I love this rug! It took me forever to order it because I was so hesitant to buy such a large item without seeing it first, but I am so happy I finally did. It’s a beautiful mix of dark gray, light gray and white and the design is so pretty. I didn’t need any kind of mat for underneath, it lays flat and isn’t slippery on the floor underneath. I love the different textures and heights of the rug in this design. If you’re on the fence like i was, go for it- you won’t be disappointed.
