we are thinking about buying one online, 5 yr guarantee, you can return it if you don't like it, £310 for 7cm, I have read about them on wikipedia, but would like to hear other peoples thoughts, not sure whether we should get a mattress topper or proper mattress , so any advice comments,
we've heard they smell, initially, are worried that because they are synthetic and so dense that we might get a bit too hot?
but anyhthing is going to be better than what we have at the moment
