Anti-fatigue mats and methods for making the same

A method for making an anti-fatigue mat, the method comprising steps of:

• S1 of providing leather comprising a first surface and a second surface opposite to the first surface, and forming a color layer on the first surface, wherein a color of the color layer is different from a color of the leather;
• S2 of cutting the leather;
• S3 of putting the cut leather into a mold having a plurality of protruding structures, wherein the plurality of protruding structures contact the color layer, and injecting an elastomeric material into the mold and curing the elastomeric material to form an elastic layer on the second surface and a plurality of concave structures corresponding to the plurality of protruding structures on the first surface, wherein the cut leather and color layer cave toward the second surface to form the plurality of concave structures;
• and
• S4 of polishing the first surface to remove portions of the color layer outside of the concave structures thereby obtaining the anti-fatigue mat.
