Headrest for soft back chairs

Abstract

A portable, detachable headrest for easy attachment to a soft back or fully padded chair without a need for exposed framework. When the back of the chair is received between a fixed jaw and a moveable jaw of the headrest, the moveable jaw firmly compresses the back of the chair between the moveable jaw and the fixed jaw, mounting the headrest stably to the back of the chair. The headrest is adjustable in a vertical direction and an anterior and posterior direction, such that the user's shoulders and/or back have contact with the chair back in which the headrest is connected to.
