Yes, traditional memory foam mattresses do retain more heat than many other mattress types because the dense, closed-cell foam restricts airflow and holds onto body heat.
Modern cooling memory foam has improved significantly. Features such as open-cell foam, gel infusions, graphite and breathable comfort layers help move heat away from the body and can reduce heat build-up by around 1–3°C compared with traditional memory foam.
If you enjoy the pressure relief of memory foam but tend to sleep warm, a hybrid mattress is often the best compromise. If staying cool is your number one priority, a pocket spring mattress will usually provide the best airflow and coolest night’s sleep.
Why Memory Foam Got Hot (Literally)
If you’ve ever climbed into bed thinking your memory foam mattress feels wonderfully cosy, only to wake up a few hours later searching for the cool side of the pillow, you’re certainly not alone. To understand why that happens, it helps to know where memory foam came from.
The story actually begins with NASA. During the 1960s, researchers working on behalf of the space programme developed an early version of viscoelastic foam to improve cushioning and absorb impact. Over the following decades, that same technology found its way into mattresses, where it became famous for its ability to contour around the body and relieve pressure.
The very thing that makes memory foam feel so luxurious is also what gave it a reputation for sleeping warm. Traditional memory foam has a dense structure that gently moulds around your shoulders, hips and lower back, helping to spread your weight more evenly. The trade-off is that this dense structure naturally restricts airflow, meaning your body heat is absorbed into the foam instead of escaping.
For the first twenty minutes, that can feel wonderfully comfortable. By two o’clock in the morning, especially if you’re naturally a warm sleeper, it can be a different story. You might find yourself kicking off the duvet, flipping your pillow to the cool side or changing position in search of somewhere cooler. If that sounds familiar, you’re not imagining it.
The good news is that today’s memory foam mattresses aren’t the same as the ones that earned this reputation. Manufacturers have spent years developing cooling technologies that improve airflow without sacrificing the pressure relief people love. We’ll look at exactly how those innovations work in the next section.
“Heat retention isn’t a defect in traditional memory foam. It’s simply a natural result of how viscoelastic foam responds to your body. The same structure that cushions pressure points also absorbs and stores warmth. Today’s cooling technologies don’t change how memory foam works. They’re designed to improve airflow and help that heat escape more efficiently.”
How Modern Memory Foam Has Evolved
If your only experience of memory foam comes from a mattress you tried ten or fifteen years ago, you might be surprised by how much the technology has changed. While traditional memory foam was known for retaining heat, today’s premium mattresses are designed very differently.
Manufacturers now combine multiple cooling technologies instead of relying on a single solution. Open-cell foam structures allow air to move more freely through the mattress, gel and graphite infusions help transfer heat away from the body, while breathable covers and hybrid constructions improve airflow without sacrificing the pressure relief memory foam is known for.
Many of the best memory foam mattresses now use several of these innovations together. Rather than trying to eliminate heat completely, the aim is to create a more balanced sleep environment that delivers the contouring comfort of memory foam while helping you stay cooler throughout the night.

What warm sleepers should know
-
✕
It can retain heat
Traditional memory foam absorbs body heat more readily than spring-based mattresses. -
✕
Less natural airflow
Dense foam doesn’t circulate air as freely as pocket springs or hybrid designs. -
✕
Moisture can build up
If you sweat during the night, some foams can feel warmer or slightly clammy. -
✕
The “hugging” feeling isn’t for everyone
Some sleepers love the cocooning sensation, while others prefer to sleep more “on” their mattress. -
✕
There may be a temporary new mattress smell
Some foam mattresses have a mild odour when first unboxed, but this usually disappears within a few days.
Which Mattress Is Right for You?
Rather than asking whether memory foam is “good” or “bad”, it’s more helpful to think about how you sleep. Here’s a quick guide to help you decide which mattress type is most likely to suit your needs.
| If you… | Our recommendation | Why |
|---|---|---|
| Sleep on your side and often wake up with sore shoulders or hips | Memory Foam | Excellent pressure relief helps cushion sensitive joints and encourages better spinal alignment. |
| Love the feeling of memory foam but regularly sleep hot | Cooling Hybrid Mattress | Combines pressure-relieving foam with breathable pocket springs for improved airflow. |
| Wake up feeling too warm most nights | Pocket Spring or Hybrid Mattress | Open spring structures allow much better air circulation than traditional all-foam mattresses. |
| Share your bed with a restless partner | Memory Foam or Hybrid | Both offer excellent motion isolation while reducing movement across the mattress. |
| Prefer to sleep on your mattress rather than in it | Pocket Spring | Provides a more responsive feel with less of the body-hugging sensation memory foam is known for. |
| Want the best all-round balance of comfort and cooling | Hybrid Mattress | For many people, hybrids offer the sweet spot between pressure relief, support and temperature regulation. |
Remember: The best mattress isn’t the one with the most features or the highest price tag. It’s the one that suits your body, your sleeping position and your temperature preferences. If staying cool is a priority but you still want the comfort of memory foam, a modern hybrid mattress is often the best place to start.
Do Cooling Memory Foam Mattresses Really Work?
If you’ve started shopping for a memory foam mattress, you’ve probably seen terms like gel-infused, graphite cooling, PCM and cool-touch covers. They all promise a cooler night’s sleep, but they don’t all deliver the same results. Here’s what actually makes a difference and what’s largely clever marketing.
✔ Technologies we’d actively look for
Open-Cell Memory Foam
One of the most effective improvements to traditional memory foam. Tiny air pockets allow more airflow through the foam, helping heat escape more easily without compromising pressure relief.
Graphite Infusion
Graphite is naturally conductive, helping transfer heat away from your body faster than standard foam. It’s generally more effective throughout the night than gel alone.
Hybrid Construction
Our favourite solution for hot sleepers. Pocket springs create natural airflow underneath the comfort layers, making hybrid mattresses noticeably cooler than traditional all-foam designs.
✓ Helpful, but don’t expect miracles
Gel-Infused Foam
Gel beads absorb heat quickly, creating a cooler feel when you first get into bed. The effect is genuine, but it’s usually most noticeable during the first few hours of sleep.
Cooling Mattress Covers
Materials such as TENCEL™, GlacioTex and other moisture-wicking fabrics can make the mattress surface feel cooler and drier, particularly if you sweat during the night.
Phase Change Materials (PCM)
PCM absorbs and releases heat as your temperature changes. The science is sound, but the real-world cooling effect depends on how much of the material is actually used.
✕ Marketing terms we’d treat with caution
“Temperature Neutral”
There’s no recognised industry definition for this phrase. Every sleeper generates different amounts of body heat, so no mattress can realistically feel temperature neutral for everyone.
“Ice” or “Arctic” Cooling
These names often describe branding rather than a specific technology. Look beyond the product name and check which materials are actually being used.
“Ultimate Cooling”
If a brand makes bold cooling claims without explaining how the mattress achieves them, it’s worth being sceptical. Good manufacturers are transparent about the technology they use.
Here’s something many mattress brands don’t tell you: memory foam and airflow naturally work against one another.
The reason memory foam feels so comfortable is because it moulds closely around your body, increasing the surface area in contact with the mattress. That same close contact reduces airflow around you, which is why traditional memory foam sleeps warmer than open spring mattresses.
Modern cooling technologies help manage this heat, but they don’t completely change the way memory foam behaves. That’s why many sleep experts recommend hybrid mattresses for people who love the pressure relief of memory foam but naturally sleep hot. They combine breathable pocket springs with responsive foam, giving you the best balance of contouring, support and airflow.
The Best Mattress for Hot Sleepers Who Still Want Pressure Relief
By now, we’ve established that traditional memory foam isn’t always the coolest choice. That doesn’t mean you have to give up the pressure relief that made you consider memory foam in the first place. Modern mattress technology offers several ways to enjoy a more comfortable night’s sleep without waking up feeling overheated. Here are the options we’d recommend most often.
Hybrid Mattress
If you’re looking for the best balance of pressure relief, support and temperature regulation, a hybrid mattress is hard to beat. Pocket springs encourage airflow through the mattress while the comfort layer cushions your shoulders, hips and lower back. For most hot sleepers, this is where we’d start.
Graphite-Infused Memory Foam
If you love that slow-moving, body-contouring feel, graphite-infused memory foam is a worthwhile upgrade. It helps conduct heat away from your body more effectively than traditional memory foam while keeping the pressure relief people love.
Open-Cell Memory Foam
Open-cell memory foam improves airflow through the mattress, helping it feel fresher than older closed-cell foams. It won’t feel as cool as a hybrid, but it’s a noticeable improvement if you’re choosing an all-foam mattress.
Pocket Spring Mattress
If staying cool is your number one priority, a quality pocket spring mattress remains the coolest choice. The open spring structure allows air to circulate naturally throughout the night, although you’ll sacrifice some of the body-hugging feel that memory foam provides.
Which Option Is Best for Your Sleeping Position?
The way you sleep can make just as much difference as the mattress itself. Here’s where we’d usually point customers, based on years of helping people find the right mattress.
| Sleeping Position | Recommended Mattress | Why It Works |
|---|---|---|
| Side Sleeper | Hybrid Mattress | Pressure-relieving comfort layers cushion shoulders and hips, while pocket springs help improve airflow. |
| Back Sleeper | Hybrid or Pocket Spring | Provides excellent spinal support while sleeping noticeably cooler than traditional memory foam. |
| Front Sleeper | Firm Pocket Spring | Helps prevent the hips sinking too deeply while maximising breathability. |
| Combination Sleeper | Hybrid Mattress | A responsive surface makes it easier to move during the night without compromising comfort. |
You don’t have to choose between sleeping cool and sleeping comfortably. If you love the pressure relief of memory foam but naturally sleep warm, a modern hybrid mattress is often the sweet spot. It combines breathable pocket springs with responsive comfort layers, giving you many of the benefits of memory foam without as much heat build-up. If cooling is your only priority, however, a traditional pocket spring mattress is still difficult to beat.
Our Top Mattress Picks for Hot Sleepers
Choosing the right mattress isn’t about finding the coolest model on the market. It’s about finding one that delivers the pressure relief you need without leaving you feeling overheated. These are the three mattresses we’d recommend most often to customers looking for that balance.
Viva Hybrid Supreme
If you’ve read this guide and found yourself thinking, “I love the idea of memory foam, I just don’t want the heat,” this is where we’d point you first.
The Viva Hybrid Supreme combines pressure-relieving memory foam with individually pocketed springs, giving you the contouring comfort memory foam is known for while allowing significantly more airflow than a traditional all-foam mattress. It’s a fantastic choice for side sleepers and combination sleepers who want comfort without feeling too warm overnight.
Sleepeezee Dual Seasons Deluxe
If staying cool is your number one priority, this is the mattress we’d recommend with the most confidence.
The innovative Dual Seasons design lets you choose between a cooler sleeping surface for summer and a warmer side for winter. Combined with breathable British wool and responsive pocket springs, it delivers excellent temperature regulation without relying on thick foam comfort layers.
Relyon Tarporley
If you’re looking for a more affordable way to enjoy the benefits of both memory foam and pocket springs, the Tarporley is an excellent middle ground.
Its responsive memory foam comfort layer cushions pressure points while 1,500 individually pocketed springs improve airflow throughout the mattress. It won’t feel quite as cool as the Sleepeezee Dual Seasons, but it offers a noticeably fresher sleep than a traditional all-memory foam design.
The Verdict: Should You Avoid a Memory Foam Mattress?
Not necessarily. Traditional memory foam does retain more heat than many other mattress types, but that doesn’t automatically make it the wrong choice. If pressure relief, motion isolation and body-contouring comfort are your biggest priorities, memory foam can still be an excellent investment.
The key is choosing the right type of mattress for the way you sleep. Modern hybrid mattresses, breathable comfort materials and improved cooling technologies mean you no longer have to choose between comfort and temperature regulation in the way you once did.
If you sleep hot…
Look for a hybrid mattress, breathable natural fillings or pocket springs that encourage airflow throughout the night.
If pressure relief matters most…
Memory foam remains one of the best materials for cushioning shoulders, hips and lower back, especially for side sleepers.
If you want the best of both…
A modern hybrid mattress often provides the ideal balance of contouring comfort, support and cooling performance.
At Land of Beds, we believe there isn’t a single mattress that’s right for everyone. The best mattress is the one that suits your sleeping position, body shape, temperature preferences and comfort needs. That’s why our sleep experts take the time to understand how you sleep before making a recommendation.
If you’re still unsure, don’t rely on a quick five-minute showroom test. Spend time comparing different mattress types, ask questions and, where available, make the most of a sleep trial so you can experience the mattress in your own bedroom over several weeks. A mattress should support you for years, so it’s worth taking the time to choose with confidence.
