It didn't work that well for me.
First, the zipper is delicate and I had a hard time closing it. I'm worried that if I take out the cushion to wash the cover, I might not be able to reclose it without breaking the zipper.
Second, I found the foam cushion to be too firm and uncomfortable for me.
Third, I had a hard time finding a comfortable location and getting the straps to be the right length.
Although it did get my head further from the frustrating headrest position, I ultimately did no...
