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.
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 regularly to further improve the mattress's durability.
This will help to evenly distribute weight and avoid the development of body impressions.
We advise rotating your mattress once every couple of months.
Emma mattress firmness
The Emma Original is rated as a medium-firm mattress.
And after sleeping on this mattress for several weeks, we'd have to agree. 🧸
We'd rate it at 6 out of 10 on the Sleep Hero firmness scale, where 1 is the softest and 10 is the firmest.
This puts it on par with the Simba Hybrid, one of our favourite hybrid options.
It 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 sinking depths in different sleeping positions.
We tested this by laying at the very end of the mattress and seeing how much the mattress adapted to our shape.
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 (9 st / 57 kg)||Male tester (14 st / 88 kg)|
|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 sit on the end of your bed, it's important to choose a mattress that has good edge support.
But what exactly is 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.
This is to be expected with softer mattresses, and not everyone minds bad edge support. ⛰️
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.
Choose a mattress with good edge support if you:
- Like using the entire width of the mattress.
- Enjoy your mattress for other activities, like painting your nails or working on your laptop.
- Like sitting on the edge of your bed to read, browse your phone, or put on your shoes.
- Share your bed with a partner.
If you like sitting on the edge of your bed, it's best to look for a mattress with better edge support.
The DreamCloud Luxury Hybrid mattress has excellent edge support.
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?
Well, first, what is 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 third 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. 🇬🇧

- EU single: 90 x 200 cm (3' x 6'7")
- EU double: 140 x 200 cm (4'7" x 6'7")

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.

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. 🚚
Emma used to offer a 100-night trial, but the UK's trial period has since been extended.
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.
