An innovative mattress for better sleep

The latest innovation from Emma's research and development team. The deep sleep phase is one of the most important areas in our sleep research. For letting your body fall into a deep sleep, the body temperature must drop. That's the promise of Emma's Black Diamond.

This is how and why the Emma Black Diamond Mattress works.

Perfect body support

A mattress perfectly suits you, thanks to its adaptive comfort foam and its springs: a hybrid mattress without compromise.

Optimized deep sleep

To reach the phase of deep sleep, the body temperature must drop. With this mattress, the ideal temperature is maintained and guarantees you a longer and particularly restful deep sleep.

Revolutionary technology

With the Diamond Degree® innovation, the graphite particles in the top layer of the mattress constantly dissipate excess heat: the ideal sleeping temperature is then reached in record time.

The perfect sleep from A to Z

Thermoregulatory and elastic cover

This fully removable premium cover is designed in such a way that it allows the Diamond Degree graphite foam to best dissipate heat. Its aerial structure lets the mattress breathe during the day while not blocking the thermoregulatory effect specific to the mattress.

Diamond Degree® graphite foam

With diamond dust, this innovation in graphite coating allows an extension of deep sleep phases by dissipation of body heat.

Adaptive comfort foam

This foam distributes the pressure optimally. This technology allows you to sleep comfortably regardless of your position.

Pocket springs

The pocket springs of this mattress provide dynamic body adaptation and improved breathability.

HRX foam

A foam providing optimal body support.
