Two of Australia's most popular foam mattresses compared head-to-head. Koala vs Ecosa — construction, cooling, firmness, trial periods, warranty, and who each one actually suits.
Koala and Ecosa are two of the most popular mattress brands in Australia — and for good reason. Both are Australian-focused, both sell high-quality foam mattresses at competitive prices, and both come with generous trial periods and warranties. But they take quite different approaches to mattress design, and the right choice between them depends on your priorities.
This detailed comparison looks at comfort, construction, firmness, cooling, trial periods, warranty, price, and who each mattress suits best.
Koala launched in Australia in 2015 and has grown into one of the country's most recognised mattress brands. Their Original Mattress uses Kloudcell foam — a proprietary open-cell foam developed to sleep cooler than traditional memory foam. It's available in one firmness level (medium) and comes with a 120-night trial and 10-year warranty. Koala also offers a hybrid mattress for those who want pocket spring support.
Ecosa is known primarily for its innovative adjustable firmness system. Their flagship mattress uses three distinct foam layers that can be rearranged to create different firmness profiles — Soft (G-5 on the Ecosa scale), Medium (G-7), or Firm (G-9). This makes it one of the most versatile mattresses in the Australian market. Ecosa offers a 100-night trial and a 15-year warranty, the longest standard warranty offered by any major brand in Australia.
The Koala Original uses three foam layers: a top comfort layer of Kloudcell open-cell foam (designed for cooling), a middle transition foam layer, and a high-density support base. The total height is approximately 25cm. The cover is made from a soft knitted fabric with some stretch for contouring.
The Ecosa uses three foam layers that can be reordered: a top layer of eco-friendly memory foam, a middle layer of pressure-relieving Ecofoam, and a base support layer. The layers connect via a zip-off cover, allowing you to physically rearrange them to change the firmness. Total height is around 25–26cm.
Koala offers one standard firmness — a comfortable medium that suits the majority of back and side sleepers. It's responsive and slightly bouncy for foam, without the heavy sinking sensation of some memory foam mattresses.
Ecosa's adjustable system gives you genuine choice. If you buy the mattress and the default configuration doesn't suit you, you can rearrange the layers yourself. This is a genuine differentiator — particularly useful for households where preferences change, for couples who compromise on firmness, or for people unsure what firmness they need.
This is an area where Koala has a deliberate advantage. The Kloudcell foam was specifically designed to be more breathable than traditional memory foam, and Koala markets this as a key feature. In practice, the Koala does sleep noticeably cooler than many foam competitors.
Ecosa uses standard memory foam in its comfort layer, which has better heat retention. The brand has added some breathability features over the years, but if you're a hot sleeper in Australia, Koala's cooling credentials are more established in this comparison.
Both are all-foam mattresses, so both perform well on motion isolation. Neither will transfer significant movement to the other side of the bed. There's minimal practical difference between them on this measure.
The Koala trial period is longer (120 vs 100 nights), giving you more time to test the mattress at home. But Ecosa's 15-year warranty is one of the best in the industry and reflects confidence in their product's durability. Both offer free returns within their trial periods.
Pricing is similar. Both brands run regular promotions and discount periods, particularly around sales events. Check current prices directly on each brand's website.
Both are excellent mattresses at a similar price point. Koala edges ahead for hot sleepers thanks to its Kloudcell cooling technology and the longer trial period. Ecosa has the advantage for anyone who values firmness flexibility or wants the reassurance of a 15-year warranty.
If you genuinely don't know what firmness you need, Ecosa is the safer purchase — the ability to adjust the feel without returning the mattress is genuinely valuable. If you're a hot sleeper or simply want the most popular Australian foam mattress, Koala is a proven choice.

Always look for at least 100 nights. Koala (120 nights) and Sleeping Duck (100 nights) offer some of the best trials available. A trial lets you test the mattress through different seasons including Australian summer.
A 10-year warranty is standard for quality mattresses. Ecosa offers 15 years, which is exceptional. Be wary of brands offering less than 5 years.
All-foam mattresses offer excellent motion isolation but can sleep warm. Hybrid mattresses use pocket springs under foam, improving airflow significantly — important for Australian summers.
Medium is most versatile for side and back sleepers. Stomach sleepers generally need firmer. If unsure, Ecosa lets you adjust firmness.
