What Is a Cooling Mattress?
A cooling mattress is designed to help manage heat and moisture while you sleep. Mattress construction, materials, breathability and airflow can all influence how warm or cool a mattress feels.
There is no single material that guarantees a cool night's sleep. Your bedroom temperature, bedding, sleepwear and personal temperature preferences can also affect how warm you feel.
Breathable
Materials and construction that allow air to circulate can help reduce heat build-up.
Airflow
Spring-based constructions can allow air to move more freely through the mattress.
Moisture Management
Breathable covers and moisture-managing materials can help create a more comfortable sleep surface.
Comfort
Cooling features should still provide the support and pressure relief you need.
Who Should Choose a Cooling Mattress?
A cooling mattress may be worth considering if you regularly feel too warm during the night or prefer a cooler sleeping surface.
HOT SLEEPERS
Reduce Heat Build-Up
Look for breathable materials and constructions designed to encourage airflow.
WARM BEDROOMS
Prioritise Breathability
A breathable mattress can complement a well-ventilated bedroom and lightweight bedding.
COUPLES
Consider Both Sleepers
If one person sleeps warmer than the other, mattress construction and breathable bedding can help create a more comfortable compromise.
Menopause, Hot Flushes & Night Sweats
Hormonal changes during menopause and perimenopause can cause hot flushes and night sweats, which may make it harder to stay comfortable and get a good night's sleep. While a mattress cannot prevent hot flushes, choosing breathable materials and a mattress designed to encourage airflow may help create a more comfortable sleeping environment.
BREATHABILITY
Encourage Airflow
Look for mattress constructions that allow air to circulate, such as pocket sprung or hybrid designs.
MOISTURE MANAGEMENT
Choose Breathable Bedding
A cooling pillow, lightweight duvet and moisture-managing sheets can help make the sleep environment more comfortable.
COMFORT
Don't Sacrifice Support
A cooler mattress still needs to provide the support and pressure relief that suit your preferred sleeping position.
If hot flushes or night sweats are regularly disturbing your sleep, it may also be worth speaking to a healthcare professional for personalised advice.
Which Mattress Materials Sleep Coolest?
The materials used in a mattress can affect airflow, heat retention and how warm the surface feels. Consider the complete construction rather than focusing on one material.
Pocket Springs
The open space around individual springs can encourage airflow through the mattress.
Latex
Latex can offer a responsive feel and, depending on construction, good breathability.
Memory Foam
Traditional dense memory foam can retain more heat, but some designs incorporate ventilation and cooling features.
Are Hybrid Mattresses Good for Hot Sleepers?
Hybrid mattresses combine springs with comfort layers such as foam or latex. The spring core can allow more air movement than a dense all-foam construction, while the comfort layers provide cushioning.
The open spring system can help air circulate within the mattress.
Springs can provide a supportive and responsive base.
Foam or latex comfort layers can provide cushioning without relying on a completely foam-based construction.
Can Memory Foam Be Cooling?
Yes. Memory foam mattresses can incorporate cooling technologies and breathable materials. However, traditional dense memory foam can retain heat because it conforms closely to the body.
Look For
- Breathable mattress covers
- Ventilated or open-cell foam
- Cooling or temperature-regulating materials
- Mattress designs that encourage airflow
Keep In Mind
- Dense foam can still feel warmer
- Close body contouring can reduce airflow around the body
- Cooling features vary between models
- Your bedding can have a major effect on temperature
Does the Mattress Cover Matter?
Yes. The material and construction of the mattress cover can affect how the surface feels and how effectively heat and moisture are managed.
Look for covers designed to allow air to move and help manage moisture.
Some mattress covers incorporate fibres or treatments designed to create a cooler-feeling surface.
A removable and washable cover can make it easier to keep the sleep surface fresh.
Does Mattress Depth Affect Temperature?
Mattress depth alone does not determine whether a mattress sleeps hot or cool. The materials and construction inside the mattress are more important considerations.
Thicker layers of dense foam may retain more heat depending on their construction.
A ventilated spring system can encourage airflow through the mattress.
Consider how all the layers work together rather than choosing based on thickness alone.
What Bedding Should I Use With a Cooling Mattress?
Your duvet, sheets, mattress protector and sleepwear can all influence how warm you feel. Pairing a cooling mattress with breathable bedding can help create a cooler overall sleep environment.
Choose a tog rating appropriate for the season and your personal comfort.
Natural or breathable fabrics can help create a more comfortable sleep surface.
Choose a breathable protector so it doesn't unnecessarily trap heat between you and the mattress.
Does the Bed Base Affect Cooling?
The base underneath your mattress can influence airflow and ventilation. A well-ventilated base can complement a breathable mattress construction.
Gaps between suitable slats can allow air to circulate underneath the mattress.
A divan can provide excellent mattress support, but check the mattress and base specifications for ventilation requirements.
Some cooling mattresses are compatible with adjustable bases. Always check compatibility before purchasing.
Cooling Mattress Buying Checklist
Before choosing a cooling mattress, check these key features.
Look for materials and construction that encourage airflow.
Check whether the cover is breathable and designed to manage moisture.
Consider springs, foam, latex and the way the layers are arranged.
Cooling should not come at the expense of the support and comfort you need.
Consider your duvet, sheets and mattress protector as part of the overall sleep system.
If available, a sleep trial can give you time to assess how comfortable the mattress feels in your own bedroom.
Frequently Asked Questions
What is a cooling mattress?
A cooling mattress is designed to help manage heat and moisture while you sleep. Materials, construction, airflow and the mattress cover can all influence how warm or cool it feels.
What is the best mattress for hot sleepers?
There is no single best mattress for every hot sleeper. Look for breathable construction, good airflow and materials that suit your comfort preferences. Hybrid and spring-based mattresses can be worth considering if airflow is a priority.
Are memory foam mattresses hot?
Traditional dense memory foam can retain heat because it closely contours to the body. However, some modern memory foam mattresses use ventilation, open-cell structures or cooling materials to improve temperature management.
Are hybrid mattresses cooler than memory foam?
Hybrid mattresses can allow more airflow through their spring core, which may help with temperature regulation. However, the overall construction and comfort layers also matter.
Does a mattress protector make a mattress hotter?
It can, depending on its materials and construction. If you sleep hot, look for a breathable mattress protector that does not unnecessarily trap heat.
Does mattress firmness affect how hot you sleep?
Firmness itself is not the main factor. The materials, construction and degree of body contouring can have a greater influence on heat retention and airflow.
Are pocket sprung mattresses good for hot sleepers?
Pocket sprung mattresses can be a good option for people who prioritise airflow because the spring system can allow air to circulate through the mattress.
Can latex mattresses sleep cool?
Latex can offer a breathable and responsive feel, although the overall mattress construction, cover and other layers also affect temperature regulation.
What bedding is best for hot sleepers?
Lightweight, breathable bedding can help. Consider your duvet tog rating, sheets, mattress protector and sleepwear alongside the mattress itself.
What is the best mattress for menopause and hot flushes?
There is no single best mattress for everyone experiencing menopause or hot flushes. Look for a breathable mattress with good airflow and a cover designed to help manage moisture.
