 day trial period, so you can test it out and send it back if you don’t like it. They have a 180 day manufacturer’s defects warranty too, which allows plenty of time to discover any defects.

Price: It comes in seven sizes, and the price varies accordingly. It’s currently $169 for the smallest size – the twin, and $259 for the largest size – the split king.

They also have a wide range of other cooling bedding products. I’ve used the pillowcases and comforter, and loved the comforter in particular in the summer.

4. Molecule Triple Zone Pro Mattress Topper

A breathable mattress topper that also provides comfort and pressure relief.

Molecule designs both mattresses and mattress toppers in a way that makes them more breathable than traditional memory foam mattresses. They say their cooling toppers are air engineered using processes they created themselves to ‘maximize airflow and facilitate cooling’.

When you look at the materials of the Triple Zone Pro mattress topper, you might think it’s unlikely to feel particularly cool: there are two layers of memory foam and a polyester cover.

However, I’ve found that the heat builds up much more slowly than standard memory foam, especially lower-quality memory foam toppers.

They say their open cell memory foam has five times more airflow than standard memory foam, but with the buoyancy of latex. And when you take a closer look at the inner material, I found it does appear to have considerably more space for airflow, yet it remains strong enough to hold even my relatively heavy body.

What I really like about this one is that it feels like a plush, comfortable and supportive mattress topper when you lie on it. It’s the kind of topper I’d be happy to have just for the level of comfort it provides and the relief from pressure points across the whole body.

The main downside is that no matter how diligently the material is engineered, it won’t cool you as effectively as an active bed cooling approach like the BedJet 3 or Ooler. On the other hand, it’s considerably cheaper and serves a dual purpose.

So my feeling is that this could be a good choice if your main desire is for a comfortable and supportive memory foam mattress topper that doesn’t sleep too hot for once. But it might not be right for you if maximizing the cooling is your only need because you already have a comfortable enough bed.

Warranty / trial period: Molecule has a 30 day return window for toppers, and a five year limited warranty for materials and craftsmanship defects.

Price: The price will depend on your bed size, with six sizes to choose from. For example, the twin costs around $200, while the cal king is around $300.

5. Leisure Town Cooling Mattress Pad

A low-cost, breathable mattress pad.

Finally, we come to a budget option that won’t break the bank and should feel more breathable than some of the denser mattress toppers and pads out there.

The Leisure Town cooling mattress pad tackles the issue of overheating in bed with a breathable structure and soft cotton cover, and it does a reasonable job on the whole. There’s no tech to plug in, and there’s no memory foam to be worried about.

To keep it feeling cooler, the manufacturer says it’s made using ‘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.

The manufacturer states that 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 feel cooler under the body than many dense memory foam and thick polyester toppers I’ve tried.

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 warmer weather. The fill itself is described as ‘state of the art snow down alternative’. It’s basically fiberfill, 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, it’s more of a pad than a topper; the thickness just isn’t as substantial as more heavyweight toppers. However, the lack of extra padding does contribute to it being conveniently machine washable.

Overall, this is a reasonable option for warmer summer nights that aren’t too hot. Just be aware that it has limitations: it might add some extra breathability and comfort to your bed, but it won’t provide active cooling.

Warranty / trial period: As it’s sold on Amazon, you’ll get the standard protection as the manufacturer does state they offer a satisfaction service. It’s a bit of a vague statement, but I believe they’ll offer your money back if you’re not happy rather than risk a negative review by refusing to.

Price: Compared to the high price of specialist bed cooling products, it might suit those on a budget as all eight sizes from twin to cal king cost under $100 on Amazon, which is at the lower end of the price spectrum for mattress toppers and pads.
