The Emma is a 25 cm mattress made from layers of foam and coils.

  • Top layer (comfort) – 4 cm of responsive poly foam. This top layer of responsive poly foam is designed to provide the pressure relief, bounce, cooling, and responsive feel. Responsive poly foams act similar to latex foams in many respects.
  • 2nd layer (support) – 2 cm of microcoils. By placing a layer of microcoils below the top layer of responsive poly foam, the coils are able to assist in cooling, support, and pressure relief. The coils work to relieve pressure, add a little more bounce and breathability, and provide additional softness to the sleeper.
  • 3rd layer (contour) – 3 cm of memory foam. Although this layer of memory foam is placed closer to the bottom of the mattress, it is still designed to offer a level of contour in addition to acting as the softer transition layer from the coils into the base foam.
  • Bottom layer (foundation) – 16 cm of support foam. This layer acts as the deep compression support for the mattress as well as a foundational supportive base.

The cover of the Emma mattress is built from 100% polyester. Additionally, the cover is thin by design. By combining a thin design with 100% polyester, the foams below are able to breathe much easier. The thinner cover also allows sleepers to engage more directly with the foam layers below.

Aesthetically speaking, the Emma uses what I would call the “staple” design for its cover. Many online mattress companies have adopted this gray-and-white color scheme also used by Emma. Although this cover is fairly basic, Emma did a fine job of ensuring clean stitching and a tight fit all the way around the mattress.

Firmness, Feel, & Support

The Emma mattress offers a medium-firm feel, landing at a 6 out of 10 on the firmness scale, where 10 is the most firm. Emma’s medium-firm design was created with hopes of reaching a vast majority of sleepers’ needs as a “universal comfort” mattress.

To begin with, the Emma offers a well-balanced feel. By combining the use of poly foam and microcoils in the top two layers of this mattress, the Emma is able to offer a nice degree of sinkage with a balanced level of push back. As I first lay down on the mattress, I was able to sink in about 5 cm. Yet, the sinkage was not overly enveloping.

Not once did I feel as if I was stuck or trapped in the mattress. In addition to this balanced level of sinkage came consistent pressure relief. With three layers of comfort foam, the Emma was able to relieve pressure in virtually every position. Even as a lighter sleeper (10 stones), this mattress did a nice job of adapting to my weight and providing both pressure relief and support.

Next in line, support. Once again, the responsive poly foam and microcoils created sufficient support, although I did feel as if the mattress wanted to contour a bit too much whilst sleeping on my stomach. However, there were no issues whilst sleeping on my back or side. The Emma’s quick response time and stronger push back helped to create a supportive feel overall.

Spinal alignment was consistent on my back and sides. That said, this mattress is only designed to support sleepers up to 130kg (about 20.5 stones). Sleepers much over this weight could run into support issues.

Bounce and motion transfer were two more areas I wanted to touch on. As expected, the Emma has an enjoyable level of bounce. Again, the combination of materials used helped to provide this higher level of bounce. I would not place it in the same category as a hybrid or spring mattress, but the Emma certainly has more bounce than most foam mattresses. In my opinion, bounce is one of the most impressive characteristics about the Emma mattress. This can be a major plus for those engaging in amorous activities, as well as sleepers who prefer a bit more of a traditional feel.

With this level of bounce does come some motion transfer. That said, the motion transfer was slightly better than I expected. As a hybrid mattress, I was expecting to see a good amount of energy transferred across the mattress. Yet, the Emma’s build does a nice job of absorbing energy and displacing it throughout the layers below. The memory foam third layer plays a  role in dissipating the motion whilst the top layers of poly foam and microcoils provide the sleeper with an above-average level of bounce.

Last but not least, cooling. The thin cover and hybrid construction create a breathable mattress and cooler sleeping surface. Both microcoils and poly foam breathe well, and by adding a thin cover into the mix, the Emma does a fine job of avoiding a warm sleeping environment.

Sinkage Tests

All mattress reviews on Sleepopolis involve a short series of sinkage tests. These tests are designed to provide you with insight into how the mattress responds to various positions.

  • Lying on your back – As I lay down normally on my back with my weight spread evenly across the mattress, I saw 5 cm of sinkage.
  • Lying on your side – As I rolled over to my side, I saw 7.5 cm of sinkage.
  • Sitting on edge (conservative) – In a normal sitting position with my bottom slightly farther back on the mattress, I saw 10 cm of sinkage.
  • Sitting on edge (aggressive) – As I sat more on the direct edge of the mattress, I saw 11.5 cm of sinkage.
  • Standing in the middle – With all of my weight placed at one point in the middle of the mattress, I saw 12.5 cm of sinkage.

Please bear in mind that sinkage results will vary depending on your body type and weight. For the sake of reference, I weigh 10 stones.

Who should buy the Emma mattress?

All things considered, I’m a fan of the Emma mattress. The responsive nature, balanced feel, good support, and breathable design all come together to create a very nice mattress.

I would recommend the Emma mattress to sleepers who:

  • Want a medium-firm mattress – At a 6 out of 10 on the firmness scale, where 10 is the most firm, the Emma mattress offers a medium to medium-firm feel. This mattress was designed as a “universal comfort” mattress with the intention of meeting a wider array of sleepers’ needs.
  • Like the idea of a responsive mattress – Thanks to the combination of a responsive poly foam with microcoils, this mattress has a fairly quick response time. Emma does a nice job of responding to pressure anywhere on the mattress.
  • Want a cooler mattress – Once again, the combination of materials used in the Emma creates a cooler sleeping environment. The poly foam, microcoils, and thin cover all come together for consistent airflow in and out of the mattress creating a higher level of breathability.
