Pillow

A pillow is a soft object for putting your head on. Pillows are softer than heads, which is why heads go on pillows and not the other way round.^[1]

The cool side

Every pillow has a warm side and a cool side. The cool side is always the side you are not currently on. Turning the pillow over converts the cool side into the warm side within 40 seconds, a process known as the Pillow Paradox.^[2]

Fluffing

A pillow that has been fluffed is fluffier than it was before it was fluffed. It will remain fluffy until somebody actually uses it.
