The First night I used my pillow I noticed a huge difference. Before my hullo pillow I was waking up with horrible head, neck, and shoulder pain. No more! With my hullo pillow I am able to adjust it to how high or low I want it. It is soft but firm as well. The noise of the pillow does not bother me at all. In fact I find it rather comforting. The one downside I can think of with this pillow is that it is a bit heavy, but that is it! For people who are side sleepers, back sleepers and stomach sleepers I highly recommend!
I would recommend Hullo to a friend.
