This rug works perfectly in a large guest bedroom.  I read all of the reviews before buying but took a chance.  Have a vacuum ready when you roll it out - several silicone sachets had burst and we had a bit of a mess.  It was the only setback in setting it up.  I'd recommend a rug pad to help with keeping it in place since it is slippery on its own.  It won't harm wood floors on its own, which is welcome.
