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.

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.

Zinus iCoil

Is Zinus non toxic?

Yes, Zinus mattresses are considered safe and non-toxic. They are certified by CertiPUR-USยฎ, which means the foam used in the mattresses is tested to meet specific criteria for indoor emissions, content and physical performance. It signifies that the foam does not contain harmful substances such as formaldehyde. Therefore, Zinus mattresses are not classified as dangerous.

Can I remove my Zinus mattress cover?

No, you should not attempt to remove the cover of your Zinus mattress, as it does not have a zipper and is not designed to be taken off. This cover functions in conjunction with the mattress itself and removing it may compromise the fire safety barrier and could potentially void the warranty. It's worth noting that the cover is not washable, so if necessary, you should spot clean it in place.

Is Zinus a Chinese brand?

Yes, Zinus is a global brand with origins in South Korea, founded by Youn Jae Lee in 1979. However, all of Zinus mattresses are currently manufactured in Xiamen, China. The company originally started with making outdoor tents before evolving into an industry leader in the mattress and furniture market.
