The comfort return guarantee if you have the tiniest little mark on the mattress although u have 40 nights trial is a load of rubbish. The customer service side is not helpful at all all they want is your money then after that they are not interested. I’m am going to take this further and advise everyone to be careful when purchasing a bed from dreams. Lack of customer care and after sales are not interested although u have purchased all the insurances and extras that’s sold to you. If u have a problem you will be on the phone for hours to get through to a customer advisor that does not careless. I will be taking this matter further through the furniture obadsman as Dreams are not interested should be called “nightmares”. After spending nearly 2000 pound there is no complaints department and not interested if you have any slight problem. I will never go back again to this company. The term 40 nights is misleading and not explained at all just another sales scam.. be careful and shop around,
