Features you should know about the Emma Diamond Degree mattress 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 in order to create a premium product.
Diamond Degree Technology
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 into the lower layer of the topper as you sleep.
This graphite foam layer is what gives the Emma Diamond topper such a competitive edge. Plus, graphite is hypoallergenic, meaning that you don't have to worry about the graphite particles causing any type of rash or allergic reaction.
And if you combine this topper with a good hybrid mattress you can rest assured that things will stay cool and comfortable. And don't worry, if you want to know what hybrid mattress is the very best, just check out our guide.
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.
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 in order to raise your sleep quality.
Breathable and elastic 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.
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. And as the “100” would suggest, Emma passed with flying colours. 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 Diamond Degree 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. And in our experience, our deep sleep has in fact 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 Hybrid, things ran smoothly and the edge support was more than sufficient. Needless to say, Emma seems to be offering some premium-level products.

The common problems with the Emma Diamond Degree 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 Diamond 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 the Emma hybrid, there's already a precedent for the level of quality you can expect.

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:
- 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 over the course of multiple days. Between spring, foam, and hybrid mattresses, old mattresses, and brand new ones, here are the tests we did:
- Leaving a heavy object on one part of the Emma topper to see whether it would develop lumps
- Staining and washing the Emma topper to see whether there'd be any noticeable damage
- Have multiple team members sleep on the Emma topper to check the comfort and motion transfer throughout the night
- Perform a roller test to see if the fabric can withstand abrasion and prolonged use.
Is the Emma Diamond Degree mattress 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:
- The substances used in production are all safe
- The production is done within the UK, leading to a lesser carbon footprint
- Polyester is used frequently, which is non-biodegradable.
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 Diamond Hybrid 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.
