Excellent, does the job, but needs fine tuning.
Great cushion but the strap that is suppose to go around headrest isn't long enough. I drive a compact (matrix).  I still use it though but it falls forward when I get out sometimes.  Also the turn knob to adjust is the opposite direction the instructions mention.<br />Pros: This works great in conjunction with a seat cushion such as the wonder gel  Also suggest highly to have your seat straight up and keep your shoulders and chin back.  (Physical therapy) Overall though, I like that the back buddy has cut outs for the shoulder blades which makes me feel like I'm sitting straight up with proper support instead of a bulky car seat cushion
