This particular rugs pattern and color pallet is well suited for the space I wanted to revise.  I was truly searching for a piece that was wool or wool/silk blend.  This synthetic "option" does not have the plushness of the pile I prefer, but it the pattern/coloration integrates well within the space's existing aesthetic.  I've seen the same selection at another source, priced about 10% less.  That, however, is more than offset by the service and responsiveness of Wayfair.  
Thanks again for your competence and professionalism.
