These mattresses are quite supportive. Though these mattresses aren't as supportive as a select few folks would like, most customers appreciate the supportiveness of these mattresses.
Edge support is very important for folks that face mobility issues or find themselves lying close to the side of the mattress. These mattresses do well on their edge support and they should supportive enough for most customers.
Bowling Ball & Density Tests
Many mattress reviewers use bowling balls to test firmness and support. These mattresses do well at providing even support throughout the mattress, which means they should work well to align the spine of your body.
Longevity is key to budget-conscious mattress shoppers. However, with mattress businesses competing firmly for profits, it is not always easy to find. That said, with customer feedback data and material specifications, these mattresses should provide above average longevity and last over 5 years for most. But, some heavier in body type sleepers may find them to be slightly less durable.
Sleepers report feeling very comfortable and satisfied with these mattresses, which means when we analyzed the current customer data, these mattresses had great percentages of high ratings. This is a good place to start to find out if one of these mattresses is a good pick for you -- read on for more specifics.

It's always difficult to find products that last over 10 years. Brands, by and large, hunt for short-term profits rather than building products that last. That said, there are still amazing companies to be found. These mattresses, for example, get high marks from customers on quality and durability. Most sleepers will experience them lasting between 7 - 12 years, though some who are of bigger builds may experience that they will degrade a bit faster.
Loving our two sets of bamboo sheets we ordered from Sleep Republic! We were so happy with the service and quality of our Sleep republic matteess that we thought we’d give the sheets a go! So happy we did! They are amazing. Super easy to wash/dry and the softest material I’ve ever slept on. Now that I’ve slept on these I can’t go back to normal sheets! The delivery process was once again one of the smoothest experiences I’ve had with online shopping!View More Reviews
Got My Queen Mattress a week ago with a set of Sheets! OMG the best sleets i have had in a while, had to buy more sets of sheets. Highly Recommend.
So comfortable and the delivery was quick!
.....they come in small boxes with wheels and disappear within 100 days if you're not compatible. We had a Tempur mattress for 13 years - it was great. Replaced it with another - very expensive mistake. After six months took a chance on a king size Sleep Republic mattress - Excellent decision! This mattress is everything it claims to be. The quality is outstanding. The comfort level is just right - not too hard/not too soft. Almost a work of art to look at it seemed wrong to cover it up but Sleep Republic's stunning bamboo sheets are the perfect complement to this mattress for the best night's sleep.
Awesome service have bought multiple mattresses now. Not just because of the product but the after market service. Recommended to family as well
Arrived within a couple of hours - and very very comfortable. Free bamboo sheets sheets have a fantastic texture.
Delivery next day after 3pm order . Mattress weighs about 50kg one person can handle it but two is a better option.happy with the comfort of the mattress worth buying as you cannot loose out.
Great mattres and great service i highly recomend sleep republic
The service and customer experience were excellent. The mattress was a little on the firm side for my partner and I but the return process was straightforward.
Queen Mattress is lovely! Can't complain
I am 188cm tall, weigh 113kgs and am fit. Five years ago I bought a very expensive plush top king size mattress - chose plush with my wife in mind - I prefer medium/firm. Over the past year I had been suffering increasing pain in my back and right hand side from hip to foot - so bad that most mornings I could not bend down to put my shoes on or pick things off the floor. Visits to my osteopath and physiotherapist weren't helping to any great degree - sometimes some temporary relief but that was it. In desperation I went onto the internet and spent days researching my options. Sleep Republic looked like the way to go - if it did not work I could return the mattress - nothing to lose. Have had the mattress about four weeks now. In the mean time I have been seeing my Osteopath on a weekly basis and doing daily stretch exercises - was doing the stretch exercises when I was sleeping on the plush mattress. Can now get out of bed pain free - no pain in the back or my right side. My wife was a little unhappy about having to give up the plush mattress but is sleeping very well on the Sleep Republic (SR). One difference between the plush mattress and the SR is the side of the SR is not as firm as the plush mattress to sit on - simple - I now sit on the bedroom chair to put my shoes on. As for the side of the SR when lying on the mattress - I tend to sleep right on the edge of the mattress and there is no give/falling away - all those springs keep everything even and supportive. Am still in the trial period so heres hoping all continues to be good. Gave the plush mattress to one of my daughters and she and her husband love it. The new expensive mattress they had was giving them grief - one person's meat is another person's poison - horses for courses. One final thing - I was worried I might be too heavy for the mattress. Contacted the company and was told the mattresses are 200kg+ weight tested.
Delivery supply second to none. Mattress is a bit to firm for our liking
The most comfortable mattress. Have bought two now for my boys. I’m next!!!!
Delivery to Sydney was prompt the next day (although the courier dropped one end of the mattress from his truck - about 1m - it didn't seem to do any damage). Unboxing was a fun experience despite the cutter tool being missing from the box, and the mattress is quite comfy so far. I'm used to firm mattresses but this one has been surprisingly supportive. Hopefully I can update my review in a few weeks once the mattress is properly broken in.
I am far from an ideal customer because having ordered a queen size mattress and having unrolled it, I then realised we actually wanted a king size mattress. I contacted Sleep Republic and they were wonderful, they said I could try the queen size for 100 nights and then for just the difference in price I could have a king size instead. The mattress is great, so many pocket springs make such a difference and the 100 nights trial is a brilliant idea. I would definitely recommend to anyone to try this mattress. My only other comment is that I will off-gas the new mattress in another room for a couple of weeks, my husband was fine with the mattress straight away but I got headaches at night for the first few weeks which I knew was due to the off-gassing and this would happen with any new mattress.
We live in outer metro/country SA and the mattress was delivered in 3 days which is really impressive. Packaging held up well considering the weight of the mattress. Unwrapping the mattress with the tool supplied was easy. Just make sure the mattress is in position before piercing the vacuum packaging coz it is heavy to move. The mattress is very comfortable and their is minimal partner disturbance. It took us a few days maybe a week or so to get used to the feeling that the mattress was hotter than we were used to, but don't notice it now. All up this is a great way to buy a mattress and the mattress does what it says on the box.
The quality of the mattress, pillows and sheets are next to none. The ordering and delivery process was flawless. Thank you.
I was sceptical of buying a mattress online, untested, but my husband convinced me it was worth trying. I'm glad. The purchase process was easy and our custom was clearly valued. We purchased about 4 months ago.The mattress has been fantastic. A little harder than I was used to but have come to love it. Also, I think my husband is snoring less now. All the best Sleep Republic, you deserve it.
The mattress is very comfortable and affordable! The reason 5 stars was not given was because there seemed to be an unexplained delay with delivery. It took a week, but the website promised same day delivery/ next day if ordered after a certain time.
Wow!! For the quality, service and price it was an absolute bargain! We'd only wished that we had purchased this earlier. We were initially a little nervous getting a mattress which came in a box but couldn't look past the positive reviews. Our main criteria was for a mattress with pocket springs for greater support, less partner disturbance and better air circulation so we didn't get too hot. We found that the Sleep Republic (SR) mattress had 2.4 times the number of springs (1,850 vs 768) for a QB as compared to a competitor (SD). Furthermore, the SR mattress also had thicker memory foam/top quilting (14 cm vs 10 cm) as well. We've now been sleeping on the SR mattress since Christmas and can honestly say that we've had the best sleep ever with no occasional body/back ache. We generally find that our sleeps are deeper and wake up feeling refreshed with less partner disturbance.
After a lot of research we ended up purchasing one of these mattresses. My husband suffers from a bad back and we struggle to find a mattress to accommodate it. From start to finish the company was impeccable to deal with, and I wish that there were more out there. The mattress was easy to set up - it is not that heavy, and I was able to manage it on my own (5'2 and weighing under 50ks, female). There was no lingering smell, something I'd been a bit concerned about. It was comfortable from the first night and best described as a medium in terms of 'feel'. As the weather warmed up, however, so did the mattress in terms of heat retention - and it is ONLY for this reason that I give it four stars. I tend to sleep 'hot', so struggled to come to terms with how much warmer it was to sleep on this mattress, than with a more traditional spring one. I contacted the company and they suggested trying a topper (no pressure - they simply offered the suggestion, or I could have easily returned it at this point). I tried one and although it reduced it to the point where I could have slept, I didn't like having the topper, so ended up returning it. The return couldn't have been easier - I emailed the company, the salvos in turn contacted me to arrange a suitable time to collect - and that very day I received an email from the company advising my card had been refunded in full. Very sorry to have returned it, but I urge anyone considering this mattress to give them a go. I'm not affiliated with them in any way, just completely impressed with the service and the mattress, had I been able to put up with the warmth aspect, was beautiful.
I had the mattress delivered to my door, and opened it in my room. After opening it easily, I let it decompress. There was a slight odour, but it was gone by the time I went to bed. Highly recommended, price for value is incredible!
After reviewing a wide range of mattress choices we settled on Sleep Republic and have not been disappointed. We are having wonderful restful nights sleeping. Must say we were sceptical about A Bed In A Box and wondered how it could possibly unfold into how they said it would but gave it a go anyway more so for the curiosity aspect and hey presto once unpacked we have ourselves a wonderful mattress. We ordered the mattress in the AM and it was delivered within a couple of hours brilliant fantastic service and with a 100 day money back guarantee how can you go wrong.
Delivered exactly as advised it would.
I have scoliosis and woke up every morning with back ache. I still wake up with a sore back but no where near as much. I am so happy I took a chance on this mattress. The whole process was quick,and easy . Watching the mattress expand was fun too.
I have now purchased two mattresses from Sleep Republic and both times their customer service has been exemplary. Even better - the beds are the amazing! Thanks so much - my husband wakes up each day with without pain in his (bad) back for the first time in 20 years.
The mattress is very comfortable and arrived promptly after order. It was easy to unpack from the box and set up.
So I waited for the 100 day trial to finish before I wrote this. I just wanted to make sure that there was no chance that the mattress was going to collapse, become uncomfortable or something along those lines. I would have to say this is the best decision I've ever made in the way of a mattress. I had been to the stores and tried so many and just could not make decision and thought that this was as good a risk as any. The fact that Sleep Republic did have the option to return the matress strongly influenced my buying decision. I do have a bad back. I certainly was concerned on how it would go, but this mattress has been so comfortable! I have an incredible night sleep, every night! I highly recommend buying a mattress from Sleep Republic. I tell all my friends about it all the time and they can't believe that I bought a bed in a box but it was worth the risk! Thank you Sleep Republic. Karen Ryan
I live in a country area of Victoria, I was pleasantly surprised when I ordered the mattress on Monday evening to find it waiting for me on Wednesday. You can't beat that for service! Mattress feels great to sleep on, no more waking up with numb arms. Very happy purchaser here!
Ordered a mattress and protector but only the mattress arrived. Contacted SR and the protector arrived express.
The mattress arrived very promptly and it unpacked itself brilliantly. I didn't notice any obvious smell - there might have been a bit, but it disappeared quite quickly. It is really comfortable. The only disappointment is that we probably needed to replace the mattress base at the same time, as there is still a little movement when my husband turns over etc. But it is not nearly as obvious as before and I am kind of used to it.
We needed a new mattress as both my partner and I were waking up with aches and pains from sleeping on our old mattress. I didn't want to fork out thousands of dollars for a new mattress from a major retailer so I searched online and found Sleep Republic (as well as some others but we chose Sleep Republic). They were quick to answer my questions and best of all, the deliver to the NT (for free!). I was reluctant to buy a mattress in a box but the 100 night free trial swayed me, as well as the returns policy. I put in an order for a king size and 5 days later it arrived (thanks TNT). My 14yr old daughter set it up by herself (poor thing cause it is a bit heavy). We have been sleeping on it for 2 weeks now and it's the best 2 weeks sleep ever. Felt fully supported, not too soft or too hard. No more aches and pains and no more partner disturbance. It is a bit warmer than our old mattress but no biggie. Well done Sleep Republic!
Very happy. Delivery was a breeze and unrolling the mattress far less daunting than expected. Loving the mattress so far. Had it cut a month now Would definitely do it again
Very comfy mattress. Lightening fast delivery!!
Excellent mattress that has releaved my back pain. Efficient company to deal with and I would highly recommend this mattress. Very happy!
I hate buying a bed - it’s confusing and expensive. With a 100 night sleep test, how could you go wrong with Sleeping Duck? This was one of my best decisions EVER. Love this bed :-)View More Reviews
Was a bit dubious about the support from a mattress in a box but couldn’t be happier
I was waking every morning with a sore back I’ve had issues with a long time. Although I still have some niggly hip pain I’m no longer waking in pain. We love this mattress, especially my partner. We went for a medium but thinking I could soften my side a little.
I am loving my new mattress. It has been easy to fall asleep without endless adjustments to find a comfy position.
Happy with our sleeping duck. Telling our friends about our cool new mattress.
Great mattress. Both of us are very happy with it.
Overall, very good.
Great customer service guys, a stand out from the rest, pretty much what we had expected and researched about Sleeping Duck. The side by side 2 king singles and bases are so far providing a very comfortable, spacious experience...Thank you Sleeping Duck team.
My daughter recommended Sleeping Duck . She had a Firm Duck - I tried it one night and thought it was a bit firm but liked it. I bought a Firm Duck and thought it was a bit too firm - I gave it a few months then Sleeping Duck contacted me and asked me how it was and I admitted I should have ordered Medium. They sent me Medium Firmness Layers and voila! bliss! Perfect. Best nights sleep every night! I can't wait to get into bed each night - thanks Sleeping Duck!!
I have Parkinson's and was having terrible trouble sleeping/resting on my old mattress since I got my Sleeping Duck I am sleeping 100% better and feeling rested after my sleeps. Thank you Sleeping Duck for helping my health & wellbeing!
Very happy with the purchase. The mattress is firm but comfortable. I used to move through the night and really interfere with my husband sleep. That stopped. If I move he no longer wakes up. Don’t even know if that happens. Wake up without any muscle pain. My Fitbit says I have a great sleep every night. Should have done this purchase many years ago. And I am not the only one. My husband feels really good since we have this mattress. It took us about 3 days to get use to this mattress. I would recommend to everybody. Five stars and not expensive for what it is. Well done sleeping Duck.
If I could I would never leave my bed, now that my mattress is so comfortable. My partner and I feel like we're sleeping on clouds and both get excited to jump into bed of an evening. I breathe a sigh of relief throughout my entire body each and every single night!
Our mattress was over 10 years old and my partner was complaining that he was uncomfortable.
Bed is great value. The bed base is a good height and quite stylish.
Wow! Just unravelling the mattress was an adventure and a thing of inspired wonder! My neighbour (who was helping me) and I couldn't believe that this HUGE mattress came out of that relatively small box.
I bought the single mattress for my 9yr old son, however while the mattress is undeniably comfortable, he does become quite hot.
You guys are amazing. SO impressed with the packaging. We videoed the mattress growing..... SO comfortable and no more bad back !!!! Thank you
We have a split mattress (firm and medium). It suits us down to the ground. It did take a little while to get used to how firm the mattress is - especially compared to our previous mattress. My number one reason for getting a new mattress was to get better support for my back. Sleeping duck provides this. I have no hesitation recommending them. Impressive customer service, great product - compelling price. What more could you ask for?
My partner has trouble finding a mattress that he's comfortable with - we've bought many mattresses in the past 15 years and we have only found one that we were able to keep and really needed to replace it - the Sleeping Duck was the 6th mattress purchase we made and fortunately it was comfortable for both of us. Being able to get a refund if not suitable was the reason we tried it, having been unsuccessful so many times in the past and at great expense.
What an improvement on our old mattress!! Our new mattress is very comfortable and I am no longer awoken by by husband's tossing/turning. The firm mattress was a bit too hard so Sleeping Duck cheerfully delivered medium layers which were easy to instal. I recommend this product.
Previously we had switched from an old mattress to a firm memory foam and after six months I had bad shoulder pain being a side sleeper. I read up about Sleeping Duck and hoped the reviews are true. It arrived and we weren't disappointed! My husband and I now have a great nights sleep. My shoulder pain has gone and my husband who is a tummy sleeper loves it to. I'm saving loads on chiro and physio and the medium firmness is perfect for us. Relieved we made the right decision and for a price that was similar to our previous foam mattress but the Sleeping Duck is a hundred times better!
I was recommended to buy a Sleeping Duck mattress from my friends who even had a sleeping duck mattress shipped to them overseas! No regrets wiht my mattress, the quality of my sleep is amazing, I can't believe it too me so long to get one!
We were previously sleeping on an expensive "brand name " mattress which cost us three times the cost of this sleeping duck . It was causing us to both wake in the morning stiff and sore. We did a huge amount of online research before deciding to trail the sleeping duck mattress .We did decide on the medium firmness mattress at first but decided to exchange for the firm foam inlay after some weeks . The swap over was completely painless and we are thrilled with the result. We couldn't recommend this product highly enough and the level of customer service received .Thank you for a great product
I have Sleeping Duck mattress just over 2 months. It is just a sleeping beauty! I often had so many sleepless night and lower back pain before but now I experience with my Sleeping Duck mattress I sleep well and the pain has gradually disappeared and I feel good to wake up every morning. Thank you to Sleeping Duck!
Extremely happy with the product and service , began with the firm and swapped to the soft due to shoulder soreness (pre-existing ) . Swapping was very prompt .Definitely our best mattress purchase and we have certainly had a few
Great mattress, we both love it
Fantastic purchase and no regrets. A great night’s sleep is now the new normal for us. 😁
I sleep very well. It went for the harder version, but added a topper.
The customer service was great- I changed the level of firmness and it was a good call. It's a great mattress. Only good things to say.
Mattress hunting was so confusing it seemed we better spend every penny saved plus max out the credit cards if good sleep was going to be even remotely an option. Once we discovered Sleeping Duck online everything changed. What we read made sense and all at a ridiculously reasonable price. It was worth the plunge even if it was all sales tactics. True to their word, just like a new pillow it took about a months to settle in. Each night seemed to get better until I forgot about the new mattress and could just get on with sleeping. I can say straight out that I will buy a new mattress much more regularly and won’t bother looking anywhere else. Beyond happy is an understatement.
As I read in other reviews, I was dubious about buying before trying and I’m well known by my friends and partner every time we go to a hotel or motel, which is about 20 times a year, for complaining to management that I need a mattress topper or some sort of complaint about my bed. None at all about sleeping duck. So beautiful to climb into at night! Don’t feel my partner moving, he can’t feel me moving and I’m like a washing machine in bed, always turning. On top of this the price was amazingly cheap for such great quality.
Initially went for the firm which we have had on other mattresses previously. But this was rock hard. After an email these guys made a few suggestions which made it slightly better.
The entire process with Sleeping Duck has been amazing. Their customer service is absolutely fantastic. The ordering process was easy. And the mattress is awesome, we are so comfortable now and have the best nights sleep. Extremely good value for money an added bonus!
My husband had a back injury requiring surgery and I was waking up with back pain each morning. We bought a firm Sleeping Duck which was brilliant for my back sleeping injured husband but for me as a side sleeper, my hips ached. I waited the 21 days and requested my side be changed to medium. My new foam arrived in 2 days to country NSW and we just unzipped the mattress, removed the firm layer and put my new medium layer in my side. They are 3 layers deep so no affect to the top of the mattress. So incredible! We also got to keep the firm layer just in case which is amazing quality. This $1,399 mattress replaced our 12mth old $3,500 mattress and we tell everyone about it! Thanks guys. You should be really proud of your product
Before purchasing one of these mattresses i did my due diligence and researched the company and read a lot of comments on product review its my go to site for any purchase, its generally pretty accurate and on this occasion spot on, not only do this company make a great product their customer service is second to none i'm 63 years old and dealt with a lot of companies in my lifetime making purchases and its so refreshing to deal with someone who cares about their customers, its the great work they do behind the purchase that ensures you have the best sleep possible,iv'e had this mattress for 3 months now and love it, i have no hesitation in recommending their product to you,but as always do your own research first.Cheers Ian
Firstly, the opportunity to test a mattress for 100 nights.... it doesn't get much better than that.
The Customer service with this company is unheard of. I wish all companies were like this. These guys don’t rest until your happy. The product is awesome. Everyone needs the duck!!
I did a lot of research before we bought our Sleeping Duck mattress and there were a lot of positive reviews. Based on that my husband and I went ahead and purchased both a king mattress as well as the bed base. It arrived well packaged but we needed to get the bed base assembled for us as it was a bit complicated to do it ourselves. Since the first time we lay on it our whole sleep experience changed for the better. What a mattress! Comfort beyond comfort. I could not recommend it highly enough.
The mattress is supremely comfortable and very enjoyable. Thoroughly delighted with it.
