Ecosa Vs Emma – NZ Mattress In A Box Comparisons

Ecosa Vs Emma – NZ Mattress in a box comparisons. In this Ecosa Vs Emma showdown, I compare the biggest international brand in our New Zealand market (Ecosa) with the newest mattress in a box to hit our shores (Emma – a hugely popular brand in the UK and Australia). Both are mattresses in a box with a firm feel, but that’s about where the similarities end: these mattresses are quite different to each other, and they feel very different to lie on. If you’re looking for a firm mattress in a box, you’ll want to read this comparison to make the right choice for your needs.

Spoiler alert: my favourite of these two is Emma. Get more Emma details here.

All your questions are answered here, along with detailed comparisons of their construction, prices, and feel. Here’s a general overview to get started:

There are some similarities between Ecosa and Emma, but they’re fewer than you might expect:

  • Both are around 25cm high
  • I rate both as “firm”
  • Both contain three foam layers (totally different construction though, see below)
  • Similar price points (Emma is slightly cheaper)
  • Both are overseas owned companies, making their mattresses off-shore
  • Both offer a 100 night sleep trial and a 10 year warranty


There are more differences than similarities. Despite the fact that in my opinion these are both about the same firmness and feature a 3 layer foam construction, there’s a lot going on here to separate the mattresses. Here’s how:

  • Ecosa is Australian owned, Emma is German owned
  • Ecosa is made in China, Emma is made in Germany
  • Ecosa has a “flat” feel while Emma has a “bouncy” feel (in fact, Emma is the bounciest of all the mattress in a box brands I have experienced)
  • Ecosa has interchangeable layers inside it’s mattress to adjust the firmness (but they’re all pretty firm no matter what you do). Emma comes in one configuration and the foam composition is totally different (more details below)
  • Ecosa has two removable covers. As well as the breathable knit outer, there’s also a waterproof inner cover
  • Emma has the easier care cover, with the handy zip that allows you to remove the top portion of the cover on its own

Close-Up On Their Construction


Ecosa Vs Napp - Ecosa Cross Section

Ecosa is a 25 cm high mattress with 3 internal layers. This is pretty much standard across many mattresses in boxes,both here and internationally. One of the things that really drew us to the Ecosa mattress when we were deciding what to purchase was the fact that you can adjust the firmness level by changing around the layers inside the mattress. This clever design allows Ecosa to make just the one mattress to suit different people. However, even with the softer layer at the top it’s still pretty firm.


As mentioned earlier, Ecosa has two covers on their mattress. Ecosa might be the only brand I’ve researched (both here at home and internationally) that has this.

  1. Removable outer cover made of breathable stretch knit
  2. The removable, waterproof and dust mite repelling inner cover (also removable so you can switch the mattress layers around as desired)

Foam Layers:

The first two layers are your comfort foams.The third layer is the support core layer. You can switch around all of the layers and have any one of them at the top of the mattress as your sleep surface. Again, Ecosa is the only mattress I’ve seen with this adjustable design.

  1. The blue layer is named “G-7”, and is a gel memory foam. Gel memory foam is known for its cooling properties. This layer is 3cm thick. Keep this layer on the top of the mattress for the “softest” feel this mattress can give you (remember, it’s not soft! It’s still very firm to me!). This is how we have our own Ecosa mattress configured.
  2. The white layer is a memory foam that Ecosa have designed themselves. Called Eco-Tex, this open cell foam is designed to mimic the feel of latex (which is known for it’s cooling, durability, and bounce). This layer is 4cm thick, which means the two comfort layers combined make up 7cm of the 25cm total. Put the white layer on the top of your mattress to give it an even firmer feel!
  3. The largest section of the mattress is the high density support foam, made from plant based polyurethane. It makes up about 18cm of the mattress height. This layer is what you would put at the top of the mattress if you wanted it to feel like a rock. Ecosa is actually the first company I’ve seen suggesting you sleep directly on this polyfoam layer, but the airflow convolutions make it feasible.  The convolutions will also allow further contouring support. (If you want this layer on top, you can’t just flip your Ecosa, you need the convolutions facing up to get the airflow benefits)


The Emma mattress is also 25cm high mattress with 3 foam layers, which are OEKO-TEX certified as you read through the descriptions of the foams, the differences with Ecosa will quickly reveal themselves. Here’s what the inside of the Emma mattress looks like compared to the marketing image.

Emma Mattress NZ Cross Section


This is a pretty standard stretch knit with a softer top and grippy material on the bottom to help it stay fixed to your base. The cool feature of the cover is that the zip enables you to unzip the top part of the cover right off. This is extremely handy for cleaning! You don’t have to remove the whole cover. I’ve only seen this on Tempur mattresses here in NZ. The other standout feature of the cover is that it has handles. They feel a bit flimsy, but Emma is the only mattress in a box brand that has them in NZ.

Foam Layers:

  1. The top layer is 3cm of breathable eco friendly foam. This is the softer, memory foam layer of Emma. How’s it breathable? It’s an open cell foam for better air flow. How’s it eco friendly? Memory foams are typically made using fossil fuels. Lately there’s been a move towards using plant based oils instead: Emma uses castor oil to partially replace the fossil fuels in this layer of the mattress.
  2. The middle layer is 15cm pressure relieving 7 zone support foam. This foam is a high resilience polyfoam. You can see from the image that it has zones built into it: these have been carefully placed to help support your shoulders, spine, and legs. This foam layer feels extremely durable and has little “give”. Emma is the only mattress in our current market to feature such a thick high resiliency foam as its main layer.
  3. The bottom layer is 7cm of supportive point elastic foam. This is a high density polyfoam layer. It’s there to provide a solid base that allows the zoned foam and the memory foam above to do their work of giving you the right support. Basically, the top two layers support you, and in turn this bottom layer supports the upper foams!

Feel And Firmness

Ecosa Vs Emma Mattress In A Box NZ Comparison - KettlebellAs I’ve mentioned earlier in the article, these are both firm mattresses but they have a different feel.

Ecosa feels more “flat” to me, while Emma has a bit more contouring through the top as you can see in the kettle bell image. This is because the very top layer of Emma is softer, but the firm, high resiliency zoned foam supports it firmly.

So, if you want bit of bounce and a bit more contouring, choose Emma. If you want flatter feeling mattress, choose Ecosa.

I think both of these mattresses are great choices for stomach sleepers (you need a firm mattress), or for back sleepers who want a firmer feel.

Remember, whichever one you choose, you’ve got more than 3 months to try it out at home.

So – Which Is Better?

I don’t think one is better  than the other. They are just different!

Ecosa’s big selling point is that you can change around the internal layers of the mattress to adjust the firmness level but after owning and sleeping on an Ecosa for a year and a half myself, I think that it’s pretty firm no matter what way you set it up. If you’re looking for a really firm mattress, choose Ecosa.

Emma’s big selling points are the features of the cover, it’s bouncier feel, and focus on zoning.
