YR Yoga Mat Thick Large Exercise Mat 1/2 Inch 78"x51" Extra Wide Workout Mat for Home Gym, Comfort Yoga Mat Non Slip Floor Stretching Mat - Blue

I use this as a soft mat under a thinner yoga mat for Restorative yoga. It’s great for people, including myself, who need support under joints. It provides a soft and supportive base.

It was everything I expected in a mat. It's cushy enough to practice splits on without bruising your knees, & it's strong enough not to tear getting down into the split. I'm happy I bought it.
