The quality of this rug was very nice, and it appeared to be durable, however after only a few months of outdoor use it began to disintegrate.  A bright blue powdery substance developed all over the surface of the rug.  Anytime we walked on it, the powder stuck to our shoes and feet and left bright blue footprints all over the deck.  We tried sweeping and washing/wetting but to no avail.  The only explanation is that the sun (it is in full sun for most of the day) is degrading the fibers.  Sadly it has been tossed after only one season.  We previously had an inexpensive outdoor rug from the big box (red circle) retailer that lasted 3 seasons in the exact same location.  The blue is also fairly bright, like a brand new pair of denim jeans, not a washed out faded pair.
