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.

Emma vs Koala in practice

Springs or foam

Emma Luxe ViscoCool is a 26 cm hybrid, with 7-zone pocket springs inside a reinforced foam frame, under ThermoSync graphite foam and a PolarLuxe cover. Koala is 25 cm of foam: a 7 cm Kloudcell comfort layer over 3-zone support foam. Emma scores higher for cooling and edge support. Koala scores higher for motion isolation.

One feel or two

Emma makes the Luxe ViscoCool in medium-soft only, so there is no firmer version to move to. Koala flips between medium-firm and firm. If you already know you like a softer bed, Emma is the closer match; if you are unsure, Koala gives you two feels in one mattress.

Trial, delivery and payment

Emma gives you 150 nights to decide, against Koala's 120. Emma's free delivery and returns cover select metro addresses only, though, and the delivery fee is not refunded if the mattress goes back. Koala's trial includes free returns and its delivery is free, with exclusions. Both carry 10-year warranties, and Emma offers Afterpay and Zip at 0% interest.

Koala

Pros

  • Only five sizes — no Long Single or Super King
