The mattress is a dream! – Excellent experience and the mattress provides great support and comfort for a lovely sleep! Back issues have diminished and the quality has provided a mattress that still feels like new.
Very Happy Customer – Very comfortable mattress - prior to having this mattress I had a sore back and i no longer have this with the new mattress. Very happy and great value for money. Show details
Body impressions after 6-8months – We have had the mattress about 10months - delivered 11-MARCH-24, but have only been using it 8 months due to house renovation. The Ice-tek surface is very annoying as the sheets slip, so we find ourselves constantly having to refit. I have noticed over the past couple of months, wells are forming where we lay. the middle has now a noticeable… Read more
ridge/firm area. I understand that there will be some moulding of the foam layers, but this seems worse than I would have expected for a fairly expensive mattress after only 8 months use.

Happy with the sleep after 12 months use – We purchased two queen size mattresses about 12 months ago and have found the mattresses extremely comfortable. They are very supportive and improved sleep quality. We have noticed some "sagging" in the pillow top (refer photo) when we remove the sheets, however, this has not impacted comfort or quality of sleep Show details · 1
Was good till now – Bought the plush version and comfort is great. Sometimes it can get a little too soft on one side more then the other but the main problem I found with this mattress after 10 months from purchase date, that there are holes developing near the circular stitching where the fabric that they used has stretched (probably due to weight and I’m only… Read more
68kg) and can start to see the fabric/ the layer underneath poking through. Have contacted the store where I purchased the product, waiting on a response from the manager one the next steps. If it’s not fixable, I’m worried these holes will get bigger over time causing the product to be further damaged and unusable which is a waste of money to not be able to use it for the standard 5-10 year warranty/use of a mattress life span. Also worried if we exchange for the same mattress this issue will arise again. So quality and durability of the product has me worried for long term use.
Hi Jane. Thank you for your feedback. It is… Read more
Poor quality – A bit under 2 months old and the stitching is already coming undone on the top layer. Mattress is already sagging way beyond the 4cm allowed from new mattress setting in, I have rotated the bed every week as instructions recommend. This mattress cost me $2200 and I have honestly had a better nights sleep on a $300 premium foam caravan mattress… Read more
from Clark Rubber, At least that lasted 2 years before any sagging. The Icetek layer is marketing rubbish, Does nothing for cooling as the bed is still memory foam top layers trapping heat. Extremely disappointed in this bed, Never spent more than $1000 previously on any mattress and thought this would give me the best sleep ever, It has turned out to be a nightmare, Rolling over every 40 minutes because my hips have sunk that far into bed it is causing hip and back pain. Bed Buyer advice was also very poor, I bought a medium on their recommendation for side sleepers for support but it is even worse than a cheap very firm mattress which costs 1/6 of the price. It has a 10 year warranty which is one of it's good points but it looks like I will need to use it in the first few months with the stitching and sagging issues. For reference I am 47 year old male, 6ft tall and weigh 85kg, If you are heavier and sleep on your side I would take bed buyers advice with a grain of salt and avoid medium it is too soft and you will sink even more than me, Try a firm first and go from there. If you weigh under 80kg medium will possibly be the right choice for a side sleeper. Best of luck to you all, Buying a bed is harder than I thought!
4 months later, Bed is alm,ost unusable from sagging causing hip pain, I have to sleep right on the very edge of the bed where it is just firm enough and less sag. This company is a scam, Been down to the place of purchase and they also don't want anything to do with you after you hand over the money. I went back down and tried all of the firmness levels of this bed in the showroom and even the plush doesn't sink like the bed I received, It is nothing like the one's on display. For a warranty claim they ask to take photo's to show sag yet won't allow you to lay on it or press down on it, How can you show sag on a memory foam mattress without actually using it? memory foam springs back up and hides any flaws underneath.

Perfect choice – Selected after researching mattresses online. Was helped by a lovely retail assistant who gave us advice on a variety of different mattresses. Happy with our choice Show details · 1
A GREAT NIGHT SLEEP – We are very pleased we chose the Silentnight black Onyx mattress, we were going to buy the plush which felt really good at the showroom but we decided on the Medium and have no regrets. It's a very comfy mattress, great for out backs. Have not felt the cooling effect as yet because it's been cold. Very happy with our purchase! Show details · 1
Very comfortable mattress – We brought this mattress based on our instore experience, & on reviews. We are finding it very comfortable, & we sleep well. Our only issue is that the mattress is heavy. Show details · 1

Very bad sagging mattress – I bought this premium mattress in Dec 2022. Since the beginning I notice that the mattress is sagging in the part where I sleep. I am only 80 kg so not heavy weight. I thought it will settle in time. I also rotated the mattress after 6 months but the issue persisted. Now after few years the mattress dips so much that in the middle of my sleep I… Read more
found myself in a big dip hole and I have to shift to another side of the mattress at night. I invested in a premium mattress so I can improve my quality sleep but instead I have most of the time sleepless disrupted nights and sore back. I am very disappointed.
Strong Smell – Strong smell, not sure what is this from, may be the use of rubber and glue. It has lasted over a week since we received the mattress, We still have to sleep on our old mattress for this week due to the smell. Show details
Lower back issues – Since we bought this medium mattress I have had a sore lower back & I find it hard to get comfortable & go to sleep. My partner mostly sleeps on her stomach & is fine but it’s terrible for me. We can’t exchange or return, so looks I have to put up with it. It cost us what we consider a fair amount of money. Disappointed!!! Show details

Worst mattress I’ve ever slept on (for 6 months at least) … now it feels good – I should’ve kept the koala mattress after all this is by far the worst mattress I have slept on, I can’t believe for the price I paid that I’ve had such bad sleep, I have even dreamt of how painful this mattress is. Firstly I accept it’s firm but there is absolutely no give where my shoulders are so my arms end up numb, it feels like I can… Read more
actually feel the springs. If I sleep on my back my lower back ends up sore because it feels like there is a dip already and this from rotating the mattress weekly. At least koala offer a return as I bought from beds n dreams I’m stuck with this lemon of a mattress. I also felt mislead by the sales rep, I was told that the medium was not in stock and it would take 3 weeks to order it in. I did mention that online I thought it said 7 to 10 days to deliver to my address and she said no it would be 3 weeks. I’ve checked again and it definitely doesn’t say 3 weeks. I also just checked the mattress online and the store charged me 2819.00 online the mattress is 2579.00 … disgusting that I was overcharged $250 more!
Updated, to fix the firmness issue I used a cheap underlay which worked well in winter but was getting too hot so I removed it. I was pleasantly surprised that after 6 months the mattress no longer felt rock hard where my shoulders are so I think this one just takes longer than 3 months to soften up a bit. It’s more medium firm now rather than rock hard so perfect….we’ll so I thought after 1 month pain again in my shoulders and the indentation on the mattress is ridiculous. What a nightmare of a mattress.

Lovely mattress – This is a lovely mattress. I choose the cooling mattress as I am a hot sleeper. The only thing I wish is that the mattress was a little softer on the pillowtop. I feel it is a little too firm for my liking. I was concerned that the soft would be too soft and leave body indentations something I absolutely hate in mattresses. Show details · 1
An excellent mattress – This is an excellent mattress. It isolates individual sleepers well and is very comfortable too. The only negative I have is that the mattress is very heavy, making it difficult to change fitted sheets. It is currently being used on a timber bed frame, which exacerbates the weight issue. A different base might be better. Show details · 1
Not the comfiest – We got the medium and it is soft and both sides sink in. I sleep in the middle on the firmer Ridge when my partner works night shift. We changed from a $7000 king koil which was very similar but happened over a longer time. The sales man said the sinking would not happen to this one like it did on the KK. We are both 100kg which probably doesn't… Read more

Can’t wait to go to bed each night – This is by far the best mattress I have ever slept on .. It is so comfortable and soft yet supportive at the same time .. it is extremely heavy and more difficult to rotate but I expect that is due to the high number of springs and quality build .. I have slept better since purchasing it a month ago than I have in decades. Show details · 1
Amazing Mattress! – Nothing but good things to say about this mattrrsss. Before deciding on the silent night we tried many other mattresses from king koil, snooze and Sealy. I have to say the silent night is a quality matress. The quality appears top notch, even though we have only had it for about a month now. Not the cheapest matress but certainly very… Read more · 1
comfortable. I'm not really sure what more I can say other than, if you want to part with some decent coin, this mattress will not disappoint.
A good mattress for back injury – I have lower back pain for nearly 2 years. This mattress helps a lot to relax my back. My back feels super relaxed by sleeping on the mattress. I definitely recommend it. Show details · 1
Lovely cool mattress – If you're going to spend 1/3 of your life lying down it's worth investing in a great mattress. This is the best I've found. It is blissful to lie on and I sincerely wish I could spend more time there. It is lovely to have a cool mattress, even in winter, I love being able to find a cool place to put my aching knee. Definitely recommend this mattress to my friends. Show details · 1
Great mattress – I am very happy with the quality and comfort of this mattress. I previously always had a sore neck from my old mattress and tossed and turned a lot to get comfortable. Since having the new mattress my sleep quality is much better, I also don’t get hot like I used to. Very happy with the brand. Show details · 1
This is my second review over 1 year later – First got this mattress is was comfortable and I was happy with my purchase, I’ve had a small problem with feel of bed but is now being rectified by Silent Night and I thank them, took a while to arrange but at no body’s fault except for Covid making it hard to have it looked at, Great service from bed technician who looked at bed.

Very comfortable. Almost zero disturbance from partner's movement – This mattress is so comfortable! My partner and I typically sleep on 'medium' matresses, but we went the plush with Onyx and after a month it's proven the right choice. It is definitely firmer than most brands 'plush' range. The new mattress smell went away after a few days. It is heavy, but not too heavy for me to spin by myself. You will need extra deep sheets - which can be pricey. Show details · 1
Cool and Comfortable – Quality matress comfortable and cool.Am waiting for delivery of my new base to complement it.No to rotate regularly, matress has maintained shape and conformity.Highly recommended product you get what you pay for. Show details · 1
Best sleep in years – This is the most comfortable mattress I have ever bought. My sleep has improved significantly & I don't wake up with a sore back any more. Best purchase, would not go back to another brand! Show details · 1
Great mattress. Most comfortable I have had – It is very comfortable and fits perfectly to your body. Love that it does not move during the night so I do not impact my partner. Best mattress I have owned Show details · 1

Amazing – I'm sleeping so much better. My fitness tracker is indicating more time spent in deep sleep than before and I am not waking up with a sore back like I was previously with my old mattress. Show details · 1
Awesome mattress that has improved our sleep! – We love this mattress! It has been a game-changer for us as I toss and turn a lot and it no longer keeps my partner awake. The support has been excellent for both of us as we both have injuries (back and neck) and have noticed that we no longer ache when we get out of bed. Highly recommend this mattress. Show details · 1
Terrible. I have been fooled by Bed Buyer – Terrible. Matress sinking in middle area. Only 2 weeks I started to felt back pain. I did complaint to both manufacturing and company. They just dismiss my complaints saying they are sure about their quality and they use covid as reason to dismiss my complaints. I should have known when I signed the unfair contract. They said 4 cm is normal body… Read more
indent. O..no. I should have known 2 cm down already señt you to phyisio for therapy. It just so complicated dealing with this company. No honesty at all.The end of the story they told me to sell the matress online. O..no I did researched and I can only sell second hand matress for 300 dollar. While I bought it 1700 including delivery. If i go with investigation then they will ask for a fee. It just not worthed. It just like dealing with liar.. you dont know whether they tell the truth

Geltop not as effective with mattress protector on top – It is firm as I have back issues Mattress is very heavy to turn around...... just be aware of this Mattress has sagged a fair amount It is more comfortable than other mattresses Show details · 1
Great Mattress – Excellent comfort and support. It took a while for the smells associated with a new mattress to fade, but it was worth the wait! My only issue is that it is virtually impossible to buy the required 50cm depth sheets to fit a double mattress. I have to use the standard 40cm fitted sheet which is tight to say the least. Maybe the manufacturer can do some commercial deal to have sheets manufactured to fit the mattress properly Show details · 1
Changed the way we sleep - and wake up! – After a lot of research we tried the Silent Night Onyx mattress. We’d read how good it was but tried to be impartial and had tried maybe 20 - 30 other mattresses. As soon as we laid on this one we knew it was the one, absolutely zero doubt from either of us. Since delivery we’ve slept better and both of us have woken with less pain, joints feel better. Highly, highly recommend. Show details · 1
MATTRESS IS NOT COMFORTABLE.. NOT FOR HOT SLEEPERS – Have waited for two weeks to submit this review to have a more accurate one. Bed is quite hot and the supposed cooling topper is very slippery causing the mattress protector and bottom sheet to move around under you. Tried the medium in store several times and found it to be ok. Our mattress arrived with a grease stain on it and it is way firmer… Read more
than a medium mattress should be. Sleep quality is very poor due to firmness and sheet moving around. Customer care were very help full giving me a comfort swap. The new mattress is softer but still very hot. The icetech top is useless when you have to fit a mattress protector. This bed is not for a hot sleeper. Also after only a few days there are quite large body indentations in it. Do not buy get poor value for money. The store doesn't want to no you if you have problems.
Love this deep mattress – Very comfortable, easy to turn with the base we have. Show details · 1
