The fibers are woven in and not really stuck in the rug well. It is pretty but the fibers from the floral designs are really raised up.  I keep pulling them out of my infant's mouth!! I have gone over the rug a few times to try and remove any loose threads but she keeps finding more somehow.
On the upside, the rugs are nice and thick, reduce noise on our creaky hardwood floors. i would also mention that they dont even seem to require a non-slip runner.

Pros: nice looking, thick, do not need runners, non-skid
Cons: threads pull out easily, sheds
