Eva mattress features a hybrid design that mixes 5 zone pocket springs with latex, gel memory foam, and high-density foam. This makes the mattress thicker, making it easier to get in and out of bed every day with the added bonus of support and pressure relief. The pocket spring design deviates from traditional springs because they supply more airflow while still giving bounce and edge support to the bed. Eva mattresses are medium-firm more towards the firmer side (7-8/10) and preferred by tons of individuals. Eva also donates one mattress to charities and homeless shelters across Australia for every ten mattresses sold.

Sleeping Duck is a mattress in a box company that is based in Australia and has won multiple awards, turned down shark tank investors, plus won Australia’s ‘Best Innovation’ Mattress in a Box for 2019. The quality of Sleeping Duck speaks volumes and matches its achievements. Lately, it’s gone through a significant rebrand and is now called SD Mach II with improved aesthetics, functionality, and a few layer name changes. However, what's excellent is the comfort of the mattress is unchanged, and now it’s more comfortable to interchange the foams, so you get a range of firmness levels. Existing reviews are still certainly valid for this new model.
