We have loved the colors (blues) of this striped low shag rug but not even a year out (10/20) the fibers have matted wherever we sit or walk. Part of it looks great as we don’t use the rug just opposite the TV.  Brushing or light vacuuming will not bring the fibers back up.  Disappointed as I love the look and colors of it. I guess polyester is not a great rug fiber.
