Comfort	Appreciating that everyone is different, Sleeping Duck allows you to choose from a medium or firm mattress (or half-half on Queen and King sizes). Over the course of your 100 night trial you can change the firmness of your mattress depending on the way you are sleeping. These firmnesses can be adjusted with just the pull of a zip. The ComponentAdapt customisation system empowers you to take full control of the comfort of your mattress. This is achieved via interchangeable Precision Pads that you can swap out for both you and your partner. After sleeping on your mattress, you can contact the SDHQ who can help you to customise and adapt the mattress with up to 256 combinations possible.	Our unique double pocket spring layer acts as a great source of ventilation. The open structure allows air to circulate freely thus providing a cooler sleep. In contrast, a full block of foam acts as a barrier to ventilation and traps heat in it. This makes the mattress hot, especially during the Australian summer! Memory Foam infused with millions of gel beads to maintain perfect temperature through the night, this material adapts to your body to redistribute heat and offer pressure relief. Eva's latex open cell and pinhole structure allows it to flex and breathe.
Support	The Sleeping Duck Mach II has a multi-zone support structure to make sure every part of your body is wonderfully supported and comfortable. Pocket Springs are far more resilient and provide better support over a longer period of time. They're specifically designed to ease the human body to relaxation and relieve pressure points by varying the distribution of weight throughout the entire surface. The mattress has superior edge support thanks to the reinforced spring perimeter through the use of 2.3mm springs on the entire border. This allows you to sleep edge-to-edge, making your Queen size feel like a King, and allowing you to sit or sleep on the edge without the rolling or sliding off feeling. Independently pocketed springs create zero disturbance between you and your sleeping partner.	Our unique combination of micro and pocket springs provide support where it matters. Our 5 zone pocket springs provide optimal support from head to toe ensuring the body is properly aligned, no matter the sleeping position. The springs at the edges are also developed with thicker premium grade spring, eliminating the feeling of falling off. The micro springs bring an additional support layer closer to the surface, providing an extra bouncy feeling when sleeping on it. The patented Micro Springs technology creates air flow through the mattress, relieves pressure wherever it's most present during sleep and lends support as close to the body's contours as possible. Superior Edge Support: supported by robust springs along its side pockets, an Eva mattress makes it near-impossible to fall out of bed or sink down when banished to the mattress's edge by your partner, cat or sleeping habits. This side-spring technology encourages sleepers to utilise and enjoy the mattress's full, lush and sprawling surface.

Where is Sleeping Duck mattress made?

Sleeping Duck mattresses are assembled in China, with materials sourced from multiple locations.

Who is the founder of Sleeping Duck?

Sleeping Duck was founded by engineers Winston Wijeyeratne and Selvam Sinnappan in 2014. Based in Melbourne, they were motivated to create their own bed after finding the existing process of buying a bed to be expensive, complicated, and frustrating. Selvam Sinnappan currently serves as a Founder and Director of the company. Their mission was to simplify the mattress buying process and provide high-quality, tailored sleep experiences to their customers.

Is Sleeping Duck non toxic?

Can you flip an EVA mattress?

No, the Eva mattress is not designed to be flipped. It is a one-sided mattress, meaning that the comfort layers are only intended to be used on one side. The mattress is constructed in a way that the top side is optimized for comfort and support, while the bottom side is typically a non-slip surface that helps keep the mattress in place on the bed frame. It is recommended to rotate the mattress occasionally to promote even wear, but flipping it over is not necessary or recommended for maintaining its intended comfort and support.

How long does it take for Eva mattress to inflate?

Most memory foam or hybrid mattresses, like the Eva mattress, take about 24-72 hours to fully inflate after being unpacked from their compressed packaging. It's usually okay to sleep on them after a few hours, although this can depend on the brand's specific instructions and environmental factors such as temperature and humidity.
