| 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. | Based on our research, most people prefer a mattress that is firm but not too hard. Eva mattress is a medium firm mattress which puts it in the region of a 7-8 out of 10 with 1 being very soft and 10 being very hard. This is the ideal firmness for a supportive sleep. |

| 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 Kloudcellโข comfort layer means you can choose what firmness level works for you. It comes in a medium-firm feel but if youโre on the lookout for something a little firmer, it's as easy as unzipping and flipping the comfort layer. | Our unique double pocket spring layer acts as a great source of ventilation. The open structure allows air to circulate freely thus providing a cooler sleep. In contrast, a full block of foam acts as a barrier to ventilation and traps heat in it. This makes the mattress hot, especially during the Australian summer! Memory Foam infused with millions of gel beads to maintain perfect temperature through the night, this material adapts to your body to redistribute heat and offer pressure relief. Eva's latex open cell and pinhole structure allows it to flex and breathe. |
| 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 unique combination of micro and pocket springs provide support where it matters. Our 5 zone pocket springs provide optimal support from head to toe ensuring the body is properly aligned, no matter the sleeping position. The springs at the edges are also developed with thicker premium grade spring, eliminating the feeling of falling off. The micro springs bring an additional support layer closer to the surface, providing an extra bouncy feeling when sleeping on it. The patented Micro Springs technology creates air flow through the mattress, relieves pressure wherever it's most present during sleep and lends support as close to the body's contours as possible. Superior Edge Support: supported by robust springs along its side pockets, an Eva mattress makes it near-impossible to fall out of bed or sink down when banished to the mattress's edge by your partner, cat or sleeping habits. This side-spring technology encourages sleepers to utilise and enjoy the mattress's full, lush and sprawling surface. |

FAQs
Koala Calm As
Is Koala calm as worth it?
The Koala Calm As mattress, known for its comfort, support, and cooling features, is competitively priced and could be a worthwhile choice if it aligns with your sleep preferences and needs. However, individual comfort varies, so consider your personal sleeping habits and any physical conditions before purchasing.
How long will a koala mattress last?
While it's challenging to provide an exact lifespan for the Koala Calm As mattress since it's a relatively new product, we can look at general guidelines and the quality of its construction. Mattresses typically last between 7-10 years, with high-quality ones potentially exceeding this range. The Koala Calm As mattress has been recognized for its quality, receiving the 'Product of the Year' award in the mattress category for 2022 and being CHOICEยฎ recommended. It's a well-constructed product that should provide good durability, but actual lifespan can vary depending on factors such as usage and care. Regular rotation, for instance, can help extend the life of a mattress.
Can the Koala Calm as mattress go on slats?
Yes, the Koala Calm As mattress can be placed on slatted bed frames. However, it's important to ensure that the slats are not too far apart. As a general rule, the gap between slats should be no more than 3 inches (or about 7.6 cm) to provide adequate support and prevent sagging. If the slats are too far apart, it may affect the mattress's support and potentially its lifespan. Always make sure your bed frame is in good condition and provides sufficient support for your mattress.
Eva
What is Eva mattress made of?
The Eva Comfort Classic Mattress is a hybrid mattress made of memory foam, high-density foam, latex, and pocket springs, providing a balance of comfort and support. Produced in a family-owned business in Foshan, China, Eva is an Australian company
Can you flip an EVA mattress?
No, the Eva mattress is not designed to be flipped. It is a one-sided mattress, meaning that the comfort layers are only intended to be used on one side. The mattress is constructed in a way that the top side is optimized for comfort and support, while the bottom side is typically a non-slip surface that helps keep the mattress in place on the bed frame. It is recommended to rotate the mattress occasionally to promote even wear, but flipping it over is not necessary or recommended for maintaining its intended comfort and support.
How long does it take for Eva mattress to inflate?
Most memory foam or hybrid mattresses, like the Eva mattress, take about 24-72 hours to fully inflate after being unpacked from their compressed packaging. It's usually okay to sleep on them after a few hours, although this can depend on the brand's specific instructions and environmental factors such as temperature and humidity.
