I ordered 3 of these in various sizes.  The fibers are course and some are loose, definitely not comfortable on the feet and could cause slivers.  The rubber nonslip grips on bottom are completely ineffective and rug slips everywhere.  I submitted a return for the first rug when it arrived and it will cost 12 to return.  Ill need to return the others also so it will cost significantly to return.  Very disappointed.
