I was worried ordering pillows online without being able to see them. I had purchased new pillows for a new King sized bed at a local store and was so disappointed. They were too thick and dense and even after giving them "the break in period" I still couldn't sleep on them. When these arrived I was surprised by how lightweight and thin they were. I must say, I slept like a baby the first night trying them. They are nice and thin if you like to sleep on your stomach and I like how you can actually bunch them up. I would not recommend them though to anyone who likes a thick, dense pillow.
