I purchased this for photoshoots and used it 2-3 times, but I'm selling it because my baby no longer stays on the mat. It was folded for storage, so there are fold lines, but both the cover and the mat can be washed, so I think they will disappear if you wash and stretch them. angesmile Ange Smile Chay Navi Sunny Mat Color: Ivory Shipped anonymously.
