Wonderful rugs!  Love that they are non-slip.  We bought them to help our old dog get around on our slippery laminate floors.  She had her own tracks through the house to get around!  The kids also think the 25 foot one is a race track through the house.  The gray color is a lighter gray, and matches well with the decor of our house.  I love that there are so many options for sizing as we needed a 25 foot one for the length of our kitchen/dining room, and a 10 foot option for a hallway to the front door.  Will certainly buy again if/when we need more!
