Materials & Construction

The Emma Diamond Premium mattress offers superior 7-zone dynamic support where your body needs it the most. Its adaptive comfort foam and pocket spring construction allow it to mould completely to your body, providing support like no other mattress. This mattress is guaranteed to provide superior support in all the right places.

  • Diamond Degree® Graphite Foam
  • Adaptive comfort foam
  • Pocket springs
  • HRX foam
  • Hypoallergenic Mattress Cover

Diamond Degree® Graphite Foam – It forms the top comfort layer of the mattress, making it different from other mattresses that use regular memory foam. This exclusive graphite foam layer is designed to optimise body temperatures without causing overcooling, thereby extending deep sleep phases.

Moreover, this layer is infused with diamond and graphite particles, an innovative feature that aids in rapid dissipation of excess body heat, ensuring a cooler and more comfortable sleep. This technology not only enhances the comfort of the mattress but also contributes to a more restful and restorative sleep experience.

Adaptive Comfort HRX Foam – This is a denser foam that goes underneath the top comfort layer. However, it’s ergonomically designed for people of all body types, adapting to your body and optimally distributing the pressure on the mattress. The groves ensure that this technology will keep you comfortable no matter how you sleep.

AeroFlex Pocket Springs – The Dynamic Spring Core, featuring AeroFlex® Pocket Springs, offers dynamic body adaptation and superior breathability. Each pocket spring is individually encased in steel, allowing it to adapt dynamically to body movements. This not only reduces motion transfer through the mattress but also maintains the responsiveness that is highly sought after in a premium mattress. Compared to standard foam mattresses, these pocket springs enhance breathability, contributing to the longevity of your hybrid mattress.

Supportive HRX Foam – This foam prevents the mattress from sagging under the pressure of the upper layers. This base layer is composed of durable HRX polyurethane foam, which offers three zones of support sections for your back while you sleep.

In addition to providing foundational support, this layer delivers superior counter pressure, ensuring a balanced and comfortable sleep experience. This feature enhances the overall functionality and comfort of the mattress, making it an ideal choice for restful sleep.

Hypoallergenic Cover – It's encased in a thermoregulatory and elastic cover, designed to work in harmony with the Diamond Degree graphite foam top layer to dissipate heat. Its aerial structure allows the mattress to breathe during the day without interfering with its thermoregulatory properties.

This cover is not only removable and machine washable, but it also provides a plush touch. Additionally, it features thick handles on the sides for easy manoeuvrability. The cover is constructed with sustainable natural bamboo and viscose, providing a soft, fluffy, and luxurious feel.

Moreover, what makes this cover unique and turns it into one of the best mattresses for allergies is that it’s treated with microfibers and natural probiotics, making it hypoallergenic. It drastically reduces allergens while naturally keeping the surface of your mattress clean and fresh. This feature is a boon for allergy sufferers, promising a carefree and restful sleep by repelling dust, pollen, and other allergens.

Emma Diamond Topper - The topper is a perfect companion to the Diamond Hybrid Premium mattress. The topper is made from Diamond Degree and HRX comfort foam, 100% vegan, non-toxic, and OEKO TEX-100 certified.

It's a great addition to any mattress due to its portability and added comfort. Or it can be a budget-friendly way to improve your existing mattress to get a similar feel. Plus, it comes with a 100-night trial period and a money-back guarantee to try it out risk-free.

What’s it like to sleep on?

The sleeping experience is truly unique. The mattress combines the pressure-relieving effects of graphite and HRX foam, which contour your body, providing a hugging sensation. Despite this, the mattress maintains responsiveness due to the springs beneath, a feature that many sleepers appreciate.

It doesn’t retain heat and sleeps much cooler, making it an ideal choice for hot sleepers. The normal version of this mattress was one of the best mattresses for deep sleep, given the advanced sleep technology incorporated into its design.

Edge support – Thanks to the firmer foam that encases the springs, it excels in edge support. This ensures excellent performance across the entire mattress surface, with no additional dip when you get close to the edge.

Firmness – In terms of firmness, the Emma Diamond Premium Mattress falls in the medium range (6.5/10) due to the thoughtful design and development of the mattress. Foams provide pressure relief while springs and base provide support, resulting in a well-balanced mattress.

Partner disturbance – A key feature of this premium mattress is its excellent motion isolation. During the night, you won't disturb your partner or be disturbed by them. Foam mattresses typically have better motion isolation but lack bounce. This mattress is the best of both worlds.
