Based on my 2 week experience with this product so far, the firm density lumbar roll has the perfect level of support and firmness when used in recliner chairs. I find that in those types of chairs I have a tendency to slouch and this lumbar roll seems to prevent that, and plus it feels more comfortable too. I haven't found that it helps that much in my computer chair-- the chair back is pretty firm & so the firm cushion on the lumbar roll pushes me too far forward-- perhaps something less firm or one of the thinner D-shaped cushions might work better for me there.I haven't tried the cushion in the car yet-- for long car trips I could see it coming in handy as a way to change positions and alignment.Your mileage may vary, but for for me at least, I like the firmness and the cushion seems to be doing what I hoped it would.
