Firmness Info

The Emma Zero Gravity mattress offers an exceptional level of firmness, thanks to its AirGrid Technology. This unique feature dynamically adapts to body movement, providing instant and optimal pressure relief. The individually encased steel pocket springs enhance the firmness, contributing to superior breathability and prolonging mattress lifespan. With this mattress, you get firmness that cradles your pressure points, ensuring maximum comfort and a feeling of sleeping on a cloud.

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.

Ergonomic Handles
Comfort
Sweaty nights are a thing of the past. The Zero Gravity has large air channels with improved airflow that keep the mattress from retaining heat and allowing it to maintain the ideal temperature all night long. The gel material is cool to the touch which helps you unwind and fall asleep faster.
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.
Support
No more back or neck pain with the Zero Gravity mattress. Thanks to our premium AirGrid® technology, along with a multi-zone pocket spring system, supports the wider areas of your back, cradling the pressure points across your body. This brings maximum pressure relief, support, and comfort while you sleep.
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.
