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.
Our recommended UK mattress alternatives
Emma Sleep no longer sells the Emma One in the UK.
While you can still buy the Emma One on Amazon, we'd highly recommend choosing your new mattress from our best mattress recommendations instead.
We have chosen a few recommendations that are most similar in style and feel to the Emma One foam mattress.
Best Emma One mattress alternatives:
Emma One mattress composition
The Emma One is a foam mattress consisting of three individual layers.
- 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 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.
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.
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:
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.
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. 👍
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.
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. 📦
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.
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.
