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

Emma vs Sleeping Duck

Both are spring hybrids. Sleeping Duck is the more configurable mattress by a wide margin — medium, firm, or a different firmness on each side, changed by swapping foam pads at home for free — and it scores highest here on both comfort and features. Emma cannot be adjusted at all, but it is cheaper to get into, has the longest trial on this list where Sleeping Duck has the shortest, and does not restrict which bed base you put it on.

The differences that matter

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

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, where three rivals name one

Sleeping Duck

Pros

  • Each side can be a different firmness, and a half-half queen costs the same $1,649 as a single-firmness one
  • Firmness is changed by swapping foam pads at home — free and unlimited during the 100 nights, in soft, medium, firm or extra firm
  • The cover and both foam layers lift out and can be replaced individually, so one worn part does not mean a new mattress
  • A perimeter zone of high-strength steel springs, so the edge holds when you sit on it

Cons

  • A queen is $1,649 — $290 more than Emma and $650 more than Koala
  • A 100-night guarantee, the same as Ecosa and shorter than Newentor, Koala, Origin, Onebed and Emma; returns are capped at two mattresses per household
  • Putting it on a sprung or adjustable base voids the 10-year warranty, as do slats more than 12 cm apart
  • The warranty sets a 140 kg limit per sleeper and only counts sagging deeper than 30 mm as a defect
