Really like this rug. Was easy to get to lay flat, just by unrolling it, laying it upside down and weighting the corners for about a day. My mudroom is apparently exactly 4x6 feet, so it fits without shifting. I used Gorilla Grip corner strips to be absolutely sure it doesn’t buckle and end up being a fall risk. It tolerates my terrier’s attempts at nesting in it, try to dig and scratch around. Will definitely go with this brand again.
