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.

SupportTo help create an ideal foundation for sleeping, 3 targeted high-density precision cut support zones are designed to take the pressure off. No matter what position you prefer, overall it helps make a better sleeping experience.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.

FAQs

Koala

Why does my Koala mattress smell?

The smell you're noticing from your new Koala mattress is likely due to off-gassing, a common occurrence with new products made from certain materials, including polyurethane foam. Off-gassing refers to the release of volatile organic compounds (VOCs) into the air, and it can result in a unique, often chemical-like smell. This process is generally harmless, and the odor usually disappears on its own within a few hours to a couple of weeks after unboxing. To help speed up the process, you can air out the mattress or place it in a well-ventilated area. However, if the smell persists or causes discomfort, it's recommended to reach out to the manufacturer for assistance.

Can I wash my Koala mattress cover?

Yes, you can wash your Koala mattress cover. It is designed with a removable feature that allows you to unzip it from the mattress. For cleaning, you can place the cover in your washing machine on a cold cycle. After washing, it's best to let it air dry. If you notice any light stains, you can spot clean those using a mild detergent and a soft cloth. Remember, for stubborn stains or extensive cleaning, it might be best to consult with the manufacturer or a professional cleaning service to avoid potential damage.

Can Koala mattress be flipped?

The Koala mattress is designed with a unique feature: it has two flippable layers within the mattress that allow you to adjust the firmness to your liking. These layers are found under the breathable TENCELยฎ Lyocell Cover, which encases the flippable comfort layer. To adjust the firmness, you simply unzip the mattress cover and flip the double-sided Kloudcellยฎ mattress topper. This feature allows you to customize the feel of your mattress without having to flip the entire mattress, which is not designed to be flipped as the support base layer is not meant for sleeping directly on. Despite this ability to customize firmness, it's still recommended to rotate the mattress head-to-foot regularly to ensure even wear and longevity.

Sleeping Duck

Where is Sleeping Duck mattress made?

Sleeping Duck mattresses are assembled in China, with materials sourced from multiple locations. The foam components of the mattress are produced in Sydney, Australia, while the springs and upholstery layers are manufactured in China. Thus, while some aspects of production take place in Australia, the final assembly occurs in China. To then be shipped back to Aus for sale.

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?

Yes, Sleeping Duck mattresses are non-toxic. The company ensures this by using foams that hold the highest Global Green Tag certification, a certification system that guarantees products are environmentally sustainable and non-toxic. While the mattresses might have a smell when first unboxed, this is normal and non-toxic. However, it's important to note that the AntiGravity Foam used in the mattresses cannot be washed as it begins to disintegrate when exposed to water. If needed, the company recommends replacing this layer.
