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 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.
