How we test products
Our mission is to take the guesswork out of finding the perfect sleep products.
We've dedicated hundreds of hours to testing mattresses and sleep accessories, and rely on a team of testers of differing weights, temperature preferences, and sleeping positions to evaluate each product.
Tested products are granted the Sleep Hero tested stamp of approval, a mark of our review's reliability.
If we haven't personally tested a product, please be assured that we invest significant time and energy into scouring the UK market and researching the best recommendations, and we work with a team of sleep experts who review our articles, ensuring that the insights we provide are not only relatable but also reliable.
What it feels like to sleep on the Emma Premium mattress
The Emma Premium mattress is soft and comfortable but also offers excellent support and stability. 💪
The upper comfort layers provide much of that sleeping-on-a-cloud feeling you also experience on the Emma Original.
Both Airgocell and memory foam are highly adaptable foams that conform to your body shape.
This provides body-hugging comfort. 🤗
Meanwhile, the supportive spring layer prevents motion disturbance and promotes optimal spinal alignment.
The Emma Premium was very comfortable when testing the side sleeping position. 😴
It provided enough sinkage for side sleepers, allowing heavier body parts to sink in more deeply.
Moreover, we felt supported by the layers, with the body remaining lifted and the spine neutrally aligned.
See how the mattress contours around the body in the side position:
However, it might feel a bit too firm for lightweight side sleepers who may not sink as deeply.
Experiencing aches in the joints or back might indicate you need a softer mattress.
The Emma Premium is most comfortable for back sleepers. 👍
The back remained straight for both male and female testers, while foam layer contoured around the pelvis, providing pressure relief in this area.
This makes the Emma Premium an excellent mattress for orthopaedic concerns and ensures you won't wake up with lower back pain or tension.
See how the mattress contours around the hips:
As a medium-firm mattress, the Emma Premium provides the perfect balance of support and comfort in this position.
The Emma Premium is a suitable choice for lightweight stomach sleepers.
However, our testers experienced some discomfort when sleeping in this position.
You can see a very slight bend in the lower back:
The Emma Premium mattress might not be suitable if you feel neck or back pain.
We'd recommend the Origin Hybrid mattress for stomach sleepers looking for firmer support. 🧱

Does the Emma Premium sleep hot?
The Emma Premium mattress is designed to enhance breathability. 🌬️
This design includes:
- An UltraDry cover with moisture-wicking technology
- Point Elastic Airgocell technology for temperature regulation
- AeroFlex spring technology that promotes airflow
Memory foam generally retains more heat than other types of foam, making it unsuitable for people who prefer a cooler sleep.
But the hybrid design promotes air circulation, making this a cooler option than all-foam mattresses.
How does the Emma Premium match up?
We used a thermographic camera to see how well the Emma Premium regulated our temperature. 🌡️
One tester pointed the thermographic camera at our sleeping tester in the morning before they woke up.
Our bodies naturally cool down during the night and return to normal in the morning, so this gave us a good indication of the warmest the Emma Premium would feel during sleep.
Take a look at our results:
Our male sleeper, who typically sleeps hot, experienced results of 32.1°C, while our cooler female tester averaged a temperature of 25.7°C.
These results are significantly higher than the recommended sleeping temperature of 18.3°C (65°F).
Both testers agreed they felt reasonably warmer on the Emma Premium than on other hybrid mattresses like the Simba Hybrid.
Therefore, we'd recommend hot sleepers opt for a cooler mattress option.
However, other factors are at play that can contribute to how hot or cold you feel during sleep.
We considered these variables:
- The room temperature was 21°C on the thermostat
- Our testers were using an 8.0 tog duck-down duvet
- Our tester's sheets were 90% polyester, 10% cotton
These factors seem minimal but can make a big difference in your overall temperature.
If you sleep hot, we recommend keeping the room cool and opting for a lighter tog duvet and natural sheets, which are much more breathable. ❄️

Emma Premium mattress composition
The Emma Premium is a five-layer luxury mattress that combines various high-quality foams with a core of 12.5 cm (4.9 inches) pocket springs.
One of Emma's most advanced and innovative mattresses. 🥳
This is a no-turn mattress with a specific right way up, but you still need to rotate the mattress regularly.
Regularly turning your mattress can prevent it from dipping and creating an uneven surface, enhancing its lifespan and overall comfort.
The foam layers, from top to bottom:
- A top comfort layer of breathable Halo memory foam.
- A layer of Airgocell foam.
- A secondary layer of Airgocell memory foam.
- A spring layer of 12.5 cm (4.9 inches) individually wrapped pocket springs.
- Sturdy base layer.
Emma Premium mattress layers
1. Top comfort layer of Halo memory foam
Emma's trademarked Halo foam forms the top comfort layer of the Emma Premium mattress.
This layer is pressure-relieving and body-contouring, providing superior comfort and that "sleeping on a cloud" feeling you can expect from Emma mattresses.
As you can see in the image above, the edges of the foam didn't expand fully.
Typically, a fully-expanded mattress will take on a completely rectangular shape, but with the mattress cover on, this feature was hardly noticeable.
2. Airgocell foam
Visco-elastic memory foam forms the next layer.
Memory foam is often recommended for orthopaedic mattresses as it adapts to the body's shape and relieves pressure well.
This makes the mattress suitable for those struggling with back problems.
The memory foam has been specifically positioned towards the top of the mattress to allow heat to escape. ♨️
One downfall of memory foam is that it retains heat quite well, so it needs to be combined with more breathable materials to reduce the temperature.
The memory foam also provides a final layer of cushioning before the sturdier cold foam and pocket springs.
3. Second layer of Airgocell memory foam
This is an additional cooling layer underneath the memory foam, allowing heat to escape through the bottom of the mattress.
4. Spring layer core with zoned pocket springs
The zoned pocket sprung layer forms the core of the mattress. 💪
In contrast to some other hybrids like the Emma Hybrid or the Simba Hybrid, which feature mini springs, the Emma Premium features a layer of full-sized pocket springs with a height of 12.5 cm (4.9 inches).
This pocket-sprung layer enhances breathability and support.
Each spring is individually wrapped, meaning it can respond to isolated movements, enhancing point elasticity, pressure relief capabilities, and motion isolation.
The pocket spring core is encased by foam walls, allowing for greater stability across the surface of the mattress and enabling edge-to-edge support without the feeling that you'll roll off the mattress if you sleep too far on the side.
5. Base foam layer
The lower foam layer acts as a final supportive and solid base for the mattress.
It has HRX (High Resiliency Extra) for extra stability and support for the spine.
Emma Premium mattress sizes
Emma Premium mattresses are available in most of the standard UK sizes. 🇬🇧
- Emma Premium single mattress: 90 x 190 cm (3’ x 6’3”)
- Emma Premium small double mattress: 120 x 190 cm (4' x 6'3")
- Emma Premium mattress double: 135 x 190 cm (4’6” x 6’3”)
- Emma Premium mattress king size: 150 x 200 cm (5’ x 6’6”)
- Emma Premium super-king-size mattresses: 180 x 200 cm (6’ x 6’6”)
Height of the Emma Premium
The pocket springs measure 12.5 cm (4.9 inches), and the bottom foam layer averages around 5.5 cm (5.5 inches).
The top foam layers are much thinner.
The standard depth/height of the Emma Premium is 25 cm (10").
However, our mattress measured a few centimetres short of this at 20 cm (7.87").
We measured the mattress again a few weeks later, but the height remained unchanged.
A 20 cm (10") depth is fairly low for a mattress - in fact, you can typically find mattresses of this height to be amongst cheap, low-quality options.
For such a premium, costly mattress, it wasn't very reassuring to see that the Emma Premium did not reach its promised height.
Thankfully, a 2 cm (0.7") difference in height is covered by the 10-year guarantee.
If you encounter this problem, contact the Emma customer service team, who will be able to arrange a replacement. ☎️

Emma Original vs Emma Premium
The Emma Premium is Emma's most advanced mattress available in the UK.
The Emma Premium is best described as a mattress with a composition most similar to the Emma Hybrid but with the firmness of the Emma Original.
That makes sense, of course, as the Emma Premium was previously called the Emma Original Hybrid.
The same level of comfort
Like the Emma Original and the Emma Hybrid, this mattress features upper comfort layers of Airgocell foam and memory foam.
This means that you'll get the same level of sleeping-on-a-cloud comfort as you do with those two mattresses. ☁️
We'll give you an overview here, but we highly recommend you read our full Emma Original vs Emma Premium mattress comparison for all the details.
Better support and breathability
But, the Emma Premium also features full-size pocket springs in a foam wall encasing and additional cold foam layers for exceptional point elasticity, edge-to-edge support, stability, and breathability.
The Emma Premium offers far more stability and breathability than the Emma Original and Emma Hybrid.
However, the Emma Premium is still not the most breathable hybrid mattress we've tested. 👎
