We earn advertising and referral fees from many of the brands we rank, and those fees affect where they appear.

Top3 Mattress compares mattresses sold in Australia, and we make our money when a reader buys through one of our links. Brands pay us advertising and referral fees, and those arrangements affect which mattresses we cover and how high they sit in our rankings. Some mattresses here have no arrangement with us at all.

Every mattress is scored against the same ten published criteria, and each of the ten scores is shown alongside the total. What those criteria measure, and how the total is set, are laid out on our How we rate page. The work behind the scores is desk work: we read published specifications, warranty documents and trial terms, and cross-check them against each manufacturer's own pages. We do not buy these mattresses and sleep on them, and no score here comes from in-home testing.

We do not cover every mattress sold in Australia, and the ones we can earn a commission on are more likely to be among the ones we do cover. Prices, trial lengths and warranty terms change without notice, so check the brand's own page before you buy. A ranking here is not a guarantee about a product and not an endorsement of it. Our full terms are set out in the Terms of use.

Head to head

Ecosa vs Koala

Two all-foam mattresses that both let you change firmness without sending anything back, but they do it differently: Ecosa reorders three internal layers for three settings, Koala flips over for two. Koala is the cheaper of the two to get into and includes free returns inside a longer trial; Ecosa answers with a longer warranty. Neither has a spring layer, so both run warmer than the hybrids here.

The differences that matter

Ecosa compared with Koala
Specification Ecosa Koala
Entry price From $870 From $712.00 (better of the two)
Sleep trial 100 nights 120 nights (better of the two)
Warranty 15 years (better of the two) 10 years
Overall score 8.9 9.2 (better of the two)
Firmness Adjustable — 3 settings (Original / Plush) Flippable — Medium-firm / Firm (7/10)
Construction Memory foam All-foam

Firmness and construction are listed as differences, not as a winner — which one suits you depends on how you sleep, not on which is better made.

Which one is for you

Choose Ecosa if…

Three settings beats two for you, or the longer warranty matters more than the shorter trial.

Check Ecosa price

Choose Koala if…

You want the lower entry price and the longer trial, and flipping the whole mattress is change enough.

Pros and cons, side by side

Ecosa

Pros

  • Unzip the cover and reorder three foam layers to change firmness — no return needed
  • Original and Plush editions cost the same, so choosing feel costs nothing
  • A 15-year limited warranty, five years past the standard ten-year term
  • Fire barrier is a woven silica sock rather than a chemical flame retardant

Cons

  • No sale price is running, so the list price is what you pay
  • A 100-night trial, where 120 is the common figure in this category
  • Memory foam with no spring layer, so it sleeps warm
  • No zoned support is claimed

Koala

Pros

  • Flippable firmness — change your mind without sending it back
  • The 120-night trial includes free returns
  • CHOICE Recommended and ProductReview.com.au awards 2023–2025 — given to the Koala range, not to this model alone
  • All-foam build with Zero Disturbance makes it strong for couples

Cons

  • All-foam, so it runs warmer than a spring hybrid
  • Only five sizes — no Long Single or Super King
  • Three support zones where several rivals offer seven
  • At $999.20 for a Queen it sits well above budget boxed rivals
