The Original Casper Pillow is a down-alternative pillow that is soft, but also supportive. Its innovative pillow-in-pillow design features an inner pillow that is supportive, while the outer pillow adds a soft touch of fluff. Soft, yet supportive. Our innovative pillow-in-pillow design combines a supportive inner pillow with a soft outer pillow, so you dont have to pick one or the other. Fluffy, adaptive fill. Nearly a billion tiny fibers are blown into the pillow, creating an adaptive surface that supports you throughout the night no matter your sleeping position.
