This mattress strikes the perfect balance between comfort and support. The memory foam contours to the body, easing pressure points, while the firm base keeps the spine aligned. It sleeps cool, minimizes motion transfer, and feels durable. Great value for restful nights. Show reply

Excellent mattress, this is actually our 3rd sleeping duck mattress purchased for our household, my partner and I have a king size sleeping duck mattress, our daughter has a double size sleeping duck mattress and the current one I am reviewing on is our son's, also a double sleeping duck mattress.

Looks and feels solid . Big plus for its removable and washable cover I cannot recommend it enough to everybody . I simply love it Show details ·  1

My Sleeping Duck mattress has changed my life! As someone with head-to-toe joint pain thanks to a genetic condition, I looked high and low for a supportive mattress that didn't feel like laying on a rock (or cost me a small fortune). The firm SD mattress has almost completely eliminated the joint pain that I used to get after sleeping/laying down.… Read more ·  1

It feels plush to lay on, but you also get that solid feeling of support underneath which is a difficult combo to find in a mattress. The topmost layers are foam (which did concern me as I'm a hot sleeper) but unlike other foam-topped mattresses, it feels breathable but supportive. I love that you can remove all the foam layers to vacuum them, and their covers are machine washable - great for folks with allergies or if you have a spill. You can also replace these foam inserts and their covers down the track.

I would genuinely recommend Sleeping Duck mattresses to absolutely anyone, young or old. The ordering process was simple, delivery was free and fast (even in a regional area), and the 100 night money-back guarantee gives you peace of mind. For the price, SD mattresses are unbeatable. The customer care alone certainly beats traditional brick-and-mortar mattress stores.

Just so so – Today after a couple of years of fair sleep on my SD mattress it's now resting up against a wall as I try out another mattress in a box. My one abiding thought is that all these box mattresses are too firm. I tried medium at first, went with firm and because I was never advised that there was a soft option, I had to pay $150 for the soft foam… Read more

layer.

I have never slept well with this mattress and I fear that the one I have now with a girl's name will be the same; too firm.

So my advice is that if you are in any way dissatisfied with your mattress that has 100/120 night trial period, send it back. I now have a $1250 mattress that will be going to the op shop.

SD customer service was also fairly spotty with no one contacting me about how the bed was going and as I mentioned, I was never told about the soft option.

I find it amazing that people say they suddenly had the best sleep on these mattresses. There must be an awful lot of shocking sleeping arrangements out there. I only use this mattress when I stay up later than my partner (which is often) and I don't want to wake her. We have a latex mattress that kills this and in the main guest room we have a plush mattress that guests say they love.

I think I have done this other room's mattress on the cheap and if it does not work out, I will be back to the main retailers.

Love love love my Sleeping Duck! – I have arthritis and I was getting desperate to get a solid sleep without waking in.pain every few hours. I decided to try Sleeping Duck after seeing some on line advertisements. OMG so amazingly comfy, however because of my arthritis and weight it was too hard for me to move in my bed so I was back to restless sleeps, even though my bed was the… Read more

most comfy bed I'd ever experienced. Sleeping Duck contacted me to see how I was enjoying my new bed, I reported that although the mattress was incredibly comfy I was no better off sleep satisfaction wise. Sleepung Duck immediately came to my rescue by suggesting I try their firm insert, and within a week it was at my door, no 3xtra charge AND I got to keep the original insert in case I ever wanted to use it. The new insert was very firm, I could sleep longer maybe 4 hours? But I was still waking in pain, I decided to put the softer foam ontop of the mattress under my underlay, and now I feel like I've got the perfect mattress for me, I can move easily, I can sleep for longer, and although I still wake with aches and pain, its no where near the scale that it was. Thankyou Sleeping Duck for having such amazing customer service and such a deliciously comfy copy bed.

Painful shoulders after 3 years – Firm option. Good for back but over the last three years my shoulders are now painful every morning. Am a side and back sleeper. I asked SD more than a year ago whether I could get a soft layer so I can customise the shoulder areas to soft but to no avail. Just tried again to see what they say.

Be patient - so worth it – This mattress took a minute to get used to. Instant comfort wasn’t how I experienced it - it took a couple weeks to adjust with a little discomfort and a few achy nights from that adaption (bit of stretching next day was fine to deal and after a week or two no issues at all.) I am so so so happy and cosy with it now. Had it 5 months, so far so… Read more ·  1

good. Heavy so take your time adjusting and spinning it. Most standard double fitted sheets will fit on it but tight - this doesn’t phase me as I love my bed so much. The firm is amazing. I thought I’d need the extra firm but that setting felt like concrete after a week on the firm. Highly recommend this mattress for value, comfort, and it is so snug now it’s winter. Sleeps warm in the summer so adjust bed linen and ventilation in your room if need be. Can’t have everything but this mattress is super close to it!!

Absolutely Love Our Duck – Our firm double bed size has been an immediate success. We both commented after just the first night how well we slept. Our previous mattress had sagged and aggravated some long term back issues. We could not ask for anything better than continuing good sleep. Show details ·  1

Not Firm in any way – Sleeping Duck sounds very promising, new product, extremely well marketed. Very narrow product range with only soft, medium and firm available in all sizes. Stores don't exist for you to try and feel. I wanted a Firm mattress and clearly asked if they have an option. I went for the firmest one available and it was nowhere close to Firm as it… Read more

mentions.

Very comfortable otherwise with its top coverings but lack of back support I felt as you just sink in the matress. I think most people like it especially the comfirt but I would be sceptical for its long term back support.

Product: 3 stars just for their Firm option. Product NOT as described. Build quality: is ok, nothing super special or aeronatucal scince as they advertise. No side/edge support as they advertise. Single spring mesh, no pocker springs. Firmest option available is very soft, not suitable to firm sleepers. PLUS, it retains heat, ok for winters, not good for summers. Customer Service: 6 out of 5 stars, the best I have seen. I had to return the mattress and they returned it without any issues whatsoever. Price: Expensive for this quality and build compared to others.

My new friend in the bedroom – I first slept on the Sleeping Duck only 5 hours after unpacking it. By that stage it had expanded to a thickness of about 18 cm. But it continued to grow and now it's about 30 cm thick! Extremely comfortable, firm but in a pleasant way. The only downside is that I will need to buy some larger sheets- my old ones don't tuck in any more! The Sleeping Duck is the most rewarding purchase I've made in the last year. Show details ·  1

It is lovely. So good, the dogs have commandeered this bed – It is very comfortable and supportive. It does not bounce, it is firm yet cushioning, and assists with sore backs. Sleep is deeper and less disturbed. No sagging is detectable although we are still in the early days. Show details ·  1

Total package – After three premium branded beds, all sent back, I despaired of finding a bed to suit me. Then I heard of Sleeping Duck. From its well conceived delivery and installation this mattress and base fulfills all my requirements. Wonderful support for my back, maintains its support with no ridges or sagging, and my sleep has improved immeasurably. Compared to other overpriced beds Sleeping Duck is outstanding. I highly recommend it. Show details ·  1

Almost perfect, just not sure why the mattress is so short – Really happy with the mattress and how much better my sleep is now. As said in the title, not sure why the mattress is so much shorter than standard doubles. Maybe the length is different to a standard queen-size (which I had previously), but it's a good 20cm shorter. Show details
