This is the ergonomic car headrest that allows a passenger to grab some shuteye during road trips without waking to a stiff neck. Its adjustable cushioned side pillows comfortably support your head in an ideal upright posture, preventing it from banging against the passenger window or bobbing side-to-side to interrupt your sleep. An included contoured memory foam pillow provides additional support for the neck if desired. Attaches easily to the posts of most auto headrests without any tools. Durable ABS material wipes clean. 14 1/4" L x 9 3/4" W x 5 1/2" D. (2 lbs.)
