Read the full Sleeping Duck reviewTop3 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
Sleeping Duck is the most configurable mattress on this list — medium, firm, or split down the middle, changed by swapping foam pads at home, free and unlimited during the trial — and it scores highest here on comfort and features. TEMPUR offers no adjustment, no trial, and the thinnest build here, but does offer TEMPUR's own material and a warranty stated as full replacement for the whole ten years. Check Sleeping Duck's base restrictions before ordering.

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.
You want to tune the feel, or you and your partner want different firmnesses.
