LOVE this rug!!  I was nervous about purchasing online, but this rug is incredibly soft.  The fibers are dense and the rug feels quite thick and high quality.  I placed it on hard wood, so I did add a felt rug pad underneath, but a thin one.  The colors are beautiful; a true silver gray with some slightly blue-tinted gray in the darker areas along the edges.  The white is white, with some light speckles of beige here and there for the worn-dark to light look.  I placed it in an all white room with black doors and furnishings and it looks great.  The previous rug I purchased was called "white" online and came in an ugly ivory color.  So I was very, VERY happy with the colors on this rug being true to the online pictures.  The whole family loves it, including the pets.  We had a small accident on the rug and it cleaned up very nicely with wet papers towels, so it must be treated with something.
