It seems odd to write a glowing review of a pillow, and I have to confess that I got this free with a Tempur mattress rather than paying for it but I really would recommend this product.
I always used to be one of those people who scrunched up pillows, turned them over constantly, rearranged them during the night etc. It didn't matter if they were firm or soft, down or synthetic, they just never seemed quite right.
But these are fantastic. They work the same way as the Tempur mattresses, molding to your head, and offering extra support.
Like the mattresses, they are not cheap, but I think you get what you pay for. I can honestly say that the combination of this pillow, and my Tempur mattress, has markedly improved my sleep by a great degree.
