USING ON HIGH PILE CARPET- CHAIR LEAVES DIMPLES ON CHAIR MAT MAKING IT HARD TO ROLL CHAIR OUT OF DIMPLES. SOFT VINYL. I DON'T EXPECT IT TO LAST- HOWEVER HAS A LIFETIME WARRANTY.
Looked on line and then went to the local store where an expert of chair carpet pads made the purchase for me on line. Information on line indicated the chair carpet pad was recommended for a carpet 3/4" deep or deeper. The problem is that it does move some when I roll the chair on it. Obviously I am disappointed and wished I had purchased one in the store that had longer longer cleats. Otherwise OK.
