FAQs

Koala Soul Mate

Is Koala Soul Mate good for hot sleepers?

The Koala Soul Mate mattress seems to be designed with features that can benefit hot sleepers. One notable feature is its Adaptive Foam Springs, which allow for better airflow through the mattress. Enhanced airflow can help dissipate heat and promote a cooler sleep environment. Additionally, the mattress may have other cooling technologies or materials, although the specifics would depend on the most recent product design. However, individual experiences can vary, so it's important to consider personal preferences and other factors such as local climate, bedding, and personal metabolism.

Is the Koala Soul Mate bouncy?

The Koala Soul Mate mattress has a balance of motion isolation and some degree of bounce, thanks to the Adaptive Foam Springs. While Koala mattresses are generally known for their excellent motion isolation, which reduces bounce and disturbance from movement, the inclusion of these foam springs in the Soul Mate model does impart a certain amount of bounce. This balance ensures you get the responsiveness for ease of movement or changing positions, while still maintaining the ability to minimize motion transfer for undisturbed sleep.

Do Koala mattresses have springs?

Yes, the Koala Soul Mate mattress does include a unique feature: Adaptive Foam Springs. These aren't your traditional metal springs, but rather springs made of foam. They are designed to adapt to your body's slightest movements, providing tailored support. This design incorporates Koala's Zero Disturbanceยฎ technology, meaning that movement on one side of the bed doesn't disturb the other side. The spaces between these foam springs enhance airflow, contributing to a cooler night's sleep. This innovative use of foam springs is unique among mattresses available in Australia.

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.
