The texture of the outer material is also important. Many mats have anti-skid backing to keep themselves from sliding around on the floor, and a pattern on top that keeps your feet from slipping.

We slipped a bit on the surface, particularly when it was damp, and despite the rippled texture on the back of the mat, it didn’t stay in place on the floor quite as well as others we tried.

The stone feels like textured cement ... there isn't much floor space. I don’t want the mat to get dirty with hair, dust or dirt (I have to sweep my bathroom floor often), so I find it best ...
