How We Test

Our testing process

Corner of the Emma Premium Topper.

In this Emma Premium Topper review, we're going to find out how much of a difference a good mattress topper can make to your sleeping experience!

Mattress toppers are a great solution to improve your old mattress as a temporary fix. Otherwise they can be good for a new mattress that is slightly lacking comfort and/or support. This is the second memory foam topper that Emma has available and it's an upgrade from the Emma Flip Topper. Memory foam toppers are the most common types of topper but does that make it the best mattress topper?

In our Emma mattress topper review we are going to tell you about our experience with the topper and compare it with the Emma Flip Mattress Topper.

Who is the Emma Premium Topper for?

The biggest selling point for the Emma topper is its sleep tech qualities that cool down your body and offer better deep sleep. The Emma topper is also on the thicker side of things (at 9cm – compared to 6cm of the Flip Topper) and highly comfortable too. So, it's perfect for:

What do we use this product for?

The most obvious use for this mattress topper is to combat the stuffiness that comes with an old mattress. The temperature regulation qualities on their own already make the Emma topper a good addition to any sleeping routine.

However, the topper is also thick and comfortable, meaning that it can add some softness to a stiff mattress and even provide pressure relief throughout the night. We can use it for:

Features you should know about the Emma Premium Topper

We've already made a few claims about this mattress topper. Now it's time to dissect what makes it so great and see how all the features meld together to create a premium product.

Premium ThermoSync

Let's start things off with arguably the most impressive aspect of this mattress topper – the top layer of the topper, the graphite layer. Graphite is an excellent thermal regulator, allowing your body heat to quickly and easily disperse through the topper as you sleep. Plus, graphite is hypoallergenic, meaning that you don't have to worry about the graphite particles causing any type of rash or allergic reaction.

This graphite foam layer is what gives the Emma Premium Topper such a competitive edge. Its main purpose is to reduce overheating and to absorb any moisture so your mattress has less chance of sagging. And if you combine this topper with a good hybrid mattress you can rest assured that things will stay cool and comfortable.

Adaptable HRX comfort foam

Although not as flashy as the graphite foam layer, the comfort foam layer is still essential for this topper. The HRX foam allows for your body heat to pass through the topper smoothly and it provides pain and stress relief while you sleep. Because if you want a deeper sleep, not being in pain is a really good place to start.

This foam can be found in the Emma mattresses too so we know it serves a practical use for the performance of the product. It's pressure relieving whilst providing comfort and support.

Plus, the adaptive comfort foam can resolve a lot of discomfort if you have an old mattress that has lost its bounce long ago. So, even the HRX foam is essential to raise your sleep quality.

Diamond Degree Technology cover

As we've seen with the first two layers, a key feature of this topper is its capability to disperse body heat. So, even the covers are made to be extremely breathable.

The Emma Diamond Degree topper cover offers additional plushness and thickness, softness and durability so you can get the extra comfort from the cover too.

And if that wasn't good enough, it's also a removable cover, meaning that getting things clean and fresh is as easy as it gets.

100-night trial and 10-year guarantee

When buying a mattress or a mattress topper, trials and guarantees are always a sight for sore eyes. After all, most mattresses can be deceptive at a single glance. However, with such a generous trial period and a decade-long guarantee, getting Emma toppers doesn't feel like a risk, which most sleepers will be thankful for.

OEKO-TEX Standard 100 certified

This certification means that every part of the mattress topper has been tested for harmful substances. That means that this product is completely safe for adults and children alike.

Plus, it means that the production of the Emma topper was done under sustainable socially responsible conditions – which is always a nice plus to have.

Review of the Emma Premium Topper

Close up of the surface of the Emma Premium Topper.

Overall, this mattress topper has been delightful. It's a bit expensive, but we think that it more than makes up for the price with its premium-level materials and effective design. In terms of temperature regulation, it has had an excellent performance, keeping things nice and cool even when the bed was placed in a stuffy room.

The memory foam offered sufficient support and stress relief.

In our experience, our deep sleep has been positively affected. There were no body aches upon waking up and no discomfort during the night.

Aspects like motion transfer and edge support were a bit more difficult to gauge, as those primarily rely on the mattress rather than the topper. However, when placed on an Emma mattress, things ran smoothly and the edge support was more than sufficient. Needless to say, Emma seems to be offering some premium-level products.

What we like about the Emma Premium Topper


What we didn’t like about the Emma Premium Topper

  • It is a little expensive for a topper. There are cheaper alternatives available if you're looking for a temporary fix.
  • It isn't the most firm foam mattress topper but it is supportive. We would definitely prefer this one if we're looking for a topper that can provide comfort.
  • We didn't like the texture of the cover to begin with as it was initially uncomfortable. However, once you pop a fitted sheet over the top it feels much better.

The common problems with the Emma Premium Topper & how to solve them

The most common problem people might have with the Emma topper is the lack of support. And the best way to solve this problem is to make sure you also have a good mattress underneath. Personally, I'd go for the NextGen hybrid mattress, as hybrid mattresses will keep things nice and cool while also adding some firmness through the box springs. Plus, if you're going for an Emma mattress, there's already a precedent for the level of quality you can expect.

Emma's customer service and company information

Delivery – Free delivery is standard for all your orders and returns are free within the trial period. The delivery time can vary but you can usually expect it to be dispatched in a week, as I experienced.

Payment – They have the usual payment methods, as well as PayPal and DivideBuy where you pay in instalments.

Online customer service – For customer service and any queries, you can send Emma an email or you can have a look through their list of FAQs. If you can’t find what you’re looking for, you can always leave us a comment and we can help you out!

Check the alternatives to the Emma Premium Topper

If the topper doesn't seem to be to your liking, there are always more options out there. If you want a good premium topper from a well-established company, why not go with Simba?

Simba Hybrid Mattress Topper

If you want the same premium quality that the Emma Premium is offering but you're looking for a bit more support and stability, the Simba Hybrid mattress topper could be for you.

The 2500 pocket springs will give you the optimal balance between comfort, firmness & pain relief. Plus, the topper is hypoallergenic so you can sleep without any stress that you might catch an allergy or anything.

With wriggle-free sleep straps to stop the topper from moving around during the night and the renowned triple Simba layer structure, the Simba topper is bound to leave an impression.

What makes this product better than some other similar ones?

What makes the Emma topper a game changer is its intricate layer design. It's built in a way where your body stays cool through the night and allows sleep to come easily. Both the foam and the graphite layers are also very soft, leading to a heightened comfort level as well.

How did we test the product?

Now we're going to explain a bit more about how we actually test our products. On the most fundamental level, all products go through the following inspections:

Inside the Emma Premium Topper.
  • Visual inspection
  • Hands-on inspection
  • Measured tests

With the Emma topper, we wanted to test how well it worked with a variety of different mattresses. Between spring, foam, and hybrid mattresses, old mattresses, and brand new ones, here are the tests we did:

  • Look at the aesthetic of the product
  • Find the key features and see how well they work
  • Trial sleeping position
  • Spend time lying on the mattress topper and comparing alongside others

Is the Emma Premium Topper eco-friendly or sustainable?

Although the Emma topper does sport an OEKO-TEX Standard 100 certification, it doesn't seem to be doing much else in terms of green initiatives:

Aside from this, we were able to find next to nothing about Emma's green initiative. So, they could definitely do a lot better in this field.

Overall impressions of the product after the testing

Overall, the Emma topper was an amazing product as far as we're concerned. When paired with something like the Emma NextGen Mattress, we experienced a great deal of comfort and had no issues with overheating. And even when we didn't put it on the best mattress at hand, the results were satisfactory. Our only issue came about when placing it on a very firm or old mattress, as even the Emma topper can't salvage that situation.

The King size was big enough for all of our mattresses and the foam didn't have any major off-gassing issues. Finally, the cost, although on the more expensive side of things, didn't seem too egregious. Overall, testing went well and the Emma topper gets a golden star from us.
