We had our Raspberry Hyde & Sleep in firm, after 18 months we got Homeserve to come out and inspect it, faulty due to dipping. Did not take bed cover out at Dreams as all mattresses should last at least 8 years which is what I told them! Could not get money back but could exchange it for another one, old mattress being taken away, no cost for this or delivery fee. Make sure you get Homeserve to come out to inspect it and then go to Dreams with the report!
