Firmness Info

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.

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

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 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

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.

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

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

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

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.

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

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.

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.

Fabric Specs

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.

Anti-Slip Base
The anti-slip base fabric is 100% polyester with PVC dot which helps keep your mattress securely in place.

BreatheTech Cover
The vortex spun bamboo yarn top cover is designed for maximum breathability and ease of switching foam layers. Soft and silky to touch, it also has natural anti-microbial properties that keep it fresher for longer. The cover easily unzips and is machine washable. Plus no annoying buttons that you feel with tufted mattresses. This high performance bamboo yarn is knitted to ensure optimal breathability for air and liquid, to ensure it remains dry and cool.
