Flippable / Reversible Firmness
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.

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.
MEDIUM FEEL MATTRESS: A foolproof combination of individually wrapped iCoil Pocket Spring and high density and comfort foam topped with knitted jacquard fabric quilting provides a breathable, comfortable and supportive base to sleep on. Incorporating no flip technology. ZERO PARTNER DISTURBANCE: Individually wrapped tempered steel coils move independently to contour precisely to your body, provide consistent distribution of support throughout the mattress and lessen partner disturbance. Undisturbed, restorative sleep that'll have you daydreaming about bedtime.
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.
STABLE EDGE SUPPORT: Tightly knit edges around the mattress and reinforced surrounding tempered steel coils to maximise edge support. SAFE FROM HARMFUL SUBSTANCE MATTRESS IN A BOX : Only the Highest Quality of Foam is used in Zinus Mattress. The mattress foam is CertiPUR-US Certified for durability, performance, and content. Patented smart technology that allows all of our mattresses to be packed efficiently in one box and sent to your door
