good, sturdy massage
I've already taken back 2 massage cushions because they weren't effective enough.  This really digs into my back and feels great.  I have stubborn knots and tightness in my back and this is effective for those things.  There is no width control and the vibration feature is not really strong enough to make much of a difference for me.  I wish it was a little taller to get between my shoulder blades as I am 6' 1&#34;.  Other than that I am satisfied.
