Combining the newest, most innovative of Emma's sleep technologies, the Emma® Diamond Hybrid Mattress is specially designed to offer not only unparalleled support and comfort, but also extend your deep sleep phases by up to 12%.

Revolutionary Diamond Degree® technology that keeps you in a deep sleep

The star of this mattress is the incredible Diamond Degree® technology from Emma's expert sleep engineers. Foam infused with graphite particles and a graphite coating dissipate heat, which helps to cool your core body temperature by up to 1.5°C. This encourages your brain to begin producing melatonin, the sleep hormone, which in turn gets you to sleep quicker, and helps you sleep more deeply.

This technology extends your deep sleep phases, while shortening your light sleep phases. You'll experience truly restorative sleep, with sleepers having noted a higher sleep quality within even the first hour of hitting the hay.

The Emma® Diamond Hybrid features a layer of adaptable pocket springs, created to offer optimum body support. With a medium tension, these springs target support and pressure relief to precise areas of your body, reacting to your movements in the night. With the help of a layer of comfort foam with core cut, this support is tailored to your heaviest pressure points, keeping your spine nicely aligned and posture controlled.

Adaptable foam layers that cradle you in comfort, maintaining a medium feel

As well as regulating your temperature, the revolutionary Diamond Degree® graphite foam also contours to your body, cradling you in comfort that also adapts to your movements. Springing back to shape once pressure is removed, you'll experience personalised support every single night.

Finished with a SenseICE® cool-touch cover, this mattress maximises breathability and cleanliness. Completely removable and machine washable, this cover helps you keep your bed as hygienic as possible.
