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 gives you the longer trial; Ecosa answers with a longer warranty. Neither has a spring layer, so both run warmer than a spring hybrid.

Ecosa vs Koala in practice

Three settings or two

Ecosa changes from the inside. You unzip the cover and reorder three foam layers to get three settings, and the Original and Plush editions cost the same. Koala changes by turning over: one side is medium-firm, the other firm, and there is nothing to unzip.

What the foam is

Ecosa is G-7 memory foam and does not claim zoned support. Koala has a 7 cm Kloudcell comfort layer over 3-zone high-density support foam. Both are 25 cm deep and score high for motion isolation. Neither has springs, so both sleep warmer than a spring hybrid.

Trial, warranty and cover

Koala's trial runs 120 nights and Ecosa's runs 100, both with free returns. Ecosa's warranty runs 15 years to Koala's 10. Ecosa also uses a woven silica sock as its fire barrier instead of a chemical flame retardant, and its TENCEL cover zips off for washing.

Final recommendation: Which one is right for you?

These two suit different sleepers. Use the criteria below to match your body type, sleeping position and temperature needs to the right choice.

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 longer trial, and flipping the whole mattress is change enough.
