What is the Koala Mattress made of?
The Koala Mattress is made up of two layers: a support layer, and a comfort layer. The bottom layer consists of high density foam designed for optimal spinal support, and the top layer is called Kloudcell which is our own proprietary blend of polyurethane open cell foam. Kloudcell is named so due to it feeling soft as if you’re floating on a cloud!
The Koala Mattress is 100% Australian made, and the foam has the Good Environmental Choice Label (GECA). GECA certifies that our mattress foam has undergone a rigorous, and thorough assessment to verify it has highest environmental credentials, and represents the leading environmentally preferable option in the marketplace. The Koala Mattress foam was assessed across its entire lifecycle to be better for the environment, have a lower impact on human health and have been ethically made. For example, there are no heavy metals such as lead or mercury, no phthalates, low VOCS, and no ozone-depleting substances like methylene chloride.
Why do some foams become infested with microbes?
Many variations of polyurethane foam can possess all the requirements for bacteria, mold, yeast, and algae to develop, and flourish in it’s environment. Some foams that contain more natural elements are an optimal food source for microbes, wheres others collect organic debris within their environment. Both of these will be damaged by microbial growth over a period of time.
What is antimicrobial foam?
Antimicrobial foam contains antimicrobial additives that prevent the growth of bacteria, mold, and mildew in, and on polyurethane foam. This is done by “directly applying the additive to the liquid polyol stream prior to the polymerisation reaction. The antimicrobial additive becomes a permanent part of the structure once it is incorporated into the polyurethane foam. As a result, the antimicrobial treatment lasts for the effective life of the product.”
Below is an example of the difference between an untreated polyurethane foam, and an Ultra Fresh treated polyurethane foam.

Does Koala use antimicrobial foam?
Yes, Koala uses antimicrobial polyurethane foam for our mattresses to ensure the safety of our customers while they sleep, and maintain the structural integrity of our mattresses. The foam we use is treated by Ultra Fresh which protects our mattress from the “unwanted effects of microbial growth, including mal-odors, staining and product degradation”.
In addition to having an antimicrobial foam, Koala’s mattress has a TENCEL ™ Lyocell blend mattress cover. TENCEL ™ Lyocell fibers absorb moisture efficiently. In comparison to polyester and synthetics, there is less available moisture formed on the surface of the fiber for bacteria to grow. Consequently, TENCEL ™ Lyocell fibers provide a less favorable environment for bacterial growth, offering better hygienic qualities to fabrics.
