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

Koala vs TEMPUR

Both are all-foam, but Koala is cheaper to get into, thicker, flippable between two firmnesses, and comes with a 120-night trial and free returns. TEMPUR is medium only, the thinnest mattress on this list, and has no sleep trial at all — what it offers instead is TEMPUR's own material at the lowest price TEMPUR sells it, and a warranty stated as full replacement rather than pro-rata.

The differences that matter

Koala compared with TEMPUR
Specification Koala TEMPUR
Entry price From $712.00 (better of the two) From $1,799
Sleep trial 120 nights (better of the two) No sleep trial
Warranty 10 years 10 years (full replacement)
Overall score 9.2 (better of the two) 8.5
Firmness Flippable — Medium-firm / Firm (7/10) Medium
Construction All-foam All-foam (TEMPUR Material)

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.

Pros and cons, side by side

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

TEMPUR

Pros

  • The warranty is stated as full replacement for the whole ten years, not pro-rata
  • TEMPUR’s own material is the reference point for pressure-relieving foam, and this is the cheapest way into it
  • The cover unzips and washes at 30 °C
  • Seven retailers stock it, so you can shop the price rather than take one seller’s number

Cons

  • There is no sleep trial at all — neither TEMPUR nor the retailer offers one
  • Medium is the only feel, so if it is wrong for you there is nothing to switch to
  • At 20 cm there is less comfort layer to work with than in a typical 25–30 cm build
  • The warranty does not publish an indentation depth, so the test a claim is judged against is not stated
