Due to having 2 Spinal Fusions in my neck, I always found it difficult to find the right pillow(s) to get comfortable with, and would often buy different ones of all costs, but would always find it difficult to settle down for a good night's sleep.  On reading the reviews (good and bad), the good seemed to sway me into buying one of the bamboo hybrid pillows for myself, and I can honestly say from the first night of using it, I have eventually found my perfect pillow! Due to the two fusions, I have limited mobility in my neck, but the hybrid pillow kept my head and neck perfectly aligned whatever position I slept in, and the heat dissipation meant it kept the right temperature throughout the night.  My partner was so jealous, I had to buy one for her too, and gone are all the old ones we had previously.  My only minor issue, is that I wished they sold the other covers, so you could have a spare one when washing the other. But that aside, I most highly recommend this pillow.
