the concept of this pillow is great because I can customize it. It's really smart to be able to remove and or put back the memory foam according to the needs of my neck, head and body. Having neck pain and migraines due to my menstrual cycle, my need for support and softness varies throughout the month. I have tried many pillows in my life and I am glad to have found this customizable pillow. Some pillows gave me a headache and a neck ache which degenerated into a migraine. I now wake up feeling good in my body and without any feeling of aches or stiffness.Thank you Tempur!
