I bought this rug because it looks great and has a very interesting pattern.  Though it looks pretty in person, it is quite thin for our taste so we did have it over a rug pad. We began to notice by the 5th day or so that there were random little white hard things that started showing up on its surface. Some of those things had carpet fibers attached to it - leaving holes in the area when we picked up the loose ones.  We returned it because we did not trust that the next one wouldn’t have the same problem.
