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 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.

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.

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 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 Koala mattress has three foam layers:

  • Tencel™ Lyocell Sleep Surface
  • 7cm Flippable Comfort Foam Layers
  • 3 Zone Support Foam Base
  • Anti-Slip Base.

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.

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.

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.

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.

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.

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

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.

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.

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.

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.

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.

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.

Fabric Specs

The grey bottom cover ensures perfect air circulation, so you breathe easy all night long (made from 87% polyester and 13% polypropylene) plus it has handles for easy setup. The side cover is 100% polyester.

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.
