Have you ever woken up in the middle of the night feeling sweaty, restless, and uncomfortable? I have and if you’re reading this, you probably have too. Overheating during sleep is one of the most common reasons people wake up tired, groggy, or with headaches. And in the increasingly warm UK summers, finding the coolest mattress in UK has become more than just a luxury, it’s a necessity.
In this complete guide, we’ll explore what is the coolest mattress, dive into the coolest mattress types, and highlight the best mattresses that truly live up to the promise of keeping you cool all night long.
Why Does Overheating Disrupt Sleep?
Before jumping into the best cooling mattresses, let’s look at why your current mattress might be causing heat buildup in the first place.
During sleep, your core body temperature drops slightly to help your brain and body rest. However, many traditional mattresses, especially those made from dense, closed-cell memory foam, trap your body heat against you. Instead of dissipating heat, these materials reflect it back, disrupting your natural sleep cycle.
The result? Tossing, turning, night sweats, and interrupted sleep stages. And it gets worse during summer months when the ambient room temperature is already high.
What Makes the Coolest Mattress Type?
To stay cool while sleeping, a mattress needs to actively regulate temperature, not just passively absorb heat. So when people ask, “What is the coolest mattress?” the answer depends on materials and design.
Here are the top features of the coolest mattress types:
1. Gel-Infused Memory Foam
Gel particles embedded into foam layers draw heat away from the body. Unlike traditional memory foam, which absorbs heat and retains it, gel-infused foams offer a much cooler sleeping surface.
2. Phase Change Materials (PCMs)
PCMs adjust to your body temperature dynamically. These high-tech materials absorb heat when your body is too warm and release it when you cool down, Phase Change Materials keeping you in the ideal sleep temperature zone all night.
3. Hybrid Mattress Construction
The coolest mattress in UK often combines memory foam and pocket springs. The coil system improves airflow and prevents heat build-up while offering motion isolation and support.
4. Natural Latex and Open-Cell Foam
Latex is naturally breathable, antimicrobial, and temperature neutral. Open-cell foam improves airflow, allowing heat to escape quickly from the surface.
5. Breathable and Moisture-Wicking Covers
A good mattress cover matters. Bamboo, cotton, and Tencel are excellent for moisture-wicking and ventilation, keeping your body drier and cooler through humid nights.

From this, it’s clear the coolest mattress type is a hybrid mattress with gel foam and pocket springs, like the LuxeTherm™.
What Else Can You Do for Cooler Sleep?
Even the most advanced cooling mattress can’t work in isolation, your overall sleep environment plays a huge role in how cool and comfortable you feel throughout the night. By optimising your bedding, room temperature, and sleep habits, you can enhance the effectiveness of your mattress and enjoy more restful, sweat-free sleep.
Cool Sleep Tips That Work:
- Use lightweight, breathable bedding: Swap out heavy duvets and polyester sheets for breathable materials like bamboo, organic cotton, or Tencel. These fabrics wick moisture away from the body and allow airflow throughout the night.
- Keep your bedroom between 16°C and 20°C: This is the optimal temperature range for sleep, according to sleep specialists. Anything warmer, and your body might struggle to cool down naturally.
- Choose moisture-wicking sleepwear: Lightweight pyjamas made from bamboo or athletic-grade fabrics can help keep your body dry and cool, especially if you’re prone to night sweats.
- Use fans or air circulators strategically: A fan placed at the foot of your bed or near an open window can create cross-ventilation and help lower room temperature naturally.
- Avoid heavy meals and caffeine before bed: Digestion and stimulants like caffeine can raise your internal temperature, making it harder to fall and stay asleep. Aim to stop eating 2–3 hours before bedtime.
- Block out sunlight and insulate windows: Blackout curtains not only improve melatonin production by creating darkness, but they also keep your room cooler during the day by blocking out heat from the sun.
These changes may seem simple, but together with a temperature-regulating mattress, they can significantly reduce night sweats and restless tossing.
What is the Coolest Mattress for You?
So, what is the coolest mattress in the UK? The answer isn’t one-size-fits-all, it depends on your sleep position, body type, and how much you tend to heat up during the night. Here’s a breakdown to help you choose the right cooling mattress based on your needs:
For Back Sleepers:
LuxeTherm™ Hybrid and LuxeNova™ Hybrid are both excellent choices. These mattresses provide the right level of firmness to keep the spine aligned while incorporating gel-infused foams and ventilated spring systems that prevent overheating. The contouring nature of memory foam combined with air channels in the spring layers offers optimal support and temperature regulation.
For Side Sleepers:
Consider the Luxe Velour (not previously listed but a great plush option if available). Side sleepers generally benefit from a softer surface to cushion the shoulders and hips, and natural materials like latex or gel foam can help dissipate heat while offering gentle contouring.
For Couples:
LuxeNova™ Hybrid and LuxeTherm™ Hybrid excel here thanks to their individual pocket springs and motion isolation features. They also regulate temperature evenly across the surface—perfect when one partner sleeps warmer than the other. These models balance pressure relief, bounce, and breathability.
For Eco-Conscious Buyers:
The Luxe Natural™ Pillow Top Mattress is ideal. It features organic materials like British wool, natural latex, and cotton, all of which are inherently breathable and temperature neutral. These natural fibers regulate temperature without relying on synthetic additives, making it a great choice for green living and cool sleep.

Frequently Asked Questions – Cooling Mattresses
1. What causes overheating on a mattress?
Overheating happens when mattresses made of dense materials, like traditional memory foam, trap your body heat. Instead of allowing it to escape, they reflect it back, making you too warm while you sleep.
2. How does body temperature affect sleep quality?
As you sleep, your core temperature naturally drops. When it doesn’t—due to heat-trapping materials—it disrupts your sleep cycle, particularly deep and REM stages, causing restless nights and frequent awakenings.
3. Are cooling mattresses effective in summer?
Yes. Cooling mattresses are designed to regulate temperature using gel foams, spring systems, and breathable covers, making them ideal for hot summer nights or warm bedrooms.
4. What features should I look for in a cooling mattress?
Look for gel-infused memory foam, phase change materials (PCMs), natural latex, open-cell foams, and breathable fabrics like bamboo or Tencel for moisture wicking and airflow.
5. Can the mattress cover help reduce overheating?
Absolutely. A breathable, moisture-wicking cover made from bamboo, cotton, or Tencel can significantly reduce heat build-up and keep your sleeping surface cooler.
6. Do hybrid mattresses stay cooler than all-foam ones?
Yes. Hybrids typically include a coil base that improves airflow through the mattress, making them cooler than dense all-foam mattresses that trap heat.
7. Who should consider a cooling mattress?
Cooling mattresses are ideal for hot sleepers, couples, those living in warm environments, menopausal women, and people experiencing night sweats or sleep disruptions due to heat.
8. Does sleeping cooler actually improve sleep?
Yes. A cooler sleep environment helps your body reach deep and restorative stages of sleep faster, improving sleep quality and reducing wake-ups during the night.
9. How can I enhance my mattress’s cooling abilities?
Pair your cooling mattress with breathable bedding, moisture-wicking sleepwear, and a room temperature between 16°C to 20°C. Use fans or blackout curtains if necessary.
10. Are cooling mattresses worth it?
If overheating is disturbing your sleep, then absolutely. Cooling mattresses help regulate temperature and improve overall sleep quality, making them a smart long-term investment.
