I bought this in the runner size to fit my super tiny hallway. I needed a rug pad to keep it stable. The colors are a bit more mute than what you see online, but I am not bothered. I needed an understated piece for traction for my dog not to slide all around. 
The rug weave is tight and loose in different places and that causes ‘bumps’. This rug will not lay entirely flat. I just got it a few weeks ago so I don’t know if it will eventually ‘calm’ down.
