Firmness Info
The top layer of latex foam is soft and responsive whilst the memory foam (second layer) ensures your body contours to its natural alignment. The layers can also be rearranged if you prefer a softer or firmer mattress. The medium-firm, by far the most popular sleep configuration, your Onebed mattress will arrive with the layers automatically arranged in this order. If you prefer a plusher mattress (medium), simply unzip and switch the latex and memory foam layers around for a softer night's sleep. For those who can never quite find a firm enough mattress, unzip and switch the high-density foam to the top for a configuration sure to set you straight.
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 Onebed mattress is the perfect sleep surface for a revolutionary sleep experience. It is a three-layer foam construction:
  • Plush Polyester Cover
  • 4cm Dunlop Latex (top layer)
  • 4cm Viscoelastic Memory Foam (middle layer)
  • 17cm High-Density Polyurethane Foam (bottom layer).
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 unique cushioning effect from the combination of latex and memory foam provides zero-motion transfer, meaning all movement stays on the side of the bed where it belongs. You'll enjoy an uninterrupted sleep without being woken by your 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
No one likes the feeling of a sinking, lumpy mattress. So this mattress has no springs but still has the essential cheeky bounce, so you'll enjoy that balanced, springy feel without the quicksand collapse. Springy latex and high-density memory foam come together to create the ideal balance of comfort and support for all body types.
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
Dunlop Latex
By using latex as the top layer, Onebed mattresses are designed to draw heat away from the sleep surface. Enjoy the difference of optimised air flow for a cooler, more comfortable night's sleep. All layers use highly breathable foam, which allows air to flow freely throughout the layers, keeping the mattress 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
Dunlop Latex
A generous 4cm layer gives you that cheeky bounce needed for night time activities, without the need for springs. Memory Foam
High-density viscoelastic memory foam provides unrivalled pressure relief. As you body heats up, memory foam moulds to the natural contours of your body. High-Density Polyurethane Foam
This HD foam provides support for sleepers of all sizes and gives the longevity required to last for years to come.
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
Plush Polyester Cover
The cover is woven from plush polyester and has large comfortable dimples. This aesthetically-pleasing design is also practical as the cover is removable and washable.
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.
