I love that the rug is wool as I was looking for a natural, non-polyester option. 
Two things are different though from what I expected, hence only 3 stars....
1) the colour has way more of a light blue tone to it than the silver/grey I was expecting;
2) the ivory lines are higher than the 'silver' parts, creating ridges. You can definitely feel them under your feet. This isn't a big problem but again, it is different from what I expected.   

I do still like the rug very much and the bold pattern works well in my space so it is a keeper!  

Pros: 100% wool and good quality.  Seems durable. 
Cons: Colour not quite as expected.
