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. In western countries, a bolster is usually placed at the head of one's bed and functions as head or lower back support, or as an arm support on furniture with high rigid sides. Bolster pillows are also used as bumpers in cribs and for lounging on the floor in family and children's rooms.
In the United States, "body pillows" resemble bolsters and are designed to be hugged when sleeping.
Etymology
The word is from both Middle and Old English, and is a cognate of the Old English belg, "bag". The first known use of the word "bolster" was before the 12th century.
Southeast and South Asia
In Southeast Asian countries, in particular Vietnam, the Philippines, Indonesia, Bangladesh and Thailand, the bolster is designed to be hugged when sleeping. In Vietnam, it is called gá»'i ôm ("hugging pillow"), while in the Philippines, the traditional tandayan is also colloquially known a "hotdog pillow" after the food it most closely resembles in appearance. Malays call it bantal peluk and Indonesians called it bantal guling.
In India and Pakistan, a type of bolster is known there as a lode (in Marathi), gao-takkiya, masnad masland, or paash-baalish/kol-baalish (in Bengali, and is used for back support aside from hugging during sleep.
East Asia
In China, it is called bà ozhÄ›n in Mandarin (simplified: 抱枕, "hugging pillow"), while in Cantonese it is known as laam2 zam2 (traditional: æ"¬æž•; pinyin: lÇŽn zhÄ›n).
Bolsters are called dakimakura (抱ãæž•) in Japan. Tradition suggests that a wife would fashion the bolster out of bamboo and give it to her husband when he travelled away from home so that he would not be lonely at night, hence the alternative terms "bamboo wife," "Dutch wife," or chikufujin (竹夫人).
In Korea, it is referred to as a jukbuin (죽부ì¸), from the words juk ("bamboo") and puin ("wife"). A jukbuin is used in the summer months to cool down while sleeping, since its hollow construction from thin bamboo strips allows air to flow through the pillow. A person tightly wraps their arms and legs around the jukbuin while sleeping.
