I utterly love this rug, so I'll start with the positive.  It's an amazing texture for any room, and the fact that it's real leather scraps means it's easy to clean and care for, and it goes with everything because it's undyed.  The downside and the reason for the low marks: it off-gassed for weeks after I got it, so odorous that I had to keep the doors and windows open as much as possible, and it still has a pretty strong scent a year in when you're down near it.  The scent does eventually go away, but it lingered for an extremely long time.  The other point against it is that the scraps are not universally well attached.  It sheds bits every time you walk on it.  I just toss them back onto the rug and it's not visible, but I've lost probably three dozen scraps off it since I bought it, and there's no easy way to sew them back in.  I'm definitely glad I bought it, in the end, though.
