What were pillows made of
Pillows contain a filler made from a variety of materials including, foam, synthetic fills, feathers, or down.
Pillows were traditionally filled with straw. But since this was uncomfortable and rarely used today. Historically feathers and down were the choice of the rich; today artificial fills are the most common. The fill is surrounded with a cover made of some form of cloth or silk. Pillows on furniture normally include a zipper in this cover so that the fill can occasionally be removed and the covering laundered.
