I have a lot of pain being on my knees since having had surgery a few years ago (not replacement), plus I have arthritis in both knees. This mat makes all the difference for me in yoga. I can get down on and up from my knees with far less difficulty....even this mat can't eliminate the arthritis issues with standing up from my knees, but it makes it so much easier. That means I can move between poses with far better speed and keep up with the class a whole lot better.
