Let me tell you why...
the three stars are more on my part than Overstock's. Love the material and had purchased the 4' x 6' the week before for my bedroom. This was to go in the hallway. I should have paid more attention to the measurements. This is a throw rug, NOT a runner. In my definition, a runner is long and skinny (that you could 'run' on). This would then be a 'hopper' because that's all the room there is on it. Five stars for the rug as it is, and I love it otherwise. Ended up on the tile floor next to my bed, where it fits perfectly. What's the old saying, Measure twice, order once ;)
