So, I've had a tri-core cervical pillow since 2008 and I love it.  It is much more comfortable than any other kind of pillow and contributes to the quality of my sleep.  After six years, however, it was time for a new one.  I was a bit shocked at the price for a new one, but figured it would be money well-spent considering how the original helps with sleep and how long it has lasted.  I was disappointed, however, to discover that the filling seems to have been changed/cheapened.  The new pillow is far too light.  After just a couple months, the filling is already broken down and provides little support.  I have tried everything I can to  re-fluff it, but given the nature of the design and the non-robustness of the filling, that doesn't seem possible.  If I can find a way to clean my original pillow, I think I'm going to go back to using it - even though it's six years old.
