After spending hours reading about all the different mattress in a box reviews, i decided to give this one a go as a starting point as the price was incredible good. The mattress was delivered quickly and i was surprised with the quality of the item. I instantly loved the mattress, had a real good firm feel and i had a great night sleep for months to come. My usual lower back pain all but disappeared and i couldn't of been happier.... until..... About 8 months in to owning this i started to notice a sore lower back more often than not, which over coming weeks/months got worst and worst. My wife also started to get really sore neck and shoulder. It wasnt until we went camping for a week and we were surpised how after a couple days our pain had dratisacally reduced. ... MoreAfter spending hours reading about all the different mattress in a box reviews, i decided to give this one a go as a starting point as the price was incredible good.

By the end of the trip we were pretty much healed, until we returned home and slept another night on the ZZZ Atelier. Pain back again and we now fight over who is sleeping on the floor on the camping mattress. About to go buy a proper mattress from a bed shop. Although this comes with 10yr guarantee this only covers massive indentations or major faults, not a general loss of support. My wife and I are both under 70 Kg and it didnt get too much of a work out with us having young kids if you know what i mean. If youlooking for a 6month mattress this is great... if something long term id spend a bit more and get some longevity. I was going to give it more stars if it wasnt for the lack of replacement under the warranty.

I have purchased 2 types of queen sized mattresses: Firm (with extra top layer) and this Extra firm (for the wife and kids). After letting it expand for a week, the top cushioning is slightly loose and can be slightly shifted around. Some others have complained about it, however its not a big deal you will put a mattress protector and won't shift around as you sleep on it. There is just enough padding there to make it comfortable and not feel the springs. It is definately firmer than the standard firm mattress and my wife hasn't complained once! (and that says alot!) I would like the edges of the mattress to be firmer, especially because they don't have size cushioning and when sitting on the edge it feels not firm enough. It is surprisingly heavy for a mattress and ... MoreI have purchased 2 types of queen sized mattresses: Firm (with extra top layer) and this Extra firm (for the wife and kids).

This mattress is extra extra firm which I wanted and I am loving it. I had a back pain from my previous medium firm mattress and as soon as I started sleeping on this mattress I am having great sleep and my back pain is gone. One important thing for buyers is this mattress is only one sided so you can sleep on one side only so you cant flip the mattress on the back side, however I am happy with it. Quality of this mattress is great for that super cheap price.

I already knew the corners would sag but the rest of the mattress has been great. Definitely firm enough for me. If it helps, I weigh 73kg, I am 170cm tall and I'm a back sleeper. The Queen size is good enough for me.
It is very good product. It is very firm which I want. It is not very hard when lie on it. It is just fine. I am going to buy one more for my granddaughter later. She absolutely needs it. It is good value. The quality is good , too. But the fiber material in the 4 sides should be used high quality one. It looks no good.
Its a very good mattress and for a very nice price! I'm glad I have ordered it. I recommended it to a few colleagues as well and they are all happy too. I wanted a super firm mattress to give my spine enough comfort at night. I would not say it's the most firm mattress I have ever slept on but it's good enough. I have made a mistake when ordered a mattress in a wrong size. I would like to thank the shop support people for resolving my issue fast and at no additional cost. Easy and fast communication.
Its very firm, exactly what i wanted. No pillow top, my opinion pillow top is useless, it out of shape w ont stay in same place very soon. Compare to the furniture shop , their firm mattress is still soft and cost lot more. I like it because im used to sleep on firm base, its not for everyone, if like soft mattress then its wont suitable. Very good price and checp delivery fee, my local furniture shops charges three times price for some brand and $75 for delivery. Im very surprised how good this materess is for the price. I only had it for a month so wont be able to comment on how long it last .
Bought this double mattress as my first Mattress in a box after going through other reviews. Been using it for 3 months now. I am impressed by the timely delivery and product quality. It iis firm to my liking as per description. The reason for 4 stars is that it is slightly shorter 2-3 cm than product description dimension. I'd ignored it but there is a clearly visible gap in bed frame and mattress ends.
We have got our mattress last month, since then its been a wonderful experience sleeping on it. I did try many of the online box mattresses and i have had issues with most of them, they were too soft which caused a back pain and uncomfortable posture for the rest of the day. After reading lot of positive reviews about ZZz i went ahead and placed an order for the super firm mattress. Its truly super firm and i have got rid of my back pain since I started using it. I highly recommend this mattress for anyone out there who is looking for a new and comfortable mattress.
You guys MUST buy this mattress. everytime i had a sleep with my previous one, i got the pain on my back-waist but after i bought this, it is completely GONE!! Very reasonable price and great value. Very very firm as well. i already recommended to my friend to buy this. i think it is very worth it to buy this product more often rather than spending a couple of thousand dollars to keep it for long time! very very very satisfied so far.
