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.
Brand Overview
Koala
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
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.
Construction & Materials
Koala Original
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.
Ecosa Mattress
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.
Firmness & Feel
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.
Temperature & Cooling
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.
Motion Isolation
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.
Trial Period & Warranty
- Koala: 120-night trial, 10-year warranty
- Ecosa: 100-night trial, 15-year warranty
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.
Price (Queen)
- Koala Original: approximately $1,299 AUD
- Ecosa Mattress: approximately $1,199 AUD
Pricing is similar. Both brands run regular promotions and discount periods, particularly around sales events. Check current prices directly on each brand's website.
Who Should Choose Koala?
- Hot sleepers who want the most breathable foam option
- People who want a longer trial period (120 nights)
- Side and back sleepers who are happy with a medium firmness
- Those who want a well-established, widely reviewed Australian brand
Who Should Choose Ecosa?
- Anyone unsure about their ideal firmness — the adjustable system removes the guesswork
- Couples with different firmness preferences who want to experiment
- Those who want the longest warranty available (15 years)
- People who've tried medium foam mattresses and found them too soft or too firm
Our Verdict
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.

Performance Comparison: Key Areas
Comfort & Pressure Relief
Both mattresses deliver solid pressure relief for side sleepers and those with shoulder or hip sensitivity. Koala's medium firmness sits in the sweet spot for most Australian sleepers — responsive enough for back sleeping, contouring enough for side sleeping. Ecosa's adjustable design means you can dial in the exact comfort level you need. If Koala's medium feels too firm or too soft after a week, you're committed. With Ecosa, you can physically rearrange the layers yourself at no cost.
Temperature Regulation
Koala's Kloudcell technology is specifically engineered for Australian heat. The open-cell structure allows air to circulate more freely, making it noticeably cooler than standard memory foam. Ecosa uses conventional memory foam, which naturally retains more body heat. For Brisbane summers or hot sleepers, this difference is meaningful. For temperate climates or those who don't run hot, both perform adequately.
Edge Support
Both mattresses offer adequate edge support for foam. You won't have significant roll-off issues, though neither matches the perimeter stability of a pocket spring mattress. This is comparable between the two brands.
Durability & Longevity
Ecosa's 15-year warranty suggests confidence in long-term durability. Koala's 10-year warranty is still competitive. In real-world terms, both should last 8–10 years of nightly use before noticeable sagging occurs, provided you rotate regularly.
Price & Value for Money
At roughly $100 difference (Queen size), the pricing is virtually identical. The real value question is whether Ecosa's adjustable firmness and extended warranty justify the slightly lower upfront price, or whether Koala's superior cooling and longer trial period deliver better value for your situation. Both offer competitive pricing for Australian-made foam mattresses.
Final Verdict by Use Case
Couples with different preferences: Ecosa wins. You can adjust layers without compromise.
Hot sleepers: Koala wins. Kloudcell is demonstrably cooler.
Budget-conscious: Ecosa by a small margin (slightly lower price).
Indecisive buyers: Ecosa wins. The adjustable system removes firmness risk.
Side sleepers: Either works well; choose based on cooling needs and trial length preference.
