What type of mat do you use?

Hi FB world,

I have noticed that Erica has a much larger mat than I have and I'm curious about the types of mats used by others in this community. I started with a really thin yoga mat about 10 years ago and found that I needed extra cushioning, especially for anything on my knees. I found a thicker yoga mat and it's much better. But I like the size of Erica's mat and wonder if there are suggestions for mats that I can look into having - I want it thin enough for light yoga but my go-to workouts are strength and pilates when I'd use the mat. Thanks in advance!
