Description

Looking to get a more restorative night's sleep? The Emma® Diamond Spring Free Mattress is specifically designed to offer enhanced deep sleep, increasing the length of your most restful sleep stages. Emma's sleep experts and engineers have created technology that helps you to sleep quicker, longer and deeper than before - and all you have to do is lay down.

Extend your deep sleep phases by up to 12%

Using natural heat conductor, graphite, Emma have created their bespoke Diamond Degree® technology. By infusing special foam layers with graphite particles and a graphite coating, your body heat is dissipated, which aids the body's natural process of cooling down to enter a deep sleep. This technology, incredibly, helps to shorten light sleep phases and extend deep sleep phases, helping you reach the latter in record time.

Once you've reached the optimal sleeping temperature, the Emma® Diamond Spring Free Mattress has you in the ideal sleeping conditions. With your body physically relaxed and comfortable, your brain is able to support a deeper, more rejuvinating sleep - the only problem you'll face will be wanting to get up in the morning.

Targeted orthopaedic support with a firm feel

These layers of graphite infused foam not only keep you cool, but also contour to the unique shape of your body. Optimum body support and dynamic adaptation mean you'll recieve firm, orthopaedic support no matter how you turn and move in the night. Your spine will be kept properly aligned, while your posture is maintained and joint pains are eased.

An open-pore sandwich core ensures maximum breathability for the most refreshing night's sleep possible. A zoned HRX™ foam foundation ensures targeted support to your heaviest pressure points - your hips and shoulders - to keep your back in the correct sleeping position.

To further enhance the cooling effect of this mattress, the Emma® Diamond Spring Free is finished with a SensICE® cool-touch cover, which is completely removable and washable up to 40°C.

Amazing mattress. Takes a few days to fully take shape as it is boxed. Right firmness, good height. Side handles for easy manoeuvring. Good nights sleep and knowing a loose spring will not ruin my nights sleep ever!
