I will start by saying this pillow has far exceeded my expectations. I really like this pillow and it has made a huge difference in my ability to sleep through the night. Compared to my other pillows, this pillow is a perfect firmness and gives a huge amount of support to my neck which tends to be my problem area when sleeping. I am currently looking to buy an additional one of these pillows for my spouse. The pillow cover provided gives a really nice cooling effect, and it seems to work for me being a side/back sleeper. I would highly recommend this pillow to anyone suffering from sleepless night or pain while sleeping.
