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 Koala Calm As mattress has a double-sided comfort layer that you access by unzipping the cover, and flip this layer over. You can choose between medium-firm support and firmer support. Koala recommend trying the medium-firm default side first.

The Calm As mattress is the firmest, the Koala in the middle, and the Soul Mate is not quite as firm. The same order applies when using the softer side.

Designed with a double-sided comfort layer that gives you the choice between medium-firm support and firm support. Just unzip and flip it to find what works for you.

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!)

No more tossing and turning, as Koala mattresses have a Zero-disturbance® layer meaning you'll sleep soundly no matter who you sleep next to. It's like sleeping in separate beds, without giving up the cuddles.

All Koala mattresses come with an anti-bacterial treatment to help keep dust-mites and other nasties away.

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.

StayPut Edge Support is effectively a firmer foam perimeter that creates super stable edges so that you can sit or lie right on the edge of the mattress without falling off.

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.

The ultra cooling comfort layer made with COOLMAX® fibre is easy going on your skin, and helps your body feel cool and dry, even on muggy nights.
The ZoneOut Transition Layer is fitted with air tunnels meaning any excess or unwanted heat is efficiently dissipated which helps make for a cooler night's sleep.

Bamboo charcoal memory foam with nifty ventilation holes is used in the transition layer for its naturally antimicrobial properties and to promote airflow through these perforations.
The foam springs furthre allow airflow in all the right areas to help give you a cooler night's sleep.

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).

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.

The Koala Calm As mattress has multi-layered zoning.

3 Zone Transition Layer
This foam layer has 3 high density targeted support zones to disperse your weight while providing extra support for your lower back.

3 Zone Support Foam Base
This high-density reactive layer has 3 precision cut support zones is designed to take the pressure off, it offers a firmer support base right beneath the hips that prevents your body from sinking into the mattress. This helps you to maintain a healthy sleeping posture.

Designed to work with your body, not against it, the 5 Zoned Adaptive Foam Springs are crafted to react to your body's slightest movements. Each spring offers tailored support without compromising Koala's famous Zero Disturbance® technology. 5 zones offers variable support across your whole body, including your head, shoulders, lower back, thighs and feet to help relieve pressure and give you a great night's sleep.
Bamboo charcoal memory foam in the layer above further relieves pressure.
