Sleeping Duck Mattress Review

Unfortunately the Sleeping Duck mattress is no longer available in the UK. Don’t worry, you can read my other mattress review here.

It’s been a while since I last wrote a review so today I am quite happy writing this Sleeping Duck mattress review. This company was founded in Australia (2014) by two engineers that had difficulty finding a good mattress. They decided  that the only way to do it was to make one themselves. This is how Sleeping Duck was founded. They later launched in 3 more territories and they have seen a great success.

The mattress arrived in my place almost a month ago and the first thing I noticed about it is its weight. It is really heavy! It is a rolled mattress so it comes in a carton box. The interesting part about this mattress is its modular design. That means that you can change the firmness according to your needs. The mattress is available in two firmness levels, medium and firm. However, if you are not happy with your choice then you can request a firmness swap! At this point two more options become available to you, soft and extra firm. So in total you have 4 options. You can also buy a half/half mattress and go for different firmness levels if you and your partner have different needs.

In order to change the firmness of your mattress all you have to do is swap the foam layers. For this review, I received both the medium and firm options so I will talk about them separately. It’s time now to move to the full review below.


I have already mentioned that the Sleeping Duck mattress is very heavy. It’s also very thick measuring 31cm in height. It is made of a total of 3 layers plus the cover. In detail the layers are:

  • A dual layer which is made of both Latex and Memory foam. It provides your body with pressure relief and support. It also keeps the mattress cool during the night.
  • A high density polyfoam layer which is the one that determines the firmness of your mattress. It provides you with comfort and support.
  • A 5zone pocket springs layer which provides your body with support but also keeps the mattress together and it’s essentially its base.

You can have a look at the image below to get a good idea of how the Sleeping Duck mattress is designed.

The cover of this mattress is an interesting one. It is made of two materials, bamboo and polyester. The top white part is made of bamboo which is a material with great benefits. Firstly, it’s naturally anti-microbial and it’s a very breathable. It’s not a coincidence that it is used to make premium underwear. For those who care about the enviroment, it’s a very eco-friendly material as it needs three times less water compared to cotton. The side parts of the cover feature a dark grey colour and the polyester used there is a very strong material. This is for practical reasons as the modular design needs a cover that can keep all the layers together.

On the side there is a zip for you to use when you want to swap the foam layers but unfortunately the cover is not machine washable. You can only spot clean it but make sure you let it dry properly before you put the sheets on. The design of the cover is not the best I have seen and personally I think it lacks imagination. It’s very industrial and it’s quite simple. Of course, we don’t see the cover often so I can live with that. In general I loved the use of bamboo but I didn’t like the fact that you cannot machine wash it. But this is the price you pay when you get premium materials; they need extra care.


Sleeping Duck didn’t go for the one mattress-fits-all approach. They decided to create different firmness levels. For the purpose of this review I received both the medium and the hard option so I will talk seperately about each one.


The medium set-up was the first I tested. I am a relatively small person so I usually prefer the medium firm mattresses. This set up is a 3.2 in firmness on a scale from 0-5 with 5 being really firm. It’s quite similar with the Simba mattress and I found it working really well for me.

I will now talk about the different sleeping positions like usual. Starting from the back one, the mattress reacted quickly and the memory foam hugged my back and hips. I felt well supported and my spine was well aligned. Moving to the side position, sinkage increased but it was the right amount to keep my spine straight. I felt the springs working more than the memory foam but the side position is all about proper sinkage and Sleeping Duck did a good job here. Turning to the stomach position I felt well supported and my hips remained in a good position. It was very comfortable and I think this set up worked well for my body type. Finally, testing the edge support, I felt that the mattress was really solid and you get a good performance even on the corners.


The hard set-up was the second one that I tried. In terms of the firmness level, I would say it’s a 3.8 with 5 being really firm. This Sleeping Duck mattress is definitely the firmest one I have tried.

I will now talk about the different sleeping positions. Starting from the back position I felt the mattress hugging me but not as much as the medium set up. This is normal obviously. I felt well supported though and it was comfortable to sleep this way. Turning on the side, I felt that the sinkage was not enough for my hips to get in the right position and it felt not so comfortable being in this position. Having said that, my husband who is heavier than me preferred the hard set-up. So it’s definitely relevant to your weight. Finally, going to the stomach position, I felt that my spine was aligned properly and I got the support head to toes. Overall, I prefered the medium set up but for people with more weight and maybe back problems the hard option is probably better.


I have mentioned already that the Sleeping Duck mattress is a rolled one. It comes directly to your door in a box but make sure you have someone else in the house to help you with that as it’s very heavy. My mattress came after 3 business days and there was no charge for the delivery. During check out you can only choose a weekday (Mon-Fri) but if you want a Saturday delivery you should email them and they will sort everything for you. It would be easier if there was an option on their site but it’s not that hard to email them. I am glad they offer the Saturday delivery so no complaints here.


The matress comes with a 100 night trial period. If you don’t like your mattress you can return it for free and you will get a full refund. You just need to email their customer service team and they will arrange everything for you. In terms of guarantee, they offer a 10 year one which is great! Make sure you read carefully what is included so you don’t get an unpleasant surprise. Overall, Sleeping Duck offer a great package and I was really happy with the whole experience.


Finishing this Sleeping Duck mattress review I would like to share my final thoughts with you. It is a very good mattress overall with an interesting modular design that comes with different firmness levels. It features some cool materials like bamboo but it does come with a cover that is not machine washable. This is the only downside really. If you suffer from back pain then the Sleeping Duck mattress should be very high on your list, especially the hard set-up! So if you look for a high quality hybrid mattress paired with great service then this is a great choice for you!
