Originally developed by the world's leading scientists at NASA, memory foam has now been adapted to provide the ultimate mattress solution. Memory foam reacts to the warmth of your body and contours to your shape in any position, supporting the areas that need it most allowing you to drift off into deep, high quality sleep. By doing this the pressure of your weight on the mattress is spread over a larger surface area which reduces pressure points and improves blood flow. Memory Foam will always remember its original shape and return to its normal size after each excellent night's sleep.

I am very tall and weigh about 15 stone, and this mattress simply does not offer enough support for my weight.
At first it seemed comfortable enough, but after a few days I started to notice that I was waking up in the morning feeling that I had 'sunk' into the bed, and because of this my joints felt stiff and sore.
The amount of give in the mattress feels wrong to me - it is very soft and although the elasticity does mean it regains its shape, I really felt that it was giving too much whilst I slept on it, and should be firmer. I have recurrent (minor) problems with my upper back following an injury suffered a few years ago, and this mattress did not help with this. With somebody else in the bed the problem is worse, especially if they are much lighter to you - the mattress does not hold its shape very well and the weight distribution goes awry.
Its size also makes it very difficult to cover with a sheet - you need something very big indeed if you want it to be tucked in and nicely secure.
It feels and looks very cheaply made and I can't help but wonder whether the more expensive memory foam mattresses available offer a firmer or better feel (I haven't tried any so I cannot compare this to other memory foam mattresses I'm afraid). It is also much warmer than conventional mattresses - uncomfortably so in fact. This is apparently a known thing with memory foam mattresses, but many have a special layer to conduct heat away from the body - this one doesn't, or if it does it isn't very effective!
If you haven't tried a memory foam mattress before, I would suggest going to John Lewis or Habitat and trying one out first. I personally feel that this one is not of sufficient quality for me, and I have reverted back to an old pocket sprung mattress which is much more comfortable and spreads the weight more evenly.
I wanted a very firm mattress so this is ideal. I have tried the expensive memory foam mattresses in bed shops but were all too soft (A bit like like sinking into a marshmallow?) and did not like them. I was worried this mattress would be the same but it is great, very firm. I had awful back ache with our old mattress but since sleeping on this my back is great.
I saw the comments about smell but i only noticed a slight plastic type smell as the product was unpacked and expanding. This quickly dissapeared the next day. No further smell now.
My 14yr old daughter loves our mattress so I have decided to eventually replace the mattresses for the whole family with the same product.
The 12" deep mattress is very high on top of a divan base and I needed to go out and buy new sheets with a deeper fit as my standard sheets did not fit the depth. If you are not very tall you might find it difficult to get on to the bed however it is fine for me as I am tall (5ft 10"). I think the 8" OR 10" deep version would be enough for most people. My husband and I are very heavy people and this mattress is absolutely fine, when each of us rolls over in bed the other is not disturbed.
The pillows included in package are very solid and not comfortable to sleep on but very good as a back support when sitting in a chair.
I've got a dodgy lower back and can suffer badly from a sprung mattress. This mattress is very comfortable and supports all the parts of the body during sleep. The price is much cheaper than most of the others I'd seen - so was a bit dubious when I ordered it but I'm very pleasantly surprised so far.
