Recieved my mattress in speedy time. Very heavy when rolled up. Easy to unpack. Has a strong chemical smell for the first few days with it being new then the smell dissapates. Realatively comfortable. Quite firm but can feel the springs. Not bad for a cheap mattress.

When I told friends and family i’d purchased this mattress, I was hit with a lot of funny looks and faces as if to say ‘that’s going to be terrible…’. However, I couldn’t be more pleased with it! It’s actually incredibly comfortable, and of really good quality. Some people may want to add a mattress topper to it, which you can pick up for less than £100, but the price of this is great.

I bought this mattress back in June 2023 and held off reviewing it until I had a good feel of it. The mattress is surprisingly comfortable for the price – let’s be honest, it’s not hotel quality, but it is quite firm and supports my back pretty well.
The biggest issue is quality; first of all, it does not look as good as in pictures – it has a much cheaper look when it arrives, and the material is paper thin – it seems a bit like a cloth rather than fabric. This leads me to my next point: after a couple of months, the mattress started developing cracks near the edge stitching (see pictures). I am not expecting it to last more than one more year.
Also, shipping was delayed by a couple of days, and as we were moving into a completely new property, we had to spend a couple of nights on the sofa.

I got this for my daughter as her previous mattress was just memory foam and rather thin, therefore quite uncomfortable on her new bed frame.
When this mattress arrived in its box I took it out and left it for 48 hours, after which it was fully decompressed and seemed to be pretty good.
For me personally I think it’s way too springy and soft, and doesn’t offer enough support for my back which needs a fairly firm mattress.
However, my daughter on the other hand loves it. She says it’s super comfy and she has slept better since getting this than she has in a very long time. I’ve also noticed that it’s stopped her wriggling so much in bed, leading me to conclude that this was due to her previous mattress not being comfortable enough for her.
It’s a good depth for the price too.
Over all, for a budget online mattress, this is pretty good.
The reason I’ve dropped it a star over all and for comfort is that it’s not for me, and softness got 5 stars because it is very soft.
Like I said though, it’s not for me and certainly not for everyone. If you prefer a firmer mattress this isn’t for you, if you like soft and springy then try this.
Ultimately it’s personal preference, so I’ve split the difference in star ratings and tried to give you a good overview from 2 view points.

I’ve never slept better. I was so sceptical about buying this mattress after reading some of the reviews about the noise and springs and firmness etc. BUT I am so glad I went with the majority. So far it is incredibly comfy, perfect firmness – and I get a bad back very easily when sleeping on new mattresses but I’ve slept like a baby. Partner loves it too. Very happy! When it arrives it was rolled up and I could see that it was a springy mattress and I was full of regret, however I left it a few hoirs to fluff up and WOW I am so pleasantly surprised! Best mattress, so happy with it!!

Being recently conflicted with the negative comments, I’m actually impressed with the quality of the mattress. We had a very limited budget & desperately needed a replacement and for the price, you really can’t go wrong. It’s comfortable, fairly thick and looks well made. It’s a lot more supportive than our previous mattress. So if anything, it’s an upgrade. The size was appropriate for our new bed base and overall, impressed and excellent value for money.

We decided to swap our double bed for a king sized & purchased a king size mattress in the process.
After looking at the reviews we thought this would be the perfect replacement, we placed it on our newly constructed frame and waited 3 days to give it time to get into shape.
When we slept in it, it was ok for my wife but my side you can feel the springs digging into you, not only that but the noise of the springs popping is enough to wake us both up.
I’ve had to scrap it & annoyed because it cost over a hundred pounds.
If you look at the photos also, it’s definitely not got what’s stated, recycled cloth and a bit of memory foam???
If you’re in the market for a new mattress, go for a slightly more expensive one, you get what you pay for unfortunately.
There maybe a few mattress that are fit for purpose in their stock but it’ll be your own gamble & absolutely don’t ignore the negative reviews…especially when they all state the same thing.
