Fast & reliable delivery. Easy to open and set up! Very comfortable, firm enough to support our backs but with softness for comfort too. Great when rolling over there is hardly any bounce on the otherside of the mattress! Very impressed with this as my first mattress in a box purchase! Highly recommend! Show details ·  1

Great mattress! As a long time side sleeper and back pain sufferer I can get pretty stressed about buying a new mattress. The sleep republic mattress is firm and supportive without being too hard, I can sleep on my side all night without my hips getting sore. Great service and quick delivery. Would highly recommend :) Show details ·  1

Mattress is great. Previous mattress was Snooze own brand madison time square. They still sell it but they don't advertise number of springs, thickness of foam layers, number of layers or show a cross-section. It was great for 11.5 years but woke up in pain every day for 4 months and eventually would feel pain immediately upon lying down. Bought… Read more ·  1

originally on super discount with family friend staff discount ie 66% off full retail.

Sleep Republic reviews are amazing, score on Product Review is amazing and score and review on Bed Buyer website is great.

Arrived quickly, been great since day one.

Springs feel very firm... but are medium firm officially... very firm in the sense they are supportive and feel like they cradle and push back. Smaller springs that are thicker means they should last longer and my weight is spread over more springs so each one will have an easier life.

Sleep Republic have gone all in on the spring quality with basic but tried and trusted foam layers.

Google the origins of the company- ​"Origin and History ​Founding and Experience: The company was founded by mattress industry veterans, including founder Mark Ottley, who has decades (stated as over 30 years in some sources, and over 20 in others) of experience in designing, manufacturing, and selling mattresses.

​Motivation: Ottley noticed the confusion and lack of honesty for consumers when buying mattresses, with many models being difficult to compare. He set out to create a simplified, high-quality product based on customer needs—medium-firm support, temperature regulation, and premium materials—and deliver it directly to the customer as a "mattress in a box." "​In summary, Sleep Republic's history is about moving away from confusing traditional mattress retail to offer a direct-to-consumer, scientifically-backed, and quality-focused hybrid mattress based on the decades of knowledge of its founders.

At time of review full retail price of my old madison time square king size from Snooze is $6799, Sleep Republic mattress paid $1400 with delivery included.

We bought 2 long singles (mattress and base) to join as a split king and only wish we had done it sooner. Apparently I am an Olympic body slammer when I roll over in my sleep and constantly wake my partner. No more! And no more sleeping on the couch when we both know we need a great nights sleep. This is a great solution. The mattress is… Read more ·  1

incredibly comfortable, we both felt the comfort factor on night one. Also having had a previous 'box' mattress, the fact that this one is hybrid with spring and memory foam, unlike our last one which was all foam, the breathability helps make this a much more temperature comfortable sleep. Every morning and night we register how grateful we are for this upgrade. It is firm but giving to softness on the top and our sleep is restful. Super happy with the whole experience from order to delivery to great sleeps!

This is an amazing mattress. Best decision I have made to invest in this mattress.. feels firm and soft at the same time. Not very firm and not very soft perfect balance of both. I have been searching for a good mattress over years. Being in my early 30’s I have a back pain issue and this mattress is perfect for me specially as side sleeper. I wake up on bed with no more soreness. Love it Show details ·  1

Absolutely love it!! I was so skeptical buying a mattress in a box, and dread the whole mattress shopping experience from past mistakes and horrible beds. I’m particularly precious… not too soft not too firm. I mentioned to my chiropractor I was mattress shopping and she asked if I had heard of Sleep Republic. She is not affiliated with them in… Read more ·  1

any way but said she has one and couldn’t recommend it enough and now a few of her clients also have them and love them. I am so in love with my mattress. It is an absolute cloud and so supportive. I’m so happy to be back in it after a work week away in hotel beds! I read reviews prior to purchasing that indicated they could be firm, but with the 150 day trial I figured it was worth the try! And I’m so glad I did!!! 10/10! Super quick delivery, easy to set up and it gives the dream sleep!

We did a lot of research after having a mattress we didn’t love for way too long. We got the Luxe mattress, and we have found it to be very comfortable, minimal partner disturbance, and so far, no big hill in the centre (as with our previous experience) Show details ·  1

 Follow-up  · To follow up, the unboxing was relatively easy, I would recommend two people for this part!. To be honest I am not sure about the mattress being cooler - I am a hot sleeper!. I have a cotton mattress protector also. The mattress arrived very promptly, we got updates so we knew exactly when it was coming.

The mattress is very heavy (over 50 kilos) which makes it very heavy to lift when making the bed. They also only deliver to the foyer lift if you live in an apartment or your bedroom is upstairs. Show details

My experience with this company: i found them to be very untruthful and staff are intentionally dishonest. If you try to return the mattress within the allowable time , be prepared to be ignored and lied to. They have been extremely rude, unassisting, dishonest, evading and unkind to me. They are super quick to take your money but they will do… Read more

everything in their power not to refund it. I have felt bullied and ignored every step of the way. I have never ever left a negative review however im absolutely appalled how horrible this company has been to me. Be very mindful before purchasing from this company. They do not adhere to their customers confidentiality . They emailed me a screenshot of customers phones numbers, email addresses and location. They certainly dont pride themselves on protecting customer information. After 3 weeks of trying to get my entitled refund with no success I asked to speak with the manager. The manager does not take or make calls. I have sent several emails which are unanswered. They ignore you. I have dropped the mattress myself to a charity store and told them I have no mattress and if they could process my refund immediately, they laughed and told me it will take up to 10 business days. They lack compassion and empathy . I also shared with them that i am chronically unwell and they have not made any provision to help me make this process less stressful . My advice buy elsewhere if you can because if for any reason you want to return your item they will make the process extremely difficult. The "customer service " team are extremely rude, dishonest, unhelpful, ignorant, unwilling and arrogant. The mattress itself, for me, was very uncomfortable. It felt like i was sleeping on a concrete floor .

A trip to Japan sleeping on ultra firm beds caused less exacerbation of my chronic back pain than my 'good' mattress at home, and was a real catalyst for change! I needed to sack the soft and switch to something firmer. I had some reservations about purchasing a mattress in a box, being someone who prefers a physical shop for purchases, but the… Read more ·  1

reviews were very positive and available videos and data informative, so I took the plunge. Ordering and delivery were very speedy, with great tracking. The unpacking process was simple. The look and feel was lovely. I really like this mattress! The top is cushiony enough and the firmness is perfect for me, with the right amount of give. I like that the sides don't sag down if sitting on the edge. My only tiny negative is that it does sleep warm, but the positives outweigh one negative! As a side sleeper with a trash back, the mattress has been a winner for me. I made this purchase a month ago(on sale so an even better deal!), and it's so far so good.

You may look at the price of these mattresses and think why would I spend that much but did you know you spend about a third of your life sleeping? Why compromise on a horrible mattress when you could get a sleep republic mattress. My dad recommended us these mattresses as he has had one for the past 7 years. His mattress still feels as good as… Read more ·  1

our brand new one. We have had ours for about a year now and not a night goes by where I wish we had a different mattress. With a perfect mix of firm but still cloud like. The previous mattress we had would dip in the sides where my partner and I would sleep and was causing us to wake up with stiff backs but with our sleep republic mattress we have never had this problem. Since we have bought our sleep republic mattress our sleep has improved immensely. For my partner and I this is the best investment into our sleep we have ever made. No i am not being paid for this review i am just a normal 22 year old Australian mum who cherishes an amazing night sleep, and truely believes that these mattresses provide just that.

This is my experience with this company. I bought a hybrid mattress (50Kg+) in 2020, two years later, I began to have issues with my back (I am under 70Kg in weight), the area of the mattress with the most weight (where the butt lies) was compressed. I started the warranty claim process, which was tedious. I had to demonstrate that I wasn't trying… Read more

to scam the company, and it led me to write a strong review about the customer service. I had to demonstrate that the mattress failed (photos, videos, weights over the different areas to see the weak ones, after many messages with the evidence, they finally agreed to send me a new one under warranty in 2022, I erase the bad review.. In 2024 I began again to have troubles with my back and this 2026 it made crisis. I wrote to the company again and, since I could not remember all this process (I am 81), I gave them the present address, which does not correspond with the first delivery or the replacement. Unfortunately, when you rent, most likely after a few years the landlord sells and you have to vacate. The fact of the matter is that after that last email I sent, I was completely ignored, so my only tool is this review to warn others. For me it is absolutely obvious that I received a non-advertised "seconds" the first time, hence the offer, and as usually happens, when you claim in warranty, most of the time you receive a "seconds".

I have been using the mattress for three months now. The mattress is quite high and sturdy, which is good. However it is not as firm as I thought it would be. Make sure to rotate the mattress every couple of weeks to keep the shape. The website said this is only for the first month, and afterwards we need to rotate it once a month. However, I… Read more

Purchased a mattress in 2023, after only 18 months it developed significant sagging in the center. After filing a warranty claim via their website, I was told that it is denied due to a minor stain. I was then asked to have it professionally sanitised and to provide a certificate of sanitisation, before any assessment would take place. A report… Read more

Sleep republic mattresses are so good that almost 8 years in and our king mattress is still going strong. No dips. Not too hot. So comfortable. No hip pain like other mattresses. I also have a back injury and it is so supportive. Just bought a new queen mattress for my son. Customer service to clear up an order error that I made was exceptional. Mattress came super fast and was easy to unbox. Such a great product. Recommend. Show details ·  1

Home delivery was very convenient. The mattress was easy to unpack and has proved very comfortable to sleep on. We are a large male and smaller female; we don’t experience any disturbance from movement at night. The mattress is very supportive and shows no sign of sagging after several months of use.

This mattress has been comfortable from day one. I have multipal issues with my back, hip and neck and this mattress feels so supportive but still nice a soft against the sore points. I haven't woken up as stiff and sore as I did with my old lattex mattress. I would highly recomend this mattress and the company for a great product, easy delivery and reasonable prices. Show details ·  1

We were a little dubious about purchasing a mattress in a box, having only ever purchased mattress in store.

feel as if you will roll out. Best feature for us is the lack of partner sleep disturbance - we no longer wake when the other gets out of bed. Happy with the level of support and the topper is not too soft (doesn’t make me feel too hot at night, like some memory foam toppers do). Highly recommend.

I didn't like going to bed. I didn't sleep well. I didn't wake well either. I've had back trouble for 25 years. At the urging of my wife I finally started looking at mattresses again. I reckon I read every Australian mattress review I could find, but only the one's where the writer wasn't somehow sponsored by a mattress making company. In the end… Read more ·  1

there could only be one, and I found it. It even came in a box. I'm not someone who would have ever considered buying a mattress in a box, not without first lying on it, and feeling it, and pushing the springs down, and bouncing up and down on it....before either changing my mind or giving up altogether. But because of the multiples of reviews by everyday people, I actually did buy a mattress in a box, sight unseen, A Sleep Republic mattress. And I haven't looked back since. I'm even back to going to bed early, mainly so that I can just lay there and read, before I doze off with my glasses still on. Goodnight. I love you.

From night one I felt so comfortable on my new mattress. It feels supportive and yet moulds to my body in such an easy way! Now I’m having 8+hrs sleep per night and I no longer have the hip and back pain keeping me awake. I’m soooo glad I bought this mattress.

Love this mattress, very supportive but comfortable. Can’t feel partner moving at all and I’m not too hot. Only gripe is it’s very slippery, and that’s with a pillow top, protector and then sheet. Still wouldn’t discount it though, maybe other mattresses using a similar outer fabric so would be the same. Show details ·  1

At the beginning I was ready to return my mattress for a refund. I realised I needed to give it more time. It did take awhile to get used to it, as every mattress is different. Some mornings I woke up with some soreness but now waking up feeling great. I have just had Hernia surgery and the mattress has made my recovery more bearable. Show details ·  1
