As an 89 year old I was concerned about purchasing a mattress, sight unseen over the Internet. However, I found the whole process easy and the delivery and follow up first class. The mattress exceeded expectations. I had a couple of queries which were resolved by “Amy”and the team within the hour. The Sleeping Duck team turned a purchase into a satisfying first class experience and would be my first choice for any other purchases. Show details ·  1

Sleepingduck Mach 2 Q mattress plus sleepingduck indestructible base. After 3 spinal fusions and major muscle atrophy sleeping has become a literal nightmare for years and I've tried over a dozen mattresses and various bases. This setup is by far more comfortable and supportive, and easily as high quality as any of the more expensive mattresses… Read more ·  1

by sealy and king koil and tempur etc i tried, Above and beyond customer support that always keep their word and helped solve problems very quickly to help make sure i was comfortable and happy with my product. It's 20x the quality of Emma mattresses. I wake up with significantly less backpain and difficulty moving after a longer sleep each morning now than i did before, i love being able to change the firmness or go half and half.

AAAMAZING purchase experience. The delivery driver was extraordinary and brought my mattress up a large flight of stairs - solo! The instructions were perfect and OMG…the COMFORT! I don’t know why I didn’t order this aaaages ago! My queen mattress feels like a king because we can sleep right up to the very edge, with no roll or instability,… Read more ·  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. The option of guaranteed next-day delivery - or being able to properly plan your delivery - is outstanding and removes any stress from the process. We recently… Read more ·  1

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.

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.

It's like sleeping on a nest of comfort, I love the new mattress. I'm incredibly happy with the decision to buy a sleeping duck. Only downside being that it took a few days for the new smell to dissipate - didn't stop me sleeping though, I seem to fall asleep more quickly too. Show details ·  2

 Follow-up  · Still loving the new mattress, in answer to a few questions, please see the following: Edge support is great, no sagging, the mattress does not sleep hot, which is great for me. No partner disturbance, the mattress doesn't dip, the internal supports acts independently.

We were looking for a mattress and a bed frame and I'm sure the indestructible frame would have been excellent- however we decided on a frame from another manufacturer in a style we really wanted and knew was very strong. We were pleased with the… Read more ·  1

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.

Good base but can be improved Comfort level is such a subjective measurement so I will speak of my experience. I went whole hog on Sleeping Duck buying their indestructible bed frame, mattress, sheets and duvet. Service 5/5 Delivery of all products including additional component adapt foam to try a different firmness level was on time and per… Read more

expectation. All questions I had were answered promptly. I can’t comment on return of mattress as I choose to keep it after much deliberation.

Indestructible bed 5/5 So as the name suggests it is built like a tank and the materials used are of high quality. Essentially you need to build it on the spot you want it to remain as it would be heavy to move even with the help of two people. The build itself is not too difficult but there are lots of bolts screws etc. Fortunately everything lined up so no great dramas here. I did however looked on the internet for a YouTube video which shows the build process. That was incredibly helpful and gave me the confidence to proceed with the order.

Mattress 3/5 This is the interesting bit and subjective. I come from having your standard inner spring Sealy mattress. So I am used to a more responsive mattress. Foam does have a different feel about it. The other thing I had noticed during my testing period, which was predominantly the summer months, I found that it retained a bit of heat. This is why I deliberated for such a long time on whether or not to keep this mattress. I was determined to see if this could be resolved as I like all the other aspects of the mattress including a removable washable cover and swapping around the foam for longevity. I went about changing the component adapt foam and purchasing the SD sheets and duvet. These things did not help much or if any. I was coming to the end of my trial period and thought there is a lot to like about this mattress and spring base but what more can I do. This isn’t rocket science. I have been reading a lot about latex. Perhaps this can both address responsiveness and heat retention. I took a chance and bought a Quokka basic latex topper and replaced the antigravity foam with it. At this point the trial period was about to end so it was a risk. Certainly the topper had the responsiveness I was happy with but I don’t think it truly addressed the heat retention. Heat retention is a double edged sword. In summer it is not great but in winter it is a blessing.

Sheets and Duvet 4/5 The sheets and duvet are incredibly soft and light weight. Although for me they don’t address heat retention of the mattress they are a good addition.

Good luck on your trial period and hope this commentary helps.

[4 in 10 years]. I even suggested Sleeping Duck to… Read more ·  3

others in the hope that they would be my guinea pigs. I'm now writing this review because the reviews from my friends were an overwhelming thumbs up. I love this mattress because it allows me to wake without stiffness and pain. I love this mattress because I sleep for a full night instead of 4 to 5 hours. I love this mattress because prior to this, I had a mattress and a topper which made the bed too high and too heavy when changing the bedding. I love This mattress because I have a full array of fitted sheets that I can now buy because the height is 30cm instead of 50cm. [ needing a topper for comfort raised the bed by 20cm and its difficult to find fitted sheets with a 50cm height]

There's only one thing I don't love about this mattress ... My partner says that it's too comfortable.. goes to bed too early and sleeps in way to late into the morning.

My back, hips shoulders and neck don't scream at me anymore!

I LOVE MY SLEEPING DUCK MATTRESS !!

My new Sleeping Duck mattress is absolute perfection. From the moment I lie down to the moment I wake up, it’s superb. I’m sleeping better than ever, and a lingering niggle in my lower back has completely disappeared.

We did a fair bit of research pre buying. We were impressed with SD promo material. It stood out from other bed promos which often had a discount - but price was only one consideration.

it could be too hard, but no issues after a week. We now both love the firm mattress. We were initally concerned about assemblying ourselves, but no issue at all as long as there are 2 of u. The bed frame is incredibly solid and strong. We are awaiting the auto sheet refresh module, which was not available at the time of ordering. Given the weight of the mattress, we consider this is essential to make it easy to change sheets. We highly recommend the bed & mattress at what we consider to be a reasonable price.

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.

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.
