I got this pillow because I have some serious neck issues.  I need a hard pillow.  Tempurpedic pillows have become too soft for my use so I was looking for something stiffer and took a chance on this one.  I don't use it all the time because my symptoms vary from day to day.  The depression is a little too deep for a side sleeper.  On the whole it would be better if the depression was less deep for me.  Otherwise I do like it.  And I'm still looking for the perfect fit.  Not quite there yet.
