Jury is still out.  These are the softest pillows I have ever owned but that kind of screams cheap to me.  I'm not used to them yet.  My head sinks into them.  Conversely, my neck and shoulder haven't hurt one day since I've been sleeping on them.  Maybe I was buying the wrong pillows all along.  I always thought firm was best.  But I woke up almost every day with a stiff neck and sore shoulder.
