It is a great dense rug, it works well for layering. 
 I used it under a Turkish flat weave rug. 
It has held up well to light traffic for over a year.

We coated it with vectra,  have not needed to clean any spots. It's in a room that our animals don't go in, so not sure how well the loops would handle dogs. 

No shedding issues.

It arrived with some pink threads randomly dispersed through the weave. They would be covered by the second rug so we kept it. 

It's an off white with the subtlest yellow undertone.
