Bolster

A bolster is a long narrow pillow or cushion filled with cotton, down or fibre. Bolsters are usually firm for back or arm support or for decorative application. They are not a standard size or shape and commonly have a zipper or hook-and-loop enclosure. A foam insert is sometimes used for additional support. A bolster is also referred to as a cushion, a pillow and a prop. A bolster pillow is a common shape for lace pillows.
