I got the pillow as part of my late effects treatment for a cancer 12 years ago. My sleep patterns have been very disturbed and restless, normally waking around 4:30am. The Levitex pillow along with a conversation with James have changed dramatically my quality of sleep and to some extent my length of sleep. I forgot to take the pillow to our other house and my sleep patterns reverted back to how they used to be. I can't recommend the Levitex pillow enough, it has changed the way I sleep, but more importantley my quality of sleep has improved markedly, I can't explain why, but for me it has worked. Many thanks to you guys. Chris
