Unimpressed with the quality and appearance but came up with my own solution.  It  is woven but low quality polypropylene.  The green and blue are very prominent,  more garish than picture.  Ivory barely noticeable.  It looks very inexpensive similar to those you would buy at a discount retailer. But for the price wasn't expecting high quality but better appearance.  My solution instead of returning it, was to flip it over to the back where it has a true woven appearance, more similar to almost a colored jute/natural material.  I used a hair dryer to remove the label on the back.  I had no problem with edges uncurling by placing books on the four corners.  Looks like an outdoor porch rug.
