FAQs

Zinus iCoil

Is Zinus non toxic?

Yes, Zinus mattresses are considered safe and non-toxic. They are certified by CertiPUR-USยฎ, which means the foam used in the mattresses is tested to meet specific criteria for indoor emissions, content and physical performance. It signifies that the foam does not contain harmful substances such as formaldehyde. Therefore, Zinus mattresses are not classified as dangerous.

Can I remove my Zinus mattress cover?

No, you should not attempt to remove the cover of your Zinus mattress, as it does not have a zipper and is not designed to be taken off. This cover functions in conjunction with the mattress itself and removing it may compromise the fire safety barrier and could potentially void the warranty. It's worth noting that the cover is not washable, so if necessary, you should spot clean it in place.

Is Zinus a Chinese brand?

Yes, Zinus is a global brand with origins in South Korea, founded by Youn Jae Lee in 1979. However, all of Zinus mattresses are currently manufactured in Xiamen, China. The company originally started with making outdoor tents before evolving into an industry leader in the mattress and furniture market.

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.
