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 Onebed

Both are all-foam, both change firmness by unzipping the cover rather than by returning anything, and both sit in the same part of the price range. Ecosa offers three settings to Onebed's two. Onebed offers the longer trial with no minimum stay — you can send it back in week one — and covers sagging from a shallower depth than anything else here, which is the part of a warranty that actually gets claimed.

The differences that matter

Ecosa compared with Onebed
Specification Ecosa Onebed
Entry price From $870 From $795 (better of the two)
Sleep trial 100 nights 125 nights (better of the two)
Warranty 15 years (better of the two) 10 years
Overall score 8.9 9.3 (better of the two)
Firmness Adjustable — 3 settings (Original / Plush) Adjustable — Medium / Medium-firm
Construction Memory foam All-foam (Memory Foam + Auralux)

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 want the third firmness setting, or the longer warranty term.

Check Ecosa price

Choose Onebed if…

You want to be able to return it immediately if it is wrong, and you care more about how the warranty defines a fault than how many years it runs.

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

Onebed

Pros

  • The 125-night trial has no minimum stay — you can return it in week one
  • Sagging is covered from 20 mm — a shallow threshold, and one Onebed actually publishes
  • Firmness changes by unzipping the cover and flipping the top layers, not by moving the whole mattress
  • Carries both OEKO-TEX and CertiPUR-US certification

Cons

  • All-foam, so there is no spring layer for edge support or airflow
  • Free delivery carries an asterisk — the site says it may not be available for some rural and remote areas, without saying what it costs instead
  • Only two firmness settings — medium and medium-firm, with nothing firmer
  • The instalment amounts are shown but the provider is never named
