Young Black Haired Girl Outside At The Wall With Pillows

A pillow is designed to provide support and comfort to the body and head. There are three main types of pillows; Bed pillows, Orthopedic pillows and Decorative pillows, with some overlapping of use between these. The appropriate size of a bed pillow depends on the size of the bed. In general a twin bed goes best with a standard pillow while for queen and king sized beds larger pillows recommended.
Beds
The classic bed pillow shape is a square or rectangle. In the US, they are common in these three sizes (in inches): Standard (20 x 26 inches), Queen (20 x 30 inches), and King (20 x 36 inches).
