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. |

FAQs
Emma Zero Gravity
Why is the Emma Zero Gravity so special?
The Emma Zero Gravity mattress stands out due to its innovative design that maximizes comfort, breathability, and support. Its unique AirGrid layer, a hyper-elastic material with large air channels, adapts instantly to movement and cradles pressure points, ensuring you experience a feeling akin to sleeping on clouds. Coupled with a novel system that combines foam, pocket springs, and AirGrid, the mattress provides optimal pressure relief in all sleep positions. Moreover, the advanced motion-isolating technology in the Emma Zero Gravity mattress minimizes disturbance from partner movements, promoting uninterrupted sleep. These distinctive features make the Emma Zero Gravity a standout choice, offering a sleep experience that feels almost weightless.
Does an Emma mattress smell?
Like many new mattresses, an Emma mattress may initially exhibit a slight smell, often referred to as "off-gassing." This common occurrence is due to the release of volatile organic compounds (VOCs) produced during the manufacturing process of synthetic foams. While typically harmless, the smell can be unpleasant to some. However, it should dissipate within a few hours to a few days if the mattress is left to air out in a well-ventilated room. It's important to note that as of my last update in September 2021, Emma mattresses are CertiPUR-US certified, indicating they are made without harmful chemicals and have low VOC emissions. For any concerns regarding smell, reaching out to Emma's customer service department is advised.
Does the Emma Zero Gravity Hybrid get hot?
The Emma Zero Gravity Hybrid Mattress incorporates specific features designed to prevent overheating and promote a cool sleep environment. Its Zero Gravity Technology ensures maximum airflow and thermoregulation through air holes present in the AirGrid layer, facilitating a cool sleep surface that allows you to drift off faster. Additionally, the AeroFlex® Pocket Springs, each individually encased, adapt dynamically to body movement and offer superior breathability compared to standard foam mattresses. The mattress also features the Emma UltraDry™ Breathable Cover, which is not only super soft to touch but also removable and easy to wash. This ensemble of features works cohesively to maintain a cool sleeping environment and prolong the lifespan of the mattress.
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 CHOICE® 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.
