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

Onebed vs TEMPUR

Both are all-foam. Onebed is thicker, much cheaper to get into, switches between two firmness settings, runs a 125-night trial with no minimum stay, and covers sagging from 20 mm. TEMPUR is medium only, 20 cm deep, and has no trial at all — its case rests on TEMPUR's own material and a warranty stated as full replacement rather than pro-rata.

Pros and cons, side by side

Onebed

Pros

  • The 125-night trial has no minimum stay — you can return it in week one
  • Sagging is covered from 20 mm — a shallow threshold, and one Onebed actually publishes
  • Firmness changes by unzipping the cover and flipping the top layers, not by moving the whole mattress
  • Carries both OEKO-TEX and CertiPUR-US certification

Cons

  • All-foam, so there is no spring layer for edge support or airflow
  • Free delivery carries an asterisk — the site says it may not be available for some rural and remote areas, without saying what it costs instead
  • Only two firmness settings — medium and medium-firm, with nothing firmer
  • The instalment amounts are shown but the provider is never named

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
