I love to spend the night at my friend's house because she has the most amazing pillows and when I found out what kind of pillows they were I had to get one of my own! It is the most amazing pillow I have now! It doesn't get to warm even in the summer because it is a pillow that breathes, and it doesn't deflate. It is a spring-form material that isn't like cotton or like memory foam. It's a perfect in-between. And there are many different types you could get, for example: side-sleeper pillows, back-sleeper pillows, etc. Made a huge difference and will last! Worth every penny!
