I wouldn't classify this as "indoor" as much as I would "outdoor".  I was actually a little bit disappointed in the quality - it seems 100% nylon/polyester ... looks like an Outdoor rug!!  I kept it and it's in my den ... but I will need to replace it one day and would like something that looks a little nicer.  (I mean quality) If you don't look at it closely you wouldn't know it was a cheaper rug ... so just keep your lights dim and you'll be good :)   Oh and the color goes well with white!!  Even though the lines aren't bright white ... you don't notice in a room with bright white accents.

Pros: Great style and color ... 
Cons: cheaply made ... looks nylon/polyester More OUTDOOR!!
