Firmness Info
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 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.
Completely Customisable Comfort
The Macoda Mattress is designed so that you can change your comfort setting at home. With a simple "unzip and flip" you can swap around the two top foam layers, changing your mattress to give you a firmer, medium or softer feel in a matter of minutes.
The Emma Comfort is just the right level of firmness, to ensure you get proper support balanced with unparalleled comfort. This makes the Emma Comfort perfect for all types of sleepers.
Firmness is the most sensitive and personal element of any mattress. Sleeping Duck have re-engineered the traditional mattress to make it modular, allowing you to pick (and even swap) the firmness that's exactly right for you. Simply choose between medium or firm initially. Rest assured, you'll be able to change the firmness via foam swaps for the first 100 nights for free.
Medium:
  • Suitable for side sleepers
  • Sinks in slightly while being supportive
  • Approximately a 6/10 on the firmness scale.

Firm:
  • Suitable for back sleepers
  • Still feels cloud like while maintaining a strong level of support
  • Approximately an 8/10 on the firmness scale.

Half Medium & Half Firm:
  • A different firmness on either side of the bed
  • Ideal for couples who have different firmness preferences.

Mattress Construction

Materials Overview
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.
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.
Macoda's four layer design allows you to experience memory foam, latex and springs giving you the combined benefits for your perfect night's sleep. The layers are:
  • Removable Bamboo Cover
  • Natural Latex
  • Gel Infused Memory Foam
  • High Density Support Foam
  • 5-Zone Pocket Springs with Edge Support.
The Emma Comfort mattress has been designed and dedicated for Australian sleepers. Made with two layers of foam:
  • Fresh Air Comfort Cover
  • Point Elastic Airgocell® Foam
  • Supportive HRX Foam.
The Sleeping Duck is made for sleepers who want the best of old and new. The Sleeping Duck is Australian designed and combines a combination of technologies in the one mattress:
  • Australian made AntiGravity surface foam (made from high density AirGrown polyurethane foam)
  • Australian made Precision Firmess Pads (made from high density AirGrown polyurethane foam)
  • The Motherboard: a multi-zoned steel spring system
These elements create a highly comfortable, breathable and supportive mattress on both the lumbar and neck.
This award-winning, GECA certified mattress is loved by their customers.
Comfort Info
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.
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 Macoda Mattress is designed by Australians for Australians with the Australian climate in mind. A super breathable mattress structure allows for increased airflow and heat dispersion. Less heat build-up means a cooler, sounder night's sleep. Bringing the bounce back into the bedroom! Premium natural latex combines with pocket springs to give you this added bounce. Sleep with fewer disturbances thanks to independent pocket springs.
The unrivalled cooling properties of the Emma Comfort will help keep your body cool and dry. The Zero Motion Technology allow you to sleep without interruption by the movements of your sleeping partner.
Appreciating that everyone is different, Sleeping Duck allows you to choose from a medium or firm mattress (or half-half on Queen and King sizes). Over the course of your 100 night trial you can change the firmness of your mattress depending on the way you are sleeping. These firmnesses can be adjusted with just the pull of a zip.
The ComponentAdapt customisation system empowers you to take full control of the comfort of your mattress. This is achieved via interchangeable Precision Pads that you can swap out for both you and your partner. After sleeping on your mattress, you can contact the SDHQ who can help you to customise and adapt the mattress with up to 256 combinations possible.
Support Info
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.
No matter your body type, Koala's Zero Disturbance® technology helps to evenly distribute your weight across the entire mattress.
By conforming to your unique body shape, weight is distributed and supported evenly. Without proper support, reduced circulation as well as aches, pains and discomfort are all too common. The unique 4-layer design of the Macoda mattress works collectively to give you the pressure relief necessary to make sure you're not just sleeping comfortably, but are waking up feeling great.
High-quality, zoned memory foam keeps your spine, hips, and shoulders aligned and supported in every possible position. The mattress distributes your body weight evenly and contours to your individual shape for ultimate pressure relief.
The Sleeping Duck Mach II has a multi-zone support structure to make sure every part of your body is wonderfully supported and comfortable. Pocket Springs are far more resilient and provide better support over a longer period of time. They're specifically designed to ease the human body to relaxation and relieve pressure points by varying the distribution of weight throughout the entire surface.
The mattress has superior edge support thanks to the reinforced spring perimeter through the use of 2.3mm springs on the entire border. This allows you to sleep edge-to-edge, making your Queen size feel like a King, and allowing you to sit or sleep on the edge without the rolling or sliding off feeling.
Independently pocketed springs create zero disturbance between you and your sleeping partner.
Comfort Specs
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.
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.
Gel Infused Memory Foam
The comfort layer is infused with 1000s of cooling gel beads that react to your body temperature, drawing heat away.
Point Elastic Airgocell® Foam
The ultra-comfy Airgocell® layer is point-elastic which allows one area of your mattress to compress without impacting the rest. If you share a bed with someone who moves while they sleep, you won't feel a thing. Airgocell® foam is also moisture-wicking to keep your sleep nice and dry. Supportive HRX Foam
The HRX foam in the base layer has open pores which enhances breathability, so you sleep cool and fresh.
AntiGravity Foam
The top layer was engineered in pursuit of the ultimate comfort. The foam which doesn't contain any latex or memory foam offers superior comfort and cushioning. It actually improves on the combination and provides increased pressure relief, buoyancy and breathability. The hyper-adaptable properties of the AntiGravity foam allows it to rapidly reshape around you as you move, allowing unimpeded movement, not achievable with the more rigid moulding that memory foam provides. It is produced via pressure expansion rather than chemical reactions which means it is 8x more open than latex and memory foam. Furthermore, it's all Australian made.
The use of the pocketed springs allows for far superior air circulation and ventilation than all-foam mattresses. This helps to keep your mattress cooler and drier.
Support Specs
G-7 Gel Memory Foam
This medium firmness layer is designed to evenly distribute weight without pushing against your pressure points and it lets you get the perfect amount of sink. ECO-Tex Memory Foam
The ECO-Tex comes in a medium-firm. It's designed to mould to the body and give bounce back. This cuddly foam layer contours to your body shape. Ergonomic Support Foam
The high-density, plant-based support foam has ergonomic grooves that support your spine's natural alignment and gives long-lasting durability.
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.
Natural Latex
This supportive layer of latex gives just the right amount of responsiveness and cushioning, without the sinking feeling. 5-Zone Pocket Springs with Edge Support
Weight distribution of the human body isn't a simple thing, so your mattresses shouldn't be either. With five different zones of support, areas of the body that need more get exactly that, which in turn helps to ensure spinal alignment for a therapeutic sleep. Macoda's 5-Zone system means you're always getting the support you need where you need it. Plus a firmer edge means you won't fall off and you won't sink in when sitting on the edge.
Supportive HRX Foam
The supportive HRX Foam layer is made with special zoning technology for proper hip, shoulder, and spinal alignment. This innovative foam helps your mattress contour perfectly to your individual body shape.
The combination of the changeable, high-density foam layer and the individually-wrapped pocketed spring multi-zone support layer, creates a system that is highly responsive to your needs.
The multi-zone spring system has three types of springs that are specifically engineered - 2.3mm springs around the very edge, 2.0mm springs through your back and hip zones and 1.8mm springs through your shoulder zone. The shoulder and hip zones conform whilst more support is provided to the lower back and head zones, therefore giving you the required alignment for a restorative night's sleep.
The use of these Twice Tempered IndestructSprings is not just for their ductility, strength and durability properties but to provide comfort and support through proper spinal alignment.
