Just thought maybe this would be great to discuss:
We used to sleep on bed mattresses made of more or less natural untreated stuff. But now, they tell you that you ain't cool, man, if you do not have a visco-elastic polyurethane foam (also called memory foam) mattress. They say this is the technological revolution in your bed, the Star Trek dream in your bedroom and the idea of the rigid mattresses is just a prejudice. It is being strongly advertised that the memory foam will remove your back, neck and articulation pains.
Millions of people have got a better sleep and life quality, according to the sites selling these products, and, in their published surveys, about 90 % of the clients vote for these mattresses. More than in the elections held in a Communist country.
