I bought this because my previous pillow had become so flat it provided no support at all, and I was getting neck ache. There is a chemical smell as soon as you take it out of the packaging, but I just left it outside on the airer for a few hours and it has been fine since then. I have to admit that initially I was disappointed with this pillow as although I expected it to be firm, it really is very very firm, not even remotely soft for your head to sink in to. My husband tried it but found it too hard, he said he would knock himself out on it! I wouldn't go that far, but it wasn't quite what I expected. Having said that, I've persevered for a few nights and it is starting to feel more comfortable. I can't decide if I like it or not, but the one brilliant thing in its favour is that it holds my head at exactly the right height when I lie on my side, so that I don't wake with neckache at all. Hence the 4 stars, because I think the softness issue is a matter of preference only.
