The standout feature of the Emma Premium Pillow is its ThermoSync technology, offering superior thermoregulation for a cooler, more comfortable sleep
The Emma Premium Pillow offers a unique experience thanks to its multi-layered, adjustable design.
The three layers include:
- Premium ThermoSync foam
- Supportive foam
- Comfortable soft foam
The pillow has a firm feel and high loft, making it an excellent choice for side sleepers.
However, the adaptability of the pillow allows it to suit all sleeping positions by simply removing or reordering the foam layers.
We recommend 2-3 layers for side sleepers, 2 layers for back sleepers, and 1 layer for stomach sleepers.
This feature comes with a minor drawback in that the layers and cover areย quite challenging to remove.
The Emma Premium pillow supported the neck and cushioned the head for a comfortable sleep that alleviated any pressure.ย
Another unique aspect is the thermoregulating layer and UltraDry cover, which ensure temperature regulation throughout the night - although it only shows a few degrees difference in our tests.
If you're a hot sleeper where those few degrees make a difference, then perhaps the Emma Premium pillow is worth the higher price tag.ย ๐ฅ
The Emma Premium pillow also includes a 30-night sleep trial and a 2-year guarantee for full peace of mind.ย

The Aeyla FOAMO Pillow is a state-of-the-art adjustable pillow.
It comes fully stuffed with easy-to-store spare fill.
It also includes a dual-case zip system to easily add or remove the fill material.
The fill is made from shredded, gel-infused memory foam for optimal support and temperature regulation.
The FOAMO pillow has a medium-firm feel, though this does depend on the stuffing level.
- The more fill, the higher the loft and the firmer the feel.
- The less fill, the lower the loft and the softer the feel.
The pillow cover is made from temperature-regulating bamboo, which further helps keep the pillow cool for a more comfortable sleep. ๐ฑ
You can wash the cover at 40โ but be sure to remove all fill material first.

What is a cool pillow?
A cool pillow is a great way to lower the temperature on a sizzlingly hot sleep. ๐ฅ

Studies show our core body temperature needs to drop 1 - 2 degrees to sleep comfortably throughout the night.
Pillows that stay cool aim to regulate body temperature and provide a calm and cooler sleep.
Excessively hot sleepers may also consider pairing a cooling mattress with their cool pillow for best results.
Do cooling pillows work?
A pillow with advanced cooling technology can offer a night of cooler sleep.
It may seem too good to be true, but these highly technical cooling pillows are made with the latest materials that help to prevent overheating.
But they donโt follow a one-size-fits-all approach. ๐ค
These ice-cold pillows encompass different elements that make them reasonably cooler than your standard pillow.
So, what are the best cooling pillow materials?
Types of cool pillows
You should consider the different types of cool pillows available. ๐งฝ๐ฑ๐
Some cold pillows use advanced materials that absorb body heat, whilst others offer natural ventilation.
Weโll take you through the pros and cons of each below! ๐
Gel pillows
Gel pillows are one of the most popular types of cooling pillows available.
Gel foam is designed specifically for those who feel the heat at night and can be found in many products, including gel mattresses.
Gel foam feels similar to memory foam, except it is made with tiny gel crystals inside the material. โจ

These crystals absorb body heat, which helps to regulate body temperature throughout the night.
A pillow that stays cold is often designed with a foam core insert made of gel or an outer cooling gel pad on the cover.
However, no science-backed studies prove that a gel memory foam pillow effectively combats hot sleep. ๐ค
Whilst many claim gel pillows have eradicated their night sweats, others assert these products have had little effect.
The Silentnight Wellbeing Cool Touch pillow has an outer gel cooling pad for a cool-to-the-touch sensation.
Memory foam pillows
Memory foam hasnโt got the best reputation for being cool.
Typically, memory foam is one of the warmest materials available. ๐ฅต
Just take a look at the temperature scale chart below:

Memory foam traps heat, unlike some other pillow materials.
This creates a build-up of warmth in the bed that can have you waking up shimmering with sweat.
So, why are they on this list? ๐ง
Memory foam has become increasingly advanced, particularly higher-quality memory foam fill designed with an open-cell structure.

Open-cell foam is much more breathable and can disperse heat better than cheaper foams. ๐งฝ
Some memory foam is also made with PCM, which stands for โphase changing materialsโ.
This highly scientific technology turns solid memory foam cells into liquid form, allowing excess heat to be absorbed more efficiently. ๐ง
Tempur is one of the first memory foam manufacturers to use PCM technology in their products.
The Temper Cloud CoolTouch pillow is one of our favourites, made with soft pressure-relieving memory foam.

Hollowfibre pillows
Hollowfibre pillows are one of the most common pillow types you can buy.
Most people have slept on a hollowfibre pillow in their lifetime.
These are one of the most affordable pillows, made from cost-efficient materials. ๐ฐ

Hollowfibre pillows are lightweight and made with breathable open fibres that are often hypoallergenic.
Air can easily be circulated through the open fibres, allowing cool air to flow through and hot air to disperse out of the pillow. ๐ฌ๏ธ
This ventilation system is even more effective when paired with a breathable outer pillow cover and pillowcases.
If youโre on a budget, a breathable pillow made with hollowfibre is an excellent option. ๐
The Kally Cooling pillow is budget-friendly but doesn't compromise on quality or coolness.

Natural fibre pillows
Natural fibre pillows are made from naturally-sourced materials such as wool, feather, cotton, or bamboo.
Natural fibre pillows work similarly to hollowfibre pillows but with even better benefits. ๐
Like hollowfibre pillows, the open fibres allow air to flow throughout the pillow.
Additionally, natural fibres such as wool act as a thermo-regulator that will regulate body temperature depending on if youโre hot or cold.
Naturally cool materials like wool, cotton and silk wick away moisture, making them ideal for those who suffer from night sweats.
However, whilst natural fibre pillows are one of the best options, they tend to be expensive.
But if you have no budgetary constraints, we encourage you to reap all the rewards from natural fibre pillows, such as a feather or wool pillow.
The Woolroom Deluxe Natural wool pillow is filled with soft wool and has a breathable cotton cover.
Latex pillows
Technically, latex also counts as a natural pillow, but their cooling techniques work a little differently.
Latex derives from tree sap, a sustainably sourced material that protects the environment. ๐

This material has a natural open-cell structure, which offers better breathability.
Latex pillows are manufactured with tiny pinholes throughout, designed to encourage airflow.
These pinholes push warm air out and draw fresh cold air in, creating a superb ventilation system. ๐ฌ๏ธ
Check out the video below to see how this works:
Latex is also highly durable, so your latex pillow can last five years or longer.

Who are cooling pillows most suitable for?
A cooling pillow can make an excellent option for anybody sensitive to heat.
However, theyโre a particularly good option for:
- Naturally hot sleepers
- Those suffering from menopausal symptoms
- People who suffer from night sweats
- Pregnant women
- Sleepers of all positions
If you fall into any of those categories, a cool pillow is a great way to tackle those hot flushes and provide an overall cooler sleep. โ๏ธ
Best cool pillow for your sleeping position
Unfortunately, itโs not as simple as choosing the best cool pillow on the market. ๐
Itโs essential to choose not only a pillow that is cool but also one that is suitable for your sleeping position.
So, what is the best cool pillow for your sleeping position? ๐
Best cooling pillow for side sleepers
Side sleepers need a deep and firm pillow. ๐งฑ
Side sleepers should opt for a cool pillow that is firm enough to support the head and shoulders and deep enough to encourage neutral alignment of the spine or neck.

The Simba Hybrid pillow is a great pillow for side sleepers.
This cool pillow has a firm feel with Nanocube foam to fill the space between the head and shoulders.

Best cool pillow for back sleepers
Back sleepers need a medium-feel and medium-height pillow. ๐งธ
Back sleepers require a cooling pillow that cushions the head and shoulders without sinking in too deeply or too little.
A medium support pillow will help keep the spine straight with the neck, preventing unwanted bending.

The Kally Cooling pillow is a good choice for back sleepers. โ๏ธ
The blown hollowfibre fillings and the cool foam core combine support and comfort for a pillow that feels just right.
The breathable materials counteract hot flushes whilst supporting the head and neck in a natural position. ๐ฅฐ

Best cool pillow for stomach sleepers
Stomach sleepers need a low loft and soft pillow. โ๏ธ
Stomach sleepers will get on great with a cool pillow that keeps the head as close to the mattress as possible.
The Tempur Cloud CoolTouch pillow has extra-soft shredded memory foam that will mould around the head and neck to keep the spine aligned.
BUY TEMPUR COMFORT CLOUD PILLOWยฃ 109

However, this pillow may feel slightly too high for some stomach sleepers. ๐จ
Stomach sleepers that suffer from night sweats and neck pain should consider sleeping without a pillow.
Ditching your pillow altogether might be the answer to more restorative sleep. โจ
What is the best way to keep cool at night?
You shouldnโt just rely on a cooling pillow to keep your hot flushes at bay during the night. ๐ค
There are lots of ways you can encourage a cooler sleep throughout the year.
So, what are they? ๐
Use a cooler duvet
Sleeping with a lower tog duvet can affect how hot you feel at night.
Take a look at the chart:

As you can see, tog ratings below 4 are much cooler and will prevent you from getting too toasty.
You could also consider duvets with cooling technology in the fibres.
The Simba duvet is designed with Stratos Active temperature regulation technology, Simba-Renew fibres that dissipate heat and a breathable cotton cover.
These space-inspired materials provide a much cooler sleep.โ๏ธ

Open the windows
Opening your windows at night will allow fresh air to flow and cool you down. ๐ฌ๏ธ

This works even better if you open more windows adjacent to the bedroom to create a cross breeze and encourage optimal airflow.
If itโs hot during the day, try to keep your curtains and blinds shut.
This will prevent the heat from building up inside your home during the day and can help cool down your room.
Shower before bed
After a swelteringly hot day, a shower is a great way to cool down just before bed. ๐ฟ

It will also help those with sensitive skin to prevent dirt and bacteria from building up in the bed, which can cause skin reactions.
You may think that having a cold shower is the best way to stay cool, but research indicates that a warm bath is a better solution for a good night's sleep. ๐ด
This will activate your brain into thinking it's time for bed, and encourage your body temperature to lower up to 2 degrees.
Why not also consider a bath pillow to wind down at night?
Use natural sheets and pillowcases
Sheets made from cotton, silk, or even bamboo are an excellent choice for those looking to lower the temperature while you sleep. ๐ก๏ธ
You could try silk pillowcases for an extra luxurious feel.
The natural properties are great for sweaty sleepers as they wick away moisture during the night.
They're also highly breathable and much kinder to sensitive skin. ๐ฆ
Check out our favourite natural sheets for a cooler sleep:
Can you wash a cool pillow?
If you suffer from night sweats, you might need a fully washable pillow to ensure your pillow stays clean. ๐งผ
This will help increase the lifespan of your cool pillow and keep it fresher for longer.
Some cool pillows, such as the TempurCloud CoolTouch pillow, come with a washable cover.
BUY TEMPUR COMFORT CLOUD PILLOWยฃ 109
But some cooling pillows are fully machine-washable.
You should check your pillow tag or the manufacturerโs website to see if your cold pillow is washable. ๐ท๏ธ
Here you will also find details of the recommended setting and whether the pillow can be tumble-dried.

Other ways to keep your pillow cold
It's not easy finding a pillow that stays cold all night long.
Bedding accessories like cooling pillow cases are highly breathable and can help your head stay cool during sleep.
You can also get more advanced cooling accessories like a cooling pillow pad.

Cooling pads have been a popular way to chill out at bedtime, particularly for menopausal women.
You can put the cooling pad into the fridge for ten minutes and then insert it into your pillowcase, where you should feel noticeably cooler.
You can also pop the cooling pad behind your back when sitting down or even rest your feet on it for those who feel the heat day and night. ๐๐
There are many cool pillow mats for pillows and mattresses available on Amazon.
Take a look below:
How much do cool pillows cost?
The price of a cool pillow depends on the quality of the pillow youโre buying. ๐งต

High-quality pillows are going to be more costly but potentially more effective for keeping you cool.
On the other hand, cheaper solutions such as a cooling pad can provide a refreshing sleep without breaking the bank.
Typically, cool pillows begin at around ยฃ15 for a more budget-friendly product.
Premium cool pillows will cost over ยฃ50 depending on the quality and materials.
Cool pillow discount codes
