Fusion™ Fiberfill: Fusion fiber is made from a polyester polymer with extremely high heat resistance. Each strand is highly polished to insure that the fibers move easily against each other to avoid lumping or clumping. Next, they are twisted or spiraled to give them a soft springy rebound when compressed in use. Finally, the fibers are joined in a conjugate fashion (symmetrical) resulting in a small cluster between one eighth to one quarter inch in diameter. The varying size of each cluster allows them to fit together and fill the voids between themselves providing a very comfortable sleeping surface.

Outer Cover: The ticking material used to cover the Nightingale pillow was developed specifically for the healthcare market. It is a light weight nylon fabric that is: waterproof, antimicrobial, stain resistant and anti-static.
