The Best Super King Mattress Brands in Australia (2023)

We rate this Ecosa super king as the best super king mattress brand in Australia for two reasons: it’s the only high-quality memory foam mattress in a box brand that comes in super king and it’s one of the most cost effective super king mattresses.

Ecosa is well-known in Australia for being one of the best mattress in a box products and comes in 7 sizes. Just like the standard Ecosa mattresses, the super king can be customised to create a medium, medium-firm or firm fee by unzipping the outer covers and rearranging the foam layers.

This means whatever your sleeping preference and ideal mattress firmness, you can customise the super king Ecosa to suit your needs. Meanwhile, it comes with a removable and washable cover, as well as a waterproof ‘inner cover’ and a 100 night trial for peace of mind.

Despite being one of the few retailers of a super king mattress, it’s hard to ignore the Sleep Republic offering. Using a modern pocket spring system with over 1,850 springs, the Sleep Republic mattress has more than double the amount of pocket springs than a typical pocket spring mattress. A high spring count helps reduce partner disturbance (which is already minimal with a super king bed), and increases comfort.

Coming in at a very budget friendly price and with a 100 night trial, there’s no reason not to give this super king mattress a go.

Dusk&Dawn has three mattresses, all coming in the super king size. The Premier is its middle-range option. The Dusk&Dawn Premier – in Goldilock’s words, is “just right”. While on the higher price side, it’s well worth the splurge thanks to its quality and incredible comfort.

With a top comfort layer comprise of ‘Comfort-Stretch Premium Fabric’, a Dusk-Air Tech layer, a layer of Elasta-Gel, and premium comfort foams, all these comfort layers sit over ‘ISO Coil’ 5 Zone Pocket Spring System for increase comfort and reduced partner disturbance.

Allay Nature Firm is an Australian-made mattress and brand which can be purchased via the Chiropedic website or at any Victorian retail store. It’s hypoallergenic and eco-friendly. It can be purchased in a medium or soft feel too, and we’d rate the firm mattress an 8.5/10.

With a natural bamboo fabric that is soft to touch but extremely durable, the natural properties of the bamboo fabric make it anti-microbial and extremely breathable keeping your sleep surface fresh and healthy. A layer of wool blend is specially quilted under the fabric which is a natural insulator, keeping you cool in summer and warm in winter, allowing for year round comfort.

The support system of the Allay Nature Firm is a strong high gauge indie coil pocket spring system which is zoned in 5 places to provide maximum support for the head, back and feet and gentle pressure relief for the shoulders & knees.

Finally we come to the Yinhala Classic Comfort mattress. While the most premium priced on this list, if you’re after a high-quality hybrid super king mattress, this one’s hard to beat.

With a breathable, elastin fabric cover that sits over a range of quality comfort foams, which sit over 9 zone ultra coil pocket spring systems, we’d say most sleepers will find this mattress extremely comfortable and supportive. Enmeshed with the foam comfort layers is a sheet of our proprietary Cloud Gel, which is 76% more breathable than standard foam, and induces a cool night’s sleep in seconds.

This mattress can be ordered online and comes with a 100 night trial for peace of mind in case it’s not the right fit for you.
