In this Emma Diamond hybrid mattress review, I will talk about this latest release from Emma that is designed for those who sleep hot. After seeing great success with their Emma Luxe Pro mattress, they decided it was time for a more premium mattress.
The Diamond mattress follows a different design approach and it’s the first hybrid mattress from Emma. During the design process, they wanted to create a mattress for the hot Australian weather so they used graphite but we will talk about it later. Mine was delivered about 2 weeks ago so let’s move now to the full review below.

Who is the Emma Diamond mattress suitable for?
- Those looking for an efficient cooling mattress.
- Sleepers who tend to move a lot during the night.
- People who prefer a medium feel.
- Couples that seek a mattress with good edge support.
What is an Emma Diamond Hybrid mattress made of?
The Emma Diamond mattress features 4 layers plus the cover. In detail, these are:
- A graphite foam layer that is designed to stay cool during the night. It also minimizes motion transfer so you and your partner can sleep better.
- A comfort foam layer that can adapt to your body and provide it with the needed pressure relief.
- A pocket-spring layer that will support your body and adjust to its movements. This layer allows airflow so it helps the mattress stay cool during sleep.
- An HRX foam layer that is the base of this mattress. It features a 3-zone system that can provide your body with personalized support.
The mattress measures 25cm in height and the picture below showcases the position of each layer. All foams used to make it follow the OEKO-TEX 100 Standards so they are safe for the human body.
What is the cover made of?
The cover of this mattress is made of polyester. For the top part, they have added 1% elastane to ensure that the fit is great. They used this material for a number of reasons. Firstly, it’s very breathable and that helps the mattress stay cool during the night. Secondly, it’s easy to maintain and you can wash your cover at 30 degrees using a gentle cycle. Lastly, it feels nice and it’s a material that is very durable. That means your cover can look good for many years.
The design is a beautiful one and it features a dual-tone colourway. The upper part is white and the bottom part is grey. The people at Emma also added green details and 4 handles that can help you move the mattress whenever needed. Overall, this is a great cover and that is something I expected from a maker like Emma.
How does the Emma Diamond mattress feel?
When designing it, the people at Emma wanted to create a mattress that would suit most people. For this reason, the Emma Diamond mattress comes with a medium feel. If I use my virtual scale here, I would say it’s a 5.5 with 10 being really firm. That makes it slightly firmer when compared to the Emma Comfort II mattress. Let’s talk now about the different sleeping positions and how this mattress performed.
Starting from the back position, the mattress felt comfortable and the upper layers hugged my shoulders. Support was good and the mattress distributed my weight evenly. Pressure relief was great and that is something I needed as I suffer from a bad back.
Turning to the side position, the pocket springs adjusted quickly and sinkage increased. My spine alignment was great and the mattress did a good job in this position. I felt well-supported and I didn’t have any discomfort in the hip area.
Finally, moving to the stomach position, the mattress supported my hips and shoulders and I felt that the feel was right for my body weight. My spine was aligned properly and overall I felt very comfortable sleeping this way. I think that this mattress is a great all-rounder and it will suit most sleepers.
If you share your bed with a partner, the Emma Diamond Hybrid mattress has great edge support so you will get the same performance across the 4 corners of the sleeping surface. In addition, the pocket springs used here are designed to minimise motion transfer so you and your partner won’t disturb each other.
Does this mattress actually sleep cool?
The Diamond mattress was designed with hot sleepers in mind so it sleeps cool. Every single layer in this mattress has cooling properties and the result is an impressive one. The Diamond Degree foam is the key here as it can remove the excess heat which in turn helps you to prolong deep sleep. The UltraDry cover is also doing a great job and the whole cooling mechanism is very efficient. As a result, this is one of the best mattresses of this kind that you can find in Australia.
Do I need a special setup to use this mattress?
When you buy this mattress, you don’t need a special setup so feel free to use your old bed frame. I would advise you to use a slatted frame that allows airflow so your mattress can breathe better. Box springs are also great and if you are looking for a quality one, the Emma Box bed is a great choice. The video below presents the Emma Diamond mattress in great detail.
Is this a boxed mattress?
If you order an Emma Diamond mattress, you will receive it packed in a box. All you have to do is unroll it and let it rest for 24 hours before you are ready to use it. All mattresses come with free delivery which is great! Emma has a good service and I received mine within 5 working days. My experience with them was great and I received good communication. The courier was polite and prompt and overall, I was happy with the service I got.
Does it come with a trial period?
All Emma mattresses come with a 150-night trial period so you have around 5 months to try this mattress and decide later whether you want to keep it or not. If for any reason, you are not happy with it, you can return it and they will give you a full refund. In addition, the mattress comes with a 10-year warranty that will cover you for a really long time. The warranty is offered on the dimensional stability and durability of the core materials. If you want more details on that, you can visit their warranty page. The package offered here is a great one overall, and Emma did a great job here.
How much does it cost?
The Emma Diamond Hybrid mattress is available in 5 sizes so you have a number of options to choose from. The smaller size (Single) goes for $2,499 with the bigger (King) selling for $3,749. However, you won’t have to pay that as the people at Emma run frequent promotions. For example, at the moment of writing, there was a 55% discount so you would pay around $1,600 for a Queen size. The table below has pricing information for all available sizes.
| SIZE | DIMENSIONS | PRICE |
| Single | 92 x 188 x 25cm | $2,499 |
| King Single | 107 x 203 x 25cm | $2,779 |
| Double | 138 x 188 x 25cm | $3,059 |
| Queen | 153 x 203 x 25cm | $3,329 |
| King | 183 x 203 x 25cm | $3,749 |
Is the Emma Diamond Hybrid mattress a good buy?
It’s time now to complete this Emma Diamond Hybrid mattress review and share my final thoughts with you. I think that this mattress is ideal for those looking for:
- A mattress that is good for all sleeping positions.
- A hybrid mattress that sleeps cool.
- A mattress that has excellent support and it’s good for couples.
If you look for all these features, the Emma Diamond should be high on your list. It’s a complete mattress that comes with excellent service and support. Emma managed to develop a fantastic hybrid mattress and this is an option you should definitely consider.
Alternatives to consider
The natural alternative to this mattress is its improved sibling, the Emma Luxe mattress. The engineers at Emma managed to improve an already great mattress and this is hard to ignore. The main difference here is the feel, the Emma Luxe is slightly softer when compared to the older version. Other than that, you should expect more comfort and a slightly better cooling performance. The support package remains the same and the people at Emma didn’t raise the price for the newest version. As a matter of fact, they have even reduced it slightly. Overall, the Emma Luxe is a fantastic choice that will help you sleep cool.
Another great option you should consider is the Onebed X mattress. This is a true all-rounder that is built for any type of sleeper. It has an open-cell foam structure that allows airflow and a viscose blended cover that is very breathable. At the core, the tall pocket springs work as air canals and the mattress has a reliable cooling mechanism. Besides that, you should expect good levels of support and comfort but also great edge support. If you decide to buy one, you will get a 125-night trial, a 15-year warranty and free delivery. In terms of the cost, both mattresses are priced closely so the end decision is down to your preferences and taste.
