After roughly 4 years and lately suffering from bad sleep, I complained to dreams they sent out an independent contractor for insurance assessment and I have been told that the natural dip in the centre of a double mattress is natural ware and tare ! What a load of rubbish it's only dipped in the middle & you can feel the springs through the top padding layer ! Declined insurance claim !!! Trading standards it is then. DREAMS VERY POOR AFTERCARE.
