If you regularly wake up at 3am having thrown off the duvet and flipped the pillow approximately four times, this one is for you. Sleeping hot is one of the most common, and most underestimated, reasons for poor sleep quality. And the frustrating thing is that for a lot of people, the culprit isn’t the temperature in the room. It’s the mattress.
Most mattresses trap body heat to some degree.
Some materials do it significantly more than others. And once you understand which constructions and technologies genuinely help regulate temperature overnight, the whole problem becomes a lot more solvable.
Here’s everything you need to know, including the materials that make the biggest difference, the science behind why you sleep hot in the first place, and our picks from the Land of Beds range for warm sleepers at every budget.
“Body temperature regulation is directly linked to sleep quality. Core body temperature naturally drops as we fall asleep and continues to decrease through the night. This cooling process is essential for entering and maintaining deep, restorative sleep. A mattress that traps heat and prevents that natural drop can significantly disrupt sleep architecture, even if the sleeper does not fully wake. For hot sleepers, choosing the right mattress material is not a luxury. It is a meaningful health decision.”

Why some people sleep hotter than others
Before we get into mattresses, it’s worth understanding why the problem exists at all.
Sleeping hot isn’t just about room temperature, although that matters too. Your body generates and releases heat throughout the night as part of its natural thermoregulation process, and how well your sleep environment supports that process determines how warm you feel.
Some people naturally run at a higher core temperature, some produce more heat during sleep, and some are simply more sensitive to temperature disruption. Hormonal changes (including those related to the menopause), certain medications, and conditions like hyperthyroidism can all make sleeping hot more pronounced.
The good news is that regardless of the underlying cause, the right mattress can make a significant difference, by drawing heat away from the body, encouraging airflow beneath the sleeping surface, and avoiding materials that trap heat close to the skin.
Why your mattress might be making it worse
This is the part most people don’t realise. Standard memory foam, the close-contouring, body-hugging material that has dominated the mattress market for the last two decades, works by responding to body heat. That’s what makes it so good at pressure relief: it softens as your body warms it, moulding precisely to your shape. But the same mechanism that makes it contour so well also means it retains heat. The foam sits close to your skin, the heat builds up between you and the surface, and by 2am you’re too warm to sleep properly.
The solution isn’t to avoid pressure relief entirely, it’s to find materials and constructions that deliver pressure relief without the heat retention. That’s exactly what the best cooling mattresses are designed to do.
The temperature drop that matters
The Sleepeezee Dual Seasons Deluxe uses a pocket spring unit that is up to 28% cooler than traditional foams, and its cooling fibres have been shown to keep body temperatures 1.3% lower than a standard tick. This contributes to the 1 to 2 percent reduction needed to reach the optimum body temperature for deep, restful sleep. That is not marketing language. It is the result of extensive testing by Sleepeezee scientists.
The materials that genuinely help
Not all cooling technology is equal. Here’s what actually works and why.
Latex
The most naturally breathable mattress material available. Latex has an open cell structure that encourages airflow throughout the mattress, keeping the sleeping surface noticeably cooler than most foam alternatives. Unlike memory foam, it does not respond to body heat. It responds to pressure, which means it does not trap warmth in the same way. For hot sleepers, latex is often the first material we recommend.
Gel foam
Gel infused memory foam addresses the heat problem directly. Cooling gel is added into the foam or the cover, and the open cell structure helps draw heat away from the body rather than retaining it. You still get the pressure relieving contouring of memory foam, but with noticeably better temperature regulation. A strong option if you want foam comfort without the warmth.
Pocket springs
Pocket sprung mattresses have a natural advantage when it comes to airflow. The open structure of the spring unit allows air to circulate beneath the comfort layers, helping heat dissipate more effectively. A quality pocket spring unit can be significantly cooler than dense foam constructions, particularly when paired with breathable fillings.
British wool
Wool is one of the most effective natural temperature regulators available. It wicks moisture away from the body, allows airflow to circulate through its fibres, and helps maintain a balanced sleeping climate in both warm and cool conditions. This is why it is widely used in premium mattresses designed for year round comfort.
Natural fibres
Materials such as cotton, silk, and cashmere are commonly used in higher quality mattresses to improve breathability and moisture control. These fibres allow air to move more freely through the mattress and help regulate temperature without relying on synthetic cooling technologies. They are particularly beneficial for hot sleepers who prefer a more natural sleep environment.
Breathable covers
The fabric that sits closest to your skin has more impact than most people expect. Cool touch covers and moisture wicking fabrics can reduce the perceived surface temperature immediately, before the deeper layers of the mattress come into play. A breathable cover is often the first line of defence for managing heat during the night.

Pillowtop comfort with cooling fabric and breathable construction for a fresher sleep surface
Spotlight pick
Sleepeezee Dual Seasons Deluxe
The year round temperature solution. Cool in summer, warm in winter without compromise.
Most cooling mattresses are designed for one job: keeping you cool. The Dual Seasons Deluxe takes a more considered approach. It is designed for year round comfort, with a dedicated cooling sleep surface on one side and a warmer, more insulating surface on the other. Turn it seasonally and the mattress adapts to the time of year rather than working against it.
The cooling performance is well supported by the materials used. The pocket spring unit is designed to allow airflow through the mattress, while the cooling fibres in the summer side cover help reduce body temperature during sleep. This contributes to the small but important temperature drop needed to reach deeper, more restorative sleep.
The Seasonal Turn Technology uses layers of Platinum Grade British wool on each side. This is a naturally breathable and moisture wicking material that helps regulate temperature throughout the night, keeping the sleep environment balanced in both warmer and cooler conditions.
Springs
1015 individually wrapped pocket springs
Cooling features
Seasonal Turn design, breathable fibres, British wool layers
Tension
Medium, suitable for a range of sleeping positions
Why this is our spotlight pick
Many cooling mattresses focus on a single condition. The Dual Seasons Deluxe is designed to work across the full year. For hot sleepers who also feel the cold in winter, or for couples with different temperature preferences, this is one of the most practical and well considered solutions available.

Silentnight Lunix Pillowtop
A cooler surface feel with added comfort through a cushioned pillowtop layer.
Some mattresses feel warm not because of the core construction, but because of the surface you are sleeping on. The Silentnight Lunix Pillowtop focuses on that first point of contact, using a breathable cover and pillowtop layer to create a fresher, more comfortable sleep surface.
The pillowtop adds a layer of cushioning that sits above the main mattress, helping to reduce pressure while maintaining airflow around the body. Combined with a breathable construction beneath, it offers a more comfortable feel without the density that can trap heat in some deeper foam designs.
Construction
Pillowtop comfort layer with supportive base
Cooling benefit
Breathable cover and surface layers help reduce heat at contact
Feel
Soft, cushioned surface with a lighter, more breathable finish
Why we recommend it
If you notice heat most at the surface rather than deeper in the mattress, this is a sensible option. It focuses on improving the feel where your body makes contact, which can make a noticeable difference to overall comfort.
Beyond the mattress: other things that help
The mattress is the biggest lever, but it’s not the only one.
Cooling mattress toppers
If replacing your mattress is not the right move right now, a cooling mattress topper can make a meaningful difference to the sleeping surface. Gel infused memory foam and latex toppers can help draw heat away from the body overnight. Look for options with breathable or moisture wicking covers such as CoolMax, which help regulate temperature while maintaining comfort.
Cooling pillows
Your pillow is in direct contact with your head and neck throughout the night, which is where a significant amount of heat is generated. Cooling pillows with gel layers, ventilated foam, or breathable fabrics can improve airflow and reduce heat build up. These can complement a cooling mattress or make a noticeable difference on their own.
Bedding choices
Natural fibre bedding, particularly linen and cotton, is far more breathable than many synthetic alternatives. Linen is especially effective due to its moisture wicking properties and ability to regulate temperature. Investing in breathable bedding can enhance the performance of any mattress.
Room temperature
The ideal bedroom temperature for sleep is generally between 15 and 19 degrees Celsius. Even the best cooling mattress will struggle in a room that is consistently too warm. Simple changes such as improving airflow, using blackout curtains during the day, and positioning a fan to circulate air can make a meaningful difference to overall sleep comfort.
Frequently asked questions
Do cooling mattresses actually work?
Yes, although the effectiveness varies depending on the materials used. Latex and gel-infused mattresses are designed to improve airflow and reduce heat retention. The key is to look for breathable construction and proven cooling features rather than relying on general claims.
Is memory foam bad for hot sleepers?
Standard memory foam can feel warmer because it responds to body heat and contours closely to the body, which can reduce airflow. However, gel-infused or open cell memory foam is designed to improve breathability. If heat retention is your main concern, latex or pocket sprung mattresses with natural fillings are often cooler alternatives.
What is a dual seasons mattress?
A dual seasons mattress has two different sleeping surfaces. One is designed for warmer months and the other for cooler conditions. The mattress is turned seasonally, allowing each side to provide a more suitable sleep environment depending on the time of year.
Can a mattress topper help if I sleep hot?
Yes, particularly if your current mattress is otherwise suitable but feels too warm. A latex or gel-infused topper can help reduce heat build up at the surface. While it will not replace the performance of a cooling mattress, it can be an effective and more affordable improvement.
Are cooling mattresses good for couples?
They can be a very good option, particularly pocket sprung or hybrid designs that also offer good motion isolation. If partners have different temperature preferences, a dual seasons mattress can be especially practical as it allows for better year-round comfort without compromise.
Need help choosing?
Temperature experience is genuinely personal, what keeps one person perfectly cool may not be enough for another, and the right solution depends on how you sleep, your body type, and how warm your bedroom gets. Our team at Land of Beds are happy to talk through the options without any pressure.
