The amount of pillows a bed should have depends on the size of the bed. A larger bed will usually have three pillows on it, while a smaller bed may only need one or two.
A queen-size bed will generally have two pillows used for sleeping, but the sleeper may prefer more or less. A twin bed may only have room for one pillow, while a king can accommodate three pillows. Accent pillows can also be added for a touch of decoration, according to Martha Stewart.
It is also important to choose the right firmness of pillow to have a comfortable rest. People who sleep on their stomach will be more comfortable with soft pillows. Extra-firm pillows work well when the person sleeps on their side.
