STOP!!!! WARNING!!! Do NOT BUY!!! 
This is an outdoor mat and it stained my coral and travertine tile when it got wet!!!! What kind of outdoor mat does is this?!? I have NEVER heard of an outdoor mat that cannot get wet without destroying its surroundings!!!! I just completed construction on my home and it is brand new tile that may now need to be replaced!!! Absolutely HORRIBLE!!! Buyer BEWARE!!! Aside from all of this it came defective with an area lighter than the rest... simply terrible 
Update:
P.S the stain did not change at all with pressure washing. Now I am scrubbing with bleach...still stained
