I have had this rug for about a month now but I can not get rid of the wrinkles/waves from where it was rolled up. I have tried to flatten it by setting another heavy rug rolled up on the edges but it's not flattening out. Unfortunately, I passed the 30 day return limit, I am very upset about it. If this rug was in my primary residence I would have been able to return it in time, but I unrolled it one weekend and didn't make it back out to our vacation home for almost a month and even after trying to flatten out the edges- it still looks wavy and uneven. I am not going to be able to use this rug because it is a trip-hazard. I am very upset. otherwise it was a perfect rug- the color and texture matched the image on the site and I would have been very happy with it- but it seems like it must have been wet at one time while rolled up -- something has happened and the rug is warped; completely unusable.
