 AI reviews summary 

The Koala Plus Mattress is highly regarded for its exceptional comfort and versatility, with many users reporting significant relief from chronic back, hip, and shoulder pain. The customisable nature of the mattress is a standout feature, allowing sleepers to toggle between firmness levels and seasonal temperature sides. While the initial setup is generally straightforward, recurring feedback highlights a strong chemical odour upon unboxing and a base feel that is firmer than some expected.

Pros
  • Customisable Comfort: The flippable topper allows users to choose between medium-firm and firm settings, while the seasonal layers provide effective cooling for summer and warmth for winter.
  • Pain Relief and Support: Numerous reviewers report a marked reduction in back and joint pain, noting that the mattress provides a "cloud-like" feel without sacrificing essential spinal support.
  • Minimal Partner Disturbance: The mattress excels at isolating motion, ensuring that movement from partners or children does not disrupt the other sleeper.
  • Efficient Delivery and Service: The purchasing process is frequently praised for fast delivery (often next-day) and responsive customer service, including the provision of free toppers for those who find the base mattress too firm.
Cons
  • Strong Initial Odour: A significant number of users noted a strong chemical "off-gassing" smell upon unboxing that can take anywhere from a few days to two weeks to fully dissipate.
  • Firmness Levels: Despite the adjustable layers, some sleepers still find the mattress excessively firm, occasionally requiring an additional mattress topper to achieve desired plushness.
  • Weight and Handling: The mattress is noted to be heavy and lacks side handles, making it difficult to manoeuvre, rotate, or lift onto bed frames.
  • Heat Retention: While many praise the cooling side, a segment of users found the mattress can still sleep hot or that the "cooling" technology was less effective than advertised.
Verdict

The Koala Plus Mattress is an excellent choice for those seeking a supportive, customisable sleep surface with proven benefits for back pain and motion isolation. While the initial chemical scent and high firmness level may require a brief adjustment period, the brand's trial period and proactive customer support mitigate these risks.

We bought the Koala plus mattress a month ago. If has been amazing. So comfortable and we have such a restful nights sleep. They have a 90 day return policy but there is no way this mattress is being returned. Love the mattress. Medium firmness. So good Show details

We purchased the Koala Plus Queen mattress in March. Both my partner and myself have chronic back pain, and were hoping the new mattress would considerably alleviate our pain and discomfort. It’s early days yet, but there’s been no improvement thus far. Perhaps our expectations were too high. We’ve tried both the semi-firm and firm options.… Read more

Semi-firm seems to suit us better. Next step is to try a topper. We realise that improved sleep may take time, so are not giving up. The mattress is very comfortable when lying down to sleep.

Many things can wake me at night, but these days a dodgy mattress is not one of 'em. No longer do I anticipate discomfort even as I finally fall into bed at night when my body so needs to rest and repair. The integrity of this Koala mattress can be seen as well as felt – it just looks better when made up. :) Show details

Love love love our new koala mattress! It’s just what we needed, firm but soft and cool for summer. Can’t wait to flip the top when winter comes . Oh and the no partner disturbance feature is my fav. I hardly notice if my partner moves or if my toddler climbs on the bed with us Show details

Second mattress we have purchased from Koala and this one was for our 5yr old. Easy to unbox, takes no time at all to air out and from ordering to sleeping on the process only took 3 days. Our child had been tossing and turning constantly during the night and kept complaining about her mattress, which was a good mattress that cost $1800 only 4… Read more

years ago from another brand. Willing to try a new mattress as we have the king size mattress ourselves I ordered the king single for our daughter and so glad we did. She has slept without minimal disruptions and even wakes with a smile on her face just from how comfy she said she feels. Will keep purchasing products from Koala as all experiences have been A+

Online ordering was super easy and it came within a few days. Took up the option for delivery and set up as the packaging is removed. So far so good as was seamless. Then the test once set to medium firm. First impression a little firm. Then what happened next is amazing. Great sleep from the get go. Somehow it is so comfy and supportive and the… Read more

aches and pains from the old mattress completely disappeared. It's like you are floating on a cloud. Partner disturbance is fantastic. Seems a great quality mattress and we are now converted to foam and never going back to an old style mattress. Thank you so much Koala!

Want a good nights sleep? – As another family member highly recommended a koala mattress i searched some reviews on the top bed in a box mattresses and decided to give koala a… Read more

go. We live rural and when our first mattress arrived it had malfunctioned and expanded in the box. When it came out it was all out of shape. So we got in touch with koala warranty and submitted photos. It did take a little while to process as it was there Boxing Day sales and they were swamped with orders. They happily processed our claim and sent us another mattress. From the first night it was slept on our son loved it. I told him he had a period of time to test it and if he didn’t like it he could send it back. He said no way I love it, and to this day he still does. He has had neck surgery and says his back doesn’t ache anymore. Next time I get a new mattress for our bed it will be a koala one. Our family member upgraded their mattress from entry level koala king single to a queen size koala plush, and he says it’s even better. Even though he said his previous mattress was still as good as the day he bought it, and it was more than 5 years old. I even recommended koala to an apartment we stayed in on holiday as there mattresses were stuffed. So if you are not sure take the plunge and try them I doubt you will regret it.

 Follow-up  · We live remote not metro and the delivery was less than a week, however we purchased during the Black Friday sale and therefore had a waiting period due to high demand before we were informed our delivery was on the way.

I love that Koala is extremely prompt with their orders. I ordered a mattress one day and it was delivered the next! This is our second Koala mattress and we love how supportive they are, and the interchangeable topper that gives you a choice of… Read more

firmness - so comfortable! I suffer chronic back pain and really need a mattress that supports well. The cool topper is perfect for us too as we're both "hot" sleepers. It's so great that you can trial the mattress and still get you money back if it doesn't suit - not that we would send it back - it's too comfy!

 Follow-up  · The mattress, whilst heavy, was easy to unbox, if a trifle awkward to get onto the bed frame. When unboxing, try to lift the box onto the bedframe, undo each end of the box, and let it slide out onto the frame. This is way easier if there are 2 of you to manoeuvre it! Once you get the plastic off, the mattress sorts itself out. We love the cool… Read more

that, so we bought the mattress and it is fantastic, I felt taller the first morning. My neck and shoulder issues have gone. So comfortable and the perfect temperature for sleeping. I no longer feel my partner turning over. We are really impressed and wished we did it sooner.

Thank you Koala

Koala Queen Mattress – I recently purchased my Queen Mattress, and I am beyond thrilled with my experience! The mattress is a perfect blend of comfort and support, offering an awesome plush yet firm surface that provides excellent back support without feeling too hard. I've had some issues with back pain in the past, but since sleeping on the Kola mattress, I wake up… Read more

feeling refreshed and pain-free.

The quality is exceptional— for the mattress itself it is breathable and stays cool throughout the night, which has been a game-changer for me as a hot sleeper. I also appreciate the edge support, making the entire surface feel stable and usable, no matter where you lie.

In addition the setup is soo easy. The mattress expanded quickly and had no strong odors like other mattresses I've tried. It's been an absolute dream to sleep on, and I look forward to getting into bed every night. I couldnt go past this mattress for looking for a comfortable, durable, and high-quality mattress it’s highly recommend to give it a go!

Great Sleep on Koala King Mattress+ – I ordered it in January, 2024, received it in mid February of this year (2024). [It was a KOALA KING BED AND MATTRESS PLUS DREAM PACKAGE). The delivery boys were amazing (though of course, another company) and so attentive. Their office staff member has been on call all day.... We had a few guests sleeping on this mattress till mid June. Hence, … Read more

now, on Jul the 18th, our own personal experience is only about 5 weeks old. Having said that, so far, we (I and my husband) have only praises for this mattress, both from our guests and our own. We sleep very well, though cannot speak of any special effects. Given the short period of usage, the mattress durability has not undergone any serious test yet and therefore we are unable to comment about it. NOTABLY, WHILE OUR FRIEND (Max Greenhalgh) SERVED AS A CONTACT PERSON, THE BED AND MATTRESS WERE ORDERED AND PAID BY ME (nava moran) AND DELIVERED TO our PLACE, (u1001, 221 Sydney Park Road, Erskineville, NSW, 2043). Hence, any further correspondence should be kindly sent to me at nava.moran@mail.huji.ac.il , thanks

Fantastic Sleep would highly recommend – I have severe spinal stenosis and needed a good mattress, I choose the Koala Plus and have been very happy. The changing of the topper to soft or firm was good as i needed firm and it is great for my back. Sleeping has never been so good, i would highly recommend the mattress especially for those with back problems. The setup was very easy and… Read more

instructions provided where spot on. The delivery process was also quite quick as I live semi regional I was expecting a longer delivery, but it came quite quickly. Ive never been so happy with a mattress and going to buy one for my elderly Mother who also has back pain. The comfort and support fro the mattress has definitely helped my sleeping pattern and eased the pain i was experiencing sleeping. The quality of my sleep has improved and the difference between sleep with Koala Plus Mattress and my old mattress is simply amazing. The mattress takes about 72 hours to harden up after taking it out of packaging so expect the firmness to increase during the first three days after opening. I also needed to use their customer support team who was amazing and answered my questions quickly and provided the extra help/support I needed. I had been looking at the Koala ads on facebook for awhile and glad I chose them, I had about 4 companies I Was looking at for my new mattress and glad I choose Koala. 100% recommended for a good nights sleep and for anyone who needs a mattress that doesn't have any sag points. No matter where I lay on the bed the firmness is consistent and it can handle two people in the bed easily without having that annoying problem of sag and drop. Thanks heaps to the Koala design team on this one, the plus is definitely the mattress for back pain and providing a better nights sleep.

I switched to the Koala Plus mattress during my pregnancy and it’s been a promising choice. It feels comfortable, supportive, and has a premium quality finish — I do sleep well on it. The only downside was a strong smell initially, which lasted a few days and made it hard to use the room at first. Also, the “bouncy-friendly” feature feels a bit… Read more

overrated as I can still notice some partner movement.

Overall, a comfortable and well-made mattress with just a couple of minor drawbacks.

Koala have amazing customer service! The mattress itself is pretty good, just firmer than I expected. However I was sent out a free mattress topper to help cushion my sleep after I phoned them inquiring about why it was so firm. Show details

I must say this mattress was nothing like I've owned before. I did like the feeling of being supported without springs and I was happy with this mattress. Unfortunately, it wasn't liked by my husband. We're not quite sure why his body didn't respond as well as mine to the mattress but it's not for everyone. Show details

had a pet mishap on the bed. Even with a mattress protector it somehow got all the way through the koala topper. The topper is constructed in a way that you can only “spot” clean. This should be able to be properly cleaned. Then, because it is a zipable removable topper you’d expect to be able to replace it. Nope. I find this a bit consumer unfriendly

Not bad but I’d consider further options

This is now our second Koala Plus Queen Mattress - we loved the first one so much that we bought one for the holiday home too. It is the only mattress we will ever consider buying and eventually they will be in all of our bedrooms - seriously the best nights sleep, particularly with a restless partner :) Show details

I recently purchased the Koala queen mattress and I couldn’t be happier! It’s incredibly comfortable, supportive, and honestly the best sleep I’ve had in ages. The quality is amazing, the setup was easy, and I noticed the difference from the very first night. If you’re thinking about upgrading your sleep — just do it. Absolutely worth every cent!

We love our new mattress. We love that it arrived in two easily unpacked boxes. After unpacking we left it to air and rise for about 36 hours. We love that it has two choices for the feel of the mattress and two choices for the temperature. We love that we found the mattress easy to manoeuvre onto our bed frame and we love that we find the mattress so comfortable . Many thanks to Koala. Show details
