Firmness Info

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.

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.

Comfort
What might feel right to your mate, doesn't feel right to you. That's why we've created our 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. Our customisable, double-sided Kloudcell™ comfort layer means you can choose what firmness level works for you. It comes in a medium-firm feel but if you’re on the lookout for something a little firmer, it's as easy as unzipping and flipping the comfort layer.
Ergoflex comparable only to TEMPUR® 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. 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 Ergoflex 5G consists of an unrivalled 9cms of open-cell 85kg/m³ high-density memory foam. Our unique Cool-Sleep airflow system encourages air to freely circulate thorough the mattress keeping you cool while you sleep. Our base layer provides perfectly weighted support for the upper layers and longevity of mattress performance.
Support
Designed to take the pressure off, a high-density reactive layer with precision cut support zones helps to provide an ideal foundation for sleeping no matter what position you prefer. Known around our neck of the woods as StayPut Edge Support, but all you need to know about our super stable edges is that the chances of anyone sliding off the bed are slim to none.
Our 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 better sleep. This confidence is matched by our customers making repeat purchases for additional mattresses time and time again. Our class-leading zero disturbance technology has been a distinctive feature for over 10 years. Promoting deeper, more restful sleep it reduces the likelihood of being woken by a restless sleeping partner. Indeed our ten-year guarantee is underpinned with confidence of a decade of success. Unlike other brands we know our mattresses stand up to our warranty claims - as we have done it in real life for over a decade.
