I love my chillow www.chillow.co.uk/2008/template/ as I get a really hot head at night. However they are basically a bit crap and bunch up easily so after a few months they don't really function. And they're really expensive.
I'm looking for an alternative to keep my head cool at night - has anyone tried a buckwheat or hops pillow? Other than that I'll have to get dh to wall mount a fan and direct it onto my head
