Anyone who has stood on a hard concrete floor for longer than a few minutes will tell you how hard the surface can be on your feet, knees and back. Reduce the fatigue and soreness with the Buffalo Tools Industrial Rubber Floor Mat 2 Piece Set. The 3 ft. by 5 ft. flexible Rubber Mat is 1/4″ thick, giving you a large area to work on with plenty of cushion. The non-slip surface gives you more traction when grease and other liquids get spilled. Just spray it clean with a hose or power washer.
