Emma Diamond Hybrid II Mattress Review

The Australian summer can get really hot so getting a cooling mattress is always a good idea. In this Emma Diamond Hybrid II mattress review, I talk about this updated version of a mattress that has seen great success over the years.

Awarded “Best Cooling Mattress” for 2024

Emma has an extensive mattress range that also includes the new Emma Comfort II mattress. When designing the Diamond II, the target was to create a mattress with advanced cooling properties. For this reason, they have used high-tech materials but more on that later. I decided to get mine two weeks ago so it’s time now to move to the full review below.

What is this mattress made of?

This mattress features 5 layers plus the cover. In detail, these are:

  • A ThermoSync foam layer that is infused with NanoCarbon particles. It can absorb your body heat and redistribute it away from the mattress. This leads to a more comfortable sleep.
  • An Aerofoam layer that can adapt to your body and take the pressure off sensitive areas. This layer is extremely breathable and allows airflow.
  • A MemoryAdapt foam layer that optimizes pressure distribution.
  • A SupportBase foam layer that delivers the right amount of firmness.
  • An Infinity spring layer that can provide your body with extra comfort and support. These are tall springs that allow airflow.

The Diamond Hybrid II mattress measures 27cm in height so you should expect a medium profile. The picture below gives us a better look at how this mattress looks from the inside.

Does this mattress have a nice cover?

This mattress comes with a fantastic cover that is made with UltraDry fabric. It’s extremely breathable and it has the ability to regulate heat. That means that during the summer you will sleep cool which is very important when you live in Australia. The good news is that it’s a removable cover and if you want to clean it, you can use your washing machine.

The design is the typical Emma one so you should expect a grey side part and a white top part. On the sides, you will find 4 handles that make it easier to move when that is needed. Finally, at the bottom, there is an anti-slip base for extra stability. Overall, this is a functional cover that has all the right elements.

Is this a firm mattress?

I want to continue writing this Emma Diamond Hybrid II mattress review and talk about its firmness. This is actually the softest mattress that I have tried and it comes with a medium-soft feel. If I use my virtual scale here, I would say it’s a 4.5 with 10 being really firm. Let’s talk now about my experience with it in the past two weeks.

Lying on my back, the mattress felt soft but I didn’t feel that I was sinking into it. That made it super comfortable but my body was well-supported.

Turning to the side position, my spinal alignment was correct and there was no discomfort in the hip area. This was expected from a medium-soft mattress and I felt very comfortable sleeping this way.

Finally, turning to the stomach position this mattress surprised me. Despite being quite soft, I felt that it supported my hips and shoulders so it wasn’t uncomfortable. As a result, I can say that this is a true all-rounder and it will suit every sleeping position.

For those who share their bed with a partner, the edge support is good thanks to the Infinity springs. That will allow you to use the whole sleeping surface. Additionally, motion transfer is minimal so you won’t disturb each other during sleep.

Will I pay for delivery?

If you order a mattress from Emma, you will get free delivery and you should expect your mattress within 0-7 working days. Of course, if you live in a Metro Area (Sydney, Melbourne, Brisbane and Adelaide) you might be eligible for same-day delivery! All you have to do is place your order before 10 am and you will get it between 2-6 pm. Otherwise, your mattress will be delivered within 1-3 business days. As I have mentioned earlier, the mattress will be packed inside a carton box and you have to let it decompress for a few hours before you can use it.

How can I try it before I buy it?

One of the main reasons that customers don’t want to buy a mattress online is that they cannot try it out. Emma understands that and for this reason, they offer a 100-night trial period that allows you to try it at home. You actually have more than 3 months and if you don’t like it, you can return it and get a full refund. Returns are free and they will arrange everything for you.

Moreover, all Emma mattresses come with a 10-year warranty which is the standard for all these boxed mattresses. That will cover you for a long time but for all the details, you should read the full terms and conditions. Overall, this is a complete package here so no complaints from my side.

How much will I pay for it?

The Diamond Hybrid II mattress is available in 5 sizes so you have plenty of options to choose from. The smaller size (Single) sells for $1,560 while the bigger one (King) goes for $2,510. Having said that, Emma is a brand that runs frequent promotions so you will definitely pay less than the retail price. For instance, at the moment of writing this post, a Queen size mattress was sold for $1,625. The table below has pricing information for all available sizes.

Single188 x 92 x 27cm$1,560
King Single203 x 107 x 27cm$1,710
Double188 x 138 x 27cm$2,160
Queen203 x 153 x 27cm$2,310
King203 x 183 x 27cm$2,510

Should I buy the Emma Diamond II mattress?

I want to complete this Emma Diamond Hybrid II mattress review and share my final thoughts with you. This would be a great option for anyone looking for:

  • A cooling mattress that is very comfortable.
  • A hybrid mattress that is suitable for all sleeping positions.
  • A mattress that comes with a 100-night trial period.

This is a unique mattress as it comes with a medium-soft feel and it’s geared towards sleepers who seek comfort. It also features an excellent cooling mechanism and it’s built with the latest technology. Overall, it’s a nice upgrade from the previous model and it’s a mattress that I can recommend.
