Firmness preferences vary based on sleeping position, which is why we offer different mattresses to suit all needs. Back sleepers often benefit from firmer foam mattresses that promote spinal alignment, while side sleepers may prefer softer options for reducing pressure points around the shoulders and hips. Stomach sleepers, on the other hand, typically require extra support to prevent spinal stress.

The Koala Mattress and Koala Plus Mattress are mattresses designed for versatility, featuring a flippable comfort layer so you can choose between medium to firm support. The Koala Luxe Mattress takes customisation even further, offering a half-and-half comfort layer for couples with different preferences—reducing partner disturbance for a truly restful night.

For those looking for ultimate plushness, the Koala Luxe Mattress is our best mattress for luxurious comfort. Engineered with seven high-density support zones, it delivers superior contouring while reducing pressure points for more restorative sleep.

After nine years of perfecting our Kloudcell® technology, we've achieved the perfect balance of softness and support. The adaptive properties of our memory foam-like material help back and stomach sleepers feel properly supported while providing just the right cushioning for side sleepers. No matter how you sleep, our mattresses ensure a good night’s sleep every night.

If you’re looking for a quality mattress with firm support, the Koala Mattress or the Koala Plus Mattress with Flippable Firmness could be perfect for you. Simply flip the comfort layer to switch between 'medium-firm' and extra firm, tailoring the feel to your exact comfort level.

The Koala Mattress also offers a Partner Preference option, allowing couples to personalise their firmness levels for undisturbed sleep. Plus, our high-density materials provide additional support, helping to maintain structure and durability over time—so you won’t notice sagging after just a few years.

Available in a range of mattress sizes, our designs offer comfort with advanced support technology. Experience the perfect balance of firmness and pressure alleviation without compromising on comfort.

Sleeping next to a tosser? Our famous Zero Disturbance® technology is featured in all mattress types designed to absorb movement, ensuring you stay undisturbed when your partner tosses and turns. 

Whether you prefer a medium firm mattress or something plusher, Koala mattresses provide tailored support for different sleep styles and body weight, so both you and your partner get the best mattress experience—without compromise.

A Koala quality mattress is compressed, rolled, and vacuum-sealed into a compact box for quick and easy delivery straight to your door. Whether you need a super king or a more compact size, we offer a different mattress for every sleeper.

Made with high-density foam, Koala mattresses take around 3-5 days to fully expand to their correct shape and feel. However, you can sleep on it right away—it only gets better over time! If you need extra firm support, rest assured that your mattress will quickly adapt to provide the perfect balance of comfort and durability.

Upgrading to the right mattress? We’ve made it easy to dispose of your old one responsibly. In selected areas of Sydney and Melbourne, we've partnered with Soft Landing, a mattress-recycling social enterprise, to remove and recycle unwanted mattresses for a reasonable fee.

Once you’ve ordered your new mattress—whether it’s a single, queen, or king mattress—we’ll send you the details via email so you can book a pickup through Soft Landing.

For those outside these areas, check out Planet Ark's mattress directory to find recycling and reuse services near you. Choosing sustainable disposal isn’t just good for the planet—it also supports your overall well-being. Plus, enhance your sleep setup with one of our mattress toppers for extra comfort and support.

At Koala, we're committed to making a positive impact on the environment through thoughtful actions and genuine sustainability efforts.

Koala Mattresses feature foams certified by CertiPUR-US®, meaning they are made without ozone depleters and heavy metals, whilst promoting indoor air quality through low Volatile Organic Compounds (VOCs). We also integrate materials like carbon-zero TENCEL™, derived from sustainable wood sources, and recycled fibres, with the aim to reduce our footprint and promote the use of sustainable resources.

In addition to choosing thoughtful materials, we actively support environmental conservation by partnering with WWF and participating in the 1% for the Planet initiative. This means a portion of every mattress sale is invested in projects that aim to protect our planet's natural habitats and biodiversity.

Our approach to sustainability is about taking concrete steps to minimise our environmental impact, while supporting global efforts to preserve the planet for future generations.

Koala Mattresses only use foam that has been CertiPUR-US® certified, meaning it has been tested to meet CertiPUR-US®' rigorous standards for emissions, content, performance, and durability. The foam in our mattresses is made without heavy metals such as lead or mercury, there are no harmful phthalates present, and they are made without the use of ozone-depleting substances including methylene chloride and other CFCs. Koala Mattress foam has also been tested to have low VOC (Volatile Organic Compound) emissions for indoor air quality (less than 0.5 parts per million).

Choosing the right mattress is only part of the equation—your bed frame matters too. As long as your base provides adequate support and ventilation, it will work with any Koala Mattress, including our memory foam mattresses. If you're using a slat base, keep the slats no more than 7.5cm apart to ensure proper mattress support.

While posture slats can be used, they may make the mattress feel softer than intended. For the best comfort—especially if you prefer extra firm support—we recommend straight (flat) slats.

We don’t suggest placing your mattress directly on the floor without ventilation, as this can cause moisture build-up. Similarly, adjustable beds aren't ideal, as bending or folding the mattress may damage the core or supportive layers.
