    Golden Review Award: 2 From Our UsersI bought without cover as I already own mattress cover. Yes it smelt pretty awful when it arrived, I aired it for 48 hours before I slept on it and it then took another 2 weeks to completely fade. However, other than that, perfect for price, very comfortable. Excellent value for money as I didn’t want to invest in a 1000 new mattress just yet.

    Love this mattress topper. Takes less than 1 hour to expand to full size so don’t panic when it comes and you think it’s too small like I did. Very good quality and very comfortable. It arrived 2 days after I ordered it and it wasn’t meant to be delivered for at least 2 weeks later. Highly recommend it.

    Great purchase, it changed my life! This topper would make any hard and uncomfortable mattress a perfect one. It is soft and warm, it is so thick feels like you’re in a cocoon. One thing I would mention, when it is new has a very strong unpleasant smell. Open it and leave it somewhere to air for a few days and the smell will dissapare.

    Golden Review Award: 4 From Our UsersWell, I was very surprised as I was expecting really thin-ish weak foam but its very thick and soft and sqwishy. I am 7 months pregnant so struggling to sleep hugely at the moment we bought a kingsize and fits well. The smell is not as bad as people say too as this put me off at first buying, definitely worth the price and transforms any condition mattress our mattress was new but very spring like as chepish. I would recommend this product especially for the sake of saving 100s on a mattress. My partner is very happy with it. Delivery good as always.

    I bought it so that my bf can sleep over at mine sometimes as I only have a single bed in my uni accommodation. I just put it down on the floor and it is really comfy and far better than a mattress I have on my actual bed.

    When we finally received the mattress topper nearly a week later. We put it on the bed and yes people have mentioned the funny smell this does fade in time. I can say for the last week both my husband and I have have the best nights sleep for a long while, we wake up in the morning with no aches or pains best purchased in a long time. Just ordered one for the spare room .

    I recently spent over 700 on a new ‘special’ mattress. After sleeping on it for a month, my back and hips were painful and negatively affecting my sleep. I bought this product with my fingers crossed, 2 days later after receipt, the pain was gone.

    Correct size, super soft and comfortable, gives sleep a a whole new quality.. A little hot to sleep on for my personal taste but that is just the character of the material. Smells a little bit but having a mattress protector on takes away the smell and the feeling that you sink in a bit too much. Love it.. i do recommend.

    My existing matress was nearing the end of its days so I got this to give it a bit more life. Plus i’m too lazy to mess around getting rid of an old matress. This has done the job perfectly. Fits the bed exactly & is incredibly comfortable. Recommended.

    Got this while pregnant as kept getting sore back with normal mattress. Very comfy but does make bed a lot warmer so may need a thinner duvet or you will cook! No issues with smell as some reviews mentiond. Is quite expensive

    Amazing product. Came fast. Yes it does smell a wee but but it goes away fairly quickly once you sleep on it a few time and you get a great night sleep out of it. Like a whole new mattress

    Delivered before it was due..no smell.. I laid on the bed and left about 4 hours to settle…. at first due to the way it’s packaged it looks a funny shape and as though it’s not quite going to fit. But 4 hours later it had spread and I made the bed. Best nights sleep in years. Perfect depth at the 3″. Definately need some extra deep sheets though as I had to fight hard to get mine on. All in all very happy..great bargain!

    Have a new and rather firm bed in our new house so purchased this topper to try and get it comfy. It arrived promptly and was well packaged. The quality was exceptional and the memory foam was lovely and thick. Brilliant value for money and better than anticipated.

    Excellent – fits over my mattress perfectly, doesn’t move about and provides a soft, cosy cushioning for my arthritic hip. It took a few nights for the rather odd ‘new’ smell to wear off, but it didn’t interfere with my sleep.

  44. GarryLocklear says:

    Very pleased with everything. The mattress is lovely and was delivery on time too! There is a faint smell from the mattress, which is to be expected, but just air before you cover it and it soon fades. I would definitely recommend this product and the company.

    Golden Review Award: 2 From Our UsersWell, I’m finally getting some decent sleep on our Ikea mattress, which DH bought by mistake, thinking it was memory foam but which turned out to be very firm latex. He liked it, as he’s much heavier than me, but I was getting out of bed with aching ribs and a sore back every morning. That made me very grumpy. Now, with this topper, the mattress is still supportive enough for him but also soft enough for me. No more morning aches and pains. I have another thin mattress topper and a mattress protector on top, both with elasticated straps at the corners. These prevent the memory foam from creeping around the bed, a problem several users have reported. An added bonus is that our bottom sheet now fits properly, so no more sleeping on a wrinkled sheet! The smell from the topper is noticeable at first but it soon dissipates. I recommend this product.

    Is definitely memory foam, comfy, right size, arrived quickly. However, it could be cut straighter, slightly wonky on one side and has a definate smell, like paraffin.

    I wasn’t expecting too much for the price paid but this is excellent – no bad smell as other reviewers have said – put it on the bed and waited a few hours and it expanded to fit perfectly – My husband loves it but it took me a few nights to get used to it – you do need to have very deep sheets if they are fitted but overall very pleased

    Actually seems to work- my wife’s back is much improved and by extension, so is her sleep. What other people are saying is right though, it does stink. I’m hoping that the smell will eventually go away as its really not very pleasant- very chemical solvent smell

    Item arrived on time with very quick delivery. This isn’t the NASA type memory foam topper as i already have one of those so I know the difference, however it is very comfortable. I suffer with my lower discs in my back & also my hips and since purchase I have managed to get a very comfortable nights sleep with no aches and pains when i wake up! BEWARE though, there is a very strong chemical smell when it’s on the bed, BUT this has started to disappear through use. DEFINITELY worth the buy.

    I love it. My mattress was getting alittle tired of itself, but buying this to put on top has made me feel like its a totally new mattress. Love getting into bed on this!! Reason for 4 stars is that it does look a little worn in the 2 main areas myself and my husband obviously sleep and I only have it 6 months. I flipped it over though and hopefully this will balance out the wearing.

    Excellent product. Arrive quickly, well packaged.
    Worth every penny and more. Have had for two weeks and cannot believe how good the mattress is and what a difference it makes. I sleep better than I have done for years and I wake up feeling well rested and without feeling stiff. It has helped my lower back enormously. If it only lasts a year I would by another one again. It would work out at 1 a week for a great nights sleep – worth it I’d say! Follow instructions, open and leave to breath for a couple of hours, it says to use straight away as this will remove the odour. We did exactly that, the odour was minimal and the next day was not noticeable. You will need deep sheets.
    I had been suffering with my back for months following a car accident and having physio. I was waking up every morning so stiff it was taking me a while to get moving. I had been looking for a topper for a long time and at 100 plus just didn’t know what to do. A new mattress was a big expense and without guarantee. So I looked at the other comments about this and for 50 I thought it would be worth the risk. The risk paid off!!

    I recently bought a new bed and mattress, but dissappointingly it seemed to be causing me constant back and shoulder pain due to being a bit too firm. I went for this mattress topper mainly due to the price and thickness, and I am not dissappointed. It does make the bed rather hot to sleep on, but my back pain has gone so I am pleased overall!
    Probably best to use a super king size flat sheet on the bed after putting this on though. It’s difficult to stretch a king size one over it and the existing mattress.
