This pillow is the best! I had pretty much given up on finding a pillow that works for me. Now, I get a restful sleep every night and love how my head stays cool. I had never heard about these kinds of pillows until I happened upon a NY Times article about pillows and several readers wrote in recommending the buckwheat pillow. This pillow is genius. I have recommended it to friends.
I would recommend Hullo to a friend.
