Firmness Info
The Ergoflex mattress is a result of over a decade of research and development. This one 'perfect' mattress is rated medium-firm and is optimised with the highest-quality materials available, and has thousands of 5-star reviews from customers in Australia, the UK, and all over the globe.
The Onebed X has a feel that will be perfect for the vast majority. It gradually transitions from a firmer supportive base to softer comfort layers for that ultimate feeling of comfort and support.

Mattress Construction

Materials Overview
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.
The Onebed X is the latest hybrid to hit the Australian market, combining all the best features of different mattress types into one, for the ultimate choice in luxury mattresses. It is a five-layer hybrid construction:
  • Viscose Blended Cover
  • Davina Foam
  • Gel-Infused Memory Foam
  • Charcoal Memory Foam
  • 5-Zoned Pocket Springs
  • High-Density Base Foam.
Comfort Info
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!)
The open-cell foam structure, airy pocket springs, infused cooling gel and highly breathable fabric keep the Onebed X refreshingly cool and comfortable, all night, every night. The Onebed X also isolates motion with paramount precision, passing the wine glass test with ease, so you stay deep in a state of deep sleep even if your sleeping partner is tossing and turning.
Support Info
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.
The Onebed X gives you the optimal balance between comfort and support thanks to softer memory foam layers, the zoned pocket springs, and firm base foam.
Comfort Specs
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.
Davina Foam
This breathable foam, used in the comfort layer, is extremely bouyant and helps with motion-isolation. Gel-Infused Memory Foam
The gel infusion helps keep you cooler. Charcoal Memory Foam
Charcoal eliminates odours, absorbs moisture and helps regulate temperature. Making it the perfect ingredient to keep your mattress fresh. Pocket Springs
Individually wrapped pocket springs allow air to circulate between the springs, this combines with the base foam which has support notches in the perimeter that allow hot air to escape - which is forced out as the springs move under your weight.
Support Specs
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.
Gel-Infused Memory Foam
This memory foam layer alleviates pressure points by conforming to the contours of your body, for a sensation of weightlessness comfort. 5-Zoned Pocket Springs
Different gauge springs are used to create 5 unique support zones. These zones provide advanced orthopaedic support by mirroring your body's weight distribution from head to toe, so you can say goodnight to aches and pains. High-Density Base Foam
This gives the mattress the perfect foundation and creates a perimeter around the springs for added edge support - allowing you to sleep edge-to-edge, and extra support when sitting on the side of the mattress.
Fabric Specs
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.
Viscose Blended Cover
The Onebed X has a highly breathable viscose blended fabric, woven into a luxurious cubic dimple-protruding texture which you can gently feel beneath your sheets.
