Meh.

Because it's as airtight as one can get without being hermetically sealed, any air inside the pillow will billow up when you lay your head on the pillow. If you pay your head on it and then zipper it, then there isn't enough air in it to be comfortable. I had to give it up because it was messing up the angle of my neck when I slept. I am keeping it on the "extra" pillow on my bed (the ones not under my head).
