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.
The Onebed X has a feel that will be perfect for the vast majority. It gradually transitions from a firmer supportive base to softer comfort layers for that ultimate feeling of comfort and support.
The Lite mattress is best suited for back and stomach sleepers, who enjoy a firm sleep surface as it's about an 8 on the firmness scale. The design of the mattress provides a subtle hint of body contouring, which in turn offers comfort and pressure relief while sleeping. The Noa Lite is the firmest of the Noa mattresses, the Noa mattress is a medium-firm feel and the Noa Luxe falls inbetween both.

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.

These elements create a highly comfortable, breathable and supportive mattress on both the lumbar and neck.

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.
The open-cell foam structure, airy pocket springs, infused cooling gel and highly breathable fabric keep the Onebed X refreshingly cool and comfortable, all night, every night. The Onebed X also isolates motion with paramount precision, passing the wine glass test with ease, so you stay deep in a state of deep sleep even if your sleeping partner is tossing and turning.
An eco-friendly, breathable cover, gel infused open-cell foams and individually pocketed springs provide optimal airflow, wicking away body heat and keeping you cool all night long. Adaptive transition foam provides outstanding motion isolation to localise your sleeping partner's movements so you sleep better.
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.
The Onebed X gives you the optimal balance between comfort and support thanks to softer memory foam layers, the zoned pocket springs, and firm base foam.
Cooling gel memory foam and individually pocketed, thick gauge comfort coils are designed to respond to your body and provide excellent contouring.
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.
Davina Foam
This breathable foam, used in the comfort layer, is extremely bouyant and helps with motion-isolation. Gel-Infused Memory Foam
The gel infusion helps keep you cooler. Charcoal Memory Foam
Charcoal eliminates odours, absorbs moisture and helps regulate temperature. Making it the perfect ingredient to keep your mattress fresh. Pocket Springs
Individually wrapped pocket springs allow air to circulate between the springs, this combines with the base foam which has support notches in the perimeter that allow hot air to escape - which is forced out as the springs move under your weight.
Cooling Gel Memory Foam
Memory foam with cooling gel wicks away heat away to keep you cool throughout the night. Individually Pocketed Springs
These springs are encased in a highly permeable mesh material that optimises airflow and enhances breathability.
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.
Gel-Infused Memory Foam
This memory foam layer alleviates pressure points by conforming to the contours of your body, for a sensation of weightlessness comfort. 5-Zoned Pocket Springs
Different gauge springs are used to create 5 unique support zones. These zones provide advanced orthopaedic support by mirroring your body's weight distribution from head to toe, so you can say goodnight to aches and pains. High-Density Base Foam
This gives the mattress the perfect foundation and creates a perimeter around the springs for added edge support - allowing you to sleep edge-to-edge, and extra support when sitting on the side of the mattress.
Cooling Gel Memory Foam
This premium cooling gel memory foam provides deep pressure relief, contouring and cushions your body in your pressure points. Transition Foam
This foam is used for zero partner disturbance, by localising your movements you won't wake up your significant other. Individually Pocketed Springs with Perimeter Edge Support
The base layer is made of highly responsive and supportive pocket springs that provide a subtle bounce and minimise motion transfer. Made of thick-gauge steel, these springs offer phenomonal durability and give just the right amount of bounce. A high-density foam encases the springs, this perimeter edge support allows you to sleep edge-to-edge on the mattress without feeling like you'll fall off and sit on the edge without feeling the springs.
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.
Viscose Blended Cover
The Onebed X has a highly breathable viscose blended fabric, woven into a luxurious cubic dimple-protruding texture which you can gently feel beneath your sheets.
Hand-Tufted Tencel Pillow-Top Cover
This ultra-breathable top cover is extremely soft to the touch. Tencel is naturally antibacterial and hypoallergenic which makes it ideal for allergy sufferers. The hand-tufting secures the inner layers and prevents them from moving. The cover is not removable so you may opt to use a mattress protector. Hand-Tufted Side Cover
The side cover is a polyester knit that is breathable and equally beautifully detailed. It further helps to keep the internal layers in place.
