I bought this mat for outside my front door. It is bright, fun and the coir makes it pick up dirt very well. It is a little course (helps with dirt, not great on bare feet), so I wouldn't recommend inside. The back is smooth and stops it from slipping. The "w" does not go all of the way to the end (even a bit less than pictured), not something for which I would return the mat, but it was noticeable. I love it, most certainly brightens up the front door.
