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.

Pros and cons, side by side

Emma

Pros

  • A 150-night trial — 30 nights more than Newentor, Origin or Koala, 50 more than Ecosa
  • A foam frame around the springs, so the edge holds when you sit on it
  • Cooling is built into all three layers: graphite foam, a polyethylene-blend cover and an open spring core
  • Seven support zones across the length of the bed

Cons

  • Medium-soft is the only firmness Emma makes, so there is no firmer version to switch to
  • Free delivery and returns cover select metro addresses only; outer and regional areas pay a fee
  • Delivery fees are not refunded if you return it inside the trial
  • No foam or textile certification is published

Sealy

Pros

  • Four walls of UniCased XT edge reinforcement, specified by the maker rather than left unstated
  • Four firmness levels at the same price, so choosing the feel costs nothing
  • Stocked in Harvey Norman stores, so you can lie on it before you buy
  • Made in Australia, which Sealy states on the product page

Cons

  • A queen is $3,699
  • No sleep trial, so the showroom is the only chance to test it
  • Sealy does not sell direct; you buy through Harvey Norman
  • The Rosewood build is a Harvey Norman exclusive, so you cannot price-compare it elsewhere
