Excellent delivery time. I loved the option of the old mattress pickup, even though we didn’t need to use it. And now to the mattress - great to sleep on. We love it. Bye bye feeling the mattress move every time my husband turns over. Thankyou too for the stuffed koala toy - a present for my dog hehe.
Wow, we love our new mattress, feel like your sleeping on a cloud. Thank-you. Nola
Very comfortable!!! So worth the money! Delivery was great also
Love our new mattress it’s super comfy, firm and supportive. So happy we bought it!
You will absolutely not regret it! Delivered on the 3rd day which was super fast for a regional area. No fuss, no issues! Best nights sleep! Well done Koala!
Very happy with our new mattress!! My wife doesn't complain of waking up with back pain anymore!
I have now slept on the Koala for 3 nights and have found it very comfortable and supportive. For the price, I Think it is a very good buy.
Best sleep ever
Koala king mattress
Comfortable and quick delivery
So far so good.
I ordered my mattress in the morning and it was delivered at 2pm the same day. It’s sooooo comfy and you never feel another persons movement at all. I love it
Very impressed, good value for money and a really good product
New mattress after waaaaay too long. The Koala is just what these aching bones needed
Great mattress, prompt delivery,,,,always a little sceptical ordering without testing but this mattress is a beauty.
We originally purchased the queen size mattress. We slept on in for almost 2 weeks, noticing it was 5cms shorter then our previous queen we swapped for a king. Very happy with the king and the swap was made very easy. We originally payed with afterpay, but we were able to repurchase the new mattress the same day the took the queen away and king was delivered 5 hours after ordering. Mattress took some getting used to, as any new mattress would. But all in all very happy with my purchase and the koala team were pretty helpful. Thank you
so far so good after 3 nights
Very comfy! Very great! Recommend.
Love the mattress - best we’ve had!
Literally everything about this mattress was awesome. Same day delivery with tracking, the affordable price tag and the mattress itself is comfortable.. And the best part? I can't feel it when my partners gets out of bed in the morning. What more could you want!
We bought the mattress not long ago and we love it! It's so comfy and it was so handy that it could be delivered so quick. We just bought the couch which is coming tomorrow and we can't wait to try it out. Please make a matching chaise/ottoman and maybe even some pillows!
Mattress is taking time to adjust to but we are getting there, it has just shown us how old our other mattress was. Sleeping better overall, my back pain has reduced & really loving the ‘non partner disturbance’. Only thing I feel it is missing is the ‘anti roll out’ edge on the mattress so the edge collapses when you sit on the side of your bed. Other then that the service has been great.
Very comfortable to sleep on and light and easy to manage.
Mostly lives up to the hype. Is a nice firm piece of foam and generally performs as described, as in, limited disturbance to sleeping partner. Appears close to the suggested hard/soft balance if not a little on the hard side, might body form after a bit longer timeframe. Also appears to not quite ‘breath’ as well as suggested, as in, not quite as ‘cool’ to sleep on as expected. However, this said, it is still quite a comfortable mattress and leaves no ‘sleep pain in the morning.
Quick delivery & great service. In terms of mattress, my husband thinks it’s great. I’m still getting used to it. We also get our kids to try it as we consider to get one for them as well.
The Koala mattress is very comfortable ,and i will be keeping it forever , thankyou Koala Mattresses
I am ex infantry soldier, incomplete paraplegic and double amputee Australian Para Athlete and 50yrs old. I have had many mattress to try and sleep on. This koala mattress is the best I have ever slept on. As an athlete I train hard but as a double amputee I couldn’t sleep on my side because of no legs (=no balance). With the koala mattress I can sleep on my side again and get the best night sleep I have had in many years. I WILL NOT BE RETURNING THIS MATTRESS. Mark Urquhart
I wasn’t skeptical, I just couldn’t see how an inexpensive mattress could actually be a game changer. But wow, I get it now. And I’m a normal, real person now giving another 5 star review. I live in Newcastle and I received my new King Sized Koala Mattress the day after I ordered it. I kept in mind it takes up to 30 days to get used to a new, supportive mattress. It’s been a week - my mind is blown, I’ve never woken up as refreshed! After 2.5 years of dating, my boyfriend and I rarely shared a bed. We’re both over 6ft and restless sleepers. We would sink into the middle of my old, too soft, queen mattress. We can both sleep soundly and comfortably on the Koala - no partner disturbance! He’s been over nearly every night for the past week! Koala.... I think you guys will be responsible for my boyfriend and I moving in together (thanks for that ;) )
My husband and I desperately needed a new mattress, so we figured we’d try the Koala because it was a great price, and had a trial period with a money back guarantee. I have back/hip problems and whenever I sleep on a mattress other than my own, I wake up in a lot of pain. The koala mattress arrived much faster than we thought (we live in a rural area) and was very easy to unpack. We love the removable cover and we found it very comfortable to sleep on. The first night I slept on it was the deepest sleep I’d had in a long time and I woke up with no pain! If you’re thinking about trialing the koala, just do it!
Great mattress, very comfortable sleep. Delivered the next day. Will definitely buy another.
Read reviews and with 120 days offer we thought what have we got to lose! Ordered Wednesday arvo on our doorstep Friday afternoon and slept on that night! Love it, we were sceptical but have had great nights sleep since and I don’t even know when my partner gets up, numerous, during the night. If you’re thinking of buying a new mattress go for it.
Ordered and delivered next day. Very comfortable
Good mattress and very convenient to deliver in less than 24 hours. Informed every step of the way about the status of the order
Bloody comfy, best matress ive ever had
The process of ordering was great, and the mattress is fantastic. The only downside was the delivery company. I ordered it to be delivered in a 5-8 time slot and it came at 3:00pm. Luckily I got home from work early.
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!
