Now the negatives:
This is not a mat in itself, but here a rubber carpet is cut into suitable pieces. A similar material is used as a rug on grass / gravel before caravans and campers. One can go comfortably on and sliding off guaranteed. However, the piece goods and costs a fraction.
For me also the thickness was not sufficient because it has especially in knees too little Damping.
I reoturniert the mat to Amazon.
