With 3 zones of support and easily customisable firmness levels, you can be rest assured the New Koala Calm As Mattress hits the spot every single night.

Koala Calm As Mattress King - Lifestyle Slide

Adjustable firmness levels

What might feel right to your mate, doesn't feel right to you. That's why we've created our double-sided comfort layer that gives you the choice between medium-firm support and firm support. Just unzip and flip it to find what works for you.

Koala Calm As Mattress King - USP 2

Supportive edges

Calm As Mattress Queen - Lifestyle - 3 Zone Support + Multi-Layer Zoning

Support in all the right places

We have a firmer support base right beneath the hips that prevents your body from sinking into the mattress. This comes in handy when it comes to helping you maintain a healthy sleeping posture.

Uncomfortable but a great company to deal with!

The Koala Calm As Mattress wasn't for us but we had a great experience nonetheless. It arrived the day after ordering and was super easy. We had purchased one of the original Koala Mattresses years ago and loved it so thought we would upgrade to the Calm As Mattress when we got a bigger bed. Unfortunately we didn't like the feel of it, the medium and the firm side just weren't supportive enough and we kept waking up with sore backs each morning. The process of returning the Mattress was easy and stress free! They were responsive and helpful and the Mattress was picked up quickly and the refund was processed on the day. Although not the Mattress for us, purchasing through Koala was great!

Happy As

There may well be a better mattress but I haven’t slept on it yet. Super quick delivery (in SE Qld at least) easy setup. I’m a 6ft 3 inch, 107kg, 50’s male who predominantly side and front sleeps. Comfortable and supportive in both positions. I haven’t found the mattress to be hot. My wife is super happy as well. Koala will nag you with emails for a review (smile), but it really does deserve one.

Good value for money

The whole experience of buying, receiving and installing this product was very good. It was seamless and the set up video excellent. The only negative was the bed is a little too firm for side sleepers with swimmers shoulders. The support on your back is outstanding and very comfortable. We needed it to be a little more soft.

Calm As = Good Night Sleep

I won't lie but I was abit sceptical buying this mattress as I couldn't find much about it online due to the model being fairly new. However we had some friends who raved about the original Koala mattress so we figured why not give it a shot. This isn't my first mattress in a box experience so I knew what to expect, quick delivery, good communication and easy to set up but I'm sure your sick of reading reviews about the delivery and want to know is the mattress itself worth it. And the answer is....Yes! I have no hesitation to recommend this, especially since I am a side sleeper who struggles with overheating at night. Siince getting this mattress however I've had some of the best nights sleep I've had in years. The biggest pro for me is the lack of bounce/mattress movement from others to. This mattress seems to absorb most movements which is great when you and your partner go to bed at diff times or when one of you is a restless sleeper as it limits the impact it has on others in the bed. No mattress will ever stay completely cold as one would be led to believe by marketinf but it is one isthe perfect level of cool without overheating and this has also been a big win for our home. Cons - Theres not many really, it's definitely more pricey than entry level mattress in a boxes but for good reason as its well worth it. I havnt noticed any new mattress smells either so can't comment on that as I've seen others do. Probably the only thing to note is it's slightly taller so some tight fitted bed sheets may not work or may not have the appropriate coverage so just keep an eye out on depth when buying those.

Best purchase ever

I’m loving my new Koala Calm As Mattress. The first night I slept in it was amazing, when I woke up in the morning it felt to me like I had a back alignment done and I heard bits of body click into place. I love sleeping on it and so do my kids. Now I just have to get them out of my bed and back into theirs. I can definitely tell the difference from my old mattress and new one. Love the better quality sleep that I am getting. Makes all the difference. Can’t wait to see what it feels like during the warmer months.
