I don't know how this can be described as an indoor/outdoor rug. I put it on my deck and when it rains, it stays wet for days so I have to remember to always wear shoes out there because water squishes up around my feet. It's a regular, fuzzy rug that holds a lot of water and doesn't dry quickly. And then hair and other stuff sticks to it. I'm rating it as an outdoor rug because that's how I'm using it--it would probably be different as an indoor rug. I just took this photo and it hasn't rained in two days
