I am very picky when it comes to my rest. I don't like a pillow to firm or too soft. It has to be just right. That is what I found with the Cariloha Bamboo Gell Pillow. I have never felt so at peace when I lay my head down for bed. I sleep on my back and side and find this pillow works in both variations. I actually do think it is a bit cooler then other pillows I have.
