Thoroughly recommend buying one of these mattresses

We were sceptical about purchasing a mattress online, but so glad we did. We received our mattress promptly, which was great, as our old one was on its last legs and sleeping was painful. When we placed it on the bed, we were concerned as we are used to a hard mattress and it seemed quite soft, but we have been so happy with our purchase. Since sleeping on our new mattress, we have had improved sleep quality and our backs are not hurting in the morning anymore. There is no partner sleep disturbance. The only warning to others, is that the mattress is quite heavy and difficult to manoeuvre. We would purchase another one if they did mattresses for caravans. Show details

Love our Ergoflex Mattress!

We recently purchased an Ergoflex 5G mattress. We are very happy with it. It feels quite new every time we go to bed. The mattress helps distributing body heat evenly, making it quite comfortable and relaxing for your partner. For the quality it is offering, the price is quite reasonable. We loved it completely. Also, the memory foam has helped me in relieving bit of lower back and knee pain due to its structure and shape retention quality. We love it completely. Highly recommend, if you are in the market to buy a good quality mattress with lower impact on your pocket. Show details

I honestly didn't know what to expect when I bought this online, but the 30 day trial gave me enough comfort to try to it out. And I am so glad I did! This is the best mattress I have ever owned! I can not wait to get into bed each night. I highly highly recommend this mattress to anyone who will listen! Show details

Ergoflex are the best!

We purchased our Ergoflex after rave reviews from a friend. I've had 2 previous back surgeries and would wake in the morning in utter pain. After purchasing the mattress it did a week or two to grow accustomed to the new feel. However, within 2 weeks, my husband and I were having the best sleep we have ever had, waking without any pain. It's been 5 years now and we couldn't recommend Ergoflex any higher. Their customer service is incredible, delivery smooth and now we all sleep soundly. Going on holidays, we miss our bed!! Thank you!! Show details

Great mattress

Finally, a mattress that is improving my back pain.. The mattress felt somewhat hard for the first week or so but if you persevere, you will be most impressed at how comfortable it feels and if you’re like me and suffer a bad back.. give this mattress a go - you will not be disappointed. Show details

Quality Mattress and helpful staff

I absolutely love Ergoflex mattresses. Have been using them for over 10 years. Have purchased 5 in the last 10 years. I recently moves Overseas and realised I needed a bigger mattress. I contacted Ergoflex and the staff ( Matthew) could not be more helpful in helping me choose a size and arranging delivery to Singapore. ( arrived within 5 days ) Will definitely purchase more in future. Show details

We love the Ergoflex mattress that we've had for longer than we want to mention here (and it's still going strong...). There was really only one choice when we decided to get a bigger bed, and we're not disappointed. Getting out of bed to go to work has never been so hard!

We're now 6 months in with the new one - every night I get into bed I appreciate this mattress. Many years back I suffered a back injury, which is why we got an Ergoflex in the first place (recommended to us by a friend who sustained a very serious back injury, and swears by them now!). My wife and I both find this mattress really helps. Show details

Upgrading my egoflex mattress of 10+ years to a new and bigger one

My Egoflex mattress once again has been the perfect choice.
It has had a positive effect on the comfort of my sleep, and I feel I get a much better sleep then my previous egoflex mattress.
I had my previous mattress for well over ten years and it was still in great condition, but It was time to get a bigger mattress. I gave that mattress to a family member as the durability lasted and still had many years I think. A lot has changed and it’s even more comfortable than my previous mattress. Show details

I recently purchased the Ergoflex king mattress and I am extremely impressed with the quality and comfort of this product. From the moment I lay down on it, I could feel the difference in the support and the level of comfort it provides. I have had the best sleep since I started using this mattress and I wake up feeling refreshed and rejuvenated. The memory foam molds perfectly to my body, providing just the right amount of support for a great night's sleep. I highly recommend the Ergoflex king mattress to anyone looking for a high-quality, comfortable mattress. Show details

Not bouncy just firm enough

This is our 2nd Ergoflex mattress. We loved our last one, gave away to someone who needed it, bought a new one and it is just as good if not better. No tossing and turning or bouncing my husband to the ceiling. The mattress stays cool too. Highly recommended. Show details

Absolute delight to sleep on!

Ergoflex King has been a game changer for my wife & I... mainly because our Great Dane can jump in during the night and not wake us up. Not only because of the space, but also the Foam's ability to absorb the movement of 60kg+ jumping on the bed. Absolute weapon of a mattress Show details

Sleep Like a Dog

Easy to order, arrived on time, had a few queries that were answered straight away. Easy to unpack. Took a couple of days to get used to it as it feels quite different to what I was used to, which I was told would be the case. Love it. My only problem is keeping my red heeler off the bed as he loves it too. Show details

Finally getting a good nights sleep

This is a great mattress, we were looking at a Tempur mattress but where not keen on paying over $4000. A friend recommended Ergoflex 5G as he had been in the same situation. We have had our mattress for 3 months now and it supports the body perfectly, we are sleeping the best we have for a long time. Great value for a quality mattress. Show details

Questions & Answers

sand_rahh · Memory Foam Mattress King


Can you please confirm how the customised bed base is constructed? Is it slats or a boarding?


Ergoflex   DM   

Hi, thank you for your question. The bed frame consists of slats with a fabric covering to provide the perfect platform for a mattress. Kind regards, Ergoflex Australia.

Phil · Memory Foam Mattress King

I purchased a Queen mattress in 2014 and now purchased a King in 2019. In the newer 2019 model my mid-lower back bottoms out the memory foam as soon as I lie on my back, whereas the 2014 one felt firmer and took longer to mold. I'm waking up in the night a lot to move around because it's hurting my back. Consequently I don't know if I'm getting the support I need and am waking up with a sore back. What's changed since previous models?

Brooksie · Memory Foam Mattress King

How do we spin this mattress without killing ourselves because it has no loops/ handles or lugs like normal mattresses? We are in our mid to late 70's and I see a major problem looming.


I don't think you are supposed to.


It is recommended by the manufacturer. I'm not saying to flip it over but to spin it top to toe
