What is a mattress topper?

A mattress topper is a soft cushioning layer that enhances the feeling of your mattress. ☁️

It attaches to the top of your mattress and promotes a more comfortable sleep for those lacking support.

A cooling mattress topper can give a softer feel to a mattress that feels too firm, which helps to prevent back pain and sore joints.

Do mattress toppers keep you cool?

The primary function of a mattress topper isn’t to keep you cool.

Mattress topper making bed softer
Mattress toppers add extra softness to your sleep.

Whilst a mattress topper can have cooling properties; the primary function is to promote comfort and relieve pressure.

Typically, a mattress topper is made from memory foam, wool, or latex, which has mixed results in cooling you down at night.

Yet, some mattress toppers are cooler than others and made with heat-absorbing materials. ♨️

Consider a cooler mattress

A cooling mattress topper isn’t a miracle worker.

If you have a warm mattress, then a cooling mattress topper won’t do much to keep you cool.

Memory foam mattresses create a warmer sleep and aren’t the best choice for hot sleepers. 🥵

It might be time to upgrade to a cooling mattress instead.

How do cooling mattress toppers work?

Cooling mattress toppers work by having temperature control properties in the material.

This means absorbing body heat or pushing away moisture from the mattress whilst you sleep.

However, how a cooling mattress topper functions depend on the material.

So, what are they? 👇

Gel mattress toppers

Gel mattress toppers are one of the most popular cooling mattress topper options.

Whilst they feel similar to memory foam, moulding around the body to reduce pressure, they’re much cooler.

This is because gel mattress toppers contain little gel beads with phase-changing materials that draw heat away from the body. ♨️

Woman on gel mattress topper
Gel mattress toppers are one of the coolest options.

Gel mattress toppers are typically firmer than memory foam, meaning they don’t “hug” around the body as much. 🤗

This is great for those who want to reduce pressure on the joints without feeling suffocated.

Whilst we think gel mattress toppers are great, it’s important to remember that there are no scientific-backed studies to support their cooling effects.

Instead, gel mattress toppers are popular because of the positive customer response to this material and its cooling capabilities.

Latex mattress toppers

Many people make the mistake of assuming latex is warm like foam.

Yet, latex is highly breathable.

Latex comes from sap in rubber trees that can be harvested without harming the tree. 🌴

Latex being harvested
Latex is a naturally sourced material.

Unlike foam, latex has an open-cell structure, allowing the material to breathe.

Latex toppers are also manufactured with tiny pinholes throughout the material, which heat can pass through. 🌬️

Latex mattress toppers feel similar to foam, contouring around the body without creating a warm surface.

Latex is also one of the most durable mattress topper materials, meaning your cooling mattress topper may last as long as 20 years.

Latex mattress benefits
Latex is hypoallergenic, sustainable, and cool.

Shredded latex, such as the Evergreenweb latex topper, is even more breathable because of its shredded structure, which encourages greater airflow.


Memory foam mattress toppers

You might be surprised to find memory foam on this list. 🤔

Typically, memory foam is a material that traps heat and encourages a warmer sleep.

However, as memory foam products become more advanced, there are some exceptions.

Memory foam mattress topper
Memory foam mattress toppers have superb contouring abilities.

Some memory foam toppers are infused with a cooling agent that counteracts the warm properties of memory foam.

This could be graphite, gel, or another type of cooling material.

For example, the Panda mattress topper is primarily made of memory foam but is infused with cooling gel microbeads that help to dissipate heat.

This cooling mattress topper also includes a bamboo cover, a naturally breathable material that wicks away moisture. 💦


Hollowfibre toppers

Hollowfibre is also a much cooler mattress topper when compared with a dense material like memory foam. ☁️

Hollowfibre is highly breathable, with gaps between the lightweight fibres that promote air circulation.

Hollowfibre toppers encourage airflow.

Often, hollowfibre mattress toppers can be machine-washed.

This makes them an excellent choice for those that sweat during the night.

The Silentnight Airmax Topper is one of our favourite cool hollowfibre options. ✅


What’s the difference between a mattress pad and a mattress topper?

A cooling mattress pad and cooling mattress topper are two different products.

A cooling mattress pad is a thin layer that goes on top of your mattress.

Unlike a mattress topper, a cooling mattress pad’s primary function is to reduce the temperature of your sleep. 🌡️

mattress pad vs mattress topper
A mattress pad and mattress topper have different primary functions.

If you are an excessively hot sleeper suffering from menopause or night sweats, we recommend using a cooling mattress pad.

Though they don’t enhance the feeling of the mattress, they can make your sleep significantly cooler.

Cooling mattress pads contain a gel that absorbs heat and pushes it away from the body.

Some can also be refrigerated before use for a comfy and cool sleep. 🧊

Take a look at our favourite cooling mattress pad below!

How else can you stay cool at night?

You shouldn’t just rely on bed products to help you sleep cool.

In fact, there are many ways you can lower the temperature of your sleep.

Our tips below can ensure a better night’s sleep with a cooler bedtime routine. 👇

Take a lukewarm shower or bath before bed

Most people might believe a cold shower before bed can help keep you cool.

But research suggests that a warm or hot bath is a better solution.

A warm bath relaxes the muscles and can even lower your blood pressure.

A warm bath before bed can keep you cool.

Hot water also helps activate your body’s core temperature and helps it lower just in time for sleep. 😴

As our body temperature naturally lowers during sleep, a bath can help trigger your brain into understanding it’s time for bed, which can help you fall asleep faster.

A bath pillow is a great way to help you wind down in the bath before bed.

Sleep with a lighter tog duvet

The duvet you sleep with can make a massive difference to a good night’s sleep.

Most standard duvets come in a 10.5 tog for year-round suitability.

Tog ratings and temperature
Lower tog ratings are much cooler during sleep.

But you can get duvet tog ratings as low as 1. 😲

You should also consider the duvet materials.

The Panda Cloud duvet is made with temperature-regulating bamboo fibres for a cooler sleep.


Choose a cooler pillow

If you’re someone that frequently flips your pillow to the cold side, you’ll be please to know that some pillows stay cool all night. 😅

Like mattress toppers, many pillows are made with cooling technology that can absorb heat and keep you cool during the night.

Our cool pillow review can tell you everything you need to know about the best cool pillows in the UK.

Cool pillow
Cool pillows draw in cool air and release hot air.

If you already love your pillow, then you might consider a cool pillow pad instead.

The Chillow pillow pad is filled with water and can be popped into the fridge before bed for extra coolness.

It’s been a popular choice to combat hot flushes and night sweats. 🥵


Use natural fibre sheets

Natural sheets are the superior option when it comes to staying cool.

Unlike synthetic fitted sheets, natural sheets such as cotton, silk, and bamboo have advanced cooling abilities.

They are highly breathable and able to wick away moisture during the night. 🌬️

moisture-wicking fabric
Natural fibre sheets push away excess moisture during the night.

They can also absorb extra heat and cool you down on a hot night.

Take a look at our favourite natural sheets below:

Are cooling mattress toppers washable?

Most cooling mattress toppers aren’t safe for the washing machine.

This is because they are made with materials that may become damaged when in contact with hot water.

However, some toppers made with synthetic fibres like the Silentnight Airmax mattress topper are machine-washable. ✔️


Other mattress toppers may also come with a washable cover.

Washing a mattress topper cover
Some mattress toppers have washable covers.

The mattress cover can be popped into the wash with your regular bedding and left to air-dry before replacing it onto your topper.

We highly recommend using a mattress protector alongside your mattress topper.

A waterproof mattress protector will protect your topper and mattress from stains and bacteria build-up.

A mattress protector made with natural fibres will help to encourage airflow throughout the mattress. 🌱

Take a look at our recommendations below:

Cool mattress topper sizes

Cooling mattress toppers come in standard UK mattress sizes.

  • Single mattress topper: 90 x 190 cm (3' x 6'3")

Cool mattress topper prices

A good quality cooling mattress topper typically starts from around £100 - £150. 💰

Mattress toppers made with high-quality materials, such as the Simba mattress topper, are much more expensive.

-35% SIMBA TOPPER£ 148.85

man sitting on coins
Cooling mattress toppers are reasonably priced.

Depending on your size, these premium toppers like this can set you back around £200 - £1000.

But how much should you spend on a mattress topper?

Consider your budget, how often the topper will be used what kind of warranty it has.

A topper that is more expensive but has a longer guarantee may be a worthwhile investment as it won’t need to be replaced as often. 🤞

Should I buy a cool mattress topper?

A cool mattress topper is an excellent buy for those looking to level up their sleep without overheating.

We think they’re a great buy for those who feel warm at night and need extra comfort for their mattress. ✅

However, a cooling mattress pad is a better option for excessively hot sleepers looking for a significant improvement in how cool they feel during sleep.

If you have a memory foam mattress, consider changing it for a cooler alternative.

Here’s a reminder of our favourite cool mattress toppers:

Frequently asked questions:

  • What are the best cool mattress toppers for hot flashes?

    We recommend a cooling mattress pad instead of a cool mattress topper if you suffer from regular hot flashes.

    A cooling mattress pad is more successful at absorbing heat and keeping you cool. 

    Amazon has a great selection of cooling mattress pads. 

  • Where to buy a cooling mattress topper

    You can buy a cooling mattress topper from various online retailers.

    This includes:

    • Bensons for Beds
    • Dreams
    • John Lewis
    • Argos
    • Dunelm

    Amazon also has an excellent range of cooling mattress toppers with Prime Day deals and discounts throughout the year.

  • Do cooling mattress toppers really work?

    Cooling mattress toppers can be a great option for those who need a combination of comfort and coolness for their sleep.

    We recommend them to side sleepers as the added top layer of comfort to the mattress can relieve pressure on the shoulder and hip in the side sleeping position.

    Mattress toppers with cooling technology will promote a cooler sleep by absorbing excess heat and encouraging air to circulate throughout the mattress.

    However, a cooling mattress pad might be more effective if you feel overly hot at night.
