I bought it about a month ago. First I went to the dreams shop, there was this computerised bed that lay on and it tells you what type of mattress is best for you. It indicated for me the medium softness. I did try a few and I instantly knew medium would be a disastrous choice, as I tried a few before on a couple of occasions and I had a back pain, either after a day, days or weeks.
As a result I bought a firm one which I sleep on very well, although I was a bit disappointed with a top layer, which is not as firm as I hoped it would be.
I then bought a firm 2iches thick foam, and now I sleep like in heaven.
One star off for my disappointment. The Dreams needs to come down to earth with some of their products. I can see people complaining about the back pain, and this is due to the mattresses being way too soft, which is soo unhealthy and unnatural.
