FAQs

Sleep Republic

Is Sleep Republic mattress firm?

The Sleep Republic mattress is considered medium to firm on the firmness scale, catering primarily to stomach and back sleepers who often require more support to maintain healthy spinal alignment. However, some side sleepers might find this mattress too firm, as they generally need a softer surface to cushion the shoulder and hip areas. As always, firmness can be subjective, and personal comfort depends on factors such as individual body weight, sleep position, and personal preference.

Can I can return 2 mattresses under the 100-night trial?

Please Be Aware! Yes, there is a limit to the number of mattresses you can return under the 100-night trial. The policy restricts returns to one item per order, per household. If you're considering purchasing more than one mattress, it's recommended that you first buy one, try it out, and if you're satisfied with the product, then proceed to place an additional order. This approach helps ensure that you are completely happy with your purchase before making a larger investment.

How do I return my mattress and get a refund?

It's a hassle to return your Sleep Republic mattress, unlike other brands. You can do it within the 100-night trial period, you need to wait for at least 14 days from the purchase date. If you still aren't satisfied between the 15th and 100th day, you can contact Sleep Republic via email at info@sleeprepublic.com.au, stating your intent to return. Remember to include a photo verifying the mattress's condition.

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.
