|Cleated: Has hundreds of tiny molded rubber studs that are primarily used to help hold the mat in place on most low and medium pile carpet.
In very sandy areas the cleated backing will separate the sand (which acts like tiny ball bearings) from the back of the mat and preventing movement.
The cleated backing is also effective in very wet areas as it allows a small amount of airflow under the mat to facilitate faster drying. This is also a benefit for use on expensive wood or marble type floors, which could yellow or become damaged by trapped moisture.
Smooth: A flat or burlap type texture is commonly used on most hard surface floors like cement, ceramic tile and terrazzo. The mat will best remain in place when the area underneath is kept clean and free from sand.
In very windy areas a smooth backing may form a slight seal on some floors and keep the mat from moving or blowing over. (During violent storms, it may be best to removal the mat to prevent any damage)
