This is advertised as indoor/outdoor rug, but I wouldn't use it outdoors unless you live in a dry climate.  It is a utility like rug, where the weaving is tightly looped.  It is not soft and fluffy, but not hard on the feet either.  Use a pad with this to protect your hardwood floors. 

Pros: Wears well (I've had it for a year and no loops have come loose with regular vacuum).  
Cons: Scratches hardwood finished floor if you don't have padding
