Query: Everyone should have this pillow

I've slept well at night. However, I've always wondered about this kind of pillow ... since they're expensive. For the past week I've had the best night's sleep in a long time. With this pillow I don't seem to wake-up as much during the night. I plan to get another ... and to get a few more as holiday gifts.
