Patent attributes
The pillow stiffener has an elongated cushion with a large rounded shape; two elongated arms each having a small rounded shape and being connected to and extending away from a long side of the elongated cushion. A flexible dull-finished web extends between the arms for retaining the arms at a fixed relationship with each other and with the elongated cushion. A joiner having the mentioned small rounded shape extends between and joins the extremities of both arms. Both arms and the joiner define with the elongated cushion a stabilizing rim around the dull-finished web for better retaining the pillow stiffener to a pillow. In another aspect, the pillow stiffener is made of a pair of flexible air-impermeable sheets and the elongated cushion, the arms and joiner form a single inflatable chamber.
