Most rugs are backed with latex, but this one didn't say anything about it. I called to make sure it was reversible and was assured that it was. When it arrived, though, it turned out to have the latex backing. I would give it fewer stars because it wasn't as advertised, but the customer service was so good that I docked the rug only one star. I kept it because I was expecting house guests and needed a rug and because the representative discounted it enough to make it worthwhile. The rug looks good and I'm happy with it, despite the latex.
