I have two large Fern Border rugs in Natural. They are great, I did have trouble with a stain that has left a slight discoloration. The natural color is much whiter than the color, natural, that shows on my computer. So I do wish I had chosen a darker color. It seems really sturdy, soft, and comfortable under foot.
Bought five years ago and in the natural (lightest color) and it's remarkable how stain resistant it is. Very thick and sturdy for the price. One reviewer mentioned that you don't need a rug pad as it stays in place, but if you have hardwood floors - use a rug pad ALWAYS to protect the hardwood finish. If you do get a stain - try a little tide mixed with water, saturate and place a white towel with something heavy on it over the stain. Keep switching out white towels until dry. Stain should make it's way onto the towels. My parents just bought one and like it as much as I do. I just recommended these rugs to a friend. Neutral colors a great option if you have a patterned rug close by and don't want to worry about coordinating.
