Review on Large Dark Grey Indoor Entryway Rug - Non-Slip Absorbent Floor Mat For Front Door, 24"X48" Washable G-Shaped Door Mats - Ideal For Home Entrance by Ashley Slater

I really like this mat except it will not lay perfectly flat on my outdoor carpet on my porch. When I got it I put it in the dryer at the warm setting so I could get the folds out of it from shipping. It was laying prefectly flat but after serveral days of use it wants to get hills in it. I think my problem is it'is on indoor outdoor carpet and it moves thus a buckle in the middle. I wish the backing was thicker. It is a thin mat. I do like the absorbancy but do not loke how thin is. I may have to glue some sort of backing on it. May be fine for noncarpeted floor,, but it is thin.
