Unfortunately, I am not at all satisfied with the mat. When she arrived, I was still pleasantly surprised since she made a robust impression. After a week using already frayed from the edges and now after 3 weeks are the places where one is or is totally wobbly and it is almost on the floor. You can see right down to it my footprints and they no longer walk away. In addition, they squeak in total eg situps and Burpees she runs apart (ie is longer if you jump backwards). I'll probably get me another mat
