Brought 1 year ago it was initially very comfortable , but start to build up a ridge down the middle and then started to sag on both sides .we asked dreams to review as we werent happy , they sent a person to review who said the sagging didnt hit the criteria for a faulty / return. We are both now suffering with bad back and necks each morning because it is like lying on completely un even ground. Extremely disappointed. I will never buy from Dreams again . Is there a way of publishing all of these comments on the Dreams website ' everyone seems to be reporting the same issues .
