I bought one of these (from Sweep Dreams), and it wasn't what I was expecting. I thought it would be like polyester (you know, they make polyester fabric from recycled soda bottles, like fleece), but it was very plastic-y, shiny and slick. I couldn't tell that in the photos, so I was surprised. I used it indoors for a while, but it was too slippery (yes, I had a rug grippy thing under it). I moved it outside, and it started to disintegrate after a few months, with the weft fibers (more like very thin strips of plastic) just crumbling away from the warp threads. I was very disappointed. I wouldn't buy another one.
