Thanks for posting! It depends on the color of the decor in your room, but I am always a fan of a natural shag rug! One in a white tone could play well off of the other neutral colors in your room and not overwhelm the eye.
If you wanted to pull in the gray tones from the wall, try a rug like this one with a trellis pattern! They are super chic as is, and will complement and look great with a lot of different design styles and furniture options!
