Hello, I have this pillow for 1 month and I must say I am truly very happy. I have cerebral vertebrae problems for over a year that prevented me to sleep before this pillow. Since purchasing this pillow I found a normal sleep and flexibility in the neck after a week. Before this I have tried many and all forms, only one shape memory has really relieved. It is true that the price is high, but worth it. I highly recommend it.
