The most secure and the most comfortable mat money can buy! The EcoLast Dual Gripper mat combines the same quality, solid-core polyurethane technology as our Premium mats with high-traction technology. In addition to the rubberized traction strips found on the bottom of this mat, the EcoLast Dual Gripper includes four circles of dense carpet gripper hooks. These nonslip features hug tightly to floors and ensure that your mat will stay in one spot for as long as you want it there.
