This is our 2nd Dash and Albert indoor/outdoor diamond-pattern rug. I got them both because previous rugs have been hurried to an early demise by our dogs. So far, so good with these. They look fantastic! Also, they do not feel synthetic or unpleasant underfoot. They can definitely be used indoors. I followed another reviewer's advice and got rug pads for this one and for our pale blue one. It does make a difference: the rug doesn't slip and it makes the rug look more substantial. We tracked some wet leaves and dirt onto the rug and the stain washed out with dish soap and water. Worth the money.
