one morning, about a year after buying a "luxury" foam mattress, woke to a stinging sensation in my right hip it took a few days to discover the cause the heat from the body activates the chemicals in the foam and then the chemicals are absorbed into the body phoned the company who sold me the mattress to my utter disbelief, the effects the chemicals had on the body are known by the industry when challenged as to why, when they know the mattresses cause physical problems, they continue to sell them, the person on the phone fell silent this is the "money mentality" at its brazen best haven't looked into the legal aspects, but the chances are there is a legal loophole which exempts the company from liability
