Mattress Construction

Materials Overview
Take your sleep to the next level with the Emma Diamond Hybrid. The Emma Diamond Hybrid Mattress consists of four different layers:
  • Climate-Regulating and Elastic Cover
  • Diamond Degree® Graphite Foam
  • Adaptive Comfort Foam
  • Pocket Springs
  • HRX Foam.
As the most premium mattress in a box in Australia, the Ergoflex™ 5G comprises of the following layers:
  • Luxurious Tencel® Cover
  • Protective Inner Cover
  • 9cm High Density Visco-Elastic Memory Foam (Density: 85kg/m³)
  • 5cm Cool-Sleep Foam
  • 9cm High-Resilience Foam Base.
Comfort Info
The excellent cooling and heat dissipation properties of the Diamond Hybrid mattress helps your body maintain the ideal sleeping temperature, enabling you to sleep longer in the deep sleep phase and feel more well rested when waking up.
Ergoflex is comparable only to TEMPUR®, yet it is technically more advanced and superior in performance to every alternative both in this price range and beyond. As a result it is renowned for delivering deep restorative sleep. The OEKO-TEX® Standard 100 certification makes it a great option for asthma and allergy sufferers as the mattress is resilient to the growth of bacteria, moulds, mildew and fungi. Class-leading zero disturbance technology promotes deeper, more restful sleep as it reduces the likelihood of being woken by a restless sleeping partner. Just watch the video above to see how little disturbance is caused by a parachuter landing on the mattress (spoiler: the wine glass doesn't even fall over!)
Support Info
A hybrid mattress without compromise: the Diamond Hybrid mattress completely moulds to your body, thanks to its adaptive comfort foam and pocket spring construction.
The Ergoflex 5G mattress is the only true high density memory foam mattress available. Designed to mould itself to the contours of your body it provides instant comfort, more support and orthopaedic pressure-relief. It is recommended by Practioners for those that suffer from back pain, fibromyalgia, circulation problems and joint complaints or to those simply in need of a good night's sleep.
Comfort Specs
Diamond Degree® Graphite Foam
This foam layer has an infusion of diamond and graphite particles, this innovative coating quickly dissipates excess heat away; extending the duration of your deep sleep phase. Pocket Springs
Hundreds of individually encased steel pocket springs ensures superb ventilation by allowing air to circulate.
High Density Visco-Elastic Memory Foam
The foam design has billions of ball-shaped open cells that give added breathability than traditional memory foams which have been known to sleep hot. Cool-Sleep Foam
This unique Cool-Sleep airflow system encourages air to freely circulate thorough the mattress keeping you cool while you sleep. It does this by using a specially-engineered foam design that instead of being a rectangular block of foam it more resembles an upside down egg carton, which has channels for temperature-regulation. These work in combination with the 3D mesh panels in the outer cover to disperse heat.
Support Specs
Diamond Degree® Graphite Foam
The low rolling-resistance of the Diamond Degree® graphite foam requires less effort from your body when you involuntarily toss and turn during sleep, meaning you're less likely to wake yourself up or be disturbed by your partner in the middle of the night. Adaptive Comfort Foam
The ergonomically designed adaptive comfort foam layer adapts to your body and optimally distributes body pressure, allowing you to sleep comfortably regardless of your build or sleeping position (back, side, stomach). Pocket Springs
Individually encased steel pocket springs provide dynamic body adaptation, while also allowing for movement isolation to minimise disturbances brought about by movements. HRX Foam
The supportive HRX foam layer provides optimal back support thanks to incisions in the foam and gives superb durability.
High Density Visco-Elastic Memory Foam
This comfort layer gives the optimum level of support, shifting responsively to your movements. You will experience a feeling of pure weightlessness as every part of your body is supported and cradled which alleviates pressure points (such as your hips, back, and shoulders). High-Resilience Foam Base
This base layer provides the precise support for the upper foam layers and gives the mattress its performance longevity. Ergoflex mattresses stand up to their warranty claims - Ergoflex's ten-year guarantee is underpinned with the confidence of having had more than a decade of success and continuing.
Fabric Specs
Climate-Regulating and Elastic Cover
This fully breathable, removable, and washable premium cover is designed to help facilitate heat dissipation of the Diamond Degree graphite foam. Its airy structure lets the mattress breathe during the day without hindering the thermoregulatory effects of the mattress. The top of the cover is made of 99% polyester and 1% elastane. The bottom cover has convenient handles and is made of 87% polyester and 13% polypropylene, and the sides are made of 100% of polyester.
Luxurious Tencel® Cover
This Tencel® outer cover provides a natural, antibacterial and breathable sleep surface. Tencel is sustainable an outperforms natural cotton in terms of moisture-wicking and breathability. It can also be removed and is machine-washable at 30°. The cover also has vented 3D mesh panels at each end to allow heat to escape. Protective Inner Cover
This super fine inner cover protects the core foam layers.
