Firmness Info

The mattress is a medium/firm feel.

Firmness is the most sensitive and personal element of any mattress. Sleeping Duck have re-engineered the traditional mattress to make it modular, allowing you to pick (and even swap) the firmness that's exactly right for you. Simply choose between medium or firm initially. Rest assured, you'll be able to change the firmness via foam swaps for the first 100 nights for free. Medium: Suitable for side sleepers, Sinks in slightly while being supportive, Approximately a 6/10 on the firmness scale. Firm: Suitable for back sleepers, Still feels cloud like while maintaining a strong level of support, Approximately an 8/10 on the firmness scale. Half Medium & Half Firm:, A different firmness on either side of the bed, Ideal for couples who have different firmness preferences.

Ergonomic Handles
Comfort
3D Spacer Fabric - Our side panels are designed to let air circulate throughout your mattress. Mattresses need to breathe too you know! A top layer of Gel Infused Memory Foam for temperature stability. For the second layer, we chose Natural and renewable Latex, designed to breathe freely yet support uniformly.
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
Dynamic Edge Support - Made of firmer high tensile steel springs, the edge support surrounds the mattress and allows full use of the total surface and for sleeper to lie up to the edge without roll-off. Memory foam for the ultimate in pressure relief and body contouring. Individual pocket springs mean no partner disturbance and a stronger mattress for a longer product life. Specifically zoned in 5 places to provide maximum 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.
