Comfort
Our customisable, double-sided Kloudcell™ comfort layer means you can choose what firmness level works for you. Bamboo charcoal is not only antimicrobial, the perforated memory foam takes the sting out of heat, relieves pressure, promotes airflow, and most importantly it helps you get a better night's sleep.
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.
Support
Designed to work with your body, not against it, our 5 Zoned Adaptive Foam Springs are crafted to react to your body's slightest movements. Each spring offers tailored support without compromising our famous zero disturbance® tech. Plus, with airflow in all the right areas, it’ll help give you a cooler night’s sleep.
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.
