I have ordered a mattress from Dreams with the above spec I outline in your question title bar. Meanwhile I am curious about three interesting questions that you suggest to one of your Q&A messages dated May 2017 by a gentleman who was contemplating buying a bed of the same Flaxby range from Dreams. You ask him to ask exactly what DNA springs are? Ask what the GSM is and also, what is the actual makeup of the Resilient white fibre? So now, in my case of already paid for and waiting for delivery of my said mattress, what do I do with the information they do give me when I ask? If it's just hype or not to spec how do I know as I have nothing to measure it by? I am just wondering if I have made a great error in buying this expensive mattress and worried I might have had the bedcovers pulled over my eyes ?.... Please advise me further however, they do not under any circumstance offer a refund so I'm stuck with buying one of their beds regardless. I would have preferred a normal flip over tufted anyway but my hubby really wants a quilty pillow top. Please help!!! Thanking you, regards.
