We currently are using this in our house in hopes of cutting down on the dirt being tracked in this winter by the dogs and boys. 
In the summer, it will go on our deck. 
It will work great for indoors and outdoors. 
The colors are perfect and fairly neutral. 
It’s not slick, however it’s not getting too much moisture other than from shoes so that opinion might change when it’s outside. 
It does stay in place and has yet to slide out from underneath us. 
It’s thinner than an actual indoor only rug, but  it’s still very durable. The woven fabric is holding up nicely under a lot of foot traffic with no fraying yet. 
Great rug and I’m excited to use it outside this summer.
