Sleeping Duck Mattress Medium King Questions & Answers
Verified🏆 2026www.sleepingduck.comMPN: SDMAT-KNG-MEDHi, We’ve had our medium duck for 2 1/2 weeks now. I get up in the morning with a very stiff, sore back, so I don’t know whether it’s too hard or too soft. Where do I go from here? I bought it in the hope it would improve my back but it has made it a lot worse. Can you give me some advice please. Regards, Jill
I’d reach out to SD and ask their advice, they provide excellent customer service When I get a sore back I head to my phsyo who treats the acuteness and provides mobility exercises to get the region working better. This works for me
Hi Jill. What firmness of mattress did you get? I have the medium, which is perfect for me. My brother started with the firm and changed it for the medium and was much happier. He said the firm was brutal.
We're here to help, Jill! Although everyone's preference may differ, we do have some suggestions that will hopefully have you sleeping comfortably. With that in mind, feel free to give us a call on 1800 667 196 (Mon-Fri, 9am-6pm AEST) as the team would love to discuss.

hi we are looking at a Sleepduck king mattress SD Mach II. We have an existing slat base. Does this make any difference to the performance or comfort of your mattress? Regards John
We have a slat bed as well worked well for us
Thanks Brent.
Hi John, Thanks for your interest in the Duck! We're all about ensuring your Mattress is well supported so you can receive the best comfort and support for years to come. As Brent's mentioned, a slatted base is absolutely suitable for our Duck. We recommend the slats be no further than 12cm apart, just to ensure each spring is well supported.
You can take a closer look at these recommendations on our website here: external link

Hi we are really keen on a SD mattress however would like a king gaslift frame that's wipeable not fabric any recommendations
Hi Angela, Thanks a bunch for your interest in the Duck! We'd love to help get you sorted with your dream setup. For our King size, we recommend a firm flat surface or a slatted base. If the base is slatted we recommend the slats be no further than 8 -12cm apart. In addition, we'd also recommend two central supporting beams along with two grounding legs on each.
These recommendations will ensure the Duck gets the best support to go the distance. You can check them all out on our website: external link
While we don't offer a gas lift frame in our own range, our team are happy to help with any suggestions and our bed base recommendations if you'd like to give us a bell at info@sleepingduck.com.
Warm regards, SDHQ
Question 1: Would a bamboo waterproof mattress protector impact the comfort of the foam layer? Will the waterproof layer restrict the foam from compressing properly when I lay on it? I can see both waterproof and non-waterproof bamboo mattress protectors for sale, but not sure if it will make a difference with how the mattress works.
Question 2: The mattress already has a bamboo top layer. Do I still need a mattress protector?
Hi Michelle, Thanks for getting in touch, we really appreciate it! Our top cover isn't waterproof, so we would always recommend using a protector to increase the longevity of your Duck. If you would like to use a mattress protector we would recommend mattress protectors that are from light and breathable materials such as Cotton, Tencel, Bamboo. These usually won't change the feel of the mattress.
A great one we have found is a brand called "In Your Dreams". This is a bamboo mattress protector that fits the Duck and can be found at Spotlight or online.

We would like to purchase a super king mattress from you and want to know the next step? Email address is Christinabatsoukas@live.com.au
Thanks for the question Christina. We have also sent you an e-mail, but we'll outline it here as well! Unfortunately we don't currently produce a Super King Sleeping Duck mattress. Due to machinery limitations we can only make our Ducks in traditional Australian sizes from Single up to King. Additionally, because our mattresses are pre-made in these standard Australian sizes with designated levels of firmness built in, we are also unable to offer custom sizing.
For those looking to get their hands on a Duck you have the option of placing your order via our website (sleepingduck.com), and by giving us a call on 1800 667 196.
If you were to purchase over the phone you would be able to pay via card (we accept Visa, Mastercard, American Express). If you were to order online, payment could be processed via card, PayPal, or an online financing option through ZipMoney.
Kind regards, Team Sleeping Duck
How long does the smell last for. Ive had mine for 2 weeks and it still smells
We purchased a new mattress, feather doona, underlay and sheets. There is a new smell still but i dont mind it. Dont know which one of these still has the new smell.
Hi Tracey, Thanks for getting in touch, we really appreciate it. Our Sleeping Duck foam used in the mattress is polyurethane, and is expanded using pressure. The foams are also GECA approved and have been tested by their standards to show no detectable VOCs. You can find more information about GECA at external link .
When opened our mattress will have a bit of an initial smell as it has been vacuum sealed for transport and you can liken this to a new car smell - the severity of which can depend on how sensitive you are to smell. This is non-toxic.
If you're finding that the smell in the mattress is lingering we often suggest taking out the foams during the day and standing them against a wall in a ventilated room. I would also suggest changing sheets often as they can absorb the smell and cause it to linger.
If there's anything else our team can help you with, please don't hesitate to ask.
Kindest Regards, Team Sleeping Duck :)
Thank you. Ill follow your advice and air the foam
Can I see one and in Western Australia
Can you use a phone?
Hi John, Thank you for your question! Unfortunately at this point in time we do not have any showroom locations in Western Australia, only in Melbourne and Sydney. We do offer a 100 night guarantee on all our mattresses. This way you can try it in the comfort of your own home, night after night! Firmness swaps within your 100 night trial are free of charge, so you can't lose with whichever firmness you choose.
Please don't hesitate to get in touch if there is anything else we can assist with.
Kind Regards, Team Sleeping Duck
