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

Sealy vs TEMPUR

These two share the lowest overall scores on this list, and for the same underlying reason: neither gives you a way out. Sealy has no sleep trial and is sold through a retailer; TEMPUR has no sleep trial either. Beyond that they are opposites — Sealy is the thickest mattress here, an innerspring with four firmness levels and specified edge reinforcement, while TEMPUR is the thinnest, all-foam, medium only, and considerably cheaper.

The differences that matter

Sealy compared with TEMPUR
Specification Sealy TEMPUR
Entry price From $2,399 From $1,799 (better of the two)
Warranty 10 years 10 years (full replacement)
Overall score 8.4 8.5 (better of the two)
Firmness Four levels — Firm / Medium / Plush / Ultra Plush Medium
Construction Innerspring 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.

Which one is for you

Choose Sealy if…

You can get to a showroom, want a specific firmness out of four, and want a substantial innerspring.

Pros and cons, side by side

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 — around three times Ecosa and six times Newentor
  • 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

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
