I have another one of your mats, a Bio Foam one that I absolutely love.  I keep it in front of my kitchen sink.  I always wanted another to put in front of the stove.  My kids bought me the one with the red and brown flowers, thinking it was the exact same product, just with a pattern.  It is not.  The back side is very porous and does not adhere itself to the floor at all.  I've tried various methods to keep it from sliding around.  Most recently I bought some of your Gelly Grippers.  They work better than other things I've tried but it's definitely not solved the problem, just made it a little less annoying.  And yes, I have cleaned the mat and cleaned the Gelly Grippers.  Don't waste your money on this.  Spend a little extra and get the Bio-Foam.
