Cloud 9 is now Hell 1

I bought a cloud nine matress on 20 November 2010. It was highly comfortable for a few years, I turn the bed regularly and recently (starting about 2 years ago) the comfort is gone and all I have in the mornings is a pain here and the next morning a pain elsewhere. Currently it is a torture to sleep on it and I no longer look forward to go to bed anymore. <br> <br> Therefore I am no longer happy with the comfort levels and I am of the opinion that it does not live up to your advertised standards of comfort that is broadcasted so widely. <br> <br> Thus I would like to enquire as to how I can go about getting someone to either inspect the matress for premature faults or how to get a replacement for it.<br> <br> Thanks beforehand
