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.

Keep in mind that while similar to the Emma One from Emma UK, the Emma One from Amazon is slimmer, measuring just 18 cm (7 inches) instead of 25 cm (9.8 inches).
Composition-wise, the Emma Original is the most similar to the Emma One.
Both the Amazon Emma One and Emma Original are all-foam mattresses, which fall on the softer side of our firmness scale.

If you're looking for a slightly firmer mattress that better matches the original Emma One from Emma UK, the Nectar memory foam mattress would be an excellent choice.

Emma One mattress composition
The Emma One is a foam mattress consisting of three individual layers.
These are:
- A comfort layer of breathable Airgocell foam.
- 7 zones pressure-relieving and cushioning viscoelastic memory foam.
- Supportive HRX cold foam.
Each of the materials used serves a unique purpose.
Let's take a closer look at these layers.

Emma One mattress foam layers
The three layers of the Emma One foam mattress work together optimally to provide comfort and support.
1. Airgocell foam layer
Emma Sleep's unique Airgocell technology is responsible for two key features:
- It provides superior temperature regulation by allowing excess heat to escape.
- It offers excellent point elasticity, allowing one area to be compressed without affecting the rest of the mattress.
This layer counteracts the heat retention properties of memory foam and enhances orthopaedic and motion isolation features. 👩❤️👨
2. Memory foam layer
You'll find very high-quality and high-density memory foam in all of the Emma mattresses.
Memory foam offers body-contouring support for targeted spinal alignment and enhanced pressure relief.
But its excellent pressure-relieving feel isn't the only reason you may want to get a memory foam mattress like the Emma One. 👇
Memory foam mattresses are an excellent choice for anyone looking for orthopaedic support.
3. HRX foam base layer
The majority of the Emma One mattress is made up of a third layer of firmer HRX cold foam.
This provides support and stability for your entire body and ensures the mattress's durability.
The Emma One mattress features contour zones, allowing for more sinkage in some areas and less in others.
This allows the mattress to adapt to your body more optimally and ensures proper spinal alignment.
The Emma One mattress base also features very distinct ventilation channels.
These allow for better air circulation, keeping you cooler and more comfortable throughout the night. ❄️
It also prevents the build-up of mites and bacteria, which prefer warmer and more humid environments.
How firm is the Emma One mattress?
The Amazon Emma One is described as a medium-feel mattress.
However, we would suggest it's actually more of a soft-medium mattress since many Amazon Emma One reviews state it felt softer than they expected. 🐑
The Emma One that was initially sold on Emma Sleep UK felt significantly firmer.
In fact, our testers measured it as an 8 out of 10 on the Sleep Hero firmness scale, where 1 is the softest and 10 is the firmest.
If you are searching for a firmer memory foam mattress, like the original UK Emma One, we'd suggest checking out the Nectar Memory Foam mattress. 🤗
We found it to be a comfortable, 7 out of 10, medium-firm feel.
How comfortable is the Emma One?
When our team tried the original UK Emma One, we found it extremely comfortable, thick, and fairly firm.
While the Emma One sold on Amazon has a similar all-foam composition, it is significantly softer and thinner, so we wouldn't recommend it for long-term use.
Despite these differences, most people still find the Amazon version just as comfortable as we found our Emma One. 😍
Customers generally comment on the body-hugging feel and praise that it doesn't sleep too hot.
15% OFF EMMA ONE MATTRESS£ 169.15
However, this is not always the case, and those who prefer a firmer feel, particularly heavier individuals, will likely find the Amazon version of the Emma One too soft and thin.
Does the Emma One sleep hot?
Memory foam mattresses usually sleep a little warmer than other types of mattresses. 🔥
This is because memory foam retains more heat, which will keep you warmer and more snug throughout the night.
For hot sleepers, this could be problematic.
However, the Emma One counteracts these heat retention properties by introducing a few key features.
These include:
- The Airgocell foam allows for better temperature regulation.
- The ventilation channels ensure good air circulation, carrying away excess heat.
- The top cover is very breathable, allowing heat and moisture to escape.
This creates an environment that's more conducive to a comfortable and temperature-regulated sleep overall. ❄️

That said, if you're a very hot sleeper or heavy sweater, we'd recommend you steer clear of memory foam mattresses.
Hot sleepers fare much better on pocket-sprung or hybrid mattresses.
Spring-based mattresses allow for better air circulation and retain less heat. 🌀
Take a look at some of our recommended cooling mattresses below.

Is the Emma One mattress suitable for couples?
The Emma One is a fantastic mattress for couples. 👩❤️👨
This is due to the following:
- Both lighter-weight and average-weight people find the mattress comfortable, which is great for two people sharing.
- Memory foam limits motion transfer, meaning you won't feel your partner move at night.
- The top layer of Airgocell foam adds a buffer to make the mattress easier to move on, which is not always the case with memory foam mattresses.
We would recommend that couples opt for larger mattress sizes to make their sleeping experience more comfortable.
While a double mattress is a minimum, we'd highly recommend couples opt for king-size or super-king-size mattresses. 👑
These ensure you'll have plenty of room to move on and can enjoy a more comfortable sleep.
Luckily, even the Emma One sold on Amazon is available in a range of sizes, from single mattress to super-king:
Emma One mattress cover
Like most Emma mattresses, the Emma One features a removable mattress cover.
The moisture-wicking cover has been uniquely designed to be breathable, regulate humidity, and enhance air circulation.
Conveniently, the Emma One mattress cover also features 4 robust side handles that make transporting or turning your mattress easier.
The Emma One mattress cover is also fully removable and can be machine-washed at 40°C. 🛀
This makes it an excellent choice for people prone to allergies - and for general hygiene.
15% OFF EMMA ONE MATTRESS£ 169.15
However, the mattress cover is not waterproof, so your mattress foams may stain through sweating or accidental spilling if you don't take measures to safeguard your mattress further.
We always recommend purchasing a waterproof mattress protector, even if your mattress cover is removable.
These affordable accessories can help you avoid stains and extend your mattress's lifespan. ⏳

Where can you buy the Emma One mattress?
Emma Sleep no longer officially sells the Emma One foam mattress in the UK.
However, you can find a softer, lower-height version (measuring 18 cm / 7 inches) on Amazon in the UK.
Emma One on Amazon
The soft-medium Emma One is available on Amazon at fantastic prices!
Conveniently, the Emma One purchased via Amazon comes with a 200-day trial period and a 10-year guarantee.
So you can still get a great deal on this Emma mattress and the additional benefits of buying Emma, even though the mattress is no longer sold through Emma UK.
15% OFF EMMA ONE MATTRESS£ 169.15
However, it should be pointed out that the promised Emma trial and guarantee could be disappointing.
On analysing Amazon reviews, we found some customers had challenges utilising the trial or guarantee and found themselves caught between Amazon and Emma customer services. 😣
Additionally, while most people found the mattress comfortable, we'd still recommend a standard-height mattress (24 cm / 9.4 inches) or higher for regular use.

We suggest buying directly from brands instead of going through retailers like Amazon.
Cutting out the middleman tends to make it easier to get in touch with manufacturers and resolve issues. 👍
If you are looking for a good alternative and want to buy direct from a brand, we suggest checking out the all-foam Emma Original or Nectar Memory Foam mattress.
The Emma Original is most similar to the current softer Emma One, which is currently sold on Amazon, while the Nectar Memory Foam mattress is more similar to the firmer Emma One from the Emma UK website.
What other Emma products can you buy?
In addition to a range of high-quality mattresses, Emma Sleep sells a range of accessories via its official website.
These range from pillows to duvets, bed frames, mattress toppers, and more.
While you may find some of these through other retailers, we'd highly recommend purchasing directly from Emma Sleep.
We've included a quick overview of some of our favourites below.

Emma One delivery conditions
The Emma One can no longer be ordered directly from Emma Sleep, but you can find it on Amazon.
So, what can you expect from Amazon's Emma One delivery services?
Amazon delivery includes:
- Free delivery to your front door.
- Bed-in-a-box design that allows the mattress to be carried more easily.
- A trial period that begins with delivery.
Bed-in-a-box mattresses are very convenient since they allow you to accept a larger mattress delivery and still be able to handle it by yourself. 📦
15% OFF EMMA ONE MATTRESS£ 169.15
All you need to do is unpack the mattress, remove the vacuum seal, and watch your mattress expand.
Off-gassing is very likely with compressed mattresses, but this is simply a side effect of the production process and isn't harmful or toxic.
Most off-gassing usually disappears within a few hours - or a few days at most.

Like other Emma mattresses, the Emma One also features a risk-free trial period and a 10-year guarantee, allowing you to test the mattress in the comfort of your home.
15% OFF EMMA ONE MATTRESS£ 169.15
The warranty covers manufacturing, material, or durability faults.
However, some customers found it challenging to return their Amazon Emma One under these promised trials and guarantees.
Is the Emma One a good mattress?
The Emma One is a high-quality mattress that offers exceptional comfort and support.
If you're still sleeping on one, you're in luck! 🍀
And if you can get your hands on one, we'd recommend it to anyone looking for an affordable, comfortable, and softer sleep.
