The Ecosa mattress has a triple layer adjustable foam construction. The layers are interchangeable for those who wish to change the firmness level of their mattress. Easily swap from medium to medium-firm or firm. Perfect if you're not sure on your firmness preference or have changing needs over time.

The Ergoflex mattress is a result of over a decade of research and development. This one 'perfect' mattress is rated medium-firm and is optimised with the highest-quality materials available, and has thousands of 5-star reviews from customers in Australia, the UK, and all over the globe.

The Koala 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.

Engineered for better nights, the Ecosa mattress comes in three interchangeable layers for optimum comfort and support. The layers are:

• Removable Tencel Cover
• Waterproof Inner Cover
• 6cm G-7 Gel Memory Foam
• 2cm ECO-Tex Memory Foam
• 17cm Ergonomic Support Foam.

As the most premium mattress in a box in Australia, the Ergoflex™ 5G comprises of the following layers:

• Luxurious Tencel® Cover
• Protective Inner Cover
• 9cm High Density Visco-Elastic Memory Foam (Density: 85kg/m³)
• 5cm Cool-Sleep Foam
• 9cm High-Resilience Foam Base.

The Koala mattress has three foam layers:

• Cooling Tencel™ cover Lyocell Sleep Surface
• Kloudcell® 6cm of Med-firm/firm flippable comfort layer
• 3 Zone Support Foam Base
• Anti-Slip Base.

The Ecosa sleeps comfortably cool thanks to three key design elements: memory foam infused with gel beads, pincore holes for air circulation, and ergonomic grooves in the support layer. Together they promote airflow and dissipate heat.

Ergoflex is comparable only to TEMPUR®, yet it is technically more advanced and superior in performance to every alternative both in this price range and beyond. As a result it is renowned for delivering deep restorative sleep.

The OEKO-TEX® Standard 100 certification makes it a great option for asthma and allergy sufferers as the mattress is resilient to the growth of bacteria, moulds, mildew and fungi.

Class-leading zero disturbance technology promotes deeper, more restful sleep as it reduces the likelihood of being woken by a restless sleeping partner. Just watch the video above to see how little disturbance is caused by a parachuter landing on the mattress (spoiler: the wine glass doesn't even fall over!)

No more tossing and turning, as Koala mattresses have a Zero-disturbance® layer meaning you'll sleep soundly no matter who you sleep next to. It's like sleeping in separate beds, without giving up the cuddles.

All Koala mattresses come with an anti-bacterial treatment to help keep dust-mites and other nasties away.

The Ecosa was designed for back support and adjustability (1 in 3 Aussies suffer from poor sleep quality). Three premium foam layers give flexibility in adjusting the firmness, whilst allowing you to relax into a deep, restorative sleep and wake up feeling pain-free and reinvigorated.

The Ergoflex 5G mattress is the only true high density memory foam mattress available. Designed to mould itself to the contours of your body it provides instant comfort, more support and orthopaedic pressure-relief. It is recommended by Practioners for those that suffer from back pain, fibromyalgia, circulation problems and joint complaints or to those simply in need of a good night's sleep.

No matter your body type, Koala's Zero Disturbance® technology helps to evenly distribute your weight across the entire mattress.

G-7 Gel Memory Foam
This contains gel-infused particles to help stabilise temperature and keep you cool through the night. As shipped, this layer will be on top giving you the medium firmness.

ECO-Tex Memory Foam
This open cell foam is bouncy like latex yet more durable and breathable.

Both comfort layers have pincore holes that allow air to circulate freely through all three layers of the mattress which helps you stay at the perfect temperature.

Ergonomic Support Foam
The ergonomic grooves also allow the mattress to breathe.

High Density Visco-Elastic Memory Foam
The foam design has billions of ball-shaped open cells that give added breathability than traditional memory foams which have been known to sleep hot.

Cool-Sleep Foam
This unique Cool-Sleep airflow system encourages air to freely circulate thorough the mattress keeping you cool while you sleep. It does this by using a specially-engineered foam design that instead of being a rectangular block of foam it more resembles an upside down egg carton, which has channels for temperature-regulation. These work in combination with the 3D mesh panels in the outer cover to disperse heat.

Flippable Comfort Foam Layers
This sensitive and soothing comfort layer has been specifically designed to absorb and release moisture, making nodding off a breeze. Regardless of the climate or the season, you'll get a good quality sleep with a Koala mattress. The mattress layers are designed to give you constant airflow which means you'll enjoy a cooler night's sleep.

G-7 Gel Memory Foam

High Density Visco-Elastic Memory Foam
This comfort layer gives the optimum level of support, shifting responsively to your movements. You will experience a feeling of pure weightlessness as every part of your body is supported and cradled which alleviates pressure points (such as your hips, back, and shoulders).

High-Resilience Foam Base
This base layer provides the precise support for the upper foam layers and gives the mattress its performance longevity. Ergoflex mattresses stand up to their warranty claims - Ergoflex's ten-year guarantee is underpinned with the confidence of having had more than a decade of success and continuing.

3 Zone Support Foam Base
To help create an ideal foundation for sleeping, three targeted high-density precision cut support zones are designed to take the pressure off. No matter what position you prefer, overall it helps make a better sleeping experience. Firmer support right beneath the hips prevents your body from sinking into the mattress. This comes in real handy when it comes to helping you maintain a healthy sleeping posture. This firmer support base prevents you from sinking too deep into the mattress.

Removable Tencel Cover
Made with 40% Tencel and 60% premium polyester. This breathable, flexible, and removable soft-touch cover has a zipper meaning it is machine-washable and allows easy access to the layers to easily adjust the firmness.

Waterproof Inner Cover

Protective Inner Cover
This super fine inner cover protects the core foam layers.

Tencel™ Lyocell Sleep Surface
The sleep surface is made with a Tencel™ Lyocell fibre (65% polyester, 35% Tencel™ Lyocell) this top fabric is incredibly breathable to keep your body temperature under control and the mattress dry. Tencel is eco-friendly and made from sustainably sourced wood, the Tencel fibres are more absorbent than cotton, softer than silk, and cooler than linen.
