    As Seen In

    The Science Inside Australia's Comfiest Mattress

    Adaptive Comfort Technology™

    Our 7cm thick top layer cradles and supports your body’s natural alignment giving you a highly comfortable ‘ache-free’ sleep. This supportive layer means zero partner disturbance while you sleep, no matter how much they move.

    Intellicool Technology™

    Revolutionary Australian made technology allows greater breathability and superior airflow through its unique cell structure. This dissipates excess body heat when it’s hot, providing a cool and comfortable sleeping environment.

    Breathable Tencel® cover

    Made from environmentally responsible and sustainably sourced materials. Your stretch knit Tencel® is super soft, moisture-wicking and highly breathable.

    Australia's comfiest mattress

    We built The Delta Sleep Mattress based on Australians preferred firmness for maximum comfort.

    We also looked at our competitor’s common downfalls such as sagging (the cause of spine, neck and hip pain) and engineered our mattress to be 100% sag-free.

    We’re confident we have the cosiest mattress on the market which is why you can try your mattress risk-free for 120-days.

    The perfect temperature

    Studies show sleeping in a hot environment makes it harder to drift off and reduces the amount of restful deep sleep you achieve.

    Most mattresses can’t handle brutally hot Aussie summers.

    Our Intellicool technology™ keeps you cool in summer and gives you the perfect amount of warmth in winter — for a blissful nights sleep.

    Don’t love it? We’ll refund every cent you paid and collect the mattress — no hidden fees, catches or shipping costs.

    No, it is a full foam mattress

    Is it anti-bacterial?

    We use Ultra Fresh - an antimicrobial protection in our foams. It is applied to our foams to help inhibit and destroy bacteria growth and, in turn, ensure a healthier and more hygienic sleeping environment, particularly for asthma or allergy sufferers

    The foam used in our Delta Sleep Mattress are 100% recyclable and have been approved by the GECA (Good Environmental Choice Australia).

    Where are the mattresses manufactured?

    VIC Australia

    Do you make the mattresses or work with an external company?

    Can the mattresses be flipped?

    No, they are only single sided

    Is the cover removable?

    Yes, our cover has been designed to allow easy washing. Simply unzip it from your mattress and pop it in the wash on a delicate cycle.

    What is the best process for washing the mattress?

    Can be spot cleaned with soap and water while on a mattress or remove the cover and wash on a gentle cycle

    Are there any recommended bases or frames for the mattress to be used in conjunction with?

    The bonus of our mattress is it can be used with most types of bases and frames. No need to buy a new one!

    Is the base included or should you have your own base already?

    A base is not included with the Delta Sleep Mattress. You should have your own base already, if not, all bases and frames are suitable.

    Can these mattresses be used with an adjustable bed?

    Our Delta Sleep Mattress is designed with a solid core for maximum comfort. This means it is not designed to bend, meaning it is not suitable with an adjustable bed.
