Emma mattress composition
The Emma Sleep Original is a high-quality memory foam mattress.
It features three foam layers that work together to offer optimal comfort, stability, and spinal support.
The three different foam layers are:
- A top layer of point-elastic Airgocell foam (3 cm / 1.1 inches)
- A core of high-density, pressure-relieving memory foam (3 cm / 1.1 inches)
- A base layer High Resiliency Extra (HRX) polyfoam with contour zones (19 cm / 7.4 inches)
These are all high-density foams, indicative of high quality, durability, and a good mattress lifespan.
Let's take a closer look at each of these foam layers.
The Emma mattress foam layers
Each of the foam layers in the Emma Original serves a specific purpose.
1. Point-elastic Airgocell foam
The top comfort layer of the mattress is made from patented Airgocell foam.
The unique Point Elastic Airgocell technology enhances overall breathability and regulates temperature within the mattress by allowing excess heat to escape.
This counteracts the heat-retention properties of memory foam, designed to keep you cooler than standard foam mattresses. ❄️
2. Halo memory foam
The core of the mattress consists of high-density memory foam.
The Halo memory foam adapts optimally to your body shape.
This offers targeted spinal alignment, enhanced pressure relief, and body-hugging comfort. 🤗
The memory foam layer in the Emma Sleep Original is relatively thin.
This isn't a bad thing: It means you can enjoy the benefits of the foam without the drawbacks, such as excessive heat retention and difficulty moving.
3. Emma HRX Supreme foam
The base of the Original mattress consists of Emma HRX (High Resiliency Extra) Supreme foam.
This base foam layer serves multiple purposes:
- It guarantees durability by preventing sag.
- Five adaptive contour zones distribute body weight more evenly.
- Limits motion transfer to keep you comfortable.
Overall, the HRX cold foam gives you enhanced support and stability. 🏋️♂️
It also ensures the durability of the mattress.
However, you should rotate your mattress every couple of months to further improve the mattress's durability.
This will help to evenly distribute weight and avoid the development of body impressions.
Emma mattress cover
The Emma memory foam mattress includes a simple yet elegantly designed cover.
However, we tested the Emma Original Plus, which includes the more advanced Comfort cover, previously known as the Diamond Hybrid cover.
The table below breaks down the differences between the covers:
Standard Emma cover | Emma Comfort cover | |
Design: | Thinner, textured design with grey mesh border. | Honeycomb design with green accents and grey mesh border. |
Materials: | 99% polyester and 1% elastane. | 99% polyester and 1% elastane. |
The main difference in the Comfort cover is the luxury honeycomb design.
Emma claims the Comfort cover has better thermoregulation, with the honeycomb design providing better airflow.
The Comfort cover is thick and luxurious, incredibly soft, and pleasant to lie on.
Side carrying handles
The cover has four carrying handles, which make moving the mattress or turning it around much more manageable.
Unfortunately, the handles are relatively weak and can tear quickly.
This is especially true if you're handling the mattress more roughly or dealing with one of the larger mattress sizes.
Can you wash the Emma mattress cover?
Conveniently, you can wash the Emma cover.
We encountered no issues in detaching and reattaching the cover - in fact, we discovered that it could be accomplished by just one person.
Simply zip it off and machine-wash at 60℃. 🛀
A mattress with a machine-washable cover like the Original Emma is an excellent hypoallergenic choice [1] suitable for people prone to allergies.
That said, we always recommend investing in a mattress protector to further safeguard your mattress against stains, spills, dirt, and bacteria. 💦
This will also elongate the lifespan of your mattress.

How comfortable is the Emma Original mattress?
Our test sleepers tried the Original for quite a while for our UK Emma mattress review.
Their best description of what sleeping on the mattress feels like was "cosy and supportive".
This feeling can largely be explained by the combination of the two upper comfort layers.
Both Airgocell and memory foam are highly adaptable and conform to the shape of your body. 🤗
They are also very point-elastic, meaning they can relieve pressure well and help your muscles relax.
With this combination, you should feel as if you're sinking into a cloud, ready to drift off for the best night's sleep of your life.
Here's what one of our sleep experts said:
What a pleasant discovery - the adaptability of this mattress is excellent! Definitely a first in my experience. This mattress 'hugs' the body well, regardless of your sleeping position. It feels a bit like you're sleeping in a cocoon. And it really allows your muscles to relax!

Is the Emma mattress good for side sleepers?
Since the Emma memory foam mattress is a medium-feel mattress, it's exceptionally comfortable when sleeping on your side.
This is because your shoulders and hips - the heavier parts of your body - can sink into the mattress more deeply.
Yet, it still offers enough support for the lighter parts of your body, like your feet and arms. 🦶
This combination allows your spine to remain in optimal alignment.
Look at the image below as an illustration:
You can see how the soft foam layers contour around the body shape, gently cushioning the hip and shoulder.
Meanwhile, the Emma mattress provides enough stability to keep the spine lifted and aligned with the neck.
Our female and male testers experienced exceptional comfort in the side sleeping position.
Both testers agreed the Emma Original mattress reduced aches and pains and provided a supportive yet snuggly sleep.
Is the Emma mattress good for bad backs?
The Emma is a brilliant choice if you're looking for an orthopaedic mattress to help reduce back pain.
If you have a bad back or some orthopaedic concerns, you want to be searching for optimal spinal alignment. 🦴
Take a look at how the Emma mattress supports the spine when sleeping on your back:
In the back position, the Emma mattress moulds around the heavier parts of the body while aligning the spine in a neutral position.
The mattress also distributes pressure well, allowing your muscles to relax fully and further relieve any tension you may be experiencing.
Not the best support for stomach sleepers or larger builds
While the Emma Sleep memory foam mattress is quite supportive, it may be too soft for heavier-weight sleepers (averaging 90 kg / 198 lbs or more) who sleep purely on their back or stomach.
Larger builds and stomach sleepers require more hip support.
A mattress that is too soft misaligns the spine and can lead to lower back pain.
We tested the Emma Original mattress in the stomach sleeping position:
You can see how the combination of the soft Emma mattress and firm Emma Premium pillow creates an uncomfortable bend in the spine.
If you're of a larger build or prefer sleeping on your stomach, you may find a firmer, more supportive mattress like the Origin mattress or DreamCloud Luxury Hybrid, more comfortable. 👌
Are Emma mattresses firm?
The Emma Original is rated as a medium-firm mattress, but we found it falls a little on the firmer side.
We'd rate it at 7 out of 10 on the Sleep Hero firmness scale, where 1 is the softest and 10 is the firmest.
The Emma mattress offers that sleeping-on-a-cloud feeling but still provides sufficient support and stability, allowing you to enjoy your best night's sleep.
Measuring sinkage depths
To test the Emma mattress firmness, we measured how deeply our test sleepers sank into the foams in various positions. 🧮
Sinkage is a good indicator of how supportive the mattress would be for different sleepers.
To test, we relied on two different sleepers and measured their respective sinkage depths.
The Emma mattress had moderate sinkage in the middle, with slightly more sinkage than other memory foam mattresses like the Nectar mattress.
We also analysed the sinkage depths in different sleeping positions to see how much the mattress adapted to our shape.
To do this, we measured the hips and shoulders to get an indication of how well the Emma Original moulded to these heavier regions.
Our experiment gave the following results:
Female tester (57 kg / 9 st) | Male tester (88 kg / 14 st) | |
Sleeping on the back |
Shoulder: 3 cm (1.18") Pelvis: 3 cm (1.18") |
Shoulder: 1 cm (0.39") Pelvis: 5 cm (1.96") |
Sleeping on the side |
Shoulder: 5 cm (1.96") Pelvis: 6 cm (2.36") |
Shoulder: 6 cm (2.36") Pelvis: 5 cm (1.96") |
Sleeping on the stomach |
Shoulder: 0.5 cm (0.19") Pelvis: 1 cm (0.39") |
Shoulder: 2 cm (0.78") Pelvis: 3.5 (1.37") |
The results were impressive. 🤯
As you can see, the Emma Original is highly adaptable to each sleeping position, offering more sinkage when sleeping on the side and providing more stability when sleeping on the back and front.
The Emma mattress also adjusted well to different weights, distributing the weight evenly across the mattress's surface.
However, we'd say it's a little too soft for heavier stomach sleepers.
Edge support test
If you often sit on the edge of your bed, it's important to choose a mattress that has good edge support.
As the name suggests, this is the support you can experience at the very edge of the mattress.
In a mattress with bad edge support, you'll feel as if you're sliding off the mattress when sitting on the edge or sleeping very close to the edge of the mattress.
Take a look at the edge support of the Emma mattress:
Overall, we found it had average edge support.
But it did fare a little better than other all-foam mattresses like the Nectar mattress.
However, firmer bed-in-a-box options that combine pocket springs with foam layers generally do better in our edge support test.
If you like sitting on the edge of your bed, it's best to look for a mattress with better edge support, like the DreamCloud Luxury Hybrid mattress.
Does the Emma mattress sleep hot?
You may have heard that memory foam sleeps hot. 🥵
This is true.
Memory foam mattresses are generally warmer and retain more heat than other mattresses.
But the Emma Original mattress is designed with temperature-regulating properties.
The Airgocell layer and the fine-meshed top cover are acclaimed to increase breathability and reduce heat storage. ❄️
But how well do these thermal properties really work?
Testing heat retention in the Emma Original
We used a thermal camera to analyse how much heat was retained in the Emma mattress upon waking up. 📷
Since we usually wake up warmer than when we go to sleep, this provides a good indication of the warmest we'd be on the Emma Original mattress.
Take a look at the results:
As you can see, the Emma Original retained much of the heat built up inside the mattress, providing an average temperature of 37.4 -37.5°C
This is 11.7°C warmer than our tester's results on the Emma Premium mattress, a hybrid mattress with a pocket spring layer, which provides better airflow. 🌬️
However, there are other variables to consider:
- The room temperature was 25°C on the thermostat
- Our testers were using the Emma Cloud duvet
- Our tester's sheets were 90% polyester, 10% cotton
- Our testers slept with a fan in the room during the night
The results from our temperature test correlate with how warm we felt sleeping on the Emma mattress.
On particularly warm nights, we woke up overheating, and you could feel the heat retained by hovering your hand above its surface.
Therefore, if you feel warm easily during sleep, you should consider a cool mattress, like the Simba Hybrid Luxe, which is designed with the most breathable materials.
Is the Emma mattress good for couples?
If you're sharing your bed with a partner, you'll have one burning question:
Can I comfortably share this mattress with another person?
There are two factors we consider to determine this:
- Edge support
- Motion transfer
We've already seen that the Emma Original UK mattress has average edge support.
While the Emma mattress double is the minimum size for couples, we recommend couples invest in a larger mattress, such as the Emma mattress king size or the super king-sized mattress.
Larger mattress sizes ensure that both partners have enough space to sleep comfortably.
But what about motion transfer?
Motion transfer refers to how much movement is carried through the mattress.
That is: Will you feel your partner toss and turn or get into bed when you're already fast asleep?
A mattress with high motion transfer isn't ideal as you'll feel movements quite well.
The Emma Original has exceptionally low motion transfer (or, good motion isolation).
The foam layers absorb and dampen movements, ensuring that motion is not carried across the mattress.
When we did our Emma mattress review UK, we shared the bed with a partner - and did not feel any movements.
Despite the difference in weight between the two people lying on the mattress, we did not experience the feeling of "rolling" towards the heavier partner. That said, the mattress will be less suitable for overweight people because I am not certain that the foam restores all of its elasticity after changing your sleeping position.

We also didn't feel our partner getting in and out of bed.
This means you can enjoy a restful night's sleep and won't be disturbed by your partner tossing and turning. 🕺
Emma Original mattress sizes
Emma Sleep mattresses are available in all standard UK sizes. 🇬🇧
These include:
- Emma mattress single: 90 x 190 cm (3’ x 6’3”)

Our mattress size guide can also help you choose the perfect mattress.
How thick is the Emma mattress?
The Emma mattress depth lies at 25 cm (9.8").
This is standard for most bed-in-a-box mattresses.
We love standard-sized mattresses, as this means most bedding will fit comfortably. 😅
Unfortunately, our mattress was a couple of centimetres shy of 25 cm (9.8"), measuring 22.5 cm (8.8").
However, we opened it later than the recommended period, which could have played a role in its lack of full expansion.
To maximise your Emma mattress's performance, it's best to unbox it within 4 weeks of receiving your shipment.
Should your Emma mattress fail to reach the specified height, it is advisable to contact the Emma support team, as this issue is considered under your warranty.

How does the Emma memory foam mattress expand?
If you're new to bed-in-a-box mattresses [2], you may be wondering how you'll get a full-size comfortable mattress out of the delivery box. 🤯
Emma mattress instructions:
- Place the box on your bed frame.
- Take out the still-rolled-up mattress.
- Cut open the plastic wrapping.
- Unfold your mattress.
- Take away all the excess wrapping.
The mattress expands almost instantly as soon as you break the vacuum seal and start removing the packaging.
However, we were delayed in unboxing our new mattress, which slowed down the expansion process.
Because of this, it took around 24 hours for our Emma mattress to fully expand. ⏰
For best results, you should unbox your mattress within 4 weeks of receiving it.
You can sleep on your Emma memory foam mattress as soon as it has reached its full size.
Off-gassing is completely normal
When you first unpack the mattress, you may notice a slight odour, referred to as off-gassing.
Off-gassing is neither toxic nor harmful, but it can be a little uncomfortable.
We recommend unpacking your new mattress in a well-ventilated room and letting it air out.
The mattress we received only had a slight chemical smell, and it disappeared after a few hours.
Does the Emma mattress come with a trial period?
The Emma Original comes standard with a 200-night risk-free trial period, which begins with delivery. 🚚
This is great as it gives you even more time to try out the mattress in the comfort of your own home.
That being said, you shouldn't feel put off by your mattress if it's not comfortable on the first night.
After all, it can take 4 - 6 weeks to get used to a new mattress, and you won't know for sure if it's right for you until you've spent some time sleeping on it.
If you wake up with back pains or can't sleep well even after 6 weeks, the mattress might not be suitable for you.
Does your Emma mattress feel too soft or firm?
You can contact the Emma support team, who will happily send you an additional soft or firm comfort layer.
Emma is one of the only brands we know of that offers this service.
Emma mattress returns
If at any point during the trial period you decide the mattress isn't right for you, you can return it.
Returns are free and organised and paid for by Emma UK.
Returns are also super easy - simply contact Emma's customer service via the returns portal.
You'll receive a full refund within 14 working days. 💰
There is no need to keep your Emma box or any original packaging to make use of the Emma returns process.
If you decide to return your Emma Original, the couriers ordered to pick up the mattress will arrive with the packing materials.
Are Emma mattresses any good and should you buy one?
