Emma One mattress composition

The Emma One is a foam mattress with three layers and a removable cover.

These layers are:

  • A comfort layer of breathable Airgocell foam.
  • 7-zoned pressure-relieving and cushioning viscoelastic memory foam.
  • Supportive reflex foam.

The layers of the Emma One foam mattress work together to provide comfort and support.

Let's take a closer look at each of these layers and the role they play in the Emma One mattress. 👇

1. Airgocell foam layer

Emma Sleep's unique Airgocell technology provides superior temperature regulation. 🌡️

It counteracts the heat retention properties of memory foam by letting excess heat escape.

It also offers excellent point elasticity, which is particularly important for side sleepers as it allows one area to be compressed without compacting the rest of the mattress.

This layer enhances orthopaedic support and motion isolation features. 👩‍❤️‍👨

2. Memory foam layer

Like all Emma mattresses, the memory foam used is high-quality and high-density.

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. 👇

benefits of memory foam
The Emma One comes with all the standard benefits of memory foam.

Memory foam mattresses are an excellent choice for anyone looking for orthopaedic support.

3. Supportive foam base layer

The majority of the Emma One mattress is made up of a firmer foam layer.

This section provides more support and stability. 💪

It also helps enhance the mattress's durability, which is particularly important given that the mattress is about 7 cm (2.7 inches) thinner than most quality mattresses.

Within the high-density base foam layer, you can see channels called contour zones.

Emma One ventilation channels
Ventilation channels help keep the mattress cool and enhance spinal alignment.

These ventilation channels improve air circulation. 🌬️

More airflow prevents the build-up of mites and bacteria, which prefer warmer and more humid environments.

But that's not all; the channels also act as contour zones and allow for more sinkage in some areas and less in others.

The zones help promote better spinal alignment and a more comfortable night's sleep. 🩻


Emma One mattress cover

The Emma One mattress cover is fully removable and can be machine-washed at 40°C. 🛀

Machine washable Emma One mattress cover
If your Emma One mattress cover gets dirty, you can simply take it off and pop it in the washing machine.

This easy-clean design makes it an excellent choice for people prone to allergies and general hygiene.

The cover is also breathable and moisture-wicking, helping to remove moisture and enhancing air circulation, perfect for warm sleepers. ❄️

Conveniently, the Emma One mattress cover also features 4 robust side handles that make transporting or turning your mattress easier.

Emma One mattress cover handles
While you can't flip the Emma One mattress over, you can use the handles to rotate the mattress to prevent dents from forming.

It should be noted that while the Emma One mattress cover is washable, it is not waterproof.

To avoid stains from accidental spills or sweating, 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. ⏳

Our favourite mattress protectors in the UK:

How firm is the Emma One mattress?

The Amazon Emma One is described as having a medium mattress firmness.

However, many Amazon Emma One reviews state it felt softer than they expected so it seems to be more of a soft-medium mattress. 🐑

We suggest that it sits around a 6 out of 10 on the Sleep Hero firmness scale, where 1 is the softest and 10 is the firmest.

Different degrees of firmness
The Emma One sits on the softer end of medium firmness.

This soft feel differs significantly from the previous Emma One firm foam mattress, which had an 8 out of 10 firmness, according to testers in our original Emma One mattress review.

The current version of the Emma One is best suited to lighter or average-weight people.


Larger individuals will likely find they sink too far into the mattress since it has a soft-medium firmness and is only 18 cm (7 inches) thick. 😬

The firmer Simba Essential mattress, which has a similar depth to the Emma One, measuring 20 cm (7.9 inches), offers a more supportive feel for heavier people despite its slim design.

Alternatively, the Emma Original is a good option if you want a thicker (25 cm/9.8 inches) mattress with similar a soft-medium feel to the Emma One.

Attention stomach sleepers: You'll need a firm mattress to prevent a hollow back and misaligned spine! Check out our favourite mattresses for stomach sleepers here.

How comfortable is the Emma One?

The Emma One mattress is very comfortable.

Many customers comment on the body-hugging feel of the mattress and praise that it doesn't sleep too hot. 💗

Of course, not everyone loves the Emma One, with some noting it feels thin, likely because of its low height and softer feel.

In contrast, a low-height mattress like the Simba Essential doesn't feel thin because it has a firmer feel, which means you don't sink far into the foams at all.

Who is the Emma One most suitable for?

Mattress comfort is influenced by factors like sleeping position, weight, and firmness preference. 🤔

If you want a softer mattress that moulds around your body, the Emma One could be a match made in heaven.

The soft-medium mattress is most comfortable for lighter side sleepers.

Side sleeper spinal alignment
The soft-medium Emma One allows the shoulders and hips to sink in, ensuring optimal spinal alignment.

It would also be comfortable for back sleepers of light to average weights.


Heavier individuals or stomach sleepers should avoid the Emma One as they require a firmer mattress to keep their spine aligned for pain-free sleep. 🧱

Does the Emma One sleep hot?

Memory foam mattresses tend to retain heat, meaning they sleep warmer and will keep you toasty throughout the night.

While the Emma One is an all-foam mattress, most customers say it doesn't sleep too hot. 🔥

This is because the Emma One counteracts heat retention properties with several design features.

These include:

  • A moisture-wicking cover which helps to keep the surface cool and dry.
  • The top layer of Airgocell foam which regulates temperature by distributing heat evenly.
  • Ventilation channels in the base foam layer which promote airflow and reduce heat build-up.

If you're not a particularly hot sleeper, the Emma One will offer a perfectly cool and comfortable night's sleep. ❄️


That said, if you're a very hot sleeper or heavy sweater, we'd recommend you steer clear of memory foam mattresses.

Overheating can reduce sleep quality. 😴

Studies suggest a lower body temperature helps induce sleep [1] and advise that items like mattresses and bedding can help people reach the ideal temperature for sleep.

Airflow through mattress springs
Spring mattresses allow air to circulate, preventing heat retention for a more comfortable sleeping temperature.

Hot sleepers fare much better on pocket-sprung or hybrid mattresses since 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 great mattress for couples. 👩‍❤️‍👨

Its memory foam layer limits motion transfer, meaning you won't feel your partner move at night.

The Emma One is also suitable if you don't love being too enveloped by your mattress because the top layer of Airgocell foam balances out the body-hugging feel of memory foam, making it easy to change positions.

Limited motion transfer
Memory foam mattresses absorb motion, so you won't be bounced around if your partner tosses and turns.

It's relevant to highlight that the Emma One is most suitable for lighter-weight and average-weight people.

If you or your partner are larger or heavier, you'll be more comfortable on a thicker and firmer mattress like the DreamCloud Luxury Hybrid. 🤗

Couples looking for the best mattress must also consider mattress size.

Couples sleeping on mattress
Having a large enough mattress will ensure you get the best night's sleep.

The Emma One is available in a range of sizes, and we'd recommend couples opt for a double, king-size or super-king-size mattress. 👑

A larger mattress ensures you'll have plenty of room for a better night's sleep.


How does the Emma One compare to the other Emma mattresses?

Emma has lots of great mattresses, which can make choosing one tricky.

Here's a quick overview of some of the most popular Emma mattresses compared to the Emma One:

Emma One mattress sizes

The Emma One mattress is available in 5 different sizes.

These include:

  • Emma One single mattress: 90 x 190 cm (3’ x 6’3”)
  • Emma One small double mattress: 120 x 190 cm (4' x 6’3”)
  • Emma One double mattress: 135 x 190 cm (4’6” x 6’3”)
  • Emma One king mattress: 150 x 200 cm (5’ x 6’6”)
  • Emma One super king mattress: 180 x 200 cm (6’ x 6’6”)

Emma One single mattresses or small double mattresses are best if you're short on space and sleeping alone.

Mattress sizes
It's important you choose a mattress that's large enough to let you (and your partner) sleep comfortably.

If you're sleeping with a partner, you'll want to opt for an Emma One double mattress, king mattress, or super king mattress. 👫

No matter the size, all Emma One mattresses are 18 cm (7 inches) deep.


How much does the Emma One mattress cost?

The Emma One is one of Emma Sleep's cheapest mattresses.

While it uses high-quality materials, the Emma One is thin, measuring only 18 cm (7 inches).

We do not recommend thin mattresses for long-term use. 🙅

Several customers seem to agree with this thought, with multiple Emma One mattress reviews pointing to it as a great, affordable option for children or a spare room.

It's also harder to find good discounts on the Emma One now.

Since it's no longer available on the Emma Sleep UK website, you'll miss out on most direct Emma sales.

Luckily, discounted or not, the Emma One is still a highly affordable mattress.

What else does Emma sell?

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 for the best prices, trials, and guarantees.

We've included a quick overview of some of our favourites below.

Emma One delivery conditions

Emma One mattress delivery conditions will change depending on where you shop.

Most UK retailers offer free UK delivery. 🚚

Amazon typically dispatches the mattress within 2 days of the order, meaning you should receive your Emma One 3 to 5 days after purchasing it.

Mattress Online and Mattress Next Day, both of which sell the Emma One, go a step further and provide free next-day delivery.

They also offer additional services like room-of-choice delivery and old mattress collection at an extra cost.

Emma One mattress delivered in a compact box
The Emma One mattress is delivered rolled up in a compact box.

Regardless of the retailer, the Emma One is delivered as a bed-in-a-box, making it convenient to receive and move into your home. 📦

All you need to do is unpack the mattress, remove the vacuum seal, and watch it expand!

You can expect some off-gassing upon unpacking your Emma One mattress.

off-gassing with mattress
Off-gassing is common with compressed mattresses, but the chemical smell usually disappears quite quickly.

The odour from this off-gassing is a result of the manufacturing process and is neither harmful nor toxic.

Typically, any smell will dissipate within a few hours to a day, though a handful of Emma One mattress reviews mention the smell taking longer to disappear.


Emma One mattress trial and guarantee

While Emma Sleep no longer officially sells the Emma One foam mattress in the UK, you can still find it with Amazon, Mattress Online, and Mattress Next Day.

Amazon offers the same 200-night trial as Emma Sleep.

On the other hand, Mattress Online and Mattress Next Day only provide a 60- or 100-night trial, respectively.

Each of these retailers honours the Emma Sleep 10-year guarantee. 📜


However, while Amazon offers the same Emma trial and guarantee, some people still struggle to get their money back.

On analysing Amazon Emma One mattress reviews, we found some customers had challenges utilising the trial or guarantee, instead getting caught between Amazon and Emma customer services. 😣

Woman frustrated and confused
Returning a mattress under the Emma trial or guarantee on Amazon can be a frustrating process.

We suggest buying directly from brands instead of going through other retailers.

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 with a similar feel to the Emma One and want to buy direct from a brand, we suggest checking out the all-foam Emma Original or Nectar Memory Foam mattress.

Should you buy the Emma One mattress?

The Emma One is an affordable, soft-medium, high-quality mattress.

It offers exceptional comfort and support.

We'd recommend it to light to average-weight sleepers who prefer to sleep on their sides and backs. 🛌

While retailers like Amazon honour the standard Emma 200-night trial and 10-year guarantee, some people have experienced issues returning their Emma One.

For total peace of mind, check out our favourite mattress alternatives, sold directly by brands.

Frequently asked questions

  • Was the Emma One mattress discontinued?

    Luckily, the Emma One has not been completely discontinued.

    While it is no longer sold on the Emma Sleep UK website, the Emma One can still be found on Amazon, Mattress Online, and Mattress Next Day.

    It's worth noting that this mattress is not the same as the original Emma One firm foam mattress.

    The current model is noticeably softer and slimmer, with a medium-firm feel and depth of 18 cm (7 inches), compared to the previous Emma One firm foam mattress, which was 25 cm (9.8 inches) thick.

    It's possible that other retailers will stop selling the Emma One mattress UK in the future, given that it is no longer sold directly by Emma Sleep UK.

    Emma Sleep frequently updates its products, and we've seen the Emma One, Emma Premium (replaced by the Emma NextGen Premium), and Emma Cot discontinued in recent years.

    But the Emma One memory foam mattress may also return to the Emma Sleep range, making a similar comeback to the Emma Hybrid.

  • I bought an Emma One before it was discontinued. Has my guarantee expired?

    If you bought an Emma One mattress from Emma Sleep before the mattress was discontinued, there's no need to fear.

    Your 10-year warranty will still be valid.

    So, you'll still be covered if you notice any issues with your Emma One memory foam mattress.

    To contact Emma Sleep about warranty concerns, please e-mail them at support@emma-mattress.co.uk, visit their live online chat, or complete their online contact form

  • Where can I buy the Emma One mattress?

    Emma Sleep no longer officially sells the Emma One foam mattress in the UK.

    However, you can still buy a version of the Emma One on Amazon, Mattress Online, or Mattress Next Day.

    Conveniently, the Emma One mattress UK purchased via Amazon comes with a 200-day trial period and a 10-year guarantee.

    It's worth noting that the Amazon Emma One mattress is only 18 cm (7 inches) tall, which is relatively thin for a mattress and is best for short-term use.

    We'd suggest looking at similar, high-quality alternatives (like the Emma Original or Nectar Memory Foam Mattress) if you want to invest in a longer-lasting mattress.

  • Can you tell me more about Emma Sleep?

    Emma Sleep is a leading bed-in-a-box mattress manufacturer that was first established in Germany in 2015.

    The company's founder, Max Laarmann, initially wanted to produce a reasonably priced mattress that was available online and came with a risk-free trial period.

    Today, the Emma product range has expanded beyond mattresses, and the company operates all over Europe, the UK, the USA, Australia, and more.
