I bought these pillows a while back and I am tickled pink.  They are so comfortable and the gel inside really does keep you cool.  I am such a hot sleeper and these kept me at a good temperature all night long.  Not only is the comfort and cooling gel nice, the pillow is a heavy pillow.  Which I prefer. Heaviness isn't to be confused with the firmness. It is a perfect mid line firmness to me. I threw out my old pillow and will only use my molecule gel memory pillow from here on out.
