Hi everyone I was wondering is someone can give me some advice please. I bought a mattress in January of this year, it was delivered late in February 2013. Since then we have had nothing but problems with the mattress as it dips both sides and has ridge right down the middle of it. We were told by the manufacturers to turn the mattress round every week for 3 months to let it settle as it is pocket sprung. Please bear in mind that my husband and I are disabled but we found someone willing to do this for us. Now we are in June and it is still as bad as ever! We asked the company who sold it
