We highly recommend that any good rug should have our high quality, reliable padding. The bottom side is made out of rubber and the upright side has a sand paper texture to provide traction. The paddings are cut 1 to 2 fingers smaller than the rug. At times, we cut it to curve with the rug.
A padding serves at least 3 advantages
1. Keeps the rug in place
2. Prevent stretching and curving
3. Rubber absorbs shock from feet and prevents premature wear
