No. In no circumstance should Lloyd Mats be used above or below any other floor mat in your vehicle. All Lloyd Mats are designed to be “stand alone” floor mats. Floor mat anchoring devices either installed by the vehicle manufacturer or provided by Lloyd, are designed to secure one layer of floor mat. Additional layers of mats may shift into a potentially unsafe position without anchoring. The correct fit of Lloyd Mats depends on being placed directly on the vehicle floor.
