 AI reviews summary 

The Sleeping Duck Mattress is highly regarded for its customisable firmness and its effectiveness in alleviating chronic back, hip, and shoulder pain. The majority of users report a significant improvement in sleep quality and praise the brand's proactive and professional customer service. While immediate satisfaction is exceptionally high, a small segment of long-term owners has raised concerns regarding durability and warranty hurdles after several years of use.

Pros
  • Customisable Firmness: The modular design allows users to swap foam inserts (Soft, Medium, Firm, Extra Firm) even after delivery, with many taking advantage of the "half-and-half" option for partners with different preferences.
  • Pain Relief and Support: Numerous reviewers with pre-existing injuries or chronic conditions report that the mattress successfully eliminated morning stiffness and joint pain.
  • Minimal Motion Transfer: Users frequently note that the mattress effectively isolates movement, preventing partners from being disturbed during the night.
  • Exceptional Customer Service: The support team is consistently praised for proactive communication, hassle-free part exchanges, and efficient delivery/setup services.
Cons
  • Significant Weight: The mattress is noted for being extremely heavy, making it difficult to move, rotate, or lift the corners when changing bed sheets.
  • Long-term Durability Concerns: Several reviewers who have owned the mattress for 3 to 5 years reported issues with sagging or the foam softening, leading to a return of back pain.
  • Warranty Friction: For those experiencing long-term sagging, the warranty process is described as difficult, requiring specific photographic evidence of "visible" dips that may not capture "hidden" foam compression.
  • Delivery and Packaging Hazards: Some users reported delivery issues, including items left in the rain or the delivery box wheels causing scratches on hardwood floors.
Verdict

The Sleeping Duck Mattress is an excellent choice for those seeking a customisable sleep surface and immediate relief from back and joint pain. While it offers a premium experience and industry-leading customer support during the trial period, potential buyers should be mindful of its heavy weight and mixed reports regarding its supportiveness after five years of use.

We bought a mattress and a base, the base is incredibly solid and heavy which has pretty much eliminated partner disturbance for us. After some fine tuning of the foam layer (great, fast after-sales support), it's the most comfortable bed we've ever had. Show details ·  1

leaving soooo much room in the bed. The medium is perfect - not too hard, not too soft. I have also added a super plush mattress protector that I had previously on top so it’s like sleeping on a supportive cloud. Arm and hand numbness is gone and my back feels so much better in the mornings. The only drawback…I don’t want to get out of bed in the morning!

⭐️⭐️⭐️⭐️⭐️ This is our second time purchasing from Sleeping Duck, and once again they have absolutely delivered. The ease of navigating their website and placing an order is seamless.

upgraded both the base/style and mattress from our original purchase, and the entire experience was exceptional from start to finish. Customer service, which has always been second to none, has somehow improved even further. The communication throughout - emails, calls and texts - was proactive, clear and professional. A big shout out to Steph, Zoey and the wider team for their outstanding support.

On delivery day, everything worked like clockwork. From Customer Service coordination to the installation team onsite, it was clear everyone operates in unison. The installation crew were fantastic - positive, capable, professional and even up for a laugh. No issue fazed them.

Despite the challenges of a second-storey delivery and a sloping driveway, the team handled everything effortlessly. Installation took just on an hour, and their workmanship and care were evident throughout. Well presented, well organised and clearly masters of their craft.

Their sheet sets, duvets, and overall quality of their products is amazing, we just bundled everything for ease.

We genuinely cannot fault Sleeping Duck.

We’ll be back again and again.

So just purchased a sleeping duck about a week ago - so fair so good. My husband sleeps on a medium form section and I sleep on the firm. I am a side / stomach sleeper with pre history of lower back issues and it has been great. We had a recent situation where we purchased a mattress from a local shop in April 25 and the previous mattress we had… Read more ·  1

started to develop a dent or valley so to speak after 3-4 months…. The manufacturer is trying to blame on ‘weight distribution’ and it’s not their manufacturer issue… I had neck, shoulder and hip pains from the previous mattress, and since swapping to a sleeping duck, it has done absolutely wonders. I am suffering from shoulder pain atm but that’s not from the sleeping duck, it’s from the previous mattress which unfortunately has been due months of uncomfortable sleeping - tbh I will probably need to seek treatment for it (fyi I’m in my early 30s and active for the most part). In just a week the sleeping duck has been a game changer and honestly it has been incredible - my hip and neck pain is gone!

If you’re on the fence, just do it and don’t wait ! The longer you wait, more time passes which leads you too sleepless and uncomfortable nights. Oh and the other mattress that we purchased from the local shop costed more than the sleeping duck - so it’s honestly a bargain. FYI though the SD in the box is pretty heavy and was a work out taking it up stairs to our room, but it has been totally worth it. Sorry for the rumble but I know for myself who was on the fence for months and literally going through a battle with the other mattress company, and dealing with so much pain and suffering, the Sleeping Duck has completely changed my sleeping experience - thank you SD for creating a product that actually works and not a gimmick!

A way better adjustable mattress that can be cleaned and modified! – We have had a Sleeping Duck SD Mach II mattress for about two months. The whole process from order to delivery to unwrapping was easy and seamless. The mattress is quite heavy to move but is perfectly manageable by two people. The mattress is well constructed, with a removable (zip) cover that can be washed. Underneath this is a blue… Read more ·  1

'anti-gravity' layer (pictured) which appears to be in it's own removable cover (zip2). Beneath that is another removable (zip3) 'ComponentAdapt' cover that contains the precision adjustment pads. Beneath this is the main mattress body which appears to be a non-adjustable unit containing springs. With this construction the mattress can be rotated but not flipped.

Our mattress shipped with two full length precision pads. We chose Medium when we ordered the mattress, but it also came with a 'Firmness Adjustment' offer for 100 days which has allowed us to get smaller precision pads to vary the firmness of the mattress for hips and shoulders on each side. The smaller precision pads for our King size mattress seem to come in either a 1/5 or 1/10 size pad. The 1/5 size pads are currently (Aug24) available in either Soft, Medium, Firm or Extra Firm and the 1/10 size pads in either Medium or Firm. Sleeping Duck encourage you to try each arrangement for 3 weeks which we did. I then spoke to someone at Sleeping Duck who helped me work out how we could adjust the mattress to get a little more support under the hips and a little less under the shoulders. They sent me the precision pads which were easy to install and gave my wife and I our own customised fits. They have since supplied us with a couple of extra pads to fine tune this even further. All at no cost to us. Amazing.

Is it comfortable - for me, yes. I have back and neck issues and rarely sleep through the night and the quality and duration of sleep I get is far better. We recently stayed at a fancy resort with plush beds and I found myself wishing for my Sleeping Duck! I love that I have been able to add extra support under my hips but also to give more softness under my shoulder while still supporting my head. It is far better and cheaper than our previous super expensive Tempur which was too soft in summer and too hard in winter. It is also far better and cheaper than our previous MySide which was awful, collapsed and was not supported by the company who sold it.

So dealing with the company from ordering through to support has all been amazing. So far the mattress which seems really well made has just been getting better and better. It's hard to say how the components will be after 5-6 years but what I do know is that the cover will have been washed and cleaned unlike our old MySide mattress and we can replace individual components inside the mattress (unlike wither mattress) if required. This gives me a very confident feeling that this is the mattress style of the future.

There is a leap of faith, ordering a mattress online without the ability to go to a showroom and try it. Sleeping Duck can't solve that completely but I have been super impressed by the commitment they have shown to making sure the mattress suits us. Thank you Sleeping Duck.

BEWARE OF THE WHEELS ON THE MATTRESS BOX! DAMAGE ++ to floors. I wanted to give 5 stars as love the mattress but the box it came in destroyed some of my hard wood floor. The wheels were misaligned and damaged which caused metal brackets and chipped wheel to scratch the hell out of my hard wood floors. Customer service apologised but no offer of… Read more

any sort of compensation which was disappointing. They referred me to sleeping duck “get ready” email where they suggest to avoid wheels on hard floors. TBH I can’t even remember seeing this when I initially watched video. It would be difficult to avoid wheels on floors given they are screwed into the box. I had to unscrew them to avoid further damage to my floor and stairs when manoeuvrings up the stairs.

Better warning and emphasis on avoiding hard wood floors (perhaps big warning sticker on box or something) would have been helpful- maybe don’t put wheels on full stop…

Otherwise with regards to Mattress, we love it.

Super comfortable. No sagging. I am nearly 80 and have multiple health issues and have found my mattress super comfortable and supportive. No problems with it what so ever. Show details ·  1

 Follow-up  · Delivery and setup were very efficient. No problems with temperature in either summer or winter. The only problem I have is turning the mattress every 3 months but I get my son-in-law to do that when they are visiting. It is still the most comfortable bed I have ever had.

We've had a sleeping duck king size mattress for about 3 years now, and all I can say is DON"T make the same mistake I did, don't buy one! My experience is similar to the other one star reviews and I'd assume the good reviews are from those who have purchased the mattress recently. It's great for the first year, maybe a bit less. I probably would… Read more

have given a good review back then. But after that, and conveniently after to trial period, the mattress deteriorates fast. It begins to sag and you can visually see the sagging when you take off the foam layers.

It has destroyed my back, and my partners back. I wake up in pain most nights and can barely walk. I have seen a physio, but we have to replace this mattress. We have all the different foams, firm, medium, soft, and the little ones you can put together. Nothing changes the issue. But I can see the sagging underneath, so it looks like some of the springs have collapsed.

So, please look at the bad reviews before making this decision. Look at how long the person has had the mattress. Those who have had it less than a year haven't experienced the real poor quality yet.

frame, but we are still astounded at the quality of the mattress. We weren't sure whether we needed a KING!- but Oh Boy- yes it takes up a lot of room, but it's so nice to stretch out! PLUS and I guess this is what most people are interested in, the mattress itself is fabulous. We went with the firm on one side- medium on the other. I like firm, but I was a little unsure if it might be too firm. IT IS PERFECT. My wife likes the medium, and when I lie on it- I think- yeah I could sleep really well on that too! So far we have turned the mattress once and unzipped the top cover to switch the inserts to the other side- all worked as expected. There was a lot of discussion in forums about not being able to lift the corners to put the sheets on??? What- I don't think that at all. I was prepared to do this if it came down to it- however my wife did it easily! I know the mattress is not a 'budget' offering, but in this case you really do get what you pay for. We are very very pleased with the purchase. Thank you.

 Follow-up  · Since my last review we did decide to swap out the medium for another firm (so we are both on the firm). The process was quick and easy and we paid nothing! I cant speak more highly of the actual mattress and the great assistance of the staff.

The Sleeping Duck bed is fantastic, it’s honestly the only bed I’ve found that you can truly customise. I have ongoing back issues, and since sleeping on this bed my pain has been minimal. I’ve tried the medium, firm, and super firm configurations. Medium is perfect for sleeping on my side, while firm works best when I’m on my back. I really love… Read more ·  1

that you can have a half-and-half setup, allowing two different firmness levels in the same bed, it makes such a difference.

I also purchased the side-sleeper pillow, and it’s excellent. It’s the only pillow I’ve used that actually maintains its height, so I don’t wake up with shoulder or neck pain.

On top of that, the customer service is outstanding. I had several questions and requests throughout the process, and every time I received prompt, kind, and helpful responses. This has genuinely been the best customer service experience I’ve ever had, I wish all companies operated like this.

I would absolutely recommend giving the Sleeping Duck bed a try. If you’re looking for real comfort, customisation, and great sleep, this is it.

Overall very pleased with the sleeping duck mattress. They were quick to respond and send out different firmness section when requested, but if you didn't know it was available to ask, I couldn't find that much info on how to customise it to my preference. That being said, I love the mattress so far. I haven't had it during the summer so don't know if it is sleeps 'hot' but it is good now... Definitely getting better sleep. Show details ·  1

We have had our king size mattress for about 8 years now. When we first got it I thought It was a great feature that we could buy a replacement top foam layer to suit our comfort preference. After sleeping on it for a short while we were both happy with the comfort level and didn't need to change it. Till this day we have not needed to buy any… Read more ·  1

replacement foam layer, do any maintenance or spend any extra. It still in perfect condition and feels as good as the day we bought it. I've always been around 90 to 95 kg since we've owned it and I still love it. They say you get what you pay for well we have got plenty more than what we payed for as the mattress was very well priced for the incredible quality and build, the fact we've had ours this long and it's looking like we will get another 10 years we have saved so much money as a result. Best money we ever spent. We've also moved home twice and it's got convenient strong handles in good positions to easily move and carry it.

I don't recommend this mattress and don't understand what sleepingduck's commercial about having a steamroller roll over the bed even relates to. What's the point of showing a steam roller drive over the bed if it can't even support a 75Kg person.

The mattress itself is fine, but the way Sleeping Duck promotes replaceable foam components is misleading. The idea sounds great in theory, replace individual layers instead of buying a whole new mattress, but the replacement prices are so high that it’s almost the same cost as buying an alternative product.

Sleeping Duck have been helpful and keep checking on our progress. We will stick with the firm mattress as it seems to alleviate our back pain. Would recommend purchasing both base and mattress rather than fitting mattress on existing base. Unable to comment on durability as it is still very new. Hopefully will last a while! Mattress is a little heavy so changing sheets could be a problem but I believe there are devices to assist with this.
