I love the design and it's a perfect fit under our kitchen table.  However, the bumps and wrinkles are not coming out.  I've searched different ways to try and get them out and have tried several (heavy books, stretching, steam ironing with a towel in between the rug and iron, and time) and they don't seem to be working.  Before I purchased the rug I saw some buyers mentioned the wrinkles and bumps were an issue for them but others didn't.  I was hoping I would be one of the lucky ones it didn't affect.
