The Koala Original Mattress has a medium feel, making it suitable for side-sleepers, back-sleepers.
It uses foam construction to provide:
The Koala Original is arguably Australia's most recognisable mattress-in-a-box brand, and for good reason. Since launching in 2015, Koala has delivered a solid all-round mattress that suits the majority of Australian sleepers at a competitive price point.
The Koala Original uses a three-layer foam construction: a comfort layer of proprietary Kloudcell® foam, a transition layer, and a high-density support base. The result is a medium feel that works well for side and back sleepers. You sink in slightly without that "stuck" feeling common to traditional memory foam.
Australian summers demand good airflow. The Koala performs reasonably here — the open-cell Kloudcell® foam allows more airflow than dense memory foam, though it's not as cool as a hybrid mattress with coils.
Excellent. Couples will appreciate that movement on one side barely registers on the other — great for light sleepers sharing a bed.
A Queen starts at $1,299 AUD. For a quality all-foam mattress with a 120-night trial and 10-year warranty, that's strong value in the Australian market.
The Koala Original earns its reputation as Australia's best-selling mattress for a reason. It's comfortable, fairly priced, and backed by one of the best trial and warranty packages on the market. Highly recommended for side and back sleepers.
The Koala Original Mattress delivers consistent, reliable comfort for most Australian sleepers. The medium feel suits the widest range of positions and body types.
Support is the most important factor when choosing a mattress — more important than comfort, price, or brand name. A mattress that fails at spinal alignment will cause morning stiffness and back pain regardless of how comfortable it feels in the short term.
The Koala Original Mattress performs well in this area by:
It's particularly beneficial for side-sleepers and back-sleepers.
One important note: spinal alignment also depends on pillow height and bed base quality. A foam mattress on slats wider than 7cm will undermine even the best mattress. Ensure your base is appropriate before attributing any alignment issues to the mattress itself.
If you sleep hot — and in Australia's climate, many people do — cooling is a non-negotiable factor. We weight temperature regulation at 20% of our overall score, higher than most US-based review sites, because Australian summers genuinely demand it.
As a foam mattress, the Koala Original Mattress uses open-cell foam construction to improve breathability compared to traditional dense memory foam. This helps reduce heat buildup, though it won't match the airflow of a hybrid mattress with a pocket spring base.
For very hot sleepers in Queensland or WA, pairing with linen or bamboo bedding will significantly improve overnight temperatures regardless of the mattress chosen.
The Koala Original Mattress is constructed using a foam system designed for long-term durability in the Australian market. The material stack is:
These materials are CertiPUR-US certified (or equivalent), meaning they've been tested for harmful chemicals including formaldehyde, heavy metals, and VOCs. The cover is typically a knitted fabric designed for breathability and stretch.
In terms of durability, a well-maintained Koala Original Mattress should last 7–10 years under normal usage. Using a quality mattress protector from day one significantly extends this lifespan by preventing moisture and debris from reaching the foam layers.
In Australia, the Koala Original Mattress is priced at approximately $1,050 AUD for a Queen. This sits in the mid-range tier of the Australian mattress market.
Compared to similar mattresses at this price point, it offers:
Koala regularly runs promotional discounts of 15–30% during major Australian sale events. Checking our deals page before purchasing can save you $150–$400.

A new mattress works best with the right accessories. These are the three things most people buy alongside a new Koala — all available on Amazon.com.au with fast delivery.
Required to keep your 10-year warranty valid. Most brands void warranties for stained mattresses.
The right pillow height completes your spinal alignment — a good mattress with a bad pillow still causes neck pain.
Foam mattresses need slats under 7cm apart. A wrong base causes premature sagging and voids warranty.
The Koala Original Mattress is a solid mid-range choice for Australians looking for a balance of comfort, support, and affordability. The medium firmness suits the widest range of sleepers, and the 120-night free trial removes most of the purchase risk.
Where it excels: pressure relief and motion isolation — particularly strong for side sleepers and couples. Where it's less ideal: single firmness — no adjustment option.
For most Australian sleepers, it's a reliable, well-made mattress that delivers what it promises. The 10-year warranty and generous trial make it a low-risk purchase.
