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

Ecosa vs Sleeping Duck

Both are built to be adjusted rather than returned, and both let you keep tuning during the trial. Sleeping Duck goes further than anyone here: each side of the bed can be a different firmness, and swapping the foam pads is free and unlimited. It is also a taller spring hybrid with individually replaceable parts. Ecosa is memory foam, costs less to get into, and carries the longer warranty — but read Sleeping Duck's base rules before you buy, because the wrong bed frame voids its warranty.

The differences that matter

Ecosa compared with Sleeping Duck
Specification Ecosa Sleeping Duck
Entry price From $870 (better of the two) From $999
Sleep trial 100 nights 100 nights
Warranty 15 years (better of the two) 10 years
Overall score 8.9 9.1 (better of the two)
Firmness Adjustable — 3 settings (Original / Plush) Adjustable — Medium / Firm / Half-half
Construction Memory foam Hybrid (Pocket Spring + Foam)

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 Ecosa if…

You sleep alone or you both want the same feel, and you would rather put the money into a longer warranty.

Choose Sleeping Duck if…

You and your partner want different firmnesses in the same bed — nothing else here does that.

Pros and cons, side by side

Ecosa

Pros

  • Unzip the cover and reorder three foam layers to change firmness — no return needed
  • Original and Plush editions cost the same, so choosing feel costs nothing
  • A 15-year limited warranty, five years past the standard ten-year term
  • Fire barrier is a woven silica sock rather than a chemical flame retardant

Cons

  • No sale price is running, so the list price is what you pay
  • A 100-night trial, where 120 is the common figure in this category
  • Memory foam with no spring layer, so it sleeps warm
  • No zoned support is claimed

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
