While on "vacation" I slept on a pillow at one hotel that was the most comfortable I've ever found.  I was a fool for not trying to buy it or at least find out where it came from.  

We've bought different pillows trying to find one that was as comfortable without success.  

My pillow seems to be soft when you first put your head on it but then soon looses all the softness and turns hard.  I use 2 pillows because I sleep on my side and if I use one I have a crick in my neck.

Does anybody have a pillow they'd highly recommend based on personal experience?
