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.
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.
This mattress has all the needed features to give you the sleep you deserve regardless of your preferred sleeping position. The best way to find out whether a mattress is right for you, is from the comfort of your own home. That's why Emma give you 100 nights to test the Emma Diamond Hybrid Mattress. If you decide its not quite right, you can send it back for free.

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.
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).
Take your sleep to the next level with the Emma Diamond Hybrid. The Emma Diamond Hybrid Mattress consists of four different layers:
  • Climate-Regulating and Elastic Cover
  • Diamond Degree® Graphite Foam
  • Adaptive Comfort Foam
  • Pocket Springs
  • HRX Foam.
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 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.
The excellent cooling and heat dissipation properties of the Diamond Hybrid mattress helps your body maintain the ideal sleeping temperature, enabling you to sleep longer in the deep sleep phase and feel more well rested when waking up.
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.
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.
A hybrid mattress without compromise: the Diamond Hybrid mattress completely moulds to your body, thanks to its adaptive comfort foam and pocket spring construction.
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.
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.
Diamond Degree® Graphite Foam
This foam layer has an infusion of diamond and graphite particles, this innovative coating quickly dissipates excess heat away; extending the duration of your deep sleep phase. Pocket Springs
Hundreds of individually encased steel pocket springs ensures superb ventilation by allowing air to circulate.
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.
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.
Diamond Degree® Graphite Foam
The low rolling-resistance of the Diamond Degree® graphite foam requires less effort from your body when you involuntarily toss and turn during sleep, meaning you're less likely to wake yourself up or be disturbed by your partner in the middle of the night. Adaptive Comfort Foam
The ergonomically designed adaptive comfort foam layer adapts to your body and optimally distributes body pressure, allowing you to sleep comfortably regardless of your build or sleeping position (back, side, stomach). Pocket Springs
Individually encased steel pocket springs provide dynamic body adaptation, while also allowing for movement isolation to minimise disturbances brought about by movements. HRX Foam
The supportive HRX foam layer provides optimal back support thanks to incisions in the foam and gives superb durability.
