This is not a rug. This is a mat. It is extremely thin and I still do not understand what it is made of.  The fibers are very thin and not densely packed.  The mat is actually a slipping hazard as you end up sliding across it like on a newly cleaned tile floor.  Because the mats fibers are so thin and loose it changes colour when moved, like those sequined pillows that show a different pattern when you flip the sequins.  The colour is way more brown and blue and very little green.
